- Is your Solis Hybrid Inverter showing an alarm MET SLT FAIL?
Check this video to reconfigure for the correct modbus meter.
The alarm "MET_Comm-FAIL" is given when the inverter does not detect the external Acrel or Eastron meter and it is expecting to.
"RS485 Fail" will also show on the screen between the inverter and the meter.
If no external Acrel or Eastron meter is installed, then "No Meter" should be selected by following this path: Advanced Settings - password: down, down, up, enter - Storage Energy Set - Meter Select - down button to highlight "No Meter" then press enter

Great videos, I Have referred to them often. Nice and straightforward, thank you
Thank you very much!
Thanks very much. I have no idea what any of this means but, thanks to your video, the problem is solved.
Hi Peter,
I have a Solis 1P 8K 5G grid tied inverter which is about to be installed.
Howerver it has been hanging around for some time and it seems that
according to package when sent there should have been a RJ45 connecter
and an instruction manual inside. I am not clear regarding connection between
smart meter[ I believe to be model DD1352] and inverter. According to Solis
installation instructions there should be a premade cable connecting to meter
terminals 5 [red] and 6[black] then connecting other end to inverter socket marked "CT"
[some internet videos have it marked "METER" the connecting cable I am choosing
is for, as in Solis diagram fig 4.23 Diirect Insert type. not fig 4.27 smart sensor"CT" type.
Do both "CT" type and direct insert type connect to the same port? Solis do not specify
Smart meter. Is the smart meter chosen [DD1352] correct for job?
I am not sure where the RJ45 connector fits in to all this.
As a near neighbour from Hudderfield I am deperate for answer as no one is able to give
me an answer.
Thanks.
Sid.
Hi Peter,
I have an acrel meter, the installers put the inverter on a secondary consumer unit, you mention the acrel should be sited on the meter tails, mine is position on the tails from the secondary consumer unit.
Is that a significant error.
Great information again
Best regards
Gerry
Hi Gerry.
Yes that is indeed an error, as the inverter can only see "itself" and anything else on that secondary consumer unit, so has no visibility of the rest of the house load and therefore cannot function correctly. It is super clear in the manual that the CT clamp has to be at the "source" of the house covering all loads including the inverter, and is installed fundamentally incorrectly if as you describe and will never work correctly. The most common location for the CT is (in the UK at least) the right hand live under the meter. However whereever you are, the CT must see everything inside of your meter, so is normally installed either immediately next to/under the meter. In some cases the cable types will transition between the meter and the run to the house, so the CT can be anywhere on that run, but must be the first thing between the meter and the first split of the live cable / consumer unit.

Wow I'm getting a full apprenticeship in a day.
The main meter is 10 metres away, is it sufficient for me to length the CT cable or does that degrade anything.
I'm beginning to see why they never came back.
Many thanks yet again
Gerry
The CT doesn't have to be at/under the main meter. It just has to be on the cable from the meter before anything else, i.e. either of your consumer units.
So you mention you've a second consumer unit. If you've (as I suspect) a meter at the "gatepost" and then a cable run to the house, and then the cable Y splits in some "junction box" before heading to each consumer unit, you can put the CT on the meter side of the Y split junction box.
Hopefully you've not two separate cable runs back to the meter post and it's one to the house which then splits somewhere you can gain access to?

