Volt Polska Solar controller

The SOL PWM 20A 2xUSB solar controller is designed to manage the operation of autonomous photovoltaic systems. This device ensures the correct charging current characteristics for batteries and protects them against deep discharge or overcharging. SOL-PWM solar controllers are suitable for installations with a solar panel and 12 or 24 V batteries, automatically recognizing the input voltage value. It features a clear LCD display and interface, controlled via two buttons on the housing. The controller utilizes efficient 3-phase PWM (pulse width modulation) charging and allows for battery charge status monitoring, with the option to reset the memory at night (e.g., for street lighting). It includes protections against overload, short circuit, overvoltage, undervoltage, battery overcharge/discharge, and reverse polarity. Additionally, it has two integrated USB ports.
