Specifications
Product description
The GoodWe GW3048-EM 3kW 48V Single-Phase Hybrid Inverter is a low-voltage residential hybrid that combines photovoltaic generation, 48 V battery storage, and instant backup for critical loads. With IP65 enclosure, silent fanless design, and WiFi connectivity, it integrates all the functions needed for reliable self-consumption: zero export with RS485 meter, intelligent energy flow management, and UPS-type switching <10 ms to ensure continuity when the grid fails.
Main features
- Nominal on-grid AC power: 3 kVA (230 V, 50/60 Hz); dedicated backup output up to 2.3 kVA (3.5 kVA 10 s).
- Hybrid LV architecture (48 V) with battery charge/discharge up to 50 A and management via CAN/RS485.
- 1 MPPT with range 100–500 Vdc (startup 125 V), max Vdc 550 V, current per MPPT 11 A.
- Maximum efficiency ≈97.6% (EU ≈97%); battery↔AC performance ≈94.5%.
- Integrated protections: anti-islanding, type III DC/AC SPD, insulation detection, and DC isolator.
- Communication: WiFi (SEMS Portal), optional RS485/LAN for wired integration.
Advantages or benefits
- True autonomy: maintains lighting, router, or IT equipment thanks to backup <10 ms.
- Optimized savings: prioritizes consumption, stores surplus, and limits export to comply with regulations.
- Silent and compact: fanless, ideal for installation near inhabited areas.
- Scalable: allows expansion of PV power (up to 3.9 kWdc) and battery capacity tailored to the project.
- Total control: remote monitoring and simple configuration via app.
Purpose or applications
Designed for single-family homes and small businesses with moderate base demand seeking energy security, bill reduction, and service continuity during brief outages. Suitable for residential installations with a single phase and 48 V battery banks.
