    Default Inexpensive solar reg/charger

    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 donít 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 donít want to buy the wrong one.

    A cheapy 30 - 60 A will suffice.

    Looking for recommendations.

    Thanks

    Buy quality & buy once.
    I bought a cheapy (well not so cheap, $10 less than the replacement below) for my shed, from Jaycar, to do exactly what you are trying to do, drove me crazy with constant errors, it's in the useless equipment bin now.
    In it's place is the equivalent item from Victron Energy 100/30, works perfectly.
    Will take panels up to 100V & charge/regulate a battery of 12v or 24v. Max 30A. There is also a 50A version, see both at
    I'm running a 250w 24v panel into a 12v battery.
    Or go to the next size up for future panel or battery expansion of your system.
