FAQ: How does the EMF-1 wattmeter show power supply to the grid?
The usage of is very simple. The wattmeter will show the power supplied to the grid the same way, as it shows the consumption from the grid. There is no “plus” or “minus” sign. The wattmeter shows only the actual value, no matt
Question: Can the micro-inverter (in the GridFree installation) work in an island mode against some sine wave DC/AC generator? (e.g. in parallel with my own independent 230V island system)?
Answer:No, the microinverter in most cases will not work with in such mode. There a

Harvesting the additional energy from the solar panels
Using more solar panels in parallel with one micro-inverter provides additional power. With the price of solar panels dropping, it seems feasible to have more panels per single inverter.
From the graphs you can learn about the example of the extra energy in
Multiple solar panels connected to single micro inverter
The graphs are showing the energy yields from multiple solar panels connected to single micro-inverter with a 230Watt rating. The graphs show results from a 250Wp panel, a 290Wp panel and two 250Wp panels in parallel making an equivalent of a 500Wp solar
