Application:

Applicable to small-size solar off-grid systems,

Characteristics:

· 12/24V automatic recognition

· Efficient tandem PWM charging mode prolongs the service life of batteries, and improves the system performance;

· Power MOSFET is used as electronic switch, without any mechanical switch.

· Adopting temperature compensation and automatic adjustment of charge and discharge parameter improves the service life of the batteries.

· Controller is provided with the automatic protection functions for overtemperature, overcharge, overdischarge, overload and short-circuit.

· Automatic protection function for incorrect connection of any combined photocells and batteries.
