Manufacturer Info
The MNE250SMA-AC-SINGLE master includes the Manual input/output 60amp, 120/240vac bypass system along with separate 60amp, 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.
MNE250SMA-AC-SINGLE master E-Panel in a single Sunny Island AC Coupled system. (MidNite Autoformer and SunnyBoy inverter required)
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 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 a 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.
Requires the MidNite Autoformer MNX-240
NOTE: A back plate (MNESMA-Short BP or MNESMA-Tall-BP) is recommended for the proper wiring alignment of the Sunny Island.
