What is a battery energy storage system?
A battery energy storage system (BESS) plays a vital role in balancing renewable energy’s intermittency during peaks of demand for electricity. It stores excess energy generated by sources such as solar power and wind during periods of low demand and releases it when needed — ensuring grid stability and preventing outages.
Why should we invest in battery energy storage systems?
As the world continues to invest in clean, resilient energy systems, BESS will remain at the forefront, helping to build a more sustainable future for everyone. Despite its benefits, deploying battery energy storage systems presents several challenges. A key issue is battery degradation over time, particularly for lithium-ion batteries.
Why is battery storage important?
As we shift toward clean energy, battery storage systems have become key to integrating renewables into the grid. 1 By smoothing out the energy supply from intermittent renewable sources, BESS enhances grid reliability, reduces reliance on fossil fuels and helps lower carbon emissions, making it a crucial player in the energy transition.
How much energy will be stored in a battery system?
Looking ahead, a sixfold increase in global energy storage capacity is needed by 2030, with 1,200 GW expected to come from battery systems, to meet climate and energy goals. 8 Reducing emissions: BESS optimises the use of renewables by storing excess energy, reducing the need for fossil fuel power generation.
In simple terms, wiring batteries in series raises the system voltage but keeps the amp-hour (Ah) the same, while wiring in parallel keeps the voltage the same but increases total capacity, so your choice should always start from “do I need higher voltage or longer runtime?”

Should you connect a battery to an inverter in parallel?
Many people prefer to connect batteries and inverters in parallel. This is because there is less limitation on how many batteries you can connect to your inverter at once. The other thing to consider is your battery charger. The bigger your battery capacity and overall amperage, the more powerful your battery charger needs to be.
Should Inverter Batteries be wired in series?
If you decide to wire your inverter batteries in series it will increase the voltage and limit how many you can hook up to your inverter. Many people prefer to connect batteries and inverters in parallel. This is because there is less limitation on how many batteries you can connect to your inverter at once.
Can you connect a battery in parallel?
Connecting batteries in series increases the voltage (V), while connecting them in parallel increases the capacity (amp-hours, Ah). The total power (measured in watt-hours, Wh) available from the batteries remains the same in both configurations; it’s the delivery—voltage and current—that differs. Can you wire different batteries in parallel?
What is the difference between a series and a parallel battery?
Batteries wired in series will add their voltages while the current capacity stays the same. Conversely, batteries wired in parallel will have their current capacities added together while their voltage remains the same.
For outdoor installations, it's crucial to choose a battery system, like EP Cube, with weatherproof housing that can withstand rain, snow, dust, and other environmental elements. Look for a battery with an IP rating that signifies its level of protection against dust and water. .
