The 48/3000/35 MultiPlus-II GX from Victron Energy is a multifunctional inverter/charger with all the features of the Multiplus-II, including an external current sensor option which extends the PowerControl & PowerAssist functions and optimises self-consumption, but this version also includes an integrated GX device with 2x16 character display. It is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact unit. This design not only saves space, but simplifies your installation.

The clear, LCD display shows battery, inverter and (if connected) solar charge controller parameters which can also be accessed with a smartphone or other Wi-Fi enabled device.

The Multiplus-II GX is is intended for applications where additional interfacing with other products and/or remote monitoring is required, such as on-grid or off-grid Energy Storage Systems (ESS) and certain mobile applications. It has a built-in anti-islanding function and a long list of country approvals for use in ESS applications.

The built-in AC transfer switch performs the function of an Uninterruptable Power Supply (UPS) on the main AC output. In the event of a grid failure, or shore or generator power being disconnected, the inverter is automatically activated and takes over AC supply to the connected loads. This happens in less then 20 milliseconds and ensures that sensitive connected equipment continues to run without disruption. This feature can be deactivated if not required. The second/auxiliary output is live only when AC is available on the input of the Multiplus-II GX and is intended for connection to heavy consumption loads (e.g. water heater) that would quickly discharge the battery if run from the inverter.

You can achieve virtually unlimited power thanks to the Multiplus-II GX's ability to be parallel connected and setup for 3-phase operation.

Please note: Cables are not supplied. For the DC (battery) connection, Victron recommend 35mm² cable protected with a 125A mega fuse for run lengths of up to 5m. The 230V output is designed to be hard-wired to sockets or other parts of an AC system.  If in doubt with regard to specifying AC cable size and circuit protection, please consult a qualified electrician.
