Residential Electricity Backup System
System Designed for use with Enphase IQ6 and IQ7 Microinverters
Although we strongly recommend the use of Enphase IQ8 in backup systems, we acknowledge that Enphase IQ8 is not available yet and that it might be important for some customer to move forward with their backup requirements urgently.
The following two systems are designed using an off-the-shelf grid-forming inverter that when combined with SimplBox and Enphase IQ6/IQ7 microinverters would provide excellent back up solutions.
The two approaches depicted below are differentiated by the size of the solar system. For small to medium-sized solar systems of less than 7.5 kW, the first solution works well. When the size of the solar system is larger, we recommend the second solution.
