DC generator to charge my RV house batteries?

You will need to configure the MPPT controller to work with a Wind Turbine. That changes in interernal IV curve to work with copper windings and not PV panels.. Not all MPPT controllers are adaptable.
What's the 36V amperage ? Age of the engine? sometimes lightly loaded diesels will Wet Stack and get gummed up under light loads

You do not need any charger or MPPT if the genny has a 36 volt DC output. Only real issue is 36 volts DC is a bit to low to charger with on a genny, and no charge or controller is going to fix that, just make it worse and take longer. Besides a MPPT controller would not work.

Hello Everyone,

I am installing solar and upgraded house batteries in my RV. I will have a 24v - 370A/H battery bank and need backup charging for times when solar production is not adequate.

I have come across a diesel 36v generator. Basically a small diesel motor with a 36 volt alternator.

What I am considering is using the 36 VDC generator to feed a 40A MPPT charge controller to charge my 24v battery bank.

My RV is diesel and I don't want to have to carry gasoline. Otherwise I would buy a little Honda inverter generator.

What do you all think of this plan? Suggestions?

Thanks.
