Agree with you 100% on Jeff Motes videos. I wish I knew enough about electricity to label it genius because that is what it appear to be. I think he has it licked.Had already purchased the spf 5000 es (2) from AliExpress when I found out about the USA version. Had so much trouble getting the supplies I ordered and found out there are people there that are less than honest…. Especially, selling the infamous Lifepo4 batteries. Doubted access to warranty work, so as seen on YouTube, I went inside mine and removed the bonding (N to Ground) and after putting some good pressure on the contact around the hole discovered it is effective to do this…..no continuity at all. I have ditched the auto transformer, as unsafe, and went with an isolation transformer, that will feed isolated offgrid loads, and mini split ac’s! Jeff Motes, is I believe, an electrical engineer and a electrical Contractor who illuminated my mind on the subject. He has an awesome YouTube channel!
Does anyone here know of a source for the main boards in these Spf 5000 es?
Difference between what you have and US version is the silicon on the back of the contact screw to ensure no electrical contact.
As far as buying boards, sometimes we have to just admit we messed up and charge it off. For you to rebuy US version or just put silicon over back of screw contact. Maybe Signature Solar would help on technical details on how.
