Enphase IQ8M Micro-inverter

The Enphase IQ8M microinverter is fully equipped for a smart grid. The IQ8M therefore meets the requirements of complex power grids with regard to voltage management and frequency decoupling. The Enphase IQ8M can be remotely updated through the Envoy S to meet the requirements of grid developments. Monitoring per panel is no problem at all with the Envoy S Metered monitoring module.

The beauty of these micro-inverters is that they are software-prepared for island operation. Note that to make this work properly and safely, you need the IQ system controller.

The Enphase IQ8M inverters are extra fire-safe because they carry much lower voltages, and are equipped with a rapid shutdown system via the necessary Q relay.

The Enphase IQ8M microinverter has a maximum output current of 330Watt at peak times. You can connect up to 480 Watt peak to it without any problems, but then the number of generated watts above 330 will be capped.

Suitable for solar panels with 60 (or 120 half) and 72 (or 144 half) cells.

Note! A maximum of a 16 amp group may be placed on a 25 amp grid connection (1/3 selectivity). These micro-inverters produce 1.43 amps each. A maximum of 11 solar panels may therefore be placed on the 16 amp group. For a slightly larger system, two cables must be drawn to the meter box, each with its own fuse. The maximum amperage that can be placed on a 40 ampere main fuse is 25 ampere, so that is about a maximum of 17 panels on this main fuse. If you have a 3×25 ampere mains connection, you can therefore connect a maximum of 3×16 is 51 solar panels, which is equivalent to an inverter power of 16830 watts.

If you make a string, make sure with your design that you prefer not to put more than 8 panels in a row one after the other, because of the monitoring that can then falter a bit. Rather, make T-splits and more strings to minimise data flow.

The IQ8 cannot be combined with the IQ7 series. The IQ8 must be fitted with an Envoy-S Standard or Envoy-S Metered gateway.

Note! Warranty on these inverters only applies if an Envoy and relay are connected to them!
