The MNE250SMA-3PH Master E-Panel works with 2 of the MNE250SMA-Slave E-Panels to create a 3 phase system. The MNE250SMA-3PH 3 phase master includes the 3 phase 60amp input/output bypass system. This E-Panel can be used in conjunction with a Sunny Island inverter as part of a 3 phase off-grid, battery backup or AC Coupled system. Terminals are provided for hookup to leg 2 and leg 3 E-Panels. Comes with 250A battery disconnect breaker and inverter cables. Pre-wired with AC input and output wiring for leg 1 (master) inverter. (Two slaves are also required for 3 phase.)

This E-Panel does not come with a relay board, RS485 (485USPD-NR) boards or MNSPD lightning protection. RS485 boards are required when AC Coupling to SunnyBoy inverters if 3 stage charging is desired. One RS485 board goes into the master inverter and each SunnyBoy Inverter. AC Coupling to a SunnyBoy or any other grid-tie inverter is possible without RS485 boards. The Sunny Island inverter will frequency shift based on battery voltage to knock the grid-tie inverter off line. SunnyBoy inverters can switch between off-grid and grid-tie mode automatically when RS485 boards are used. To program this feature you must use either SMA service cable (USBPBS) or SMA web box (SUNNYWEBBOXU).
NOTE: A back plate (MNESMA-Short BP or MNESMA-Tall-BP) is recommended for the proper wiring alignment of the Sunny Island. - Environmental Rating - Type 1 (Indoor)
