My 12v 3000w inverter went out. I decided to upgrade to two EG4 LL 48v 100ah batteries with the EG4 3000 charge Inverter and plan on charging my Leaf from it. (That’s why I went so big). A few issues I’m having and any suggestions greatly appreciated.
The charge inverter requires 45v to activate charging. My 4-100 watt solar panels went from parallel to series to get the higher volts no problem.
But my renogy 50amp dc to dc charger has a max of 14volts. That’s my issue.
Currently thinking of leaving my 12v battery bank in charge it from the alternator. Use the 48volt batteries for all AC items. So two battery banks. 48 volt charged from Solar for AC side. 12volt for the DC side.
I would like however to use the DC to DC charger to charge the 48 volt batteries also.
I was looking at a step up. 12 volt to 48 volt. Only 6amp. Not sure if the amps are enough? Probably run from 12volt side into the EG4 3000 watt charge inverter. Not really sure?
Any suggestions greatly appreciated.
Thank you
