Inverters & smart tech
The Intelligence Behind Every Installation.
Panels generate power. Inverters determine how profitably you use it.
The hybrid advantage
Duracell Dura-i — solar and battery in one unit.
The Duracell Dura-i G3 hybrid inverter seamlessly manages both solar generation and battery charging within a single, hyper-efficient unit. One unit replaces what would otherwise require a separate string inverter and battery management system.
- 97.3% peak efficiency (PV→AC), 94.3% (battery→AC)
- 3.6 / 4.6 / 5 / 6kW single-phase models
- IP65 · built-in DC arc fault protection
- 10-year warranty · G98/G99 compliant


Battery retrofit
Already Have Solar? Add a Battery to Your Existing System.
The Fox ESS AC1(G2) is an AC-coupled retrofit inverter engineered to integrate high-capacity storage into any existing solar array — regardless of the original installer or inverter brand. First Choice Solar handles the full retrofit without touching your existing installation.
Growatt integration
Reliable string and hybrid conversion.
Growatt's string and hybrid inverter range delivers reliable, high-efficiency solar conversion engineered for seamless integration with the Growatt ALP5.0L-E1 battery stack. Monitored via the Growatt ShinePhone app with real-time data, remote diagnostics, and automated alerts.
Three-phase range
Duracell Dura-i HV — for larger homes, commercial & agricultural sites.
High-voltage three-phase inverters from 5kW to 50kW, engineered for the volatile, high-load demands of larger properties and commercial rooftops.
