Hey, How can we help you?

Energy storage is important on an industrial or grid scale for three main reasons. The first is to "balance load" — to shift energy consumption into the future, often by several hours, so that more existing generating capacity can be used efficiently. The second reason is to "bridge" power — in other words, to ensure uninterrupted service during the seconds-to-minutes required to switch between different power generation sources. Finally, power quality management — the control of voltage and frequency to avoid damaging sensitive equipment — is an increasing concern that storage can alleviate whenever needed, for a few seconds or less, multiple times throughout day. 

Residential energy storage refers to energy storage systems installed in homes or small residential properties. These systems typically store excess energy generated from renewable sources like solar panels and provide backup power during outages or when the demand exceeds the supply.

On the other hand, commercial energy storage involves larger-scale energy storage solutions designed for commercial or industrial settings. These systems can store a significant amount of energy and are often used by businesses to manage peak demand, reduce energy costs, and enhance electricity stability.

Battery storage enables greater self-consumption of renewable energy from variable sources like solar power. Businesses that face difficulties in the reliability or capacity of their electricity supply can reap benefits from battery storage. Battery storage can also save on power costs by reducing the need to purchase electricity during expensive periods.

Yes, storage can contribute to local energy security and energy resilience, especially when the batteries are paired with local power source on a community microgrid. A microgrid is a small network of customers with a local source of electricity that can be disconnected from the grid and operated independently.

During and after natural disasters and extreme weather events, all of which are becoming more frequent due to climate change, battery storage can help keep essential services running and protect the most vulnerable populations as part of a community-driven climate resilience plan. When thinking about community resilience, it can be advantageous for critical infrastructure — such as police and fire stations, hospitals, cooling centers, and emergency shelters — to have rooftop solar panels and battery storage systems on site to keep the power on during an emergency.

AlphaESS only uses Lithium Iron Phosphate (LFP) cells, which are safer than the lithium batteries used in cars. The chemical composition of LFP cells virtually eliminates the risk of overheating and thermal runaway, making them safe and non-flammable even in extreme conditions. LFP cells also have a long lifespan. Although they are slightly heavier and less compact, this is usually not a problem in a domestic situation. An additional advantage is that the LFP cells do not contain any cobalt.
