Yes, but a special backup unit is required. The EnergyHub is powered by alternating current and will shut down when the power goes out. By supplementing the system with a backup, the battery and solar panels can be kept running and supply important loads with electricity.
Ferroamp today offers Ferroamp EmergencyPower 1P, which is a single-phase inverter of 2 kW. The product includes an automatic backup power switch that switches selected loads between mains and backup power operation. With Ferroamp EmergencyPower 1P, the power of a battery can be used for the most important loads of the property for a long time.
The solution can be used for Ferroamp systems with only one EnergyHub unit (EnergyHub Wall 14/21/28) and at least one battery with ESO unit and DC-fed BMS. The solution has not been tested for systems with multiple EnergyHub units or in PowerShare networks.
The Ferroamp EmergencyPower 1P can drive all single-phase loads up to a rated power of 2 kW. However, some loads with high starting currents can cause the overcurrent protection to trip and the system will need to be manually restarted. Ferroamp EmergencyPower 1P does not support three-phase loads.
The product has an innovative function for its own earthing during backup power operation that can be installed at a significantly lower cost than a conventional earth.
The product is connected to a phase on the building’s power grid, to DC distribution or PowerCase in the Ferroamp system and to the selected single-phase loads to be provided with backup. The product has an IP21 protection rating and is intended for installation indoors. For more info on installation, see the installation manual.
NOTE
Only trained electricians may install Ferroamp products.
The product can be set to three different modes:
OFF – The selected loads are turned off and backup power operation is disabled
BYPASS – The selected loads are supplied only from external power grids, no backup power operation
AUTO – Selected loads are automatically switched between grid operation and backup power operation
The product also has a function for Blackstart. The system energizes and starts ESO and SSO followed by the connection of loads. Note that blackstart only works with up to five DC nodes (SSO, ESO) connected to the system.
A light indication on the product shows the current operating status. Values in Ferroamp’s portal or app are not updated during backup power operation because the EnergyHub is then turned off.
To protect the battery during backup power operation, Ferroamp EmergencyPower 1P shuts off battery discharge if the SOC reaches 5%. When the sun comes out, the system can be turned on with the black start button so that the battery can start charging again.
Reserve capacity for backup operation by setting the lower limit of the SOC value in the EnergyCloud web portal to the minimum level you want to reserve for backup operation.
The product is manufactured in Sweden and supplied by Ferroamp’s partner Safevolt AB. Support and warranty are provided by Safevolt AB at info@safevolt.se.
