Description
The range runs from the 12/3000 to the 48/15000, where the first figure is the battery voltage and the second the rating in VA. With inverter, charger and transfer switch in one enclosure, the unit acts as a UPS when the grid drops. PowerControl and PowerAssist cap the current drawn from the grid or generator at up to 100 A and add battery power at peaks, so the generator or grid connection can be rated below the site’s peak demand. The IEC 62477, EN 50549-1, G99, PTPiREE and other certificates are needed to get grid connection approved. The IP22 enclosure belongs in a dry room — a plant room, utility closet or boat compartment. Several units connect in parallel for more power or form a system on 3 phases.
How to choose
Start with the battery voltage. 12 V suits the smaller units in mobile systems, while toward 15 kVA a 48 V bank keeps DC bus current four times lower. If the generator needs its own input, look at the Quattro with two AC inputs and a built-in grid/generator transfer switch. The MultiPlus-II GX saves a separate system controller, and the EasySolar-II GX also fits an MPPT 250/70 or 250/100 into the same enclosure. A three-phase site with a high-voltage battery suits the 15 kW Multi HS19 Solar 15k hybrid inverter.

FAQ
What battery voltage does the MultiPlus-II use?
12, 24 or 48 V depending on the model, shown by the first figure in the name, as in 48/15000.
Up to what current does PowerAssist work in the MultiPlus-II?
PowerControl and PowerAssist work with input current up to 100 A. The inverter takes the rest from the battery.
Does the MultiPlus-II have anti-islanding protection?
Yes, it is built in, with EN 50549-1 and G99 certificates.
Can the MultiPlus-II be used in a three-phase system?
Yes, units connect in parallel and in a 3-phase system. That is how you go beyond the 15 kVA of a single unit.
Can the MultiPlus-II be installed outdoors?
The enclosure is rated IP22, so it is mounted indoors. Outdoors it needs a protective cabinet.
