I purchased a Growatt 3000W model. I connected two 12V 200AH batteries in parallel and the AC input. I connected the AC input to the house and turned the unit on. The screen remains blank and there is no response in any way, fans nothing. Do I have a bad unit? I would expect it to turn on if it’s connected to the main.
Does the battery need to be charged to turn on the unit? Should I charge the battery independently first?
Thanks for the support.
