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 UK. 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 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:

Battery energy storage
​Sealing gaskets

Sealing gaskets

Poorly sealed containers and enclosures for wind solar battery storage can create a hazard. Use clip-on profiles to provide edge protection and sealing. Essentially used on metal sheet, they offer protection from vibrations, ingress of humidity and dirt. Different styles available in EPDM and PVC. Also available: weather-stripping tape, also known as adhesive gasketing, for great barrier protection from moisture and air.

​Screw/weld-on concealed hinges

Screw/weld-on concealed hinges

The hinge is not visible from the outside, offering greater security by hindering vandalism. Left-hand and right-hand applicable. Ideal for metal enclosures. Different types and styles available. Your choice of steel or stainless steel.

​Machine screws – cheese

Machine screws – cheese

Slotted cheese head machine screws are an excellent replacement for all metal screws. A lightweight option, they’re resistant to vibration, chemicals, electricity and corrosion, protecting the integrity of containers for industrial battery banks, solar power battery storage and wind turbine energy storage applications. Nylon 6/6.

​Plastic hex nuts

Plastic hex nuts

The hexagonal shape provides an easy way to tighten and loosen this nut with a standard wrench. Plastic hex nuts are non-conductive, corrosion resistant and provide a lasting hold. Also available in polycarbonate, nylon 6/6, PEEK®, PVDF and PP. You might also consider plastic wing nuts.

​Stud mount levelling feet – plastic swivel base

Stud mount levelling feet – plastic swivel base

Adjusts to uneven surfaces and levels stationary energy storage systems. Articulating swivel and large diameter pads of these adjustable feet provide solid levelling and support. Polypropylene.

Monitoring and control systems for energy storage

Monitoring and control systems

You’ll need to think about your renewable energy storage device that monitors and controls the generation and consumption of energy. To maximise 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

PCB standoffs – hexagonal/insulator

Male/female standoffs are designed to be installed by hand. No assembly equipment needed. These hexagonal standoffs are ideal for your renewable energy storage BMS, providing high-mechanical strength and sturdy, insulated spacing. Operating temperature range: -40˚C to 85˚C. UL94 V-2. Nylon with brass inserts.

​PCB support posts

Rated IP30 to protect the fan of your BMS against the insertion of tools. Includes one each of finger guard, fan filter cover, fan filter mesh sheet and felt filter. Ideal for solar panel battery storage or wind energy storage applications.

​Fan gaskets

Fan gaskets

Reduce vibration generated by air leakage between the fan and chassis. These fan gaskets protect DC and AC fans suitable for your power storage technology by providing a seal between the fan and the mounting bracket. Operating temperature range: -70˚C to 150˚C. Silicone rubber.

​Metal fan guards

Prevent debris falling into the fan blades and causing an obstruction. Ideal for protecting the monitoring and control systems of your power storage solution. Simple to install with screw mount application. Steel.

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:

​Cable ducts

Cable ducts

Ideal for wiring panels and energy storage systems. Holds breakout wires while providing flexibility for adding or removing wires. Available as screw mount or self-adhesive mounting. UL94 V-0. PVC or PP.

​Cam latches – lift and turn

Cam latches – lift and turn

Also known as swing handles. Low profile handle stows away when not in use. Consists of a slam-action spring-loaded handle and can be used either indoors or outdoors. Ideal for solar or wind energy storage systems that house electronics and wiring, such as enclosures for inverters. Available with a choice of keyed alike, key to differ or a button to press.

Plastic flat washers
