It has been a breeze working with the SustainPower team. Now when the lights go out, the generator turns them on automatically. It’s made a huge difference to our ability to operate without interruptions.

Steven Hackner, General Manager, The Test Kitchen

Thank you for an amazing service. The generator was installed in a very professional and neat way. The best thing,… it really works. No more worries about load-shedding!

What is a battery backup system and how does it work?

A battery backup solution is an electrical modular system composed of an inverter, one or more battery modules and logger device for remote access and monitoring. When the grid power supply is available, the batteries will be charged via the inverter.

Should a power failure occur, the inverter will automatically switch over and supplies your home or business with the energy stored in the batteries. The switchover happens within split seconds without any human intervention. Once the grid power supply comes back on, the batteries will return to charging mode, ready for the next cycle.
