Hi,
I have 230v (EU) Multiplus 3000 installed in my RV with a 6.75kwh lifepo4 battery using a REC-BMS Active BMS
The RV has a 5500kva Onan generator with an auto switchover when the generator is started.
When I installed, the Multiplus would work fine on either grid or genny power, but now it will not switch thru the genny power. ( I haven't used it on generator for about 7 months)
It makes a click/clunk sound like it's trying to switch it thru but that's followed by another similar sound (to me it sounds like a relay connecting then disconnecting)
The genny is a 60hz (US made) but as I said, it's never been a problem and the auto switchover is working as the 110v parts of the RV (roof aircons an some sockets) are working fine and if I look on my Cerbo gx, the Multiplus is seeing the genny power (as per the attached screenshot) but it doesn't pass the power through or charge the battery.
I've power cycled everything in the system and that didn't work.
Any suggestions most welcome
