- Limiting solar export to the grid or your display showing LmtByEPM
EPM
The backflow settings on the EPM is probably the most important settings - it controls the limit of power the Export Power Manger will allow into the grid.
To change this setting do the following:
Press ENTER to open the menu
Scroll DOWN to Advanced Setting and press ENTER
Type in the code 0010 (DOWN, DOWN, UP) and press ENTER
Scroll DOWN to Backflow Power and press ENTER
Change this value and press ENTER
RHI-3K-48ES-5G RHI-3.6K-48ES-5G RHI-4.6K-48ES-5G RHI-5K-48ES-5G RHI-6K-48ES-5G

This is awesome, covered lots of great content in a small video. Thanks so much 🙏
Thank you. Hope it helped.
@@SolisNotSolis am enjoying the Solis inverter and the support team is actually very good.
Thank you Peter for this video, very well explained 👏
You are welcome!
Thanks for making these videos
Glad you like them!
Thanks Peter, these videos have really helped. I was hoping you could answer this, is there a way to set a priority order for charging and discharging e.g. when charging energy should go to my home, then the battery until full and then export to the grid, when discharging use the panels, then the battery and then import from the grid last. I’ve seen examples on my app of the inverter having an overlap of priority when doing these things.
Export Power is definitely on. Is there a separate setting somewhere for backflow power - I just get the backflow power setting screen, as I say, currently set to 0. Sorry to keep going on about this!
great video. I didn't know it consumes more if I disable Export.
Great series of videos. How do I know what DNO limit to set? Mine is currently set at 0 but is exporting.
Is your export power manager (EPM) set to zero then?
EPM is set to on but backflow power setting is zero. I think you set yours to 3600 kw. It is that setting I'm not sure of. @@SolisNotSolis
Ahh right. Is your CT clamp working properly? When you look at the main screen (or the app) are you seeing all four entities (PV, battery, house and grid) with valid values showing. i.e. can you add up PV (plus or minus battery dependent whether it's charging or discharging) and it equates to house load?@@user-iz8ti8sd5n
Hi Peter is there any way to stop the inverter from discharging whilst it is in a timed charge period ?
Hi. When it's on charge, it won't discharge at the same time. If you set your other charger (car charger for example) to match the charge times of the Solis, or vice versa, it will prevent drain.
I did try upping to 100kw (as per your video) but system didn't seem to like that and import/export was adversely affected so I put it back to 0 and it worked okay! I was wondering if I should put it up to 3500 but I'm concerned about about doing damage to batteries or something. Maybe I should let sleeping dogs lie.
You wouldn't put it up to 100kW (100,000w. The value is in watts, so you'd have 10w or 3000w or similar in there.
Sorry, yes I meant I did put it to 100W@@SolisNotSolis
Very Odd. And Backflow power and Export Power settings are both enabled?@@user-iz8ti8sd5n
Hi Peter, great set of videos you have.
May I ask, my setup is working well apart from a slight reporting issue. When I am exporting to the grid teh value of what is being exported seems to be included in my "self-use consumption".
Example: If I disbale backflow, my consumption is around 0.4kWh, and when I enable it it jumps to 2.4kWh, with ~2kWh showing as being 'exported to the Grid'.
Is this exptected and what you see or do I have an issue?
Hi Peter,
Mine was installed 2 weeks ago, 6kw inverter, most of the days I am not seeing any export, all that is produced is showing as house usage but I have nothing to use 3-4kwh, is there a setting in the inverter that must be wrong? Sometimes it shows all that is produced as export. I have a 10kw battery as well.
Can't post a screenshot....
Hopefully you can help.
Thanks
That sounds very much like the monitoring current transformer (CT) and modbus meter (Eastron or Acrel) are incorrectly placed or not working.
If you are seeing "excessive" household load that isn't there, it is usually because the installer has put the CT onto the inverter itself, or the household consumer unit itself so it isn't seeing the sum of the house load plus the PV at the same time. If you use Facebook, you could catch up with us over on the Solis group there were you can post some pictures of the install more easily? facebook.com/groups/288045168816481
Mine stopped producing any energy when I added these settings. Nothing was going back to the house at all, I changed it back and it I got power from solar back
CT in the wrong place? Needs to be at the meter
Thanks for this video. How do I spot my pure drive batteries discharging back to the grid in the evening?
Hi Peter,
With this setting set to 3600W as you show in the video will the inverter still be able to supply more than 3.6KW to the house when required?
Hi
It is indeed. If its say a 5kW inverter but export limited to 3.6kW it will still supply the house at up to 5kW
@@SolisNotSolis That's what I was hoping - thanks
Hi. Yes, all working correctly as you indicate. Exporting and importing at designated times too. Its just the the backflow power setting that is my concern. Leave it at 0 or increase it to ? Thanks. Roy Quiller
Curious. I've not seen one export with a zero limit in there yet. You see tiny spikes of export as the export limiter can take up to 5 seconds to act, but nothing sustained.
I'd consider upping it to 100w or similar and see what the overall day export looks like then.
Hi, what are the correct settings for having the PV charge up the battery with any excess? Then if there is excess after the battery is charged what setting do i need to allow the zappi to charge the car from the excess?
Thanks for your video Peter. I have heard (on Facebook group) that reducing the export to a nominal value ie 100W may damage or reduce the life of the Solis inverter. Is this true?
