Grid box three-phase for grid-connected systems connection up to 138kW SMA GRID-BOX-12.3-20
The Grid box three-phase for grid-connected systems connection up to 138kW is the component that manages emergency operation and separation from the grid: it keeps the essential loads supplied when the grid is down and brings the system back in parallel when it returns.
Using the manufacturer's original part avoids compatibility problems at commissioning and keeps the warranty on the unit it belongs to valid. The code in the table is the manufacturer's catalogue code — worth checking before you order.
SMA Solar Technology is the German manufacturer that set many of the standards for PV inverters: conservative electronics, mature firmware and a service network across Europe.
