What are Hybrid and Battery Inverters?

Written by Infinite Energy

hybrid and battery inverters

In order to purchase a solar battery storage system for your home, or add a battery to your existing solar system, you’ll need a hybrid inverter. You also have the option to install a separate battery inverter alongside your string inverter, like SMA Sunny Boy Storage, which combined perform the same functions as a hybrid inverter.

Like a standard solar inverter, a hybrid inverter converts the DC power your solar system generates into AC power, which can be fed directly into the grid, or used to power your home appliances.

Unlike a standard solar inverter, a hybrid inverter can also send excess DC power to be stored in your battery. It can then draw on and convert this into AC power to supply the appliances in your home when required. This usually happens at night time, when your solar system is not producing any electricity.

At Infinite Energy, we stock hybrid inverters from Fronius and SolarEdge, plus battery inverters from SMA.

 

Fronius

Fronius currently stock the Symo Hybrid Inverter, which is suitable for three-phase homes only.

To add the StorEdge Hybrid Inverter to systems with a SolarEdge three phase inverter, or a non-SolarEdge single or three phase inverter; the StorEdge AC Coupled Inverter may be used.

 

SMA

SMA currently offer Sunny Boy Storage and Sunny Island 3.0M / 4.4M Battery Inverters for domestic use. Unlike Hybrid Inverters, Battery Inverters are added and work alongside your standard solar inverter. This makes SMA a great choice for retrofit battery installations.
