(y) yes, I use SOC, temp and voltage as inputs to the charge current. LOL... yes... been there, done that... 2A doesn't work! Interesting... maybe that is firmware-related though :unsure:. Our Solis has been switching between 99% and 100% SOC every 30 mins or so, all afternoon.

Welcome!.. the more we know, we know that there is more to know ;) You got the answer from the Solis+Pylontech expert on here, but do shout if you have any other Solis-related queries - there are a few of us regulars on here who have Solis inverters.

Just an idea for your code when you add the temp monitors... What I did with my code (which, as you know, was originally derived from yours) was to adjust the charge rate so it is not just based on SOC, but also dynamically based on temperature, in line with the datasheet for my EVE LF280K's...

Unlikely. As @hwy17 said. Most AC to low voltage DC power supplies are doubly-insulated switch mode PSU's that don't even have an earth connection on the AC side.

Now... why didn't I think of that ;)

Unistrut?

Hmmm... maybe assuming they don't get too hot :unsure:🚒 Wondering if a resistor in series with the CT could have similar effect?

I just had another thought... Is the CT sensitivity configurable at all? I know you can double the output of a CT by looping the wire through it twice, but am wondering if it is possible to halve the sensitivity? If so, then maybe (and this is a quick guess, haven't had time to think it...

Just trying to get my head around installing HA on a Raspberry Pi 5 running Raspbian. The HA guides recommend completely imaging the RPi with the HA 'specific purpose OS'. Is it not possible to just run HA as a stand-alone application alongside other stuff? Anyone done this? Have RPi 5...

I can't see how that would work :unsure: So, let's assume the house usage is 2000W and your panels are producing 1000W. The first SPA will see from the grid CT an import of 1000W. It will start discharging at 1000W to get the grid CT to zero Watts. As it starts discharging, the second SPA...

Yes, my Overkill branded JBD uses 2 parallel 8awg wires. Following the thread I linked to in post #2 I monitored the temperature of the wires - they rarely get above 35C, which surprised me.

Yes, but just don't staple those wires to some cheap plywood :eek:

That is a pain for us DIYers :( Assume you can't downgrade the firmware on your Growatt to revert to a version that does support third party batteries? What is initially strange is that AFAIAA Fogstar use Pace BMS which supports Pylontech protocol and you say Growatt support Pylontech too -...

(y) yes, mine did.

Not sure about Growatt, but IMHO with my Solis, the internal feedback loop will do whatever is possible to get the grid CT value down to zero. So, unless the firmware is designed for parallel operation they will always fight each other. The fix, if the Growatts use an RS485-based power meter...
