⚡ GoodWe MS G3 9.9kW Single-Phase Solar Inverter

The GoodWe MS G3 9.9kW is a high-performance single-phase grid-connected inverter designed for large residential solar installations requiring maximum energy output, advanced smart control, and exceptional system flexibility. Engineered for modern high-power PV systems, it delivers outstanding efficiency and reliable long-term performance.

🔋 Maximum Energy Generation

The MS G3 Series is built to achieve the highest possible solar yield while reducing energy costs. With an ultra-low startup voltage of just 50V, the inverter begins generating power very early in the morning and continues operating late into the day, ensuring maximum energy harvest even under low irradiation or variable weather conditions.

Its high input current capability (up to 20A per MPPT) allows full compatibility with high-power solar modules, maximizing energy production and improving overall system efficiency and LCOE (Levelized Cost of Energy).

🌤 3 MPPT Design for Complex Roofs

Equipped with 3 independent MPPT trackers, the GW9900-MS-30 is ideal for complex rooftop layouts with multiple orientations or shading challenges. This ensures optimal energy capture from each string, delivering superior system performance throughout the day.

🧠 Smart Energy Management

The inverter supports advanced smart monitoring and load management, giving homeowners full control over their energy usage.

Smart features include:

• 24-hour load consumption monitoring via GoodWe HomeKit 10001 or GM1000
• Smart load control using dry contact output
• Intelligent management of high-power appliances such as HVAC systems and heat pumps

These features help maximize self-consumption and reduce electricity costs.

🛡 Advanced Safety & Protection

Designed with safety and reliability in mind, the MS G3 includes multiple optional protection features:

• Optional Arc Fault Circuit Interrupter (AFCI) for fire prevention
• Optional Type III Surge Protection Device (SPD) on AC & DC sides
• Optional PID recovery function for improved module performance

These protections ensure safe and stable operation even in demanding environmental conditions.
