E-Panel for SMA Sunny Island inverter
The master includes the input/output bypass system along with separate 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 250 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 MNSMARB is included to disconnect the MNX-240 Autoformer during normal operation. No idle power is consumed by the Autoformer in normal operation. The backed up critical loads panel always has 120/240 available. 60A is available on leg 1 & and 30A on leg 2 in the critical loads panel. Comes standard with one MNSPD-300.
A brighter future. Off the grid. Iron Edison battery systems can be used for 12, 24 and 48 volt applications. We can also help you optimize battery capacity to take better advantage of the solar, wind and other hardware you may already have in place.
