MultiPlus — inverter/charger 500 VA – 5 kVA (and 48 V 20 kW)
Country: Netherlands · Model: MultiPlus
The MultiPlus inverter/charger is built from 500 VA to 5 kVA, plus a 48 V model rated 20 kW. When the grid drops, the load moves to the inverter in under 20 ms, the same way a UPS works. It goes into off-grid and backup power systems, boats and motorhomes.

Description
This is the classic series, combining a sine wave inverter and a battery charger in one enclosure. While grid or generator power is present, the unit charges the battery and passes power through to the load. When the input fails, the internal relay opens and the inverter picks up the load, so computers and controls ride through the outage. Up to 6 units run in parallel, and the same units can form a 3-phase system. The MultiPlus works with lithium-ion batteries. From 5 kVA upward a 48 V battery is the better base, as it keeps the DC current and the cable size within reason.
How to choose
Size the unit by continuous load in VA and by motor inrush current, then pick the battery voltage. For a grid-connected ESS with PowerAssist up to 100 A, the MultiPlus-II at 3–15 kVA is the newer platform, with IP22 and EN 50549-1 certification. Where a generator backs up the grid, the Quattro accepts 2 AC inputs and switches between them on its own. If the battery is charged by another device and only inversion is needed, the Phoenix Inverter Smart at 1,200–5,000 VA is simpler. With PV in the project, the Multi RS Solar 48/6000 hybrid inverter adds 2 trackers up to 450 V.

FAQ
What is the MultiPlus transfer time?
Under 20 ms, so the unit works as a UPS for computers and controls.
How many MultiPlus units can run in parallel?
Up to 6 units, which can also form a 3-phase system.
What power ratings does the MultiPlus come in?
From 500 VA to 5 kVA, with a separate 48 V model rated 20 kW.
Can the MultiPlus charge a lithium battery?
Yes, it is compatible with lithium-ion batteries. The charge profile is set to the battery type, and a LiFePO4 bank runs with its BMS.
How is a 3-phase system built from MultiPlus units?
One unit or a parallel group goes on each phase, with up to 6 units in total. The units are of the same model and linked to each other over VE.Bus.
