Trade only product - MCS or NICEIC membership required

Upgrade your PV system seamlessly with the SolaX X1-AC 3.0kW Single Phase AC Coupled HV Inverter. This retrofit solution, compatible with any brand of single-phase inverter, delivers maximum efficiency of up to 96.5%. Whether installed indoors or outdoors, it allows for remote monitoring through the XCloud, providing flexibility and control over your solar energy system.

Note: The X1 AC inverter supports a minimum of 1 and a maximum of 3 batteries. It's essential to use batteries of the same capacity, as different capacities cannot be connected to one inverter.


  • High Voltage Battery Support: Requires thinner cables, enhancing installation efficiency.
  • 7.5kW Max Charge/Discharge: Ensures optimal energy management.
  • SolaX WiFi Stick: Enables remote monitoring via XCloud, enhancing user accessibility.
  • Grid Trading Applications: Responds in less than 0.5 seconds, suitable for grid trading applications.
  • Charging from Grid: Allows charging directly from the grid for added flexibility.
  • Natural Cooling: Operates quietly with low maintenance requirements.

Note: This inverter does not support CT's; only meters. Please use SolaX-1P-Meter-CT.

Key Features:

This high-quality inverter efficiently converts solar energy into AC energy, storing it in a battery for future use. Noteworthy features include:

Operating Modes:

The SolaX X1-AC 3.0kW Single Phase AC Coupled HV Inverter offers four operational modes catering to diverse needs:

  1. Self-Use (Default): Prioritises local loads, utilising grid power only when the battery capacity is insufficient.
  2. Back Up: Preserves higher battery capacity when the grid is on, discharging only during grid outages.
  3. Feed-in Priority: Maximises feed-in tariff benefits by prioritising grid feeding, load supply, and battery charging.
  4. Force Time Use: Allows flexible scheduling of charging and discharging times, with the option to charge from the grid.
