More info

PWM 20A charge controllers are perfect for small and medium structures, and for the controlled battery charge (electrolyte liquid or gel made). Charge controllers have a 12V or 24V voltage (auto).

Charge controllers have small display that show the status of the controller and even that of the accessories connected to it (like panels and accumulators). It also monitors the battery avoiding both overload and underload.
The controller automatically carries out these functions depending on threshold voltage: respectively HVD (High Voltage Differential) e LVD (Low Voltage Differential). 
Thanks to these functions, accumulators will be more efficient and long-lasting.

These disconnection processes, automatically carried out by the controller, are based on a parameter, the SOC (Status of Charge), which is also automatically calculated by the device.
The SOC is a very important parameter which the protections for overload and underload depend on.

Another parameter based on the SOC is the LVR (Load Voltage Regulation). Thanks to this parameter, the device knows when accumulators are loaded enough for a connection (since with the LVD protection they could be disconnected).

The electronic system is protected with a dust proof cover.
