Sun Energise20W 12V Solar Battery Charger & Maintainer, Waterproof 20 Watt 12 Volt Solar Panel Trickle Charger Kit, Built-in Intelligent MPPT Charge Controller for Car Boat Marine RV Trailer Truck

Q: Have two batteries in my boat, can I use solar charger for both

Thanks for your interest in our solar boat battery charger. Yes, you can use solar charger for both two batteries in your boat. The solar charger was desinged to cahrge 12V battery, so, if your 2 batteries are 6V, make sure they are in series; if the 2 batteries are 12V, make sure they are in parallel.

Q: for a minimal use auto will this unit gain back power lost in batt to start auto in a 1 or 2 hr time frame.

While the Solar battery charger isn't designed or promoted as a fast charging unit, nevertheless, I would think it bring the battery up enough to provide the power needed to start a car. I use my charger to "top off" any power loss that might occur even with constant and frequent usage. If the electrolyte in each cell of your battery is up to capacity, then the Solar Charger should charge your battery sufficiently after one or two hours. If the battery cells are low of electrolyte, then the cells should be topped of with distilled water and then begin charging. Otherwise, any effort to charge a battery that is low on electrolyte will be a waste of time.

Q: Can I keep this permanently connected to my car battery even while driving? If not what else do I need?

I would not leave this connected when driving as the vehicle charging system *may* feed back into the regulator system of the solar panel. Just remove it when you are operating your vehicle on a regular basis and re-install when you are leaving your vehicle in long term storage.

Q: Can I use 1 solar panel and 1 to 3 wire splitter to maintain 3 battery banks?

Thank you for your support to our solar battery maintainer. The 12volt solar battery charger waterproof was desinged to charge 12V battery, so if the 2 batteries are 12V, make sure they are in parallel. And we also suggest that one solar trickle charger for one 12volt battery.
