A guide to battery energy storage system components

Battery energy storage system for wind and solar energy

What is a battery energy storage system?

Different energy storage systems include thermal and mechanical systems, such as pumped hydro power. Hydroelectric power storage is by far the most common form of stored energy, but harnessing it depends on finding sites with upper and lower pools. That leads us to the most common power storage device: batteries.

Battery storage systems are an important renewable energy-storage technology. They integrate solar or wind renewables in power systems all over the U.S. Off-grid energy storage relies on batteries and enables users to be 100% self-sufficient. Grid storage solutions allow users to sell back the energy to their power companies for credits and use inverters instead of batteries. However, some grid energy storage systems add batteries, creating a hybrid system so that even during blackouts, users have energy.

Battery storage for solar and wind must perform at optimum level to be effective. These energy storage systems must react right away to changing demands, the rate of energy lost in the storage process, the capacity of storage, and the recharging speed.

In order to do those things, your indoor cabinets or outdoor enclosures must be able to withstand extreme environments and harsh temperatures to prevent equipment failure. Cable management, fasteners, access hardware – all the small components you’ll need for your power storage solutions need to be robust and durable while resisting corrosion, harsh temperatures and tampering.

Battery energy storage systems and containers

Battery energy storage storage systems and containers

Whether you’re designing for residential or industrial battery storage, you’ll not only use a battery, but also monitoring and control systems and a power-conversion system. We recommend you use these battery energy storage system components:

Monitoring and control systems for energy storage

Monitoring and control systems for energy storage

You’ll need to think about your renewable energy storage device that monitors and controls the generation and consumption of energy. To maximize performance, use high-quality components as part of your battery management system (BMS). This will help dispatch the battery’s power at optimal efficiency.

​PCB standoffs – hexagonal/insulator

Solar panels and energy storage containes

Power conversion system

Grid storage systems and off-grid energy storage systems – also called microgrids – need to convert wind or solar panel energy into power. For example, an inverter for a solar panel system or wind turbine converts the direct current (DC) into ready-to-use alternating current (AC) to feed the grid. Some of the components you’ll need for your system will include the same PCB hardware as your monitoring and control system uses, along with:
