Grid Connect with Battery Backup Power

Backup Power during Grid Failures

Storm coming in, red clouds

Did you know that your grid feed system disconnects from the grid during blackouts? In this case it does not produce any more electricity - neither for grid feeding nor for the supply of your house.

Australia's ageing electricity grid with its above ground power lines will always be prone to failures - storm damage being the most common cause. A Grid-Feed Backup System supplies your house with power in the case of a blackout.

If you own a Latronics PV Edge 1200 or any SMA inverter you can upgrade your grid feed systems with backup power. Utilise your solar power when you need it the most - during blackouts.

We can upgrade your Latronics inverter with a basic backup system. You will need a 48V battery bank and regulator, an automatic transfer switch and another inverter to supply your selected powerpoints with 240 volts.

SMA inverters can be upgraded with a more sophisticated 'Sunny Backup-System' and automatic switchbox, which integrates your solar array before using up power from your batteries. You can also incorporate an AC generator.

System Examples

We have compiled three system examples with prices for the major components. Please note that in most cases installation cost would be substantial as your house's powerpoints must be separated for crucial and non-crucial equipment. Cost for installation is not reflected in the prices shown.
