is a 2V 300Ah deep cycle sealed lead-carbon battery to provide 14.4kWh maximum capacity at 48V at the 10 hour discharge rate.

This can be supplied in:

• a 12V bank of 6 batteries, ideal for small huts, sheds, pump stations
• a 24V bank of 12 batteries, e.g. for tiny houses
• a 48V bank of 24 batteries, e.g for medium-sized off-grid houses.

All batteries come with cables, and the 48V bank can be supplied with a steel rack.

These are valve regulated sealed batteries and so do not require maintenance such as topping up with water. They can also be mounted in any position unlike flooded lead-acid batteries.

To take full advantage of these batteries and to ensure a long service life your solar system must be sized correctly: e.g. for a 48V set of these batteries you should have at least 2200W of panels. This 48V set is suitable for a smaller off-grid house or shed. For a larger house we have Narada 2V REXC-600 batteries giving 28kWh at 48V.

We can also supply Narada racking systems for this battery, available here.
