Can I use a power source other than a PV panel to charge my batteries?
We do not recommend using a DC power supply with any of our controllers. While they appear to be similar to PV modules in function, DC power supplies have considerably more output capacitance. Connecting a DC power supply to our controllers may cause excessive heating and premature failure. AC powered battery chargers are a better alternative for systems requiring AC battery charging
This controller can also be used with almost any DC source, such as a power supply or higher voltage battery bank, where the max voltage is between 16 and 75 volts. It has built in current limiting*, so may be used to step down a 24 to 60 volt battery system to a 12 volt auxiliary battery for accessories. It is commonly used in tel-com sites to keep a smaller 12 volt battery system charged from a 24 or 36 volt system.
