  • Don't let the sun go down...with energy storage

    Hold onto that sunshine and use it later. We have the best storage systems for your home and business

    What is an Electrical Energy Storage Sytem?

    Used to store renewable or low-rate energy and save on your bills, there are two main types of EESS (Electrical Energy Storage System), or battery storage as most people know it

    This is a separate system, with it's own inverter and batteries, for retro-fit or storage only installs. It's on it's own circuit and monitors the grid and solar, if installed, to charge and discharge the batteries as needed

    Hybrid inverter systems have both the solar and storage connected to the same inverter. Used for retro-fit (when replacing old solar inverter) and for new solar PV systems, with batteries now or added later

    How much storage do I need?

    This will depend on your usage and requirements, but as a rule of thumb, with Solar PV, it's 1kWh to 2kWh of battery storage per kWp of solar installed. If using low-rate tariffs, then it should correspond to your usage. With arbitrage, trading energy, then more the better

    What's the best Energy Storage for me?

    There's a lot of choice out there, so we've simplified it for our customers, narrowing down the manufacturers over the years, with the best products and support. This still gives plenty of options and we trial new kit all the time

    Most storage these days is Class 1 or Class 2 category, meaning a fully enclosed inverter and battery unit, or separate inverter and battery units, respectively

    Givenergy have great value storage options with high quality kit, great app and monitoring control and also UK based support. It's flexible and modular, so capacity can be expanded

    Fox ESS is our preferred manufacturer with a product line covering wide range of AC-coupled and Hybrid units, as well a battery options. Fox is a strong pick for homeowners and small businesses looking for storage systems with generous flexibility for expansion of power capability

    SolaX offer a solid range of storage inverters, for both residential and commercial. Their products are similar to Fox ESS with less battery options

    Inverters range from 3kW to 30kW with a maximum of 4 batteries per inverter. The 5.8kWh batteries comes as a master unit with BMS (battery management system) and slave units to increase capacity as required, up to 23.2kWh. New parallel box now allows for double this capacity
