Hi Team, I have been reading over the forums, and it has answered many questions, but also raised a few questions.
I have ordered two Victron DC-DC converter, but am now questioning if I have ordered the correct ones.
Converter 1 - Victron DC-DC 12/12 30Amp - Non-isolated
I plan to put this in my boat to use the starter/alternator to charge my 120Ah Lithium battery. I will add more Lithium's over time.
My boat motor is a Honda 60 outboard. The specs say it produces a charge current of up to 17Amps. Therefore do I need to scale my converter back to a 12/12-18Amp which seems to be the smallest smart converter? This is an isolated converter, but I know from this forum that I should use a single negative/ground.
Converter 2 - Victron DC-DC 24/12-30Amp - Non-isolated
This converter is to go into my Kart racing trailer.
I have two separate battery banks in my trailer. I have two 24V Lithium batteries in parallel that are charged from solar and the grid or a generator (if required). These run everything, both AC and DC.
I have a separate 12V 130ah deep cycle flooded battery that only runs my caravan movers on the trailer. That way, at the end of a long race weekend, when the lithium's are down, I still have power to move my trailer (oh, and the caravan movers are 12V's, and use too many amps to get the 24V's down to 12V's).
Again, is the 30Amp converter too big, or will it work OK? Also, is it fine to share the negative/ground across 24V's and 12V's, or should I get an isolated converter in this case and keep the negatives separate? The price difference is minimal.
Any help would be appreciated. thanks in advance.
