Backup controller 3PN-35A Fronius 4,240,048,CK

The Backup controller 3PN-35A 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.

Fronius has been designing and building in Austria since 1992: its PV range is known for active cooling, modular boards and a widely used in-warranty replacement service.

Key strengths

Essential loads kept aliveSeparates the part of the installation that must stay in service without the grid.
Automatic switchingThe changeover between grid and island operation happens with no manual action.
Ready-made wiringA pre-wired box: less installation time and fewer mistakes.
System componentDesigned by the manufacturer for the inverters of the same range.
