whole house SYSTEMS

If you’re intending to run your entire home off grid then the first step is to see where you can eliminate electricity use. So cooking on wood, or gas; heating water with a pellet / log boiler, range cooker, and/or solar thermal, with excess solar energy in summer being used to power an immersion heater.

You’re likely to have a fridge, freezer, washing machine, toaster and maybe an electric kettle and microwave in summer. Induction hobs are also good for sunny weather. From November – March though, we need to minimise power use unless we want to rely on backup from a generator, wind power or hydro.

We find that people frequently underestimate how much power they will need, and overestimate how much good weather they will have, so the key when designing a system is to be realistic. 

With a bigger system – and especially with BYD or  Pylontech LiFePo batteries, a Cerbo GX or Color Control GX unit is essential to manage everything properly. It enables the system to be properly configured, to control other devices – such as a generator on/off, and allows you to view and manage an internet connected unit from anywhere in the world.



Throughout the year, supplies of Pylontech batteries have been slow across Ireland and the UK, as well as most of Europe. They continue to arrive regularly but because of the backlog in orders everywhere, supplies move quickly. As of November 2021, we expect more Pylontech to arrive in with us for December / January and have a small stock of US3000C batteries currently. 
Therefore please allow up to 8 weeks for delivery for any order including Pylontech batteries.
