V-Guard DU 850 Synergy/Standard

Forget electricity woes

Solar Power systems i.e. setups made up of photovoltaic or PV modules, an inverter unit and battery, do the job of directly converting sunlight into electricity. Just like the DU 850 Synergy/Standard that reduces the amount of electricity coming from fossil fuels by supplying your operations with clean, renewable energy from the Sun. By providing more energy and lasting longer than other brands, V-Guard Solar Power Systems are the best choice for cutting your carbon footprint down to size.

The DU 850 Synergy/Standard will dramatically reduce your electricity bill and ensure that they discharge battery to the load and then charge battery again from Sun's light to be discharged further. When you invest in Solar Power Systems, you are essentially purchasing 25 to 30 years of electricity at today's prices. There are dual benefits of the V-Guard DU 850 Synergy/Standard as it can be charged through mains directly in case of bad sunlight conditions, while its in-built MPPT Solar Charger enables quick swap of energy source for just on time power savings.
