Power Backup Dual EU: Simple installation, full backup power!
The enwitec Power Backup Dual EU is an innovative grid switching box for off-grid capable battery and hybrid inverters with two AC outputs (“Grid” and “Backup”). Developed for the residential market, it offers maximum security and flexibility for your power supply.
This backup box enables all-pole disconnection of the loads from the grid and integrates customizable current monitoring to prevent overloading of the inverter relays. It can be used universally for all off-grid battery and hybrid inverters with two three-phase AC connections.
Fhat projects is Power Backup Dual EU suitable for?
The Power Backup Dual EU is ideal for residential projects that require a reliable and secure power supply in stand-alone operation. It is particularly suitable for PV systems with battery and hybrid inverters that offer a backup power of up to 30 kW.
