Why Must Photovoltaic Off-Grid Be Equipped With Energy Storage Battery
2025-07-02
Bonada tells you that because in the off-grid state, if there is excess photovoltaic power, it cannot be sent to the grid, otherwise it will involve fines from the power supply bureau. But how to deal with the excess power? At this time, equipping with energy storage batteries can solve this problem - this part of the excess power can be stored in the energy storage battery cabinet.
Doing so can not only improve the power generation efficiency of the inverter, but also avoid damage to the line. At the same time, after storing the excess power in the energy storage battery cabinet, it can be used when needed in the afternoon, etc., to increase the value of photovoltaic power generation.
In addition, if DC energy storage is used, the maximum power of photovoltaic power generation can be limited according to the power generation situation. When the power generation is excess or insufficient, the photovoltaic power generation can be controlled, and it can be equipped with an anti-backflow system. The system communicates with the EMS system and can accurately achieve anti-backflow, so that you can avoid being fined by the power supply bureau for sending electricity to the grid.

129kWh BESS Cabinet: Complete Guide to Capacity, Components, Applications and Sizing
One of the first questions homeowners ask when considering solar storage or backup power is: How many batteries to run a whole house? It sounds like a simple question, but the answer is different for every home. A battery system that works well for a small house with basic backup needs may not be enough for a larger property running air conditioning, electric heating, or an EV charger.

A typical 129kWh BESS cabinet contains much more than battery cells. Inside the enclosure, multiple systems work together, including battery modules, Battery Management System (BMS), high-voltage protection units, Energy Management System (EMS), cooling equipment, fire protection devices, and communication components. Each part has a specific role in maintaining safe and stable energy storage operation.
