MNE250SMA-AC-SINGLE master E-Panel in a single Sunny Island AC Coupled system. MidNite Autoformer MNX-240 and SunnyBoy inverter required. A back plate (MNESMA-Short BP or MNESMA-Tall-BP) is recommended for the proper wiring alignment of the Sunny Island. The master includes the input/output 60amp, 120/240vac bypass system along with separate 60 amp, 120/240vac AC input and output breakers. This E-Panel can be used in conjunction with a Sunny Island inverter as part of an AC Coupled system. Comes with a 250amp battery disconnect breaker and inverter cables. Pre-wired with AC input and output wiring.

RS485 boards are required when AC Coupling to SunnyBoy inverters if 3 stage charging is desired. One RS485 board goes into the Sunny Island inverter and each SunnyBoy Inverter. AC Coupling to the SunnyBoy grid-tie inverter is possible without RS485 boards. The Sunny Island grid-tie inverter will frequently shift based on battery voltage to knock the grid-tie inverter offline. 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 an SMA service cable (USBPBS) or SMA web box (SUNNYWEBBOXU).

The backed up critical loads panel always has 120/240vac available. 60amps is available on leg 1 and 30amps on leg 2 in the critical loads panel. Comes standard with one MNSPD-300.

Variations

• MNE250SMA-AC-SINGLE
  
• MNE250SMA-AC-SINGLE-E
  The MNE250SMA-AC-SINGLE-E is our Export version. It is the same E-Panel but with the proper color wires and proper breakers for a 230v 50hz inverter.
