Why choose a Powervault 3 for your battery storage?
The Powervault 3 is compatible with all solar PV systems and lets you use more of your solar generation when you need it. It's not limited to just daylight hours, saving you more on your energy bills. It comes with a hybrid solar inverter, ready for action when your old one fails, saving you the replacement cost of that too.
If you're on a time-of-use tariff, such as Economy 7, you could save even more on your bills by charging on cheap overnight electricity. And the easy-to-use customer portal gives you full visibility of how much you’re saving on a day-by-day basis.
Which package is right for me?
We offer the Powervault 3 with and without the EDF Energy grid services.
Right now, when the electricity grid runs short of capacity during peak periods, extra power can be generated but usually not in the cleanest or greenest way. Conversely, when there's excess renewable generation, demand can't be increased, which leads to wasted energy.
This is why we're building a network of small-scale batteries to help balance the peaks and troughs of energy production and customer demand for energy. In return for helping balance the grid for ten years, we’re offering a substantial upfront discount off the retail price of the battery.
You can also purchase Powervault 3 at full retail price and opt out of the grid services.
