Description
High-current multi-MPPT handles complex roofs and modules facing different directions, with up to 28 A per tracker and a single string able to use all of it. The 15–25 kW models have 4 DC inputs, and the 27–33.3 kW models have 8. The MPPT range is 150–870 V, feed-in starts at 150 V and maximum DC voltage is 1,000 V. Replaceable AC and DC SPDs are built into the housing next to insulation monitoring, a DC disconnector, an RCMU and reverse polarity protection, and AFCI arc fault protection is included. AC cable of 4–35 mm² aluminum or copper enters through an M32 gland. Ingress protection is IP66, cooling uses Active Cool Technology, and the operating range is −40 to +60 °C. The inverter is made in Austria.
How to choose
Choose the rating by array size. The Verto 25.0 takes up to 37,500 Wp of modules and the Verto 33.3 up to 50,000 Wp, which is one and a half times the AC rating. Note that the larger 4 MPPT models are bigger, 865 × 574 × 279 mm and 41.75 kg against 35.2 kg. If a battery and backup are needed, take the hybrid Verto Plus at 15–33.3 kW, and for 50 kW per unit the Tauro fits.

FAQ
How many MPPTs does the Verto 33.3 kW have?
4 MPPTs and 8 DC inputs, like all 27–33.3 kW models.
What is the maximum input voltage of the Verto inverter?
1,000 V DC, with an MPPT range of 150–870 V.
Does Verto have built-in surge protection?
Yes, the IP66 housing contains replaceable AC and DC SPDs plus AFCI.
What is the efficiency of the Verto inverter?
Peak efficiency is 98.53–98.56 % on the 15.0–25.0 models and 97.98–98.03 % on the 27.0–33.3 models.
How loud is the Verto in operation?
Below 56.5 dB(A) for the 3 MPPT versions and below 54.6 dB(A) for the 4 MPPT versions, so it is better kept away from bedroom windows.
