Solax Inverter Review: Is the X1 & X3 Hybrid Good for Ireland?
Solax is one of the more widely fitted hybrid inverter brands on Irish solar installs, with the single-phase X1 and three-phase X3 G4 hybrid ranges and the matching Triple Power battery. Here's our independent review for Irish homes, covering specs, the SolaxCloud monitoring app, the 10-year warranty, and where it sits against the other hybrids on our solar inverter brands hub. If you're cross-shopping, it's worth reading alongside Solis and our wider inverter comparison.
Quick Answer
Solax makes the X1 (single-phase) and X3 (three-phase) G4 hybrid inverters, popular on Irish solar installs from roughly 3kW to 15kW. They pair with the Solax Triple Power (T-BAT) battery range and are monitored through the SolaxCloud app. With around 97.6% peak efficiency, a standard 10-year warranty, and a genuine three-phase option, Solax is a solid mid-market choice, especially for larger rural builds and heat-pump homes.
Who Are Solax Power?
Solax Power is a Chinese inverter and energy-storage manufacturer that has become a familiar name on Irish residential solar systems. Rather than make solar panels, Solax focuses on the hybrid inverter, the battery, and the software that ties a solar-plus-storage system together.
For Irish homes, the appeal is the breadth of the range. The single-phase X1 covers most standard houses, while the three-phase X3 suits larger rural builds, bigger arrays, and heat-pump-led loads that benefit from a balanced three-phase supply. Both pair with the Solax Triple Power (T-BAT) battery and are monitored through the SolaxCloud app.
As with any solar install in Ireland, the grant and grid side stays the same regardless of inverter brand: the SEAI grant is capped at €1,800, domestic solar carries 0% VAT, surplus export is paid through the Clean Export Guarantee (CEG), and the system must be registered with ESB Networks by your installer.

The Solax Product Range
The core of the Solax line-up for Irish homes is the G4 hybrid platform in single-phase (X1) and three-phase (X3) versions, plus the matching Triple Power battery. Here are the three parts you'll typically see quoted:
X1 Hybrid G4 (Single-Phase)
The single-phase hybrid for standard Irish homes on a one-phase supply. Typically specified from around 3kW to 7.5kW and pairs with the Triple Power battery for self-consumption and backup.
X3 Hybrid G4 (Three-Phase)
The three-phase hybrid, a good fit for larger rural builds, bigger arrays, and heat-pump-led loads. Available at higher power ratings, typically up to around 15kW, balancing generation across all three phases.
Triple Power (T-BAT) Battery
The matching Solax battery range, designed to stack to suit your home's storage needs. Sized alongside the hybrid inverter so the whole system is commissioned and monitored as one through SolaxCloud.
