Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Peaked at 63 today and no sign of throttling,
Its in a loft (upstairs in a barn for the townies) so sorta outside. Highest ive seen is 65 in June. The panel temp is for sure reducing output though.
I hit almost 65c yesterday on a Solis-1P3.6K-4G but no obvious scaleback on power output. I stuck a fan on it today and it never went above the mid 40's and the power curve remained the same. Going by the docs I'd have expected a serious reduction in output so not sure what's happening.
I think the general consensus is the Solis inverters don't have a built in fan, it sounds like a fan but is something else that kicks in when it's under high load. I couldn't find any specs on them that mentioned a built in fan. It was debated for a while in one of the threads somewhere.
I was up there at one point to tweak some settings on the Eddi, and the fan on the inverter was running.
You need to get a fan on it at that range if you can.
Mine hit 68.5c internal temp today. Attic temp got up to 31.4c.
I have seen my Solis go up to 58-59c with no issues before I turned on a fan to bring it down a bit. In truth it probably went higher unnoticed. Am I wrong in thinking it is ok up to 65-70c then allowing the 20-30c it mentions in the app up to a max of 105c? I will leave it up to the experts to educate me now. 😂
Inverter internal operating ambient temperature
45.6℃
(up to 105℃)
IGBT (Core) Temperature
IGBT is the device with the highest temperature inside the inverter. When the temperature is lower than the maximum withstand temperature, the inverter can operate stably and reliably.
Inverter Ambient Temperature
The inverter ambient temperature is the air temperature inside the inverter.
Note: normally, the IGBT temperature is 20°c to 30°c higher than the internal ambient temperature of the inverter
How's everyone's inverter temperature fairing in this weather? Mine peaked at 43c, just 2c below the throttling point.
I picked these up at the local co op (Topline) last year ENER-J SHA5264

was able to flash them with tasmota. They also have a 16 amp fuse inside them.
Meross ones, make sure you get the one with power monitor, available on amazon.
Thanks. I signed up for IOT platform at the start of April this year. 1 month later they asked for a subscription, but difficult to see how much (it wasn't going to be free though). I sent them a note asking for more time as I was "evaluating their platform for a project/product" and they gave me a 6 month extension. That'll be done at the start of Nov, so will have to get a different way. Maybe the fact that you were on it earlier put you on a different plan.
Anyone else had similar experiences with Tuya devices in HA?
I use about a dozen wifi sockets around the house, and these have been great as they do power monitoring (I automate off their power consumption in HA), are 13a and are cheap. https://www.amazon.co.uk/dp/B09QQCWVNN . May have to try that tuya-local or give Tasmota another go on them.
Any recommendations for other brands that do power monitoring, 13a, (ideally locally) controllable in HA, and won't break the bank if need to buy a load of them? I think some are using the Tapo ones. I assume they give real-time power monitoring in HA?
Yeah, through the tuya iot, never had any issues. Had originally signed up for it.. in 2020, when I got some smart plugs that I was looking to control via node red. Never seen anything about a 6 month grace
Then realized that they didn't have power monitoring. And went into a drawer
I do have tasmota on the ener-j smart plugs though.
Will look into the tuya local too.
finally got my hands on a v2 solarman data stick and have been able to integrate the solis hybrid inverter + battery as well as the zappi/eddi into home assistant. one thing i did notice when comparing the myenergi stats vs solarman is something odd with the battery draw.
both of these are taken at the same time and show solarman reporting 0.92kW draw from the battery with only the house connected and drawing 0.66kW. im wondering what the 0.26kW 'loss' is here..... is that the power required for the inverter/battery to run?
myenergi app is reporting 0.6kW draw from the battery...
Have moved it over here where it is probably better suited.
I don't have any Tuya devices but is Tuya local any good to you?

@graememk , to control this via HA, do you need to link via Tuya IOT platform?
Reason I'm asking: I've a bunch of Tuya wifi sockets that I used previously with SmartLife. Now, since all is in HA, to control via HA I had to have a Tuya IOT platform account, which they want to charge for... I got a 6 month grace period last time I asked, and don't want to sign for regular payment for something simple like switching on/off... If there is some other way to do this? I had tried flashing tasmota, but the machines I have don't support WiFi AP mode, and didn't manage to get it working with a usb wifi stick that supports AP mode yet...
(Mods, feel free to move this post if too much for this channel)
Thanks yea thought that might be the answer alright - would seem like there should be a hardware solution.
If you had a way of automating the physical switchover of the DC and CAN cables, yes, you could change all the Solis battery settings remotely via Modbus. Be interested to know how you'd manage the cable switchover though.
thanks The feed in priority has been great to me thanks a mill
just interested to know if you could switch between batteries- change Solis to no battery - automatic hardware switch over to battery B - select battery B in Solis (and ForceCharge/ OverDisCharge)
I had been looking previously at remotely changing the battery type to none to get surplus generation earlier on the day. That plan fell by the wayside though once I discovered the Feed In Priority mode.
What is the problem that you are trying to solve?
@Jonathan I recall you were looking at changing battery on Solis through Modbus - did you investigate this any further or any thoughts on if or how it might work. Where do you think would the physical switch over happen? at the fuse? Any idea what type of switch to use? Something that supports automation.
It's nice having the flexibility of access and still keeping the solis access for support/upgrades.
Yeah you can actually just remove the board from the wifi logger and be left with the round plug and a 4 pin plug which will do the job just as well but you can't go wrong with 13 euro for that plug :)
Happy with Solarman data logger Modbus passthough for now, but having a spare adapter might be handy for future if it ever breaks so might order one.
Someone was having issues with pulling data from one of those new solis sticks and this will be handy if you want to skip the whole Solis cloud stuff, some guy just hooked up the modbus adapter to the inverter and bringing the data directly into Home Assistant
Just bought the round adapter thingy myself, will be handy to have (but probably never use)
I joined this board to say thank you for everyone who helped put this together. I've never done python, or modbus stuff before, and I just installed HA yesterday. I am able to pull data from my inverter to HA after only a day of trial and error 😁
I am using a Megarevo 8K hybrid inverter with LSW3 stick logger that starts with 233.
I had to use the custom yaml because my registers are different than Deye and Solis. I basically just polled the ports and tried to match the results to what Solarman website was reporting, lol. Anyway, I can't find the Megarevo Modbus protocol so it'll be tough to find all the params, but I have a few key ones so far. (battery V, PV1 amps volts and power, daily use/production)
That's clever and stops arguments about hot water running out. The makers of the Eddi are shaking on their boots now :)
Latest automation, a lazy man's eddi 😆.£20.
(Don't worry it's rated for 4400w)
I have solar tubes so on the dull days we only need a little boost with the immersion.
Have it connected to HA, and set my first HA up, if tank top is less than 50c, and it's between 12 and 3pm turn in the immersion.
If tank gets to 65c, and the immersion is on, turn it off.
Generation low and had to pull a fair bit from the battery yesterday for some clothes washing, so I set about an automation to charge during my 2-5am cheap rate. At 2am it set the timed charge on, adjusted the amps to 50A, and set it to charge until the battery SOC was above 79% (i.e. hit 80%), then set amps back to 0A, and switched off the timed charge. It worked as planned and charged until about 3.15 where it hit the 80%. Well impressed! Thanks again for all the help.
Next thing on the list is figuring out how I want to determine when to fill it from the grid. I have some ideas on how but will see.
That was my thinking alright. The 5 minute polling is terrible for it. Pity I don’t have more data. Will try get more set up in case it happens again. Two neighbors have solar PV with Solis inverters also. I don’t think they were affected.
Nothing odd standing out for me on the AC side there. Frequency and voltage look within normal ranges. Maybe someone can chime in if they can spot what I'm missing.
Other possibility is that because you are only polling every 5 mins, something did occur but it is being averaged out in the graphs.
