Solar Invertors

Types of Solar Inverters Perth

Inverters are one of the main components in a solar system installation. An inverter takes the raw DC power from the solar panels and converts it to the Ac power used in our homes. There are a few different types of inverter.

 

String invertors

These are the least expensive type of invertor, and were the most common option for many years. You only need one string invertor for a solar power system. They take the total DC power from all the solar panels and convert it to 240 Volt AC power. They use high DC voltages, and produce High AC voltage, so should only installed by electricians/engineers.

A String invertor will be a large box, usually mounted inside the home.

Microinvertors

Microinverters work on the same principle as other inverters, but there is a single inverter for each panel rather than one large inverter for the combined panels. With these systems there should be a microinverter installed on the back of each panel.

An advantage of microinverters is that each panel functions independantly with its own inverter. So if one panel is under shade and producing less energy it won’t compromise the performance of the other panels.

microinverters effectively pass AC straight from the panel, so there is no DC cableing through the house.

You can get perhaps 12% energy out of a microinverter system over the course of a year, as it helps compensate for less than ideal situations.

Optimiser Based Systems

This use a combination of both string and micro inverter systems. There is an individual optimizer on each solar panel, and a larger string inverter on the inside of the house.

for situation where there is a lot of shading over the panels, where the conditions change through the course of the day, this optimised system will give the greatest amount of power possible. But for most homes the excess cost of this type of system is not needed.

Solar System Installation

‌The right solar power system will provide free ongoing energy for your home. Australia is fortunate in having weather condition that work well for solar energy.
