RE: 24 VOLT SOLAR BATTERY BANK - How To Wire It Up - Wiring Charts Included

in #dtube7 years ago

Yes, 48 is better and more efficient that 24. Most homes with large systems are 48 because of this fact...but it cost a lot more usually in buying a battery bank that large. 16 batteries or more for the maximum effectiveness.

Sort:  

As you might recall I'm currently remodeling an old (1972) houseboat. I intend for it to be a 'bug out boat'....a 'homestead of last resort'...as such it'll have as many solar panels (flexible) and batteries as I can afford. Electricly powered propulsion of course.

As such...this kinda thing is VERY interesting to me. When it comes time to buy batteries and such...I might actually have a clue.

Yeah, go with the AGM's, I can speak from experience that they have no maintenance issues. DON'T BUY THEM FROM A RETAILER...they will charge you a lot of money. Check out AGM options online like ebay with good reviews. These Vmax batteries had excellent reviews and were a lot cheaper than others I found through dealers.

I had AGM (or at least sealed and maint. free,) on my truck. It carried 4. I tried Gel and that was an expensive flop.

I'd rather go with a higher energy density than lead acid (AGM is that too)...I've been reading about several new technologies that are 'any day now'...zinc/air for example.

Supposed to be much lighter, much cheaper and much more powerful.
