Solar inverters

Buying a inverter is an important step, there are various types of inverters, and a range of power outputs.
Then the the required connection type and your allowed or permitted type. not only this but non grid forming and parallel inverters.
Inverters can be a stand alone unit, which just converts DC to AC or can be a AIO – all in one – that has a battery charger (CC) and MPPT CC which controls the solar.

Grid tied inverters.

Grid tied inverters work in parallel with the grid, as do hybrid. they need to be on the ENA register to be legally installed. Many inverters available are NOT on the ena register can Cannot be legally installed. This includes used older inverter that may have been legal to install. The current requirement is G99, G98 and G100.
Grid tied, tend to not have batteries, there fore send any unused power to the grid, in the same parallel hybrid inverters, but have a battery.

Hybrid inverters.

A hybrid inverter is a device that can combine different sources of power, such as solar panels, batteries, and the grid, into a single system. It can convert DC electricity from solar panels into AC electricity for use in the home or business, and also manage the charging and discharging of batteries.

Grid Attached inverters.

Grid Attached inverters, are inverters like a hybrid but, they do not return or work in parallel with the grid and continue to work when the grid goes down. The grid attachment can be used to charge the battery or as a pass though for higher loads. These also can be used for backup ( UPS) functionality for your whole home.

Off grid inverters

Off grid inverters work without a grid connection, they may have a generator connection to support charging or pass though power, but will have solar and battery to provide power. typically this type of inverter can NOT be attached to the grid and cause a trip due to the inverter not having a earth bond connection relay detachment.

Parallel inverters.

Inverters of various types can work in parallel. but most will not. grid forming and grid parallel are two different formats which can cause serious problems if mixed or paired wrongly. there are inverters that can work together called Parallel, this is typical for off grid or grid attached installations where you may have more than one inverter, upgrade to two, or have a standby. some grid tied hybrids will also work with other types of inverters.

Stand alone inverters

Stand alone inverters are just inverters, they produce power from DC, They connection to the battery and produce 230v AC power. They come in various power outputs but in different wave forms. The wave form is the power ( see image). what you use can work on some items, but not on others, it is best to have a pure sine inverter.
