How to set up self-use and if needed time of use to set charging times on RHI hybrid inverters
1) Make sure you have the right battery selected on the inverter.
Advanced Settings (password 0010)--Storage Energy Set-- Battery Select
Set an Overdischarge SOC of 20% (value down to which the inverter will discharge the battery) and Forcecharge SOC for the battery of 15% (value bellow which the inverter will start charging the battery from the grid.
2) Select the correct type of meter
Advanced Settings--Storage Energy Set-- Meter set--Meter Select--Single phase meter (Acrel) or Eastron single Phase meter
3) Set Storage mode to self use mode
Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use--ON
Make sure the other modes are disabled
4) Enable charge from grid function
Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use-- Charge from grid--Allow
5) Set time charging to ON - if the customer needs to charge battery during lower tariff periods (for example during night time)
Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use-- Time of Use--RUN
Select a charging time to include the current time to strat force charging the battery
Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use-- Time of Use--RUN--Charging time
In this case you don't need to select a discharging time. Just set discharging times to 00:00-00:00
6) After all, this is set, I suggest turning off a load and checking the inverter's behaviour.

Much appreciated! First day with my inverter and your videos have been great
You're very welcome. Happy cheap rate electric!
Amazing, I was just looking at this on my Solis 5G, having read the manual and watched a couple of other videos, I was none the wiser. You've just answered all my questions and a few I didn't know, I didn't know.
Thanks, I'm now off to watch all your other videos.
Cheers Steven. I've a few more in prodution too..
@@SolisNotSolis Brilliant, there is a whole load to learn to get the best out of these systems.
I look forward to more videos, I have subscribed.
Your videos are extremely useful and you explain everything succinctly, thanks.
Thank you!
Really useful series of videos, had a pro lem with the system not charging, think your vid showed me what was wrong, thanks for the help
Thank goodness you did this video, very helpful, thanks.
What a fantastic site. Thank you for this information. Its just what I needed and its incredibly easy to follow.
You're very welcome!
Really helpful,simple and direct. Highly recommend
Great to hear!
Brilliant, thank you very much.
Peter thanks for you training videos very helpful
Very welcome!
Thanks for this video - just had an inverter and batteries installed but little to no info provided on how to control the charging of the batteries.
Great video thanks. I'm confused though. If I'm charging from the grid at 230v with a 5.6kW inverter isn't the charge rate 5600/230 = 24 amps, not 50, or 100amps
Hi.
You are charging at approx 50 volts (the rough battery charging voltage) so at 100 amps multiplied by 50v gives you a 5kW charge rate.
However 5kW at 240v = 20.8 amps (plus a bit of loss. You'll usually see the inverter draw around 22 amps at AC when charging at 5kW).
These videos are a god send!
Thank you!
Great, thanks Peter.
Thanks for this video, very helpful. One question for you. I am set. up for self use, and the Optimal Income is set as STOP. However, my battery is still discharging to the grid at times, when I thought STOP would prevent this. Is there another setting I have missed ?
Great video , many thanks
Can I ask which grid provider do you and other viewers use ? Octopus dont have a cheap overnight rate (unless you have a car).
Octopus have just started to offer a cheap overnight rate.
Thanks for the video. Had my Solis 6kw inverter installed today and I can set to self use, but I don't get the set the time function - any ideas what I'm doing worng?
Thank you for this sir!
You are very welcome
Thanks for these great videos Peter, very informative.
I wonder if you or anyone can answer something I'm struggling with, just a concept at the moment but I was wondering about Tariffs such as Octopus Agile where they pay up to 60p/kwh to export at peak and have a flat rate of around 33p for importing. In theory it would be beneficial in winter when there is hardly any PV generated to charge the batteries at 33p and export at peak times to make some profit.
The problem is how to stop the Solis from using the cheap stored energy to the house until it's ready to export at the peak rate. Any ideas?
You'd spend more on batteries than you would ever earn from the import/export differential.
Very useful, my inverter only has a 2 line display but hopefully I will be able to navigate to a similar setup.
Edit. I completed the setup for overnight charging OK. I assume when the sun starts to shine I only need to change the Time of use from Run back to Stop to only charge from the solar panels?
the application “inverter sonis” on the mobile was working then stopped and only show me how much the mirror is making electricity. if there is any video explanation that I can watch. thank you in advance
Thank you . Any videos on how to use the phone app to do the same job
Hi Peter, thank you for your videos, very helpful Do you have any experience of retrofitting a Solis Hybrid Inverter and Pylontech batteries into and existing FIT registered PV set up using a bi-directional Emlite ECA2.nv meter?
Hi. Solis hybrids have a bi-directional AC charger built in. If it sees surplus via it's modbus meter + CT, will start charging from that surplus. It does not matter where it comes from. You require no interlinking/config/otherwise, it does it out of the box when installed as a standard hybrid with batteries.
@@SolisNotSolis Hi Peter thank you for your reply. I need the bi-diectional meter to continue to claim FIT. as I am charging from the grid at night and from PV by day, when there is some the bidirectional meter NET reading should be my PV generated electricity but I am keen to talk to some one who has such a set up to understand it better.
Hi Peter great set of videos very well done. I note on your video that your Inverter screen has 3 Charge and Discharge times. My Inverter screen only has one but I need at least 2. How do I get the extra Charge and Discharge times to show on my Inverter Screen. Thanks in anticipation
Thru updating the inverter
What configuration should I choose when I have nissan leaf 48V lithium batteries?
Hi, would this inverter support Trojan trillium leisure lifepo4 batteryies (48v) ? Is there an option to set own charging parameters? Looking to buy 3kw hybrid
Thanks for taking the time to do these videos Peter. Can I assume that if your battery was a single Pylon Tech 5kWh, it would be better maybe to not hit the battery with 95 amps, instead use the fact that you have nearly 4 hrs. to charge and give it a gentler say 26 amps? What do you think? Is this better for battery longevity or is this not an issue.
Hi Pablo. A single US5000 is a 50A continual charge/discharge rate, so you need to set your rate to 50A or less. It will take two hours to charge at 50 amps so you may struggle a little if you reduce it as far as 25A, as you'd then take four hours. Perhaps somewhere in the middle if you're looking to get the absolute best life from your battery.
@@SolisNotSolis Thanks Peter. Thats something that I had not realized when ordering a single US5000. So, to get the full 5kW potential output of my 5kW hybrid inverter then I really need 2 US5000's?
@@Pablo-tw7tt Hi. That is correct. you'd need two minimum to achieve a 5kW sustained output
@@SolisNotSolis Hello Peter. I checked what the BMS was telling my Solis 5k Hybrid via the CAN Bus and it shows that my US5000 is capable of 80 Amps (charge/discharge). A quick calc indicates that the battery should be able to support approx. 3.8kW. Does this sound correct to you, or do you think it may only peak at this level for a short period?
@@Pablo-tw7tt Hi. I also spotted this late last week. Upon checking the manual with those particular batteries, they also showed 80A rate, although I've seen no official notice from Pylontech about a change in specification. And the inverter they were being connected to showed 80A too.
There is also a separate peak level in the manual (I haven't got one to hand) but believe it was double 80, so I don't believe the inverter is showing a peak value just a standard charge/discharge rate.
I set my solis inverter to charge at cheep rate and to discharge during the day and it worked for two days. This morning I adjusted the timing and now the inverter won’t discharge, I wonder if it will attempt to charge tonight?
Hi there. These videos are great! Thank you! If I can ask, my battery and my EV charge on cheap rate from 2-5am but then, once the battery is full before 5am, the inverter starts directing the battery power to the EV. So, by 5am, the battery is almost empty again. Do you know if I can change this in the settings?
Need to split ev into it's own and only put ct clamp for battery onto main house fuseboard.
thanks for this, got my solar and battery installed yesterday, just setting the inverter to charge my foxx5200 overnight hopefully it works as my inverter is in the loft and its a pain to go up and down, shame you cna't do it on the app
Hi. If you email your Solis regional support centre, stating your registered email address for SolisCloud, plus the serial number of the logger and the inverter, they can enable phone/mobile app based management for you.
@@SolisNotSolis thanks i have the app but can't see where to change stuff, another question if you don't mind, i have foxlv5200 battery which says recommend discharge 50a, and max charge/discharge 100a
should i leave them both at 50a ?
thanks
@@stefanhorn6780 Hi. You need to specifically ask for those options to be enabled in the app before the buttons appear.
