I have an enphase solar system with iq7 micro inverters. I also have a 15KWh battery bank that I want to add as a back up and have the battery power the house at night when it isn''t producing solar. My main confusion is how to charge the batteries from solar when the grid is down. The envoy/iq system shuts down if the grid is down.

Grid inverters need to intercept a frequency of 95~96.5% efficiency to initiate operation. In Europe, the required frequency is 50Hz. Micro inverters operate within this range, while string inverters are now reaching up to 97.5% efficiency. However, dirty panels in a single string can affect the entire system.
When the current is less than or equal to that of the micro inverter at 60Hz, there is no longer a level of resistance for the micro inverter to sample at a rate greater than its output. Therefore, it no longer produces power to cause islanding. The voltage doesn't matter.
