If you are already using a gas or diesel generator you should consider a battery and inverter subsystem. This subsystem allows you to achieve the following benefits before making a decision about PV, wind or micro hydro. AC power is available 24 hours a day with the flick of a switch. The generator can be run at convenient times for direct AC power and battery charging. Generator operation is more efficient.
Energy costs are lower because generator run time is reduced.
Generator capacity is better utilized as a result of battery storage. The inverter is a basic component of any independent power system that requires AC power. Inverters convert DC power stored in batteries into AC power to run conventional appliances. Popular items run from an inverter include computers, entertainment systems, power tools and kitchen appliances. Just over a decade ago inverters were so inefficient and unreliable, many people restricted themselves to 12 volt lights and appliances.