If you've only one LV5200 and a four hour charge window, then there is no reason to take the charge rate above 50 amps.
@@SolisNotSolis this may sound like a stupid question, but i will ask any way, does it take 5kw to charge my 5kw battery from the grid ?
@@stefanhorn6780 You've mixed values here fella.
If it's a 5kWh battery, then it takes 5kWh (plus a little for losses) to fully charge the battery.
That can be at a current rate of 1kW for 5 hours. Or 5kW for one hour (subject to the max charging rate of the inverter and battery of course)
Thanks for the great videos.. once you set the charge time..will that stay the same everyday? Or do you need to enter it everyday? And I assume same scenario for cancelling the charge time ??
Hi. Those figures are sticky. Whileever "RUN" is enabled at the top of the Time of Use screen, they'll run daily with no further action. If you wish to suspect it for a night or two, just change RUN to STOP and leave the times in the charge fields. They'll just be ignored.
Great video and I discovered a feature I didn't know about. I would like to know if it is possible to set this solis to work even in the absence of electricity. Thank you
Hello. There is a "EPS" output which has a variable capacity dependent on the inverter model.
This is permanently live, powered from battery.
The batteries can also be charged from PV while the grid is down too.
Attention, store and redelivering to the grid costs ~27% loss of power ! ( 48V/dc batterij too 230V/ac grid = +/_ 27% loss)
Thanks for this video. Do you know if you can do this via the app. My 6kw hybrid inverter is in the loft so don’t fancy a trip up everytime I want to set this. I have a 7.6kw array and 3 x 3.5 kw 3000C. Will change my amps to 95 too. Currently at 50 I recall.
There is a add-on to the normal ap which activates the ability to set this up. It's called inverter remote control application: you should be able to access the application form on Solis Support. You will need to fill in your plant id and inverter serial number. They will give you a ticket and will reply in a short while with a link. Be warned it is a horror to use and none of the terminology is the same. However, set it up first on the inverter as shown in the video. Once that is done you can change the times with this app through (in the app) inverter control>work mode>self consumption>charge and discharge.
@@graemewilliams1553 Thanks, Support gave me access this afternoon and ive sorted it. My thinking was to leave the battery times the same for charging just to switch it off on on depending on the weather and season. Still getting used to it all but the remote access is essential for my setup. Thanks.
Planning on setting this up today. 4xUS3000c with 3kw hybrid inverter. Data sheet for battery says charging is 37A. I note on my BMS the rate is set at 148A (I presume 37A x 4 batteries). When setting my charge time do I use 37A for the charge rate, or 148A?
Your max charging rate is 60a on a 3.6kW inverter or 85a on a 5 or 6kW inverter. On paper the 5 and 6kW inverters will charge at 100a rate, however they won't sustain it for hours on end.
However if you've got a 4 hour cheap rate, 85a is more than enough to fill your batteries.
85a x 50v =4250Wh. Or 4.2kWh. X 4 hours gives you over 16kWh of charge potential within 4 hours for 14kWh of total battery capacity based on 4x3.5kWh batteries.
What should 2x us2000 be set at on the discharge and overdischarge limits?
Hi. Are they just us2000 or us2000c with the trailing c being pertinent?
Thanks for your helpful video. I have a Solis RHI-5K-48ES-SG Hybrid inverter and 3 nr. US2000 Pylontech 2.4kWh / 50Ah 48v batteries. I have checked the BMS Info panel which gives a charge limit of 20A and a discharge limit of 75A What therefore would be the charge/discharge settings for the self use panel - (Is the BMS info for all 3 connected batteries or just for 1) Should the self use panel be set to 20A charge (75A discharge if exporting) Thanks.
Hi. As its a 5kW inverter, both values should be 75a. As you suggest 25x3.
I have 4 US2000 Pylontech 2.4kWh, does that mean it should be set to 100a?@@SolisNotSolis
Hi. If it's a 5 or 6kW hybrid model, then the peak charge / discharge rate with 4 x US2000s (25A each) would be 100A
However that is the peak rate. That's fine for short term loads, so assuming you aren't bulk discharging to the grid, then discharge of 100A (to support your house load) is fine.