Hi Peter, I have no immersion inv nor EV, so I wonder if this tutorial suits me.
Hi. Assuming you're paid for export then you don't need to modify this.
Hi Peter,
I don't know why I asked someone else I may as come straight to the oracle.
I have an acrel acr10r meter monitoring my power and as you recommended a couple of weeks ago I have to move the CT to the main power input. Reading about it, the general consensus was "don't move it very far", and implication is I should use a certain type of cable.
I need to move it about 15 mtrs and I go to the local electrical facture and he says that not true.
What are your thoughts please.
Also I have a Pylon 2000(no suffix), can I cohabit a larger Pylon battery with this or do I have to start again
I followed your recommendations and I now see my battery contributing to the workload
Many thanks again
Gerry
Hi.
The accuracy of the CT is reduced if you extend the CT's cable. That is the reason for the RS485 meter (the Acrel) so the sensing is performed locally to the CT. You can extend the RS485 as far as you like - it will happily work over 500m of twisted pair. You should avoid extending the CT cables themselves if at all possible. 15M is too long for the CT in my opinion.
A US2000 will cohabit with a 2000c/3000/5000 fine. Just make sure the newer pack is the master.
@@SolisNotSolis Doooh what a div. I'm standing too close to the problem, all sorts of things happening in my rear view mirror.
One last thing for now, is it better to have more smaller capacity batteries or one large
Many thanks yet again
Battery makes little difference. However if you were looking at Pylontech, 2 x US2000Cs have a max charge/discharge rate of 50 amps. Whereas a US5000 which is basically the same usable capacity has an 80a charge/discharge rate. And is a little cheaper in £/kWh storage too. Although ruddy heavy!
@@gerrybaylis3916
@@SolisNotSolis I'm so sorry to bother you again with trivial questions, but I thought I was just dealing with an ethernet cable I now find to my cost.
I don't seam to be able to locate suppliers of 20 metre long RS485 ready made cables, I'm reduced to buying components from Ali Express to make my own, or is this the only route
Any suggestions please Peter
It's just a "network cable".
A quick Amazon search and you can have two for £7.15 in their own brand.

Configuracion OFF -GRID. Gracias
Hi Peter. We are in the unfortunate position of not being able to join the Smart Export Guarantee (Installer was accredited when we commissioned the work but they weren't by the time the did the work 🙄) So I'm not interested in exporting at all. Do you know what happens during the summer when the battery gets full, that is, what happens to the power generated that isn't being used?
Many thanks
Once the house load is satisfied and the batteries charged, your inverter basically lowers production from PV to support only the house load. Or stops completely if there is no house load to support. It actually looks like it's gone dark outside as it shows as no production from the panels, although in reality there maybe sun, but the inverter can't use it, so doesn't.
Hi Peter!!! Thank you for the recommendation steer on Facebook for a solis inverter!!!!
I’ve got a sparky no Solis experience know how! So really please you’ve done these videos!!!!
You're welcome although would've thought a spark would only install equipment they were familiar with!
@@SolisNotSolis true!!! He’s only been installing solar edge and giv energy stuff.
The company who fitted my current system couldn’t get it working for 6 weeks.
@@SolisNotSolis would you be willing to do a remote commissioning with me if I pay for your time?
@@rymoe6299 there isn't a great deal to do to be honest. The hardest part is getting the logger registered.
Out of the box Solis default is self use, aka typical household.
I've done a video on overnight charging if that's what you need too
I’ve got Solis hybrid inverter on order which will hopefully be fitted before Xmas 👍🏻
Hi, can the export limitation be set remotely either by the engineer or by Solis. I have a site that I hav e just been informed that requires a limit to be set to meet DNO requirements?
Hi.
Solis can, but the value hasn't been added to the "owner" account for configuration which is what installers presently have to utilise until the new Installer level is added to the management portal.
Can you use this as just a monitoring system of 2 inverters. Will this show the current they are both making combined. What is the default settings I don't want any export limit. Want it to export what ever it needs too
Hi. It only acts on the inverter you're configuring it on, and if you want to export as normal, just turn it "off".
Can the export power figure be adjusted remotely?
Yes if you ask Solis for remote management of the inverter
Hi, Is it possible to do this from the Solis cloud app? Thanks.
Hello. I'm afraid it isn't. This part is in theory at least installer only, so isn't given in the customer app view.
@@SolisNotSolis thanks for replying. Never mind, I thought that might be the case. I have a different inverter to the one you have so not sure how I would change it on there. Would a call to solis support work or do I need to go back to my installer?
@@donnabyrne443 Hi. Which model of "different inverter" do you have?
@@SolisNotSolis the model number is S5-EA1P3K-L
Rs485 failure how do I fix
Where is this being shown? It's likely to be the modbus meter cabling or type on a Solis.
@@SolisNotSolis no meter connection. If I put on no meter in advance setting alarm gose off. Will this affect my export to grid
@@Deneyboy1 Yes, absolutely. The modbus meter is critical to the operation of a hybrid
@@SolisNotSolis thanks for the info. Where do I get the meter and do I need someone to connect it . Can you send link. Cheers
@@Deneyboy1 Hi. You haven't said what model of inverter you've got. Or indeed why the supplied meter (they come with each inverter) was misplaced? Have you double checked all the packaging to make sure it's not hiding?
