Multiple, swappable battery modules prevent an entire energy storage unit from going down if one battery module fails. The module can be swapped out for another with no downtime.
Sensors ensure safe operation and allow for remote monitoring. Onboard sensors help maintain appropriate operating temperatures, watch for battery module failure, and report usage data to you and your energy company.
Control components mean energy storage systems can be set up however they need to be to perform their intended job without any ongoing user intervention. For example, batteries can be configured to charge automatically when energy is cheapest and discharge automatically when it’s most expensive, or they can be configured to simply store energy in case of a power outage.
Integrated inverters make installation easy and inexpensive. 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 Tesla’s Powerwall 2, have more capabilities, work without solar arrays, and are easier to install. Modern systems simply plug into an existing power network.
Best-in-class energy storage systems – have a few more key components: built-in cooling systems, weatherproof construction, and scalable architecture.
Built-in cooling ensures optimal performance. Weatherproof construction means energy storage systems can be mounted outside without the added cost of protective structures. Scalable architecture means multiple energy storage units can be linked to form a larger system. Additional units can always be added later.
Taken together, these components make battery energy storage systems safe, scalable, and cost-effective.
