Project Overview
This project is located in Spain. The photovoltaic storage system comprises a 30KW photovoltaic inverter and an 86KWh energy storage battery, forming an off-grid photovoltaic storage system. It is equipped with nine 550W photovoltaic panels. The system meets the client’s current requirement for no mains electricity supply, while also incorporating a hybrid grid-tied/off-grid mode to accommodate future mains electricity connection needs.

Applications
Off-Grid Standby Mode: During mains power outages or absence, the photovoltaic system supplies loads and charges the storage batteries when operational. When PV generation is insufficient or unavailable, the storage batteries power loads until battery capacity falls below 10%, at which point the system enters standby or shutdown mode until PV generation resumes.
Grid-Connected Hybrid Mode (Reserved Functionality): A backflow prevention device is installed on the AC input side of the PV inverter to enable grid connection of the PV generation. In this mode, the system connects to the grid when mains power is available, ensuring priority use of PV power for self-consumption. Future upgrades will enable the sale of surplus PV electricity to the grid as required.
