Description
The HU versions work with low-voltage batteries and the XHU are designed for high-voltage AXE, so the battery type determines the version before purchase. A PV input voltage of up to 1000 V makes it possible to build long chains of modules on the roof of a farm or warehouse with fewer strings. The maximum efficiency reaches 98 %. A separate input accepts a diesel generator, which picks up the load when the battery is discharged and there is no grid. AC- and DC-coupled schemes are supported, so the WIT is added to an existing grid-tied solar plant or a system is built from scratch. The IP66 enclosure is mounted outdoors. 4–25K-HU inverters are combined into a system of up to 90 kW.
How to choose
First decide on the battery, because a low-voltage one needs the HU version and a high-voltage AXE needs the XHU version. Power is selected by the total load of the three phases; for a house the 4–25 kW range is usually enough, and on a farm or in a workshop 29.9–50 kW is more suitable. For a single-phase house with a low-voltage battery it is simpler to take the SPE of 3.5–12 kW, and for an off-grid site with heavy motors the transformer-based SPF T of 3–18 kW is better.

FAQ
Which battery should be connected to the WIT XHU?
The XHU version works with high-voltage AXE batteries, and the HU version with low-voltage batteries.
Can a diesel generator be connected to the WIT hybrid inverter?
Yes, the WIT has a separate diesel generator input, so the backup source works in one scheme with the battery and the solar plant.
What is the maximum PV voltage of WIT inverters?
The maximum PV input voltage is 1000 V, which suits long strings on commercial roofs.
What power can a WIT 4–25K-HU system be scaled to?
Several 4–25K-HU inverters are combined into a common system of up to 90 kW.
Can the WIT inverter be installed outdoors?
Yes, the enclosure has IP66 protection and withstands rain and dust. It is better to choose a shaded place so that the inverter does not heat up in the sun.
