GoodWe Launches 4H Off-Grid Solution for Reliable and Affordable Energy Independence

GoodWe introduces its latest residential energy storage solution, combining the EO G2 Series off-grid inverter with the Lynx A G4 16kWh low-voltage battery. Designed for regions with unstable or limited grid access, the system delivers reliable, flexible, and cost-efficient energy independence for homeowners.

High Protection: Built for Real-World Reliability

Engineered for demanding environments, the EO G2 ensures stable and safe operation across diverse conditions.

With IP66 protection and aviation-grade connectors, the system is fully sealed against dust and water ingress. Unlike conventional systems that require drilling and manual sealing during installation, this design minimizes installation risks while ensuring long-term durability.

The built-in GFCI (Ground Fault Circuit Interrupter) actively detects and interrupts leakage currents, providing a higher level of electrical safety compared to systems relying on external protection devices.

Designed to operate reliably from -20°C to 55°C, the system maintains stable performance in extreme climates, ensuring uninterrupted energy supply even under challenging conditions.

High Efficiency: More Power, Made More Affordable

The EO G2 is designed to extract more value from solar generation without increasing system cost.

With 200% PV oversizing, a 6kW system can support up to 12kW of PV input—allowing significantly higher energy yield without increasing inverter capacity. Compared to conventional systems that require two inverters to handle the same PV size, this translates into lower upfront investment and higher return on investment.

A 21A PV input current per string ensures compatibility with 99% of mainstream high-power modules on the market, giving users greater flexibility in module selection without design constraints.

With up to 98.6% maximum efficiency, the system converts more solar energy into usable electricity, improving long-term energy yield and reducing wasted generation.

High Simplicity: Designed for Effortless Installation and Control

The EO G2 simplifies both installation and daily operation, reducing time and complexity for installers and users.

A 4.3″ touchscreen enables direct on-site configuration, eliminating the need for external devices or complex setup procedures.

With built-in WiFi and Bluetooth, commissioning, monitoring, and updates can be completed wirelessly via the SEMS+ mobile app—enabling faster setup while eliminating the need for additional communication modules.

Supporting up to 10 units in parallel, the system enables seamless capacity expansion without requiring system redesign.

High Versatility: One System for Every Scenario

The EO G2 adapts to a wide range of energy scenarios, offering greater flexibility than single-mode systems.

It supports multiple energy sources—including grid, PV, ESS, and generator, enabling smooth coordination between different power inputs where conventional systems may have limited compatibility.

With whole-home backup capability, it ensures continuous power supply during outages, rather than supporting only selected loads as in basic backup solutions.

A <4ms seamless switching time enables near-instant transition during grid failure, significantly reducing the risk of disruption.

Lynx A G4 16kWh: Strong Power, Long-Term Reliability

The Lynx A G4 16kWh is a low-voltage battery system designed to deliver reliable, safe, and flexible energy storage for residential applications.

Built with 314Ah high-capacity cells, the system provides higher energy density per unit, reducing the number of battery modules

Supporting 0.5C continuous charge and 0.63C continuous discharge, it delivers strong power output for high-load appliances and short-term backup scenarios.

With up to 8000 cycles, the battery ensures long-term durability and stable performance, delivering greater lifecycle value and reducing replacement frequency over time.

Multi-Layer Protection

Safety is embedded at every level of system architecture.

Featuring thermal runaway prevention, thermal-electric separation, and optional aerosol fire suppression, the system minimizes risk at both cell and system levels for enhanced safety.

The IP65-rated prevents dust and moisture ingress, enhancing operational safety in real-world environments. An optional low-temperature heating module enables stable operation from -20°C to 55°C, ensuring reliable performance even in extreme climates.

Expand Without Constraints

The Lynx A G4 is designed for flexible and cost-efficient system expansion.

Supporting up to 30 units in parallel, it enables seamless capacity scaling as energy demand grows.

With its dual-terminal design, batteries can be connected in a daisy-chain configuration, eliminating the need for additional busbars or complex external wiring—reducing both installation cost and complexity.

The system also supports a self-developed Mix Parallel Unit, enabling compatibility with multiple low-voltage battery models, including upcoming Lynx A G4 5kWh and 10kWh versions—allowing flexible expansion without replacing existing systems.

Simplified Installation and Maintenance

Designed with installers and end users in mind, the Lynx A G4 reduces both installation effort and long-term maintenance cost.

The built-in circuit breaker eliminates the need for additional external components, simplifying system configuration and reducing upfront cost.

Supporting both wall-mounted and floor-standing installation, the system adapts easily to different installation environments. With a compact and lightweight design, along with optional wheels, transportation and installation become significantly more efficient.

An integrated current limiting module enables faster pre-charging during initial startup, smoother battery expansion, and automatic parallel recovery after faults—reducing commissioning time, minimizing downtime, and lowering service costs.

A Complete and Future-Ready Energy Solution

Together, the EO G2 Series and Lynx A G4 16kWh form a fully integrated off-grid energy solution. The system delivers reliable power supply, flexible scalability, and optimized cost performance—helping homeowners achieve greater energy independence with a solution that is built to adapt, expand, and last.

This launch reflects GoodWe’s continued commitment to advancing user-centric energy innovation. Built on its 4H system concept, the solution addresses the specific challenges of regions with unstable grid infrastructure, balancing performance, reliability, and ease of use.

By continuously translating local market insights into targeted product design, GoodWe delivers tailored energy solutions that meet diverse household needs across regions—supporting a more accessible and resilient energy future worldwide.
