2012 Latest design!Cheap Solar Controller With Led indicators,20A PWM solar Charge Controller CM2024,12/24V Auto work Solar Panel Charge Regulator Controllers
1. Intuitionistic LED indicators show the current system battery capacity, charging and discharging state of the battery.
2. Having the protection functions as overcharging, over discharging, overload, short-circuit and reversed connection.
3. Tandem type PWM charging makes the charging efficiency increase by 3% to 6%, compared with non-PWM charging.
4. The parameters of charging and discharging have been set during the production (special parameters need to be told in advance), so no need to adjust the parameters.
5. It can set the working mode of the load.
6. USB charging function (optional).
7. Grid-complementary (optional function)
8. Remote telecommunications function equipped (optional function).
9. Prevent battery from discharging to battery at night.
III.LED indicators instruction

voltage drop of discharging circuit
1. This controller can only be used to control the charging from solar panels to lead-acid battery. It can not be used to control other generating appliances to charge the battery.
2. The controller is equipped with solar panels and battery reversed connection function. But it does not have load reversed
connection function. We will not afford free service or compensation for the damage caused by load reversed connection.
