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:

SMA Tripower Commercial String Inverters

For 40 years, SMA has been setting technological trends and driving the development of renewable energies. SMA energy systems specialise in making practical use of as much self-generated power as possible.

Sunny Tripower CORE1

The SMA Sunny Tripower CORE1 inverter is at the core of our commercial systems. It converts the direct current generated by the roof-mounted PV system into alternating current, as required in your business.

Its unique, free-standing design allows the Sunny Tripower CORE1 to be installed 60% faster than other string inverters. The innovative, fully integrated design of the CORE1 ensures low balance of system (BoS) costs, simpler project processes and lower material expenses. It sets new standards for decentralized rooftop and ground-based PV systems and covered parking lots.

Thanks to its versatility, it has become the first choice for commercial PV projects, enjoys great popularity and has unlimited delivery capacity.

Other features:

  • With a capacity of 50 kW, it is easily scalable up to the megawatt range
  • Innovative, fully integrated stand design reduces logistics, installation and material outlay
  • Increased annual energy yields and reduced system-specific energy costs through over-dimensioning of the PV system of up to 150%
  • Constant tracking of your energy yields through the web portal or an app.

Sunny Tripower CORE2

The Sunny Tripower CORE2’s flexible system design is the ideal inverter for decentralized structures for larger commercial PV systems up to the megawatt range.

With 110 kilowatts, 24 strings and 12 MPP trackers, the Sunny Tripower CORE2 allows for a particularly high solar coverage in ground-mounted PV systems as well as at different roof pitches during the day.

Other features:

  • More flexibility in string design
  • Suitable for both rooftops and ground-mount
  • Future-proofed for more integration options
  • The integrated ShadeFix software solution automatically optimizes system performance anytime, even with partially shaded modules
  • The automatic monitoring service SMA Smart Connected also ensures maximum PV system yields by detecting failures as fast as possible.
