Hybrid inverters vs Solar only inverters

What are the differences, in regard to the role they play in a energy market ?

There are ‘Solar-specific’ inverters and ‘Hybrid’ (bi-directional, multi-powered) inverters.

Solar Only inverters are designed to Only works with Solar DC energy, and commonly only one AC input power source!

Hybrid inverters on the other hand are bi-directional and give the option to manage power from several sources, like Solar, Wind, Aqua (DC) input as well as having the choice to use power from a Generator and finally allow State Grid power (AC) to be connected if required.

Hybrid inverters are now the standard purchase choice, even if Battery's are not yet integrated.

So, if/when you decide to install batteries it is a simple plug & play install.

Where a Gen-Set is used to Blackout-proof a premises, the Automatic Generator Start (AGS) function in most Hybrid inverters, will start & stop the generator if the State Grid goes down, if you have batteries installed, commonly the Generator would only need to be used after extended periods of bad weather, and as all power from Gen-Set is sent directly into a Hybrid inverter, it performs two functions, firstly it power your premises and at the same time the excess energy Charges your batteries, that is a double win situation, as usually a generator will only needs operated for short periods, as our Hybrid inverters utilise the built-in Charge Control circuit that can be programmed to float or rapidly charge the Batteries to a pre-set level, then the Generator will automatically be switch off, once the Battery bank reaches the pre-set level you set.

So, if you already have a Solar Array and looking to upgrade your power independence by adding Battery storage, "Solar Only inverters" are fairly useless, unless you purchase additional equipment like AC Converter, whilst you can install separate standalone equipment like BMS (battery management system), MPPT (maximum power point tracking) and possibly an Automatic Generator Starter (AGS), it is obviously better & simpler to install a Hybrid inverter with all those features incorporated, rather than purchasing several separated items, each drawing additional power !

After many years of the deceptively named "electricity retailers" over-charging, the storing of solar & other energy like Wind etc. in batteries, is rapidly becoming mainstream, largely due to the low cost of Solar & Battery Storage technology evolving to become almost a self funded investment!

Every home that has battery storage will need a Hybrid inverter to first convert solar energy straight to 240v, with excess power being automatically sent to the battery's, then after sun set the stored energy is converted back into 240V AC electricity as needed.

If you are going to purchase Batteries, we strongly recommend you purchase the largest Battery bank your budget/finances can afford, as an Inverter is the heart of a micro grid, that simply converts your DC voltage into 240V, in either single or three phase, remembering it is simpler to add additional Solar panels to increase your harvesting anytime in the future.

Without a doubt Battery's are the Foundation stone of any independent power system, allowing you to create the best self sufficient Micro-Power-Grid possible!

NB: We recommend a 3kW be the smallest inverter to purchase or higher, as that will cover most residential energy demands, in Australia a 5kW inverter is commonly the maximum size allowed when exporting into the state grid for a feed-in rebate, unless authorised by your local distribution company.
