Do I Need Solar Panels or Inverter For Battery Energy Storage System (BESS)?

Battery energy storage systems (BESS) can be charged in a variety of ways, including from the grid or from renewable energy sources such as wind or solar power. If you have access to a reliable and affordable source of renewable energy, such as a solar panel system, then it can be a great way to charge your battery storage system.

However, even if you don't have a solar panel system, a battery energy storage system can still be useful. It can provide backup power in case of a power outage or can help you save money by charging during off-peak hours when electricity rates are lower and then using the stored energy during peak hours when rates are higher.

To have a functional battery energy storage system, you will need an inverter, but you do not necessarily need solar panels.

The inverter is an essential component of any battery energy storage system, as it converts the direct current (DC) energy stored in the batteries into alternating current (AC) energy that can be used to power your home or business.

If you have solar panels, then you will also need a solar inverter to convert the DC energy produced by the panels into AC energy that can be used in your home or business. However, if you do not have solar panels, you can still use an inverter to charge your battery energy storage system from the grid or from other renewable energy sources such as wind turbines.

So, while you do not necessarily need solar panels for a battery energy storage system, you will need an inverter to make use of the stored energy. If you also have solar panels, you will need a solar inverter as well to convert the DC energy produced by the panels into usable AC energy.