Sustained charge (e.g. overnight cheap rate) tends to get the inverter pretty hot, so I'd usually suggest setting a charge rate of 80-85A so as not to over-stress the hardware. And if you've got a 3+ hour charge window of cheap rate, you'll comfortably fill 4 x US2000 at 80A in three hours. @@googlelansdown
Hi, Thanks for the informative video. I have a Pure Drive 5Kwh battery. I have set
loading for 2 hrs (0200/0400) and max 0.50 loading, disch 0.25. When I did not set this, in the moring my meter was approx 0.95p, whereas now is 1.45. Do I get too much from the grid, then, I wonder?
Hi. When you say "disch 0.25" do you mean you've explicitly configured a discharge window on the above time of use screen? If so that literally means "empty my battery to the grid"
It doesn't as some might expect, mean "support house load".
The inverter explicitly supports house load when set in self use mode, you don't want a discharge window configured at all.
Just a charge window for your cheap rate period.
@@SolisNotSolis Thanks for your prompt reply. Sorry, I am a complete newby on this subject. No time set, but only Discharge Limit 025.0A. Time for charge limit 040.0A (not 0.50 my mistake) was set from 0200 to 0400.
So if no discharge time window is set, ie duration zero then that should be fine.
Great video, I did this and had several nights of successful charging from grid… I need to charge my car and was told priority would be given to the battery but I need my car to charge.. so I went to change Run to Stop on the page with the charging times in run time menu and now my 7kw battery charger makes the inverter whir and then it turns off… I haven’t changed anything else, what can I do to make my car charger work again… any ideas please?? Thanks
I dont know much about this but would say you should have your car charger on a separate circuit, consumer unit (essentially not connected to the inverter)
Hi Peter, great video.
I've followed these steps and I am now finding my batteries won't discharge.
I am currently sitting with 97% charged batteries but pulling from the grid for my usage.
Any advice on what settings to check or change?

Thanks
Hi Pete. Great name. Only the best sir!
On a 3kW unit, you'd have a max current of 62 amps on either the charge or discharge fields, just as confirmation.
Did you double check that you were in "self use" mode on the initial screen?
And that "run" is selected rather than "stop" on thetime of use screen?
And that you've no timed discharge durations, i.e. all Discharge lines are showing zero duration on the right hand side?
And finally I guess, can you confirm your inverter was operating normally before you made the change for overnight charging?
@@SolisNotSolis great name indeed 😁
It was all working fine before I've changed the times.
Self use in set to run, charge times 2131-0229hrs (Go Faster).
Discharge 0000-0000.
Charge and discharge rates set at 50.0A
@@petergjohnstone Ahh. I spot the problem. The clock doesn't support going "around the day". It's a bit err "dim" in that respect.
Change your time windows to 21:31 to 29:59 and then use a second charge field for "00:00 to 02:29"
@@SolisNotSolis I will give that a try now. Thanks
@@SolisNotSolis just checking, the batteries are charging but they won't discharge. Will this tweek to the settings make them supply the house?
Hi Peter Great video, I have solis hybrid 5KW with max 100A charge discharge rate and two fox 5KW batteries with a max charge current rate of 100A what should charge limit be set at? the installer has either set it at 50A or has left It at the default settings? any advice would be appreciated.
Hiya.
In theory you can up it to full 100 amps charge rate. But extended periods of high rate charging tend to make the inverter get super warm and then throttle the charge while it cools down.
If you turn this around and consider your charging window of time. Let's call it four hours.
10000w (10kW) divided by 48 volts divided by 4 hours gives you a required charge current of 52 amps.
Ideally you want maybe half an hour spare at the end of charging for the batteries to equalise all thr cells. So with that in mind I'd probably set 65 amps.
That means you can start and stop charging 5 mins after cheap rate starts and 5 mins before it finishes, still have full equalised packs and reduces the strain on the inverter and the batteries for longevity.
@@SolisNotSolis Thanks Peter I have actual 5 hours of cheap rate( Octopus Go Faster) 8.30pm till 1.3am. so if I set it at 60 I assume I would be charged up.?
Yes more than comfortably.
