Main Features
- Nominal AC power: 4 kW with maximum output capacity of ~4.4 kW (110%).
- 2 independent MPPTs to optimize two different roof slopes or inclinations.
- MPPT window: 180–850 Vdc; maximum input voltage 1000 Vdc; startup at 180–200 V.
- Current per MPPT up to 16 A (max Isc 20 A); 1 string per MPPT.
- Maximum efficiency 98.2% and European efficiency ~97.6% for higher annual yield.
- IP65 enclosure and fanless design for silent operation and lower OPEX.
Advantages or Benefits
- More energy and lower return on investment thanks to its high efficiency and management of two orientations.
- Easy installation: lightweight chassis, MC4 connectors, and pluggable AC terminals.
- Integrated safety: DC isolator, RCMU, insulation check, and SPD Type III (Type II optional).
- Monitoring and control: RS-485 (Modbus-RTU), optional Wi-Fi/LAN, and Goodwe SEMS portal.
