$begingroup$ Well, I want to use this in my car, to protect the main starter battery from being discharged below 12.5V by a second - deep cycle AGM battery which is charged off the main battery. That second battery can pull 70A of current, but that will happen only sometimes, when the alternator + main battery are actually able to deliver 70A.
A 48 V system can provide more power, improve energy recuperation, and allow up to an 85% decrease in cable mass. 12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures. ( See the article on electrical injury.)
It did say 480v input, is that for solar and battery input? When i was looking i saw a Victron, that said 480 input, but i could not tell if that was solar string voltage or battery input
