GoodWe EM GW3048-EM 3.9 kW Single-Phase Hybrid Solar Inverter

The GoodWe EM (GW3048-EM) is a single-phase hybrid inverter with low voltage (48 V) and 2 MPPT, designed to maximize self-consumption and enable fast UPS-type backup for critical household loads. It features export control, BMS communications, and cloud monitoring, ensuring quick commissioning and efficient operation.

Key Features

• 2× MPPT architecture (1 string/MPPT) for different orientations.
• LV 48 V battery (LiFePO4/LFP) with BMS via CAN.
• Backup <10 ms for continuity on essential circuits.
• Export control (zero export or configurable limit).
• IP65, convection cooling, and silent operation.
• Integrated protections (anti-islanding, SPD, insulation monitoring).

Main Electrical Data

• Topology: single-phase 230 V; 50/60 Hz; adjustable PF.
• PV inputs: 2 MPPT; wide stable operating range.
• Battery: 48 V LV with bidirectional charge/discharge management.
• Back-up: dedicated output for critical loads (<10 ms).
• Export control: via external meter through RS485.

Communications and Monitoring

• With BMS: CAN (compatible with standard 48 V LFP banks).
• With meter: RS485 (GoodWe) for zero or limited export.
• GoodWe Portal/App for commissioning, O&M, and diagnostics.

Installation and O&M

• Wall mounting, integrated DC isolator, and clear wiring.
• Commissioning assistant via app; upgradable firmware.
• Fanless design: lower maintenance and reduced noise level.

Dimensions and Weight

• Dimensions (W × H × D): N/A
• Weight: N/A

Recommended Applications

• Homes with photovoltaic installations prioritizing self-consumption.
• Users requiring continuity on essential circuits (backup).

Note for installers: Size the PV array and 48 V LV battery bank according to consumption profile; configure power factor, time-of-use modes, and export limit according to local regulations. Verify compatibility and firmware of the selected BMS.
