Chinese inverter and storage system manufacturer GoodWe has released its EO G2 Series, a single-phase off-grid inverter platform designed to address unreliable grids, frequent power interruptions, and limited electricity access in rural and underserved areas across Africa.
The new inverter series targets residential users, small businesses, and community-scale energy systems requiring reliable backup and off-grid power solutions under challenging operating conditions.
“The challenge is no longer simply access to solar energy, but ensuring reliable power supply under real local conditions,” said Lucas Lu, Managing Director of Africa at GoodWe. “Energy users are increasingly looking beyond upfront cost and evaluating solutions based on their lifetime value, including reliability, durability, and ongoing service support. GoodWe’s EO G2 has been developed with these priorities in mind.”
Available in four power classes — 3.0 kW (GW3K-EO-G20), 3.6 kW (GW3.6K-EO-G20), 5.0 kW (GW5K-EO-G20), and 6.0 kW (GW6K-EO-G20) — the EO G2 series is designed to support a range of off-grid, backup, and hybrid energy applications.
The inverter achieves a maximum efficiency of 98.6%, with a European efficiency rating of 96.8% and an maximum power point tracking (MPPT) efficiency of 99.9%. Each unit supports a maximum PV input current of 21 A per string, enabling compatibility with high-power photovoltaic modules. The series also allows up to 200% PV oversizing to increase solar energy harvesting over the system lifetime.
The 3 kW and 3.6 kW models feature a single MPPT, supporting maximum PV input powers of 6.0 kW and 7.2 kW, respectively. The higher-capacity 5 kW and 6 kW versions include two MPPTs, allowing PV input capacities of up to 10.0 kW and 12.0 kW.
The inverter operates across an MPPT voltage range of 50 V to 480 V, with a maximum input voltage of 530 V and a startup voltage of 60 V.
The new product line also features an IP66 protection rating, aviation-grade connectors, a fully enclosed housing, a patented locking cover, and an extended sealing gasket designed to provide enhanced protection against water and dust ingress. According to the company, the gasket is two to three times wider than conventional market designs.
The series is rated for continuous operation from -35 C to 60 C, allowing deployment in environments ranging from cold climates to hot and dusty regions. It also integrates Ground Fault Circuit Interrupter (GFCI) protection for real-time fault detection and rapid circuit shutdown. Additional protection features include residual current monitoring, PV reverse polarity protection, anti-islanding functionality, and Type III DC and Type II AC surge protection.
The EO G2 operates on a 48 V nominal battery architecture, with a voltage range of 40 V to 60 V, and supports both lithium-ion and lead-acid battery technologies. The 6 kW model can deliver maximum continuous charging and discharging currents of up to 130 A.
When combined with GoodWe’s Lynx A G4 low-voltage battery, the inverter forms an integrated solar-plus-storage solution designed for long-term energy independence, the company said.
The Lynx A G4 battery reportedly supports up to 10,000 charge cycles and 53 MWh of lifetime energy throughput, which GoodWe estimates corresponds to approximately 18 years of operation based on a daily consumption profile of 5 kWh.
The system also incorporates a Mix Parallel Unit (MPU), enabling users to combine older and newer battery units while expanding storage capacity over time. Customers can begin with a 5 kWh battery configuration and increase capacity as energy requirements grow.
For larger energy applications, the EO G2 supports parallel operation of up to 10 inverter units. The system can integrate solar PV, battery storage, diesel generators, grid-connected inverters, and smart loads within a single energy management architecture.
During grid outages, the system can transition into backup mode in less than 4 milliseconds, maintaining continuous operation of connected loads, according to the manufacturer.
The EO G2 also features a 4.3-inch touchscreen display and pre-configured parameters for faster on-site commissioning without additional equipment. Integrated Bluetooth and Wi-Fi connectivity enable remote configuration, system monitoring, and mobile application access.
The inverter also includes five AI-powered smart functions — Agent, Health, Troubleshooting, Forecast, and EMS — designed to automate system diagnostics, energy forecasting, and real-time energy management.
