The MultiPlus-II has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). 
It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters. For examples and more detailed information see the ESS (Energy Storage System) manual.
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
Monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, via the required Color Control GX or Venus GX, from adjusting your Multi to auto starting a back generator and more...

What Victron MPPT solar charger should I use with this inverter?
Hi Washington. The MPPT type and size is not related to the inverter, but rather to the number and size of the solar panels required.
The Multiplus 2 states 48V DC. Given a 48V DC battery system and coupling to solar PV in grid parallel format, What Mppt controller can be used? Does it need to be one with 48V out or can two 24V ones be coupled in series to give 48V.? Thanks
Hi William - the MPPT output needs to match the battery voltage, so it must be 48Vdc
