If the boat is insured or is going to leave US waters and hopes to be insured, better CYA it and check this out. NMEA may be of help also. https://www.nmea.org/content/STANDARDS/nmea_2000_certified_products
We did Marine electronics on the side and cruised our sailboat for a decade. It was great until we lost insurance and then learned to live with it. It got good again. Same thing now with offgrid and wildfires. Whatever I get into ends up with loss of insurance. Good Luck !

The electric motor is meant to run on nine 12V batteries, or 108V. The motor manufacturer recommends a charger that can run on 120V or 240V. But has anyone seen a charger that can take solar power and directly charge a battery bank of 108V? The alternative that I see here is to have two separate battery banks, one for the motor, and one for house loads. Then we would have the solar charge a 48V battery bank, and then use an inverter to charge the 108V battery bank. It seems inefficient, although that may be the only choice. A separate but related question: what is special about a marine inverter? If there is a 5kw charger for the battery bank, we will need a large inverter to handle this plus other AC loads, and I am not sure if there are "marine" inverters this large. And so other than concerns about getting wet, is there harm to putting a Radian, or a Sol-Ark on a boat? Cheers, Dave -- [3] Dave Tedeyan, P.E.
