How to select a solar charge controller for your PV system
What a solar charge controller does. Think of a solar charge controller as a regulator. It delivers power from the PV array to system loads and the battery bank. When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off.
The 10 Best Solar Charge Controllers (+ How to Choose One)
A solar charge controller with an LVD (low voltage disconnect) output feature is a suitable option if you''re powering small appliances, like lights. Solar charge controllers with LVD automatically turn off the connected device when the load drains the battery bank to a low voltage.
MPPT vs PWM Solar Charge Controller: What''s the Difference?
A PWM (Pulse Width Modulation) solar charge controller is a linear regulator that uses a series of ON and OFF pulses to control the amount of current flowing into the battery. The length (or duty cycle) of these pulses is varied according to the battery''s voltage. ... Good for Small Solar Systems. PWM controllers are also a good choice if …
