Standard deep cycle 12 volt 105 amp hour batteries typically for small installations. We would normally use 2 or 4 of them maximum, for a small cottage that just has lights and a camping fridge. These batteries have a lifespan of between 2 – 5 years.

Charge Controllers

We only use maximum power point tracker (MPPT) regulators in our household installations. These microprocessor controlled units can extract up to 30% more power from your panels, and extend the lifespan of your batteries by charging them correctly.
