PWM Solar Charge Controller Description

pwm solar controller led and key description

Indicator lamps

Solar Access LED Indicator light is on when solar energy is detected and no solar energy is detected.
Battery LED The indicator light is on after connecting the battery, the indicator light will flash with 0.5 seconds switching frequency when the load is protected by long time voltage, and the indicator light will light up normally after the voltage rises to the restored value.
Load and WIFI LEDs Indicator light is on when the load is turned on, off when the load is turned off, after turning on the WIFI, the indicator light will blink 5 times at a frequency of 0.5 seconds, then return to the load indication state for 10 seconds, and then return to the WIFI indication state again.
