Shop for the right solar battery technology for your backup or off-grid renewable system

Boost efficiency of your PV System

Solar batteries are the beating heart of every off-grid solar power system

The solar panels generate the electricity from the Sun, as efficient as possible; but it’s the rechargeable solar battery (or set of batteries) that provide the consistency needed for comfortable off-grid living around the clock. Battery technology has come a long way, and the solar batteries that are the most used today are deep cycle Absorbed Glass Mat (AGM) batteries and Lithium Iron Phosphate (LiFePO4) batteries for their ability to handle long, frequent, deep charge/discharge cycles. These batteries can also be used in other renewable energy applications like wind and hydro power systems as well.

Absorbed Glass Mat (AGM) batteries

AGM batteries differ from flooded lead–acid batteries in that the electrolyte are held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase the surface area enough to hold a sufficient amount of electrolyte on the cells for their lifetime. The fibers that compose the fine glass mat do not absorb and are not affected by the acidic electrolyte. These mats are wrung out 2–5% after being soaked in acids just prior to finish manufacturing. AGM cells are leak-proof due to the captive electrolyte and do not need much ventilation under normal conditions, this feature makes them very reliable solar battery banks.


AGM Batteries are non-hazardous, lightweight, resistant to cold temperature, not inclined to heat up (low internal resistance) and able to hold a static charge for a long time

Lithium Iron Phosphate (LiFePO4)

Deep cycle lithium batteries are helping to revolutionize the battery industry. These batteries do not use traditional lead-acid battery technology to carry an electrical charge. The batteries move lithium ions from the anode to the cathode during discharge. The ions are transferred back when charging.

The design is more durable and lighter weight. A deep cycle lithium battery can weigh up to 80% less than a comparable lead-acid battery. It is also more resistant to vibration and shock.


The typical lithium battery can recharge at up to four times the speed of a standard deep-cycle lead-acid battery.
