Package including:

1. 1pcs 30A solar controller
2. 1pcs user manual english

ViewStar solar charge controller that adopts the most advanced digital technique, displays on the LCD and operates fully automatically. The Pulse Width Modulation (PWM) battery charging and the unique control technology can greatly increase the lifetime of battery.

The controller is for off-grid solar system, and protects the battery from being over charged by the solar module and over discharged by the loads. The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.

Application:

Ideal for medium off-grid solar system with LCD display.
