Unleash the Potential of Hybrid Energy Storage

A Hybrid Energy Storage System (Hybrid ESS) lets you capture solar power from dawn to dusk and store surplus energy for use any time during the day. This system includes a versatile hybrid inverter, compatible with both Low Voltage (LV) and High Voltage (HV) batteries, and you can choose to add optional solar panels.

Maximise Your Solar Energy

With the Hybrid ESS, the process starts with your solar panels, which feed power into the hybrid inverter and then into your chosen LV or HV battery. When the battery is full, any extra power is transferred through a smart meter to the national grid. This clever arrangement means you keep some electricity back, ready to power your home on cloudy days, at night, or during a power cut.

Selecting Your Ideal Hybrid ESS

The first step in choosing the right Hybrid ESS is to select a hybrid inverter with the correct capacity, measured in kW, to match the peak AC power demand of your property, garden office, shed or garage.

Next, choose the power of your solar panel array by calculating the DC to AC ratio. For instance, matching a 6kW DC solar panel array with a 5kW AC-rated inverter gives a DC/AC ratio of 1.2 (6 kW / 5 kW = 1.2), which usually minimises losses since solar panels typically produce over 90% of their rated power for most of the daylight hours. A ratio of 1.25, however, can improve the economics of the setup, particularly if the project's scale is limited by the AC capacity. We suggest aiming for a solar panel array with a DC/AC ratio of about 1.25, but we are here to help if you need advice on different options.

Finally, work out the capacity of your battery bank in kWh by calculating the kW power demand during the longest night hours in your area. Once you know this, choosing the number of batteries to match this capacity is straightforward.

Note: when installing energy storage systems to supply residential premises, the installer must follow important safety guidance here.
