X3-PRO-30K G2
The Solax X3-PRO-30K G2 is the 30 kW three-phase string inverter — the largest model in the X3-PRO G2 series. 98.5% efficiency, 3 MPPT (6 inputs), max DC voltage 1100 V, 150% oversizing, IP66 protection, SPD Type II, Master/Slave parallel function. Certified CEI 0-21 and CEI 0-16.
The Solax X3-PRO-30K G2 is a 30 kW three-phase string photovoltaic inverter, the largest model in the X3-PRO G2 series, ideal for commercial systems, industrial warehouses, and large residential installations with photovoltaic arrays up to ~45 kWp. With a maximum efficiency of 98.5% and IP66 protection, it delivers high performance in any environmental condition.
Key Technical Features
The X3-PRO-30K G2 integrates global MPP scanning to maximize output even in partial shading conditions, integrated export control to comply with feed-in limits imposed by the distributor, and smart load management (heat pump via Adapter Box, Solax EVC wallbox). The DC oversizing up to 150% and AC overload up to 110% ensure flexibility in system design. Type II SPD protection on both AC and DC sides and optional AFCI protection make the system safe even in industrial environments.

When to choose the 30K over the 25K?
The X3-PRO-30K G2 is the right choice when the system requires a nominal power higher than 25 kW—typically for three-phase users with average consumption of 20–28 kW. With the same size and weight, it offers 20% more power. The 30K model is the flagship of the X3-PRO G2 series: for higher power, you move directly to the X3-MGA G2 series (40–60 kW). For systems that also require storage, it should be paired with a retrofit inverter X3-FIT G4.

Frequently Asked Questions
Does the X3-PRO-30K G2 have 3 MPPT or 2 like the 25K?
The X3-PRO-30K G2 features 3 MPPT (with 2 strings per MPPT, for a total of 6 string inputs), unlike the 25K model which has 2 MPPT. This allows you to connect PV arrays on 3 different orientations or exposures, optimizing yield in systems with complex roofs or multiple slopes.
Can the X3-PRO-30K G2 operate with Master/Slave parallel connection?
Yes. The X3-PRO G2 series supports the Master/Slave function for parallel connection of multiple inverters. This allows you to scale the system power beyond 30 kW by connecting multiple units at the same connection point, useful for C&I systems with power between 30 and 90 kW without having to move to larger inverter sizes.
What is the difference between X3-PRO-30K G2 and X3-MGA-40K-G2?
They are two different series: the X3-PRO-30K G2 (30 kW, 3 MPPT, 28 kg) is the largest model in the PRO G2 series, compact and designed for medium commercial systems. The X3-MGA-40K-G2 (40 kW, 5 MPPT, 44 kg) is the smallest model in the MGA (Mega) G2 series, designed for larger systems with greater string flexibility (up to 10 inputs). They have significantly different physical sizes and weights.
Does the X3-PRO-30K G2 support 24/7 monitoring?
Yes, via optional connectivity dongle (Pocket WiFi 3.0, Pocket LAN 3.0 or Pocket 4G 3.0) connected to the inverter's communication port. With the dongle connected, the inverter sends real-time production data to SolaX Cloud, accessible via mobile app and web portal for monitoring and production history.
Is the X3-PRO-30K G2 compatible with the Solax EMS PRO 1000?
Yes. The X3-PRO-30K G2, like all Solax G2 string inverters, is compatible with the EMS PRO 1000 system via RS485 communication. In systems with multiple inverters, the EMS PRO 1000 enables centralized supervision, aggregated export control, and energy reporting on all connected inverters.
