Grid-tied battery backup system:
Provides security during a power outage
What we’ve accomplished:
The goal of this project was to cut electricity costs and also create seamless backup power for security against power outages.
We installed a 6.12 KW Solarworld (USA) Grid-Tied Battery Backup PV System and 30 Evacuated Tube Domestic Hot Water System in order to create the best system possible to achieve the project goal.
