With the optional Backup Box STB5K connected into the Sungrow Hybrid inverter [INV-SG-SH5K], the system is capable of operating as an off-grid system to ensure an emergency power supply for emergency loads in the event of a grid interruption or blackout.
Features an external button to switch a system from on-grid to off-grid. The Backup Box does not include the battery.
