Which battery group is best to use to start the generator? Engine batteries? House batteries?
Issue #1: House batteries are used for 2000 Watt Inverter. Generator will not start when house batteries are at 10 volt cutoff to the inverter.
Issue #2: House batteries are being replaced and I wonder if it would not be best to move the generator start cables to the engine batteries, OR install a separate battery for starting the Onan generator and provide a charging wire from the engine alternator?
When the generator is powering the Xantrex Inverter/Charger, the house batteries would be re-charging.
I believe the house batteries are preferred and if they go dead your battery boost sw. can be used to start the genset. Also starting the main engine should charge the house batteries pretty quickly.
