The red alarm on the Sofar HYD3000-ES indicates a fault or error condition. Possible causes include battery overvoltage (ID05), grid LVRT fault (ID07), PV voltage too high (ID08), internal faults (ID09-ID26, ID53-ID55), insulation resistance too low (ID56), or overheating issues (ID57-ID59). The appropriate action depends on the specific fault code displayed.
1. HYD-ES inverter Introduction The HYD-ES hybrid inverter is used in PV system with battery storage. Energy produced by the PV system will be optimized for maximum self-consumption. The HYD-ES inverter can work in auto or time-of-use (TOU) mode, charge / discharge the battery when needed. In auto mode, the HYD-ES inverter will charge surplus PV energy into the battery &...
2. Safety Notes Before installation, please make sure you read & understand this manual. The HYD-ES inverter strictly comply with safety rules of design and testing. During the installation, operation and maintenance, operators should abide by local safety regulations. Improper operation may cause an electric shock or damage the equipment and properties. 2.1.
Battery maintenance operators shall have the knowledge and technical skill for battery maintenance; All batteries connected in parallel should be of the same model and have same firmware version. This is a design issue needs to be considered by designer/installer, particularly when replacing batteries or modifying an existing energy storage system.
