All inverters in this product family come in three variants. On the M variant with one input per MPPT, a DC isolation switch is integral. Variant XL offers you a full range of features:
- Integral DC switch
- 4 string inputs per MPPT
- Fuse protection on DC positive inputs (XL-F version has additional fuse protection on DC negative inputs also)
- DC surge protection device type 1+2 on each MPPT input.

The inverters operate using three separate MPP trackers that can handle both symmetrical and asymmetrical loads to allow for optimum adjustment for complex setups. Three MPP trackers can also compensate for mismatches between modules, such as those resulting from temperature differences and uneven solar radiation or shading.
The input voltage window of all units is extremely wide: the inverters generating from a 250 V startup voltage, and continuing to feed in down to 200 V DC.
Their peak efficiency is approximately 98%, with a European Efficiency partly also up to an impressive 98%. Even in the lower power ranges, the units have a very high partial load performance, operating at 95% efficiency at just 5% rated power.
