Frequently Asked Questions

MultiPlus-II 48/3000 or 48/5000: which do I need?

The 48/3000 gives 3,000VA output with a 35A charger. The 48/5000 gives 5,000VA with a 70A charger. Choose the 3000 for smaller off-grid and backup systems. Choose the 5000 if you are running heavier loads or want faster battery recharging from shore or generator.

What does 35-50 mean on a MultiPlus?

In Victron's naming, the first figure is the battery charger output in amps and the second is the maximum AC input current the unit can pass through. So 48/3000/35-50 is a 48V unit, 3,000VA inverter, 35A charger, 50A AC transfer.

Is the MultiPlus-II 48/3000 UL 1741 certified?

Yes, this version is UL 1741 listed, which is the standard for grid-interactive inverters in North America. That matters if your system will interconnect with the utility, since UL 1741 is typically what an inspector and utility require for grid-tied equipment.

Does the 48/3000 work with BigBattery lithium?

Yes. Victron MultiPlus-II units support CAN and RS485 communication with battery management systems, and BigBattery lists the 48V HUSKY 2 INV as compatible with Victron MultiPlus-II 3000 and 5000 systems.

What is the difference between UL 1741 and UL 458 versions?

UL 1741 covers grid-interactive inverters for stationary and utility-connected use. UL 458 covers inverters in mobile and RV applications. Choose the certification that matches your install, since it is what determines code compliance and inspection sign-off.
