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.


As of mid July there is a shortage of Pylontech batteries across Ireland / UK. We have been given a date of the end of August for availability, so until then any system containing Pylontech batteries is on backorder only and cannot be fulfilled until we take delivery of more batteries. However we are now able to offer an alternative in the form of BYD lithium batteries which are also certified for use with Victron systems and which offer even better cycle life than Pylontech.