@@SolisNotSolis thanks Peter, woud you be able to do a video on how to train wife/parter's to use high energy appliances during cheap rate tariff times? I am sure this would be a a great benefit to our country in these difficult times.😀 I fear that you this will be more difficult than a Solis training..
@@AndrewWhitaker I think that is beyond me I'm afraid 🤣
Is it possible to change timed charge settings remotely, ie not using the inverter screen. Either through the app or SolisCloud.
Yes, if you request remote management from Solis.
Is it possible to NOT charge the Batteries and to NOT discharge the Batteries between set times?
Reason :- i have cheap rate overnight. But in the summer i can get enough solar to run the house and charge the batteries a bit, as long as i don't use any battery overnight.
However i use 5Kw overnight on average (Heat pump and Hot tub) which can use overnight electricity.
But if i don't allow charging from grid, it will discharge from battery overnight (meaning if it ends up being overcast the next day, i could run out of electricity and then have to use high rate.
So really i want to use battery/solar from 05:00 to Midnight, and use cheap grid Midnight to 05:00 to run the house without draining nor charging the batteries.
Hi. Yes indeed. Set a discharge window of 00:00 to 05:00 with a current of zero amps.
@@SolisNotSolis Thank you.
I've gone into my solis and it says 50A on both any suggestions it's an rhi-3p5k-hves-5k with 3x us3000cpylon 3.5kwh batteries any suggestions ?
Pylontech US3000C series are not supported in series configuration for HV battery system inverters. While you can potentially bodge them to work, they aren't designed for it, and specifically state they are for parallel use only.
For that reason I'm not going to answer your question I'm afraid, as it's somewhat dangerous and out of product spec for the batteries. They aren't even HV rated terminals...
Hello all. I would appreciate some advice please if possible. I have a Solis 6kW hybrid inverter.
On page 3 of the Information screen, it tells me that my battery charge limit is 20 amps, and my battery discharge limit is 200 amps.
Are these figures normal, or do they need to be altered, and if so, how is that done.
In the Advanced setting. the charge limit is set to 100 amps and the discharge limit is set to 50 amps.
Are all those figures in conflict with each other. or are they ok.
Thanks in advance for any info.
Hi. The battery charge limit will/can be reduced if they are (near) full or too cold. Could either of those apply?
Hi Peter. The batteries are almost at full charge right now, so your message above explains it. I was trying to figure out what to do from watching your video.
In the Advanced setting, are the figures normal for charge limit of 100 amps and discharge limit of 50 amps. Thanks again for all your help with this.@@SolisNotSolis
Hi. Glad we've explained the charge current limitation.
Although your discharge rate is too low. 50A x 50v (nominal battery voltage) is 2.5kW.
You need to up the discharge rate to 100A too.

I have a 5Kw inverter so I have set charge limit to 95.0A but I also want to discharge to grid. What should the discharge rate be set at? Thanks

Hi. If the figures have dropped that low its likely that the batteries have gone in performance crippled mode due to their temperatures. Are they likely to be below 10 degrees. That's the usual point the capabilities change.
@@SolisNotSolis they were installed in the garage, should I cover them?
Hi. It is probably worth graphing the battery charge limit parameter which you'll find under the graphing options via Device - Select inverter. Scroll down a page to thr graph. Parameters and it's the last option under battery.
If the charge current limit is seriously down there, eg down to 20 to 30 amps as you suggest, but more than likely up at 200a when they're working hard, then you know it's temperature related.
If so, some enclosure and a foot long heat tube with thr thermostat set super low eg frost setting inside would get you back in business.
Even mine are suffering today although only the top pack in each stack as the lower ones are keeping each other warm enough.

Thanks for that information. But I fear that charging my car at the same time as the batteries would exceed the maximum load to the main supply fuse which is 80 amps. The car takes 30. And the background usage in the house adds another 2 or 3. I think I will restrict the battery charge to about 40. I know CT clamps and a priority switch would prevent an overload but as long as the solar batteries are fully charged before daytime power rates kick in all should be well.

You can apply for remote management of your inverter over on the Solis site, and you gain an extra button at the top of the app that allows you to set various parameters, including the times and turning the charging on and off. Once Solis have activated it, you need to log out and back in to the app for it to become effective.
