Hi,

Just looking into solarizing the 12v side of my shack.

I have a few older solar panels, 37v.

I see that chargers can be either 18v for a 12v off grid system or 36v for a 24v system.

I don’t want to run 24v batteries and then have to reg down to 12v so I am looking for a solar charger that will take my 37v (36v) panels and allow direct charging to 12v batteries.

I have been looking at the various MPPT charges on eBay but just get confused with specs and don’t want to buy the wrong one.

A cheapy 30 - 60 A will suffice.

Looking for recommendations.

Thanks
