GoodWe ES Series 5kW Single Phase Hybrid Inverter
Product Overview
The GoodWe ES series of bi-directional energy storage inverters are designed for both on-grid and off-grid photovoltaic (PV) systems, offering intelligent control over energy flow. During daylight hours, the PV array generates electricity that can power local loads, feed into the grid, or charge the battery, based on system economics and configuration. Stored energy can be discharged during nighttime to meet load requirements, including inductive loads like air conditioners or refrigerators. The power grid can also be utilized to charge storage devices through the inverter. This system provides comprehensive intelligent energy management for maximum flexibility.
Key Features:
- ⚡️ Charge controller and inverter integrated
- ? Export control (Zero export)
- ⏱️ 8 ms UPS-level Switching
- ? Maximum charge and discharge up to 100A
- ?️ IP65 dustproof and waterproof
- ?️ Fanless design, long lifespan
The product is a compact, white inverter unit with multiple connection terminals at the bottom, designed for wall mounting.
