With the new generation of hybrid solar inverters, energy storage systems and battery options now on the market we put together this complete guide of what's available and how the various systems work. Since hybrid or multi-mode inverters are very similar to off-grid inverters many of these systems can be used for off-grid installations as well.
What is a hybrid solar system?
A hybrid system uses batteries to store excess solar energy much like an off-grid solar power system. For those who are not up-to-date with home battery storage systems and 'self-use' of solar energy here's an introduction to how solar works and how hybrid solar works.
With any type of solar/battery or off-grid system there are many important features to consider when selecting and sizing the various components. To make it easier we have also created the hybrid/off-grid energy storage selection guide highlighting the key features and specifications which should be considered.
Unfortunately to complicate things further there is no standard type of hybrid system available, some have integrated solar and battery storage while others can be coupled with existing grid-feed solar inverter/s to form either a AC or DC-coupled system. The different terminology used can be very confusing with terms such as hybrid battery, multi-mode or interactive inverters. To add to this some new battery systems now have built-in AC inverters referred to as AC batteries. Therefore due to the complex nature of these systems we have divided our review into four categories below:
