SolaX X3 Inverter Monitoring — Three-Phase Dashboard
Comprehensive monitoring for SolaX X3-Pro and X3-Mega three-phase inverters. Track all three phases, production, and grid interaction.
Three-Phase Monitoring Done Right
SolaX X3 series inverters (X3-Pro, X3-Mega, X3-MIC) are designed for larger residential and commercial installations. With three-phase output, they produce more data than single-phase units — and Solax Monitor handles it all.
See per-phase voltage, current, and power alongside total system output. The dashboard adapts to show all three phases clearly, so you can spot imbalances or issues at a glance.
Compatibility checked against SolaX documentation
Check the exact model before installing
SolaX uses different firmware, communication modules and register maps across generations. This table is a practical starting point, not a blanket promise for every inverter carrying the same family name.
| Model | SolaX reference | Local connection |
|---|---|---|
| X3-MIC G2 | ARM V1.17 | Supported WiFi/LAN path; dongle firmware matters |
| X3-PRO G2 | ARM V1.17 | Supported WiFi/LAN path; dongle firmware matters |
| X3-MEGA G2 | ARM V008.02 | Supported WiFi/LAN path; dongle firmware matters |
| X3-FORTH | ARM V015.01 | Supported WiFi/LAN path; dongle firmware matters |
| X3-FORTH Plus | ARM V002.01 | Supported WiFi/LAN path; dongle firmware matters |
| X3-GROUND | ARM V1.00 | Supported WiFi/LAN path; dongle firmware matters |
The firmware shown is the version named by SolaX. Newer firmware can work, but the local data path and register map still need checking.

What we verify before enabling control
- Stable read-only telemetry on the exact hardware.
- Fields that match the correct register map.
- Writable registers and safe restore behaviour before Modbus writes are enabled.
Three-Phase Dashboard
Per-phase AC voltage, current, and power output. Spot phase imbalances instantly.
High-Power Systems
Built for X3-Pro (8–30 kW) and X3-Mega (40–60 kW) class inverters.
Multi-MPPT Tracking
Track up to 3 MPPT inputs with individual string voltage and power data.
Commercial Ready
Suitable for commercial installations with detailed energy analytics and export tracking.
X3 Data Points
Your SolaX X3 provides detailed three-phase telemetry. Solax Monitor displays:
- Per-phase AC output: voltage (V), current (A), and power (W) for L1, L2, L3
- Total three-phase output power and daily production
- Multiple MPPT string inputs with individual tracking
- Grid import/export totals with per-phase breakdown
Analytics for Larger Systems
Three-phase systems often have higher production, which means bigger savings. Solax Monitor's analytics calculate your cost savings accurately, accounting for time-of-use rates if you configure them.
For larger three-phase installations, self-sufficiency is one of the numbers worth watching. It shows how much of your real consumption is covered by your own production across days, weeks and months.
Frequently Asked Questions
Which X3 models does Solax Monitor support?
All SolaX X3 series three-phase inverters: X3-Pro (8–30 kW), X3-Mega (40–60 kW), X3-MIC, and X3-FIT. If the inverter appears in SolaxCloud, it works with Solax Monitor.
Can I see individual phase data?
Yes. The dashboard shows voltage, current, and power for each phase (L1, L2, L3) individually, plus the total three-phase output. This helps identify phase imbalances or wiring issues.
Is Solax Monitor suitable for commercial X3 installations?
Yes. Solax Monitor handles the higher data volumes from commercial X3 inverters. The analytics page provides detailed production and export data useful for ROI tracking on commercial solar installations.
Does the X3-Pro support multiple MPPT tracking?
Yes. The X3-Pro has up to 3 MPPT inputs, and Solax Monitor shows voltage and power for each string separately. That is useful when you are looking for a weak string or shading on larger arrays.
