RENEWABLE ENERGY BATTERIES

BATTERIES FOR SOLAR AND WIND POWER SYSTEMS

FROM ROLLS, VICTRON, SONNENSCHEIN AND MASTERVOLT

We offer a range of batteries from leading manufacturers including:
ROLLS, VICTRON AND SONNENSCHEIN.  Please refer to the full list below.

Batteries are a key component in solar and wind powered energy systems.  The can be used as the main source of power in stand-alone energy systems or providing backup power in grid connected systems when the electricity supply fails.

Batteries require proper maintenance and can fail prematurely if not well looked after.  Deciding on the "best" battery for your requirements requires careful consideration.  The most important aspect of buying any battery is its DEPTH OF CHARGING CYCLE.

There are SHALLOW CYCLE and DEEP CYCLE batteries.

SHALLOW CYCLE BATTERIES are typically Car batteries. These batteries give high currents for short periods of time, for example, when starting your car. However, they cannot withstand repeated deep discharging - below 20% - and therefore are not suitable for use with solar pv systems.

DEEP CYCLE BATTERIES are designed to be repeatedly charged and discharged by as much as 80%. Having said that, if these batteries are shallow cycled - not discharged below 50% of capacity - then they will have a very long life.

A typical Lead Acid battery contains liquid acid in cells that are NOT SEALED. They can be prone to leaks. AGM and GEL batteries are known as SEALED Lead Acid batteries. Thus, both AGM and GEL batteries are virtually maintenance free.

All our batteries are branded and direct from leading manufacturers.

The size of a battery bank is determined by the storage capacity required. Battery capacity is determined by the amount of electrical energy the battery can deliver over a certain period of time and is measured in Ampere hours (Ah) when discharged at a uniform rate over a given period of time.
