Midnite Solar SMA Sunny Island Companion E-Panel


Rapid Shut down compliant E-Panel. Includes Remote trip breaker upgrade, Battery disconnect module installed and tested to work with the Birdhouse and be 690.12 compliant.

SINGLE master E-Panel in a single Sunny Island AC Coupled system. (MidNite Auotofrmer 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.
