Solar Charger Question for Generator Starter Battery?

Since you are plugging into your house, I assume this is a portable generator. If it is a standby permanently installed genset with modern computer controls you will have a vampire drain on the battery. If it is a portable, probably no vampire drain. I got a 10watt solar charger without a charge controller,for my F250 and it keeps the battery charged. I wish I would have gotten a 20 watt solar charger with mppt controller to keep a constant battery voltage. With the present 10w solar charger my battery stays about 12.0 volts in the winter. Standby generator battery voltage should float about 13.3v.
