Is It Ok To Install Photovoltaic Power Without Energy Storage Battery
2025-07-02
Bonada will tell you that it is OK, but there are also situations where it is not OK. Why?
When the installed photovoltaic power exceeds the load power consumption with no energy storage battery, there will be excess photovoltaic power and a large amount of excess photovoltaic power will be produced and sent to the power grid.
If it is a situation of going online with surplus power, it is OK; if is self-generated or self-consumed generation, the backflow device at this point will affect the conversion efficiency of the inverter, and may even burn out.
More importantly, it will also be affected by the weather environment. On low solar irradiance days, you can experience cloudy days or rain days, and the photovoltaic power generation will be reduced to a very low level. At this point, if we have an energy storage battery cabinet, we can charge energy storage during off- peak times, to use.
Moving forward, when we have insufficient photovoltaic power generation during the day, we will be in peak demand period, and we can use then energy of our storage battery cabinet and obtain the maximum benefit or saving further electricity bills. This combination is nice for the factory energy consumption. Do you understand?

Electricity is one of the largest operating expenses for many factories. The problem is not always the total amount of electricity a facility consumes. In many markets, a factory can face significantly higher charges simply because its power demand reaches a high level for a short period.
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.
