Description
The range is divided into five bands: 30–36, 40–50, 60–80, 70–110 and 120–136 kW, and this is enough for anything from a warehouse roof to a small ground-mounted plant. The maximum PV array voltage is 1100 V, and 1000 V in the G03 series, which is taken into account when calculating the number of modules in a string. Each tracker accepts current of up to 40 A, so two strings of powerful large-format modules can be connected to one input. Models from 60 kW have built-in type II SPDs on the DC and AC sides, which simplifies the assembly of combiner cabinets. Zero export is needed by businesses that run on their own consumption without selling to the grid, and VSG makes the inverter more stable on weak lines.
How to choose
Inverters are selected so that the array power falls within the range of a series, taking the DC/AC ratio into account, and the number of trackers matches the number of orientations and module types. For sites up to 36 kW the smallest series is enough, and for a large factory roof the 120–136 kW units are taken and several are installed. Small private sites with a single-phase supply are covered by the SUN-G P1 rated 1–10.5 kW with a start-up voltage of 80 V, and if backup from a battery is needed, a hybrid inverter is required.

FAQ
What is the maximum PV voltage of the 30–136 kW commercial inverters?
1100 V for most models and 1000 V for the G03 series, and the string length depends on it.
How many MPPT trackers are there and what is the current per tracker?
Depending on the power 2–8 trackers, each accepting up to 40 A.
Does the commercial inverter have built-in surge protection?
Models from 60 kW have type II SPDs on the DC and AC sides. For the smaller models the need for external SPDs is defined by the design.
What is the efficiency of the SUN-G03/G04/G01P3 three-phase inverters?
The maximum efficiency is 98.6–98.8 % depending on the model.
Can a commercial solar plant work without feeding into the grid?
Yes, zero export mode limits the generation of the 30–136 kW inverters to the level of the enterprise own consumption.
