Saurya Solar Hybrid PCU

Saurya Solar Hybrid PCU (OFF GRID)

Saurya Solar Inverter is a Hybrid PWM based PCU which has Dual Source of Charging, from Solar as well as Grid Power. Solar Charge Controller is designed for maximum utilization of Solar Power with optimum Battery charging and timely shut down of Battery at lower Voltage. It gives a Pure Sine Wave with minimum Distortion.

circuit cuts off the operation, which is indicated by glowing of a Yellow LED on top. The Operation resumes after the input voltage is corrected. The Design of this relay is micro controller based which drives the Relay at the output having a mechanical life of 1 million Cycles.

KEY FEATURES

Dual source of charging from Solar Power as well as Grid Power.
