Victron Energy MultiPlus-II battery inverter-charger

Victron Energy MultiPlus-II battery inverter-charger comes with a stylish steel enclosure and is particularly suitable for large-scale storage projects.

The MultiPlus-II 48/3000/35-32 230V complies with the Australian Standard for grid-connected inverters (AS 4777) and is certified in an increasing number of other countries.

The redesign of the company’s flagship inverter-charger is aimed to meet new demands in the market. As well as a new look and a flatter form factor, the MultiPlus-II has redesigned its proven electronics to take advantage of miniaturisation while complying with emerging energy industry standards such as a built-in double-relay to enable ‘anti-islanding’ for safe interaction with energy grids.

The MultiPlus-II is a 48 V inverter-charger that readily connects with a wide range of energy storage systems, from lead-acid and lithium-based batteries to zinc-bromine flow batteries. The unit is easier to install than earlier models with AC connections accessible via a single plate on its base. The 18 kg MultiPlus-II draws 11 W of standby power, less than half that used by the model it supersedes.

As with all Victron inverter-chargers, the MultiPlus-II is a transformer-based system, which can immediately deliver backup power if the grid drops out, including start-up supply for high-demand devices such as air conditioners and freezers.

The battery inverter-charger has optional internet-enabled remote monitoring, both through a secure Victron portal or authenticated third-party applications. This remote monitoring enables the 24/7 performance logging of connected batteries.
