I have a Quattro 5 kva inverter charger on my boat. It’s setup with a Northern Lights generator as one AC power source and shore power as the other.
This has worked well for 2+ years. We used shore power all winter living aboard in a marina. We hadn’t used the generator yet this sailing seasons and when we revved it up we found that, while it provides AC power to match any active AC loads, it no longer charges the (Victron LifePo) batteries.
The light comes on to say it’s bulk charging but it’s not.
I didn't make any intentional changes to any settings. I turned off the Quattro a few weeks ago to let a workmen get safely into our mechanical space.
The Quattro came back on afterwards and had been happily inverting like always. Just no charging.
I’ve tried turning it off and on again. No luck.
Any ideas for a setting that could have changed during a firmware update or something along those lines?
