The first step is to figure out the voltage of your phases. The voltages for the 208 vac rated microinverters should be within the following ranges.
Enphase Appnote Networking Manual Manualzz
Enphase 3 phase wiring diagram. That being said there is a wide range of different motors and what you have on hand can be completely different. A three phase motor must be wired based on the diagram on the faceplate. Smart solar clean energy for everyone. This means that youll need two branch circuits for this 725kw sample system. Make sure to measure the line to line and the line to neutral voltage of all service entrance conductors prior to installing any solar equipment. Continuing the example from above the maximum number of iq 7 single phase 230vac microinverters that can be installed on a 20a circuit is 13.
Iq micros on a three phase system iq micros connect line to line with each microinverter branch circuit connecting into a two pole 20a circuit breaker. Enphase q relay installation guide three phase learn how to install the three phase enphase q relay galvanic disconnection device. In the united states for low voltage motors below 600v you can expect either 230v or 460v. Balanced three phase generation is achieved by connecting the same number of microinverters between phase pairs l1 l2 l2 l3 and l1 l3 with three two pole circuits into a three phase. 8 7 6 5 4 3 1 8 7 6 5 4 3 2 1 d c field wiring diagram 208 vac three phase important.
