Looking for a DC-only genset, to be used for charging battery banks only, supplementing solar. Not interested in AC usage at all, want to maximize efficiency, so avoiding inverter-based charging.
Would prefer an off-the-shelf unit with direct drive, but otherwise perhaps the power head is just HO automotive alternators?
Ideally low-rpm heavy-duty engine designed for quiet and long-term reliability like the old Listers, but smaller and lighter for mobile use.
If the engine can't be robust at a reasonable cost/weight, it must be capable of being made quiet.
Any suggestions welcome.
