I had to completely change my cables as my first dc/dc charger was of a different type but the enclosed manual was good at explaining what goes where. Never had reboot kit before but I’d recommend it.. the Bluetooth module is helpful if you need to know the values of what battery is at what charge level. Haven’t hooked up my solar yet so can’t speak for that but I’m sure it will be problem free. ## Features - 【Multi-input for Battery Charging】Renogy DC-DC On-Board Battery Charger is designed to charge service batteries from a starting battery linked to an alternator, or by utilizing solar panels connected directly to the unit, offering multiple charging options and ensuring your battery stays fully charged.
