Hopefully, I'll be testing it tonight myself. Assuming I can connect my Pi Zero to the inverter. I assume the cable you are referring to is the cable that actually came with the Growatt unit for connecting it to a PC?
Correct, thats the cable. DO post back with a report.
Ok, so the initial setup was insanely easy, very much plug and play ... the web-based interface is good.
Thanks for the info ... I am assuming that that will indeed work for me too ... I fear though, that when I change my current broker designation, I will then lose 'access' to the information that I currently receive from the DIYBMS v4 I am also running (and would not use the same broker/IP address that the solar assist does).
I'm pretty new to MQTT so not sure myself ... I'm sure it's a pretty common thing but I, for the life of me, cannot seem to find the easy and/or simple answer/solution.
Beat me to it!
Where did you get your wire trays? I cannot find any other than alibaba?
PV Keeper works great with Growatt if you right click the icon for it and tell it to run as administrator. It will stop misbehaving.
Many, including myself have tried that, it only helps a little. It still crashes. Crashes happen during peroids of peak battery charging, it never crashes during the night or other than peak charging. Growatt confirmed this and sent me a updated version to try but I had already switched to Solar Assistant which is vastly superior so I never tried the new revision.
Noticed "battery emulator" is spot on, re-adjusted it the other day by using 2 tabs, 1 with Configuration and the other with Dashboard-Battery, ie - you can watch the soc change right after changing settings then click re-connect and you will see Soc update in real time, used the voltages from Gyll batteries and after a day or 2 it is within a couple of percent of all 3 types of Lifepo4 battery types I have.
That is interesting. Pierre sent me a email about the new release, told me battery SOC was changed to work better with non-lithium batteries which it does, its far far better now. I didn't realize he also tweaked it for lithium users, I have 340ah of AGM in my setup. I did tweak the settings as you did to dial it in closer and now have it where its extremely close.
Yep, wish for Battery Voltage on dash board, just run Home Assistant that shows everything now except "pv current" is only 1/2 the current, no entity that shows mppt 1 and 2 combined, o well very happy w/SA and HA integration, also see Est Sol Tot is a add on to HA that predicts today's solar production based on your system, - pretty close - most days, don't expect 19kwh today, batteries will get full and shut down solar, Joe.
