110K-10T / 125K-10T grid-tied string inverter 110–125 kW
Country: Germany · Model: 110K-10T / 125K-10T
A string inverter of 110 or 125 kVA with 10 MPP trackers that delivers 100 % power at 45 °C. It works at large rooftop and ground-mounted solar plants, where the array is divided into many groups with different orientation, shading or string length.

Description
The peak array power reaches 150 kWp for the 110K-10T and 165 kWp for the 125K-10T, and each tracker accepts two strings. The MPPT window is 500–890 V, the limit DC voltage 1100 V. The output is designed for three-phase 380, 400 or 415 V grids with neutral. Maximum efficiency reaches 98.6 %, European efficiency 98.3 %. The IP66 case measuring 695×970×325 mm and weighing 75 kg works from −30 to +60 °C, so it can be installed outdoors even in driving rain. Built-in features are recovery of modules after PID degradation, AFCI arc protection and string monitoring separately on each tracker, so a faulty string is visible in monitoring without walking the array with a tester. The unit is certified to EN 50549-1/2, VDE-AR-N 4105/4110 and IEC 62109-1/2.
How to choose
The model is chosen by the peak array power and the temperature at the installation site. For an array of up to 150 kWp the 110K-10T is taken, up to 165 kWp the 125K-10T, and both hold their rating up to 45 °C. A roof of 75 kWp is covered by the 50K-4T. If the plant is large and designed with an 800 V grid and a 1500 V DC array, it is more appropriate to take the 250K-6T of 250 kVA or the 350K-8T up to 352 kVA.

FAQ
Does the 125K-10T derate in heat?
The inverter delivers the full 125 kVA at an air temperature of up to and including 45 °C. On a roof with strong heating it is still better to place it in shade so as not to exceed this limit.
Why does a string inverter need a PID recovery function?
PID degradation reduces module output because of the potential difference between the cells and the grounded frame. Built-in recovery returns part of the lost power without a separate device in the array.
How does the 110K-10T help find a faulty string?
The inverter monitors strings separately on each of the 10 MPP trackers, so a drop on one of them is immediately visible in monitoring. The working window of the trackers is 500–890 V.
To which grids can the 110K-10T and 125K-10T be connected?
To three-phase 3P/N/PE grids of 380, 400 or 415 V. In the Ukrainian 400 V grid the inverter works without an intermediate transformer.
