Enphase Micro Inverters - Wiring

#1

Post by vantech2022 »

Hi,

I am planning a new install and will be using enphase inverters. I am questioning the wiring diagram, which is not overly useful.

Can the inverters be wired in a parallel arrangement or do they need to be wired in series?

Parallel:

Breaker > junction box >
output 1 = panels 1-3
output 2 = panels 4-6

Series:

Breaker > junction box > panels 1-6

Just wanted to clarify this.

Thanks.

They are wired in parallel, as each has a 230V AC mains connection. They have a "loop in, loop out" topology, so the mains side connects from one microinverter to the next, avoiding the need to run separate mains cables from each microinverter back to the connection point.
25 off 250W Perlight solar panels, installed 2014, with a 6kW PowerOne inverter, about 6,000kWh/year generated
6 off Pylontech US3000C batteries, with a Sofar ME3000SP inverter
