• Max PV input voltage: 1000V
• Rated PV voltage: 650V
• MPPT operating range: 110 – 950V
• Max DC input current: 20A per MPPT
• Battery voltage range: 120 – 800V (HV lithium)
• Max charge / discharge current: up to 50A (dual port)

Battery Storage & Scalability

The SolaX X3 Hybrid G4 PRO 12kW is designed with scalability in mind, making it particularly well suited to larger residential installations and commercial-scale battery storage systems. Unlike the standard G4 model, the PRO features dual independent battery ports, allowing higher charge and discharge currents when connected in parallel and offering greater scalability when designing larger battery banks.

This architecture enables the inverter to support higher-capacity high-voltage battery systems without bottlenecks, improving performance during peak demand, EPS backup operation and energy arbitrage use cases. As battery storage requirements grow over time, the dual-port design allows systems to be expanded more easily, making the G4 PRO an excellent choice for future-proofed commercial and high-demand energy storage installations where higher battery throughput and scalability are required.

It is compatible with SolaX Power’s range of high-voltage lithium battery systems, making it suitable for both new installations and staged battery expansions.
