PWM Solar Controller 12V/24V Auto ID 10A 20A 30A Solar PV Panel Controller Controller 
 
Product Description: 
Controller for 12V/24V automatic identification intelligent controller, maximum working current 10A version, using 12V battery, solar panels can be no-load voltage in 15-25V, power in 120W within the solar photovoltaic panels, using 24V battery, can be no-load voltage in 30-50V, power in 240W within the solar photovoltaic panels. 
 
Controller for 12V/24V automatic identification intelligent controller, maximum operating current 20A version, using 12V battery can be no-load voltage in 15-25V, power within 240W solar PV panels, using 24V battery can be no-load voltage in 30-50V, power within 480W solar PV panels. 
 
The controller is 12V/24V automatic identification intelligent controller, maximum working current 30A version, using 12V battery can be no-load voltage in 15-25V, power in 360W within the solar photovoltaic panels, using 24V battery can be no-load voltage in 30-50V, power in 720W within the solar photovoltaic panels. 
 
This controller can be used at home or for street light control system. That is, built-in light control system. 
Warm tips: the inverter can only be connected to the battery, can not be connected to the controller. 
 
 
Attention: 
Solar panel power and battery capacity as far as possible to match, to prevent the battery capacity is too small, and the solar panel power is too large, the battery can not deposit all the electricity issued by the solar panel and protection, resulting in charging anomalies, the battery charging current of 10% of the battery capacity, try not to exceed 20%, for example, 60AH battery charging current is 60AH divided by 10 = 6A, the charging current can not be more than 12A, the current charging easily shorten the life of the battery or the big The charging current is easy to shorten the service life of the battery or damage the battery, in addition, this controller is designed with a high current charging protection function, when the battery charging current is too large, the battery can not accept all the electricity issued by the solar panels when the system will protect.
