String Inverters

What is a String Inverter?


A String Inverter is the most commonly used inverter in home and commercial solar power systems. It converts electricity from multiple panels or a string of panels. String Inverters can be used for grid-tied, hybrid and off-grid applications.


SolaX X1 Grid Tied Inverter Series

SolaX X1 BoostSolaX Power, a solar company unrivalled for its quality, reliability and efficiency, and renowned for its impressive Hybrid Inverter range, now has a range of single phase (grid-tied) string inverters.

The SolaX X1 single phase inverters boast a wide MPPT (maximum power point tracker) voltage range to allow you to harvest the maximum amount of energy possible from your PV system and have a maximum input voltage of 600V, with a maximum efficiency up to 97.8%.

Other features within the range include:

  • IP65 rating – dust tight and waterproof – suitable for indoor or outdoor mounting
  • Remote system monitoring via X-Cloud (on some models)
  • ‘Smart Plug’ load control allows for device remote control (optional on some models)

We are currently supplying the X1 Mini and the X1 Boost. Download the X1 Series datasheet:
