Each energy storage unit contains several components: one or more battery modules, integrated sensors, control components, and an inverter. On DC coupled units, a separate inverter is used. On AC coupled units, the inverter is built into the system. These components make energy storage systems more than just batteries.
Multiple swappable battery modules prevent an entire energy storage unit from shutting down if one battery module fails. The module can be exchanged for another without downtime.
Sensors ensure safe operation and enable remote monitoring. Built-in sensors help maintain proper operating temperatures, monitor for battery module failures, and report usage data to you and your power company.
Control components mean that energy storage systems can be configured as required to do their intended job without any ongoing user intervention. For example, batteries can be set to automatically charge when power is cheapest and automatically discharge when power is most expensive, or they can be set to simply store power in the event of a power outage.
Integrated inverters make installation easy and economical. While DC-coupled battery storage systems with separate inverters can be cheap, efficient, and good for off-grid homes, they offer much less flexibility than AC-coupled units with integrated inverters. AC-coupled units, like the Tesla Powerwall 2, have more capabilities, work without solar panels, and are easier to install. Modern systems simply plug into an existing power grid.
Best-in-class energy storage systems like the ones we offer have a few more key components: built-in cooling systems, weather-resistant construction, and scalable architecture.
Integrated cooling ensures optimal performance. Weatherproof construction means energy storage systems can be mounted outside without the added cost of protective structures. The scalable architecture means multiple energy storage units can be linked together to form a larger system. Additional units can always be added later.
Together, these components make Containerized Battery Energy Storage systems safe, scalable, and cost-effective.
