Volt Polska PWM solar panel charge controller 20A 2x USB

Solar Charge Controller PWM 20A 2xUSB is designed to control the operation of autonomous photovoltaic systems . The device provides the right charging current characteristics for the battery(s) and protects them from over-discharge or overcharging. SOL PWM solar controllers can be equipped with a solar battery and a 12 or 24 V battery.

Key features:

Automatic detection of 12/24V input voltage
12/24 VDC/24 VDC/24 VDC with easy-to-read LCD display and interface buttons for control
Efficient 3-phase PWM charging ( pulse width modulation )
Battery charge level control with memory night reset option (application e.g. for street lighting)
Protection against overload, short circuit, overvoltage, undervoltage, battery overcharge/discharge, reverse polarity
Built-in 2 USB ports
