(y) I don't have a heat pump, but have been using their emonPi for monitoring our house, solar and battery usage for 2 years - works really well and highly configurable. The team know their stuff, are responsive, and have been putting in a lot of effort in the heat-pump monitoring for a while.

Who is 'we' ?

You can't store power (Watts), you can only store energy (Watt-hours or kWh). To work out how many batteries you need, you will need to calculate how much energy you need to store to use as power later. That will be measured in kWh. From knowing that, you can then calculate the capacity of...

(y) I installed my ground mounts in the heatwave summer of 2022 and grass growth was no problem at all then, nor last summer. But this year though, it's kept raining all spring and I've had to strim (*) the darn grass so often. Just happy I can charge up the strimmer's batteries for free...

You forgot to deploy the chainsaw first ;) They look pretty grounded to me :) Seriously though... looking good - those mounting frames look nice and solid - what are they?

Doh... Why does that not surprise me :mad:. Sounds like the exact same issue that @radiomean had 2 years ago. https://diysolarforum.com/threads/ct-inaccuracies.45436/post-580015 Fingers crossed and keep us updated.

Sure... try typing in "ICHEATMAY24" ;)

TADTS! Seriously though... for a grid-tied system I would expect a bit of meandering around 0W as the inverter tries to keep the import/export balanced, but certainly not a constant draw of 50 to 100W. From what you are saying, it sounds as though the Growatt thinks it is balanced (as...

Do you know what options are available with the new S6 Solis range? I have an S5-EH1P and for that you could use the user-defined option in the Solis and basic SMA protocol on the JK (if it supports such). I'm not aware of other users on here having the S6-EH1P yet (they are not yet approved...

When I was considering Deye/Sunsynk I thought there is also an option to use an Eastron power meter and just have the Deye/Sunsynk use the power data from the Easton sent over an RS485 data link, rather than have a directly connected CT. If that is an option with your Deye, then it could be...

(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 ;)
