Battery
batteries are used to store energy. They can be made of various materials however lead acid batteries are most commonly used for solar & wind applications. Lead-acid battery recycling is one of the most successful recycling programs in the world. The modern lead acid battery was developed in 1859 by French physicist Gaston Plant

Charge Controller / Regulator
these devices are primarily designed to prevent the batteries being overcharged, however the more advanced units also offer a variety of information such as charging current, battery voltage and some even log historical performance data.

DC to AC Power Inverter
these devices convert DC power as stored in batteries into AC power as found in a house. They are very convenient, however they do waste power when on standby and as such are not recommended for lighting, refrigeration or other applications where the inverter is on for longer periods of time.

DC to DC Converter
these devices convert a dc voltage supply into another dc voltage, such as a 24v to 12v converter. They are generally more efficient than using AC inverters, especially for devices such as laptops or mobile phones.

Low Voltage Disconnect
LVD these devices disconnect a load from the batteries to prevent over discharge of a battery. Over discharge is one of the most common ways of killing a battery and an LVD unit is essential on most power systems.

Maximum Power Point Tracking
MPPT a technology used in newer charge controllers which allows more power to reach the batteries. This is achieved with a very high efficiency dc to dc converter

Mounting Frame
used to mount solar pv modules. They can range from being a simple supporting framework, through to a fully automated tracking structure which follows the sun.

Solar PV
photovoltaic solar panels which produce electricity when exposed to light. Also called pv modules, pv cells and solar modules. The "pv" effect was first discovered in 1838 by nineteen-year-old Edmund Becquerel.

Wind Turbine Generator
'WTG' a rotating machine which produces energy from the wind. The first known electricity generating windmill operated was a battery charging machine installed in 1887 by Professor James Blyth in Scotland.
