Vispra Sun 3 Kva Solar PCU Price Specifications

Vispra solar energy pvt ltd is a Startup recognized in leading Solar Off-Grid MPPT PCU manufacturer making India self-sufficient on solar energy. We use advanced MPPT technology in our Solar Off-Grid PCU that can simultaneously run the load and charge the battery. Suitable for standard Lead-Acid Batteries, as well as Flooded, Sealed and SMF type. Our Solar Off-Grid MPPT PCU stand apart from the rest because of their high-quality design and multiple features we have packed into it to make your life easier.

The MPPT uses much more advanced technology than PWM charger and meant to extract maximum power from the Solar Panel to provide optimum charging current for the battery. It gives 40% more power output than conventional PCUs. Vispra solar Off-Grid MPPT PCU is superb for installation in petrol pumps, gas stations, schools, commercial, and residential applications.

Solar Inverter Hybrid Mode

With both mains power present and solar present (power Save mode) Battery Fully charged Automatic Change over to Backup mode and runs on Solar, if solar not sufficient excess is taken from the battery until battery discharge below 11.95v.
Battery discharge below 11.95 volts Returns to mains utility power and charges the battery using only solar. When again

the battery is fully charged – repeats above function.

With Mains power present and Solar Absent Returns to mains utility power and charges battery using Mains utility power

Solar Charger

Solar Prefer mode (with mode Switch TOP) Only charges through solar when solar present, if Solar absent then charges through Utility power (charging LED glow continuous)
Dual Mode (with mode switch Down) Charges both from Mains utility power and Solar (charging LED blink)

LED Display
