Go outside. Pick up a rock. Stare at it. It is smarter than a smart converter.you want ti run your generator 12-hours a day and charge batteries to 80% get a "smart" charger. Your batteries will be sulfated at the end of the first season. Expensive chargers like the Boondocker are less offensive to flooded batteries but there isn't a "smart" charger on the face of the earth that can maintain an off-grid battery bank without damaging it. Yes you can push boost buttons a dozen times and it will help but I thought you might like to hunt, not screw around with batteries. Start generator. Occasionally glance at ammeter. When amperage drops to 12.0 or less shut off generator. But I guess you have money to burn. Oh well...
