Smart Features and Monitoring
The X3-MIC-8K-G2 supports Solax cloud monitoring via optional Wi-Fi Plus or Pocket LAN dongles, with real-time production access from the app and web portal. The integrated export control (zero feed-in) can be managed via an external meter, which is essential for systems subject to feed-in restrictions imposed by the local utility.
Installation and Compatibility
The inverter is designed for wall mounting and weighs only 17 kg, making installation easy even in tight spaces. It is compatible with the Solax MateBox for tidy cable management and with the centralized monitoring system via DataHub in multi-inverter installations.
Frequently Asked Questions
What does 200% oversizing mean on the X3-MIC-8K-G2?
It means you can connect up to 16 kWp of photovoltaic panels to the 8 kW inverter. Oversizing is a common practice that maximizes production during low irradiance hours (morning, evening, cloudy days), accepting limited clipping during peak sunlight hours. It is especially advantageous for systems with east-west oriented roofs.
Does the Solax X3-MIC-8K-G2 support zero feed-in functionality?
Yes, export control (zero feed-in) is integrated into the X3-MIC-8K-G2. You need to connect a bidirectional meter at the grid connection point, which communicates with the inverter to limit the exported power in real time. This function is often required by local utilities for large residential systems.
Is a Wi-Fi dongle needed to monitor the X3-MIC-8K-G2?
Yes, cloud monitoring requires the separate purchase of a connectivity dongle: Pocket Wi-Fi Plus 3.0 or Pocket LAN 2.0. Once connected, the inverter transmits production data to the Solax Cloud platform, accessible via app and web portal with historical data, alarms, and energy statistics.
Is the X3-MIC-8K-G2 suitable for a three-phase home installation?
Yes, it is specifically designed for three-phase users. It produces balanced three-phase alternating current, ideal for homes with a three-phase supply contract, heat pumps, industrial air conditioners, or three-phase loads. The 8 kW power output effectively covers the needs of large homes or villas with high energy consumption.
Can the X3-MIC-8K-G2 be paired with a battery?
No, the X3-MIC-8K-G2 is a string (grid-tied) inverter and does not support direct battery connection. For systems with storage, Solax offers the X3-Hybrid G4 series (three-phase hybrid inverter) or the integrated X3-IES system, both compatible with high-voltage batteries. The MIC is the optimal choice for photovoltaic-only systems without storage.
