10amp Charge Controllers – PWM and MPPT
When you are building a small system the 10amp Charge Controller is a good option for you. Most small systems will work very well with the PWM but you should also look at the MPPT.
MPPT & PWM
When selecting a 10a Charge Controller, always consider a 20a or 30a as in the future you may want to build a bigger system. Did you know? A Solar Charge Controller also stops reverse current at night Because at night without a Charge Controller is is possible dc current will flow back to the Solar Panel and effectively attempt to charge the Solar Panel with dc voltage.
