Deep Cycle Solar Batteries
The battery is the heart of any off-grid power system. Treat them well and they will reward you with a long life.
Lead acid batteries have dominated the off-grid market for many years, mainly due to cost, predictable performance and high reliability. However, new Lead Carbon technologies offer the promise of higher cycle life and less sulphation.
Lithium-based batteries are becoming more affordable, although the high cost per kWh is only justified in specialised applications, where weight and space is critical, and sub-zero temperatures are unlikely.
Large lead-acid battery banks are assembled from multiple 2V cells wired in series, each of which can be rated up to 3900Ah. Generally, 2V cells have the longest life, due to their tubular plate construction. The next best option is to choose a 6V block, which tend to have a longer life than most 12V batteries.
Gel or AGM batteries are more resistant to deep discharges, as well as being sealed and maintenance free. This makes them more suited to remote sites and safer to handle.
