GoodWe ET PLUS+ GW5K-ETR 5 kW Three-Phase Hybrid Solar Inverter

The GoodWe ET PLUS+ GW5K-ETR is a three-phase hybrid solar inverter with 5 kW output, designed to maximize self-consumption and provide fast backup for demanding homes and small businesses. Its high-efficiency electronics, compatibility with high-voltage batteries (180–600 V), and IP66 rating ensure reliable installation indoors or in protected outdoor areas, with complete monitoring via the manufacturer's app and portal.

Main Features

• Nominal AC Power: 5 kW three-phase (230/400 V, 50/60 Hz).
• UPS Function: backup switching <10 ms for critical loads.
• PV Tracking: 2 independent MPPTs, optimizes mixed roofs and partial shading.
• Maximum PV Input: up to 7.5 kW DC; max. PV voltage 1000 V.
• MPPT Range: 200–850 V; typical startup from 160 V.
• HV Battery: range 180–600 V; 25 A continuous charge/discharge.
• Efficiency: high conversion performance, with nighttime self-consumption <15 W.
• Protections: anti-islanding, AC overcurrent/overvoltage, PV reverse polarity, insulation monitoring, and SPD.
• Connectivity: Wi-Fi for portal; RS-485 for meter/EMS; CAN for battery BMS.
• Protection rating: IP66; natural convection cooling.

Dimensions and Weight

• Device dimensions: 415 × 516 × 180 mm.
• Weight: 24 kg.
• Mounting: wall-mounted, with space for perimeter ventilation.

Advantages

• Optimized self-consumption thanks to 2 MPPTs and oversizable PV input.
• Service continuity during outages with switching <10 ms.
• Quick and clean installation: compact design, IP66, and fanless.
• Comprehensive management: monitor, update, and adjust parameters via app/portal.

Recommended Applications

• Homes with high consumption (heat pump, EV, electric kitchen).
• Small businesses requiring three-phase backup for essential loads.
• Projects with dynamic tariffs and time-based savings strategies.

Installation and Best Practices

• Mount on a rigid, level surface; maintain ventilation clearances.
• Design strings within the voltage/current limits of each MPPT.
• Complete DC/AC protections and isolation according to local regulations.
• Connect certified HV battery and verify CAN communication with the BMS.
• Commission using the app: portal registration, firmware update, and backup tests.

The GW5K-ETR combines high efficiency, ultra-fast backup, and professional connectivity in a robust, compact unit. A future-ready solution that balances performance, reliability, and easy O&M for self-consumption installations with storage.
