Both photovoltaic modules and batteries use direct current (DC) power. We need an inverter to change the direct current to alternating current (AC) in order to utilize the power being generated in a home. In order to maximize energy output, it is important to select an inverter with the following characteristics:
- High efficiency
- Low standby losses
- High surge capacity
- Low harmonic distortion
All grid tied inverters are pure sine (true sine) inverters, hence the grid, by nature, is a pure sine wave electricity source. The importance of pure sine wave or modified sine wave inverters may be apparent especially for off grid applications such as RV, boat or cabins. Off grid inverters are used for connecting a battery source or a solar PV system to an AC load such as a home applicance, a laptop charger, a TV.
Pure sine wave inverters are used to operate sensitive electronic devices that require high quality waveform with little harmonic distortion. In addition, they have high surge capacity which means they are able to exceed their rated wattage for a limited time. This enables power motors to start easily which can draw up to seven times their rated wattage during startup. Virtually any electronic device will operate with the output from a pure sine wave inverter.
