GoodWe ET PLUS+ GW6.5K-ET 6.5 kW Three-Phase Hybrid Solar Inverter

The GoodWe ET PLUS+ 6.5 kW (GW6.5K-ET) is a three-phase hybrid inverter with high voltage (HV) and 2 MPPT, designed to maximize self-consumption and provide UPS-type backup (<10 ms) for critical loads. Its power electronics support 100% unbalanced outputs, ensuring flexibility for real consumption in homes and small businesses.

Key Features

• 2× MPPT architecture (1 string/MPPT) for two independent orientations.
• HV battery (bus 180–600 V) with efficient bidirectional management.
• MPPT range 200–850 V and max Vdc 1000 V.
• UPS <10 ms and 100% unbalanced output per phase.
• IP66, natural convection cooling (fanless).
• Integrated protections: anti-islanding, DC/AC SPD, insulation monitoring.

Main Electrical Data

• Nominal AC power (grid): 6.5 kW (6.5 kVA).
• Nominal backup: 6.5 kVA; off-grid peak: up to 10 kVA @ 60 s.
• Grid voltage: 400/380 V, 3L/N/PE; frequency: 50/60 Hz.
• Max AC current to grid: ~10 A (according to local standards).
• PV: 2 MPPT (2×1); max Vdc: 1000 V; MPPT: 200–850 V.
• Battery: HV 180–600 V; communication with BMS via CAN/RS485.
• Typical efficiencies: >97% in PV→AC and Bat→AC conversion.

Communications and Monitoring

• With BMS: CAN / RS485; with meter: RS485 (export control).
• With GoodWe portal/app: Wi-Fi/LAN depending on kit; commissioning app.
• Modbus integration (advanced SCADA/EMS projects).

Installation and O&M

• Wall mounting, integrated DC switch and standardized terminals.
• Remote diagnostics and updates via the portal.
• Fanless design: lower maintenance and low noise level.

Dimensions and Weight

• Dimensions (W × H × D): 415 × 516 × 180 mm
• Weight: 24 kg
• Protection rating: IP66; ambient temperature −35…+60 °C

Recommended Applications

• Three-phase homes with self-consumption and critical load backup.
• Small businesses with variable load profiles per phase.

Note for installers: configure power factor, export limit and time-of-use modes according to regulations. Check compatibility/firmware of the HV battery bank and selectivity of protections in the backup circuit.
