Figures are from the manufacturers’ datasheets and are subject to change by the manufacturer. Usable energy depends on the inverter and how the system is set up. Your quote confirms the exact equipment for your home. Warranty terms are in our FAQs.

What the numbers mean

The eight terms worth knowing.

kWh and kW

Kilowatt hours are how much energy the battery holds. Kilowatts are how fast the inverter can deliver it. A 10 kWh battery with a 3.6 kW inverter can run 3.6 kW of appliances for about two and a half hours.

Usable energy

Batteries last longer if they are never fully drained, so a little is held back. Usable energy is what you get each cycle.

Cycles

One cycle is a full charge and discharge. Our batteries are rated for 8,000 or more, which is one a day for over 20 years. Capacity fades slowly with use rather than failing.

Depth of discharge

How far the battery is drained each cycle. 80% is recommended for the longest life. 90% is the most the battery management system allows.

IP65

An ingress protection rating. Sealed against dust and jets of water, so battery and inverter can be fitted outside or in a garage.

G98 and G99

The UK rules for connecting generators to the grid. G98 covers smaller systems and only needs a notification after installation. G99 needs the network operator to approve the connection first. We handle both for you.

MPPT

Maximum power point tracking: the solar inputs on the inverter. Every Juicy inverter has two, so panels can be added later without changing the inverter.

Hybrid inverter

An inverter that manages the battery, the grid and solar panels in one unit, and converts between the DC the battery stores and the AC your home uses.