How do i know what kind of meter i have. Are the meters you are referring to the small din rail meters on a electrical sub board? As mine are not branded eastrom or acrel.
Yes they are.
Thank you very much. Your video helped me to solve my problem.
You are very welcome.
Hello. is it possible to reset the acrel ACR 10r counter to factory settings?
Hi Sir, could you send the link store, to buy acrel meter 1 phase. Thanks
Hi Peter
Sorry to bother you with trivia.
Based on some of your past suggestions I've embarked on upgrading all of my fuse panels and circuit breakers. The inverter was connected to a 25A differential. It has now been renewed (I know what you are going to say "it's only doing it's job" ) but the rcd keeps tripping in the evening when there is no apparent load, only battery replenish time. Should this be an rcd or a normal circuit breaker. When I look at the alarm messages it's littered with 'no grid' messages. Before the new rcd it didn't trip and managed to recover but now the tripped inverter depletes the battery.
This morning whilst I'm recharging the battery, with the grid off, the panels recharge the battery nicely and soon as I reconnect the grid the direction of flow changes from recharging the battery to discharging by 1.2kw. with panels generating 2.8kw and a load of 1kw, even with no load the battery is being discharge at a rate of 1.2kw. There is no discharge time set, but it seems hell bent on discharging the battery
Is there an overall flowchart to help me understand what is happening?
Any ideas please
Hi. It is an RCD or an RCBO?
And what type is it (I don't mean the trip curve, which will probably be a B if an off the shelf device).
I mean is it an A type or AC or B or F type RCBO?
@@SolisNotSolis It says type AC on the front but I can replace it with whatever you think it should be
Many thanks
It should be an "A" type (or "B" type - subject to manufacturers specification)
Although I question do you really need one? Is the cabling exposed throughout it's run? If so then you wouldn't require one in the first instance.
@@gerrybaylis3916
@@SolisNotSolis That's what I was hoping you would say.
I find this sight the information you give out inspiring.
One last question for today I have an RHI-5K-48ES the max output is 3000W on the label. It was sold to me as a 5kw inverter can I generate more than 3Kw to the house
Many thanks
Best regards
Gerry
Hi. Not sure what the 3000w refers to and can't think what it would apply to on a 5kW unit to be honest.
But 5kW is 5kW to AC. And/or 5kW to/from batteries peak (sustained long term eg overnight charging it's more like 4-4.5kW to/from batteries)

How to add weather info to Solis inverter S6-GR1P5K-S, please?
Great videos, keep them coming.
I have a alarm code 186f4 any ideas 💡
If you pop into the log does it give any textual description? That's not one I've got in my lists, but I'll have a hunt
Hello,
I have a solis rhi 5k 48es5g, which is installed with 3kWp solar panels.
They installed this without a meter, but it works via an App.
Do you know if this meter is necessary to work with a battery?
because I now have a self-made battery attached to it with pylontech BMS, this should work, but if I, for example
When you turn on the kettle, the battery will not step in to take over the power...
Hi. The meter is absolutely required, as without it you've effectively turned your hybrid inverter into a dumb string inverter, as it has no way of knowing what the inbound or outbound power is at the edge of your house, and therefore doesn't know when battery power is required, or indeed when there is surplus PV to charge the battery.
I'd suggest you shout long and hard at your installers and request they return and finish the job. It is quite clear in the manual it is mandatory and not something they can choose to ignore.
Hope you get it sorted.
Thanks for making the videos. Can you make a video on the Solis App? I just wonder what it looks like and how much information is displayed etc?
Another query! If in the summer you are generating 4kwh and this is higher than the inverter rate of 3.6kwh (or whatever it is) does the rest go to the battery or is it lost?
Any help is appreciated. Thanks.
Hi. I can produce a run through of the Solis App - I'll put that on the list!
With regards the solar production, the 3 and 3.6kW inverters support 7kW of PV, and the 4.6/5/6kW inverters allow 8kW of panels.
Taking a 3.6kW inverter as an example, it can simultaneously produce 3.6kW of AC to support house load, and charge the batteries at 3kW (max), obviously subject to you having 6.6kW of PV in full production.
As per your example, if you had 4kW of PV at full output, and were using 1kW in the house, the remaining 3kW would go to the battery(ies) to charge them.
You would need a battery / batteries that supported a 65amp / 3kW charge rate, so Two x Pylontech US3000C's, which are rated at 37a each continuously.
Thanks for the reply. Much appreciated. I was getting different answers from different companies when I was asking for quotes. I did my own reading and I came to the same conclusion as your answers (so went with that company) but it’s good to get it confirmed!
Yes, thanks for adding it to your list👍
It's seriously worrying some companies installing Solis inverters don't actually understand the functionality - however your conclusion is spot on, and demonstrateable in a number of installs, including my own.
Thanks for the replies. Yes it is worrying! Sorry another question - Can you change the charge times on the online solis management system or only at the inverter itself?
@@russellstewart5194 Yes. Drop Solis an email and ask for remote management to be enabled. They need your email address and inverter and data logger serial number. Takes a few days at present
With exception to size is there any difference between these 2 units?
As far as I'm aware, it's merely a model refresh. We've installs with both and never had an issue, save one dead on arrival meter out of the box.
Hi, at around 2.20 on your video the code LmtByEPM appears on the status line - I'm getting the same on my system and I can't get to understand what it means or why it occurs - can you shed any light on it for me please?
Hi. It is when you've an export limit setup and the inverter (briefly) reaches it. It will happen on and off during cloud passing and loads changing if you've a limit enabled. Absolutely normal and nothing to worry about, assuming you've intentionally set an export limit.
