Good morning,
I am looking for some guidance in setting up my new Growatt model SPF 3000TL LVM-24P connected to a 24 volt 3kwh powerwall from Big Battery. Both units unfortunately sat in a Detroit warehouse for almost a year until I could find a broker to get them across the border for me to use at my cabin in Northern Ontario, Canada.
They both looked in very good shape with no damage to the boxes or units. The LiFePO4 batteries were extremely low charged and I’ve charged them for apporox 4 days in mixed sun conditions using 24volt configured solar panels. They are up to 26+ volts dropping overnight to around 23.5 volts. When I connect the Growatt inverter to the battery after disconnecting it from the charging panels around 25-27 volts the Growatt will still not turn on.(no noise or LED lights) I’ve mostly followed Will Prowse set up/guidance along with the Growatt manual and have verified repeatedly all wiring configuration to be correct. Also I have disconnected the ribbon on the BMS for 30 seconds to try and reset any issues (suggested by big battery) but still do not getting any led/start up when i turn on the Growatt unit. Is there a main fuse or internal breaker that could have been triggered?? Is there anyway I can verify the Growatt unit is functioning aside from connecting to the battery?? I have reached out and called and emailed growatt america with no response from them (now a week), Any help would be greatly appreciated… Have a great day.
