Epsolar ViewStar VS4548BN PWM – 45A-12V/24V/48V Charge Controller

The ViewStar Series solar controller is designed for off-grid solar systems, such as street lights, solar home systems or other small loads. It has LCD display, reliable battery charging, full electronic protection, and programmable parameters.

The controller adopts advanced digital control technology, LCD display, and automatical operation. With the features of Pulse Width Modulation (PWM) battery charging and unique control technology, the controller will improve the long battery life efficiently.

The controller could charge the battery and discharge automatically for off-grid photovoltaic (PV) systems. The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and extensive electronic protection can prevent damage against incorrect wiring or system faults.
