Sunwoda battery module for the SunESS-H 5kWh high-voltage set

Sunwoda SunESS-H 5 kWh module This is a component of a high-voltage energy storage system based on LiFePO4 technology, designed for operation in sets from 5 to 60 kWh. The module’s nominal energy is 5 kWh, and the system voltage is approximately 409.6 V; the device offers a high efficiency factor (>95%) and can work both as part of a hybrid PV-inverter system and in battery-only mode. The module is equipped with quick connectors, CAN/RS485 interfaces, WiFi/LAN options, and built-in protective functions (surge, overload, thermal, and others).

The SunESS-H system is scalable — up to three modules in standard parallel connection (max. 60 kWh in configurations) — and can operate in outdoor or indoor mode; the design allows mounting with outdoor suitability (IP55) and natural cooling. Battery status, SOC, and alarm monitoring functions are included.
