Main features and advantages

 

 

 

High reliability: when the temperature of the battery module is 70 degrees, the controller will operate at rated power, which is more reliable than the controller installed in the side box. Very low internal resistance, no need to be evaluated.

 

For outdoor use: ETL has been approved and does not need to install the controller in the box. The surface of the product is rough surface treatment, protection grade IP65, shell material anti ultraviolet, epoxy seal printed circuit board, and connection box connection with battery board waterproof treatment.

 

Increase battery life: continuous PWM3 stage charging mode: charging, PWM voltage charging regulation and floating charging. When the temperature sensor is used, the controller and the battery can be selected one by one for temperature compensation.

 

Rated for hazardous locations: This product is a charge controller specially designed for industrial solar systems such as oil / gas, which is audited through Class1, Division2, GroupsA, B, C, D.

 

Other instructions: the state display LED lamp is installed on the controller, making it easier for people to read the controller working behind the battery panel assembly. It shows that the charging and charging regulation of solar modules and the condition or malfunction of the system usually work at night.

 

Installation is convenient: installed on the 1/2 inch battery assembly junction box outlet (PG13.5, M20), fast installation with the lock nut, the distinguished wire can be quickly connected to the terminal of the battery board component junction box.
