X3-MIC-6K-G2
The Solax X3-MIC-6K-G2 is a 6 kW three-phase string photovoltaic inverter with 2 independent MPPTs and an integrated DC switch, ideal for three-phase residential and commercial systems. Maximum efficiency of 98.3%, PV oversizing up to 200%, integrated export control, IP65 protection, CEI 0-21:2022 certification, and 10-year warranty (with active cloud).
The Solax X3-MIC-6K-G2 is a 6 kW three-phase string photovoltaic inverter from the second generation X3-MIC series, designed for residential and commercial photovoltaic systems with three-phase supply. With a maximum efficiency of 98.3%, 200% PV oversizing, and integrated global MPP scanning, it is the ideal solution for those looking to maximize solar production in three-phase systems without storage.
Why choose a three-phase string inverter?
Three-phase supplies — medium and large homes, warehouses, commercial activities with a three-phase meter — benefit from a three-phase inverter because solar production is distributed evenly across the three phases, avoiding imbalances and distributor penalties. The X3-MIC-6K-G2, thanks to its 2 independent MPPTs with integrated DC switch, is also excellent for roofs with multiple orientations (e.g., east/west slopes) or with partial shading, managing the two strings completely independently.

Main Features
The X3-MIC-6K-G2 supports parallel connection of up to 60 inverters via the Solax Datahub system (using Modbus), ideal for medium-scale systems requiring centralized production management and export control. Smart load management (heat pump, via adapter box) and optional 24/7 monitoring via Wi-Fi, LAN, or 4G complete this compact and reliable product. Natural cooling (fanless) ensures quiet operation and reduced maintenance.
Frequently Asked Questions
Can the Solax X3-MIC-6K-G2 manage a storage system with batteries?
No, the X3-MIC is a pure string inverter and does not manage batteries. To add storage to a three-phase network, you need a three-phase hybrid inverter (e.g., Solax X3-HYBRID-6.0-D) or an AC-coupled system. If you plan to have storage from the start, it is more convenient to opt directly for a three-phase hybrid inverter.
Is the X3-MIC-6K-G2 CEI 0-21 certified for the Italian grid?
Yes, the X3-MIC-6K-G2 is CEI 0-21:2022 certified, a mandatory requirement for connection to the low voltage distribution grid in Italy and for access to GSE incentives. CEI 0-16 certification (medium voltage connection) is not provided for this model.
How many panels can be connected to the X3-MIC-6K-G2?
Thanks to the 200% PV oversizing, you can connect modules for a total peak power of up to 12 kWp, divided over 2 independent strings. The maximum DC voltage is 1,000 V and the maximum current per string is 16 A, compatible with the latest generation modules from 400-600 Wp.
How does the parallel connection of the X3-MIC-6K-G2 work?
The X3-MIC-6K-G2 supports parallel connection of up to 60 inverters via the Solax Datahub system (Modbus RS485 communication). In this setup, the Datahub acts as the master and manages centralized production, export control, and aggregated monitoring. All inverters must have identical firmware for correct parallel operation.
Is the Solax X3-MIC-6K-G2 suitable for roofs with dual east/west exposure?
Yes, the 2 independent MPPTs allow you to connect two strings with different orientations and inclinations (e.g., east slope + west slope), each managed at its own maximum power point. This maximizes production in the morning and evening hours, increasing the total energy produced compared to a system with a single MPPT.
