Solar Battery Storage in Poole

Sizing a battery properly

Oversized batteries are a common and expensive mistake. We look at your actual half-hourly consumption, your array size and your tariff before recommending a capacity. For a typical Poole family home with a 4kW array, the useful window is usually a good deal smaller than the headline figures suggest.

Adding a battery to an existing array

You do not need a new solar system to add storage. An AC-coupled battery sits alongside your existing inverter and works with almost any array, while a hybrid inverter replacement can be the better option if your original inverter is nearing the end of its life anyway.

Time-of-use tariffs

If you are on a tariff with a cheap overnight rate, a battery earns its keep even in winter when generation is low — you charge at the off-peak rate and run the house from stored energy through the expensive evening peak. We set the charge windows up as part of commissioning.
