X3-PRO-17K-G2
The Solax X3-PRO-17K-G2 is a 17 kW three-phase string photovoltaic inverter from the X3-PRO G2 series. With 2 MPPT, efficiency up to 98.5%, IP66 protection, and PV oversizing up to 150%, it covers the intermediate range between 15 and 20 kW for commercial and light industrial installations.
The Solax X3-PRO-17K-G2 is a 17 kW three-phase string photovoltaic inverter from the X3-PRO G2 series. It covers a power size that is particularly sought after by installers for light commercial systems where 15 kW is insufficient but 20 kW exceeds the needs or connection limits.

Why choose the 17 kW size?
The 17 kW size is often preferred in GSE connection procedures for systems that need to stay below specific contractual thresholds, or when the sizing of the PV system targets a generator between 20 and 25 kWp with 150% oversizing. With a maximum efficiency of 98.5% and the same compact 26 kg chassis as the rest of the series, it offers the same construction features as the PRO-15K and PRO-20K.
Frequently Asked Questions
Why choose 17 kW instead of 15 or 20 kW?
The 17 kW size covers a precise design gap: it is larger than the 15 kW when the system requires more capacity, but remains below the 20 kW threshold, which in some connection contracts or incentives imposes additional constraints. It is also ideal for PV generators from 22–25 kWp with 150% oversizing, where a 15K would be undersized and a 20K oversized.
Is the X3-PRO-17K-G2 structurally identical to the 15K and 20K?
Yes, all models in the X3-PRO G2 series (from 10K to 20K) share the same chassis, the same dimensions (482 × 417 × 181 mm), and the same weight (26 kg). Only the nominal power and internal configuration change. This simplifies logistics and warehousing for installers working with multiple sizes.
How many kWp of panels can be connected to the X3-PRO-17K-G2?
With 150% oversizing, it is possible to connect up to 25.5 kWp of photovoltaic generator. For commercial rooftop systems with predominantly south-facing orientation, this ratio is optimal for maximizing production while keeping clipping within acceptable limits.
Does the X3-PRO-17K-G2 support zero export control?
Yes, export control is integrated into the X3-PRO G2. You need to connect a bidirectional measurement meter at the point of connection with the grid to enable the function. The Solax CT meter or a compatible RS485 meter is the accessory to add for this functionality.
Is the X3-PRO-17K-G2 compatible with the Solax MateBox?
Yes, the X3-PRO G2 is compatible with the Solax MateBox Advanced, which simplifies wiring by collecting AC, DC, and communication connections in a single accessory to be installed above the inverter. It is particularly useful in installations where speed and tidy wiring are priorities.
