A standard inverter (also known as a string-inverter or central inverter) is a standalone box that is typically installed close to your fuse box and electricity meter. There is typically only one, or possibly two, string inverters on each residential solar installation.
Central inverters are very similar string inverters but are capable of handling a larger number of strings. These inverters are normally used in commercial installation around Australia, instead of the strings running directly into the inverter as is done in the string type inverter, a combiner box is used before the inverter where the various strings are connected and then the DC power is sent to the inverter, where it is converted to AC power.
Micro-inverters are small inverters that are fixed right behind each solar module. they convert the DC power received from each of the modules into AC power directly, which is then combined to house power and supplied to the power grid.
Hybrid inverter is a combination of traditional on-grid inverter and off-gird inverters. During normal operation the hybrid inverter synchronizes with your mains utility power and supplements your power usage using the solar power during the day. In addition to this cost saving during daylight hours, batteries are used to supplement your usage during the evening hours.
Hybrid inverter with backup battery and emergency power supply
In addition to Hybrid inverter these inverters have an Emergency Power Supply (EPS) which offers backup power if your mains utility power fails. In EPS mode power is supplied solely from the battery pack up to the maximum capacity of the inverter installed.
