When selecting an energy storage system, it is crucial that the battery meets technical requirements such as compatibility, warranties, cycle life, and features. However, this post focuses on the other side of the coin—highlighting aspects such as flexibility, adaptability, and installation time.
Choosing the right battery involves considering multiple factors. Let’s start with placement. Traditional energy storage systems without heating capabilities must be installed indoors, as standard LFP batteries have a limited temperature range in which they can operate at full capacity. One of the built-in advantages of qapasity’s batteries is their integrated heating system and the latest semi-solid-state technology, which allows them to be installed both indoors and outdoors.
All qapasity semi-solid-state batteries come equipped with quick connectors, which simplify installation by integrating power and communication connections in one step. When stacking battery modules, the quick connector automatically links the positive, negative, and communication cables—meaning no internal wiring is required, as the battery is fully pre-configured from the factory.
When deciding on the right storage capacity, several factors must be considered, depending on the intended application of the battery. As a buyer, ensuring that the system is future-proof and adaptable to evolving needs is essential. This means the system should be flexible enough to start small or large and allow for future expansions. With qapasity’s modular battery system, you can configure between 2 and 7 battery modules, providing a capacity range from 10.84 kWh to 37.94 kWh. Many systems on the market are limited to around 15 kWh in a single “battery tower,” but qapasity’s standard design exceeds this capacity.
Expanding your battery system in the future can be done in two ways. First, by adding new battery modules to the existing stack, provided the system is no older than approximately two years to avoid potential issues caused by mixing older and newer modules. The second option is to connect an identical battery tower in parallel, effectively doubling the total battery capacity without the risk of compatibility issues between different module ages.
