Here is how I have my system setup:
-2 - 48v Growatts in split phase. Utility is in its own breaker panel and not connected directly to the house. Utility is set up to only power the washer and dryer and nothing else. The Growatt units run into my main breaker panel and powers the whole house. Utility only comes in on the back end when there isn't enough solar or battery power.
-I have 14 commercial 460w Jinko solar panels which provide me with more then enough power to run my whole house all day long.
-I just added 2-24v 5kWh total batteries which are in series to provide 48v.
SO my system is set in SBU mode and during the day solar provides power to my house. After sunset the batteries kick in and that's were my problems start. I plan to add more batteries soon but for now the 2 - 24v ones are all I have
I originally had 8 Harbor Freight AGM 12v 35ah batteries setup to provide 48v (left over from a small 12v system I had) and these would provide me with 1 hour of power before the Growatt would recharge then back to battery for an hour then recharge and so on.
I bought the 2- 24v LifePo4 batteries from Battery Evo and was excited to get better batteries and longer usage during the night. Talking to battery Evo and giving them my info on my nightly energy use I was told that I should get about 2.5 hours out of the battery which is cool that's what I was hoping for and if I add 2 more sets then I would be good for the whole night.
Here is my problem...I connected my batteries and waited for night to come. Sun went down and I watched as the Growatt switched over to battery then 3 min in it switched to utility and started to charge my batteries...then back to batteries once they were charged then 3 min later back to utility and so on.
Between me, battery Evo and 1 email reply from Growatt we can not figure out what is going on. This expensive battery gives my only 3 min of use so I figure its a setting problem someplace but I just don't know where to look anymore.
I came across this forum and seen everyone talking about these units and how everyone was trying to really help each other so I had to sigh up in 1 last effort to try and figure this out.
Here are my current settings:
#1 SBU
#2 20a
#3 APL
#5 USE
#12 48v
#13 55v
#19 56v
#20 56v
#21 45v
Thank you in advance
