Solar PV Battery Back Up!

Our newest product on offer is the latest innovation for both businesses and homeowners alike, Solar PV Battery Back Up.

These fantastic systems can be retro-fitted to an existing Solar PV system or fitted alongside a new installation, and will store unused electricity generated by the PV system in a battery bank. You can then use this stored power first in the evening and in a power cut you can then draw power from the battery bank to continue supplying power to your property!

Contact us today to talk to one of the team about adding this invaluable system to your property.
