Important notice for our customers in Belgium: An environmental contribution of € 109.82 excluding VAT will be applied to the purchase of each BYD-Box Premium HVS lithium battery. More information at the bottom of the page. |
Off-grid applications and backup power capabilities are no problem for the Battery-Box. The high discharge capacity allows operation disconnected from the power grid. Whether the project supplies electricity to an isolated hut or is used as a backup system for sensitive loads, BYD has the storage you need.
Self-consumption of renewable energy is the future. As subsidies for renewable energy production decrease around the world and electricity prices rise, it becomes more economical to consume the energy you produce yourself.
From single-family home to commercial applications, if you can design it, you can use the Battery-Box to build it. As an installer, you want to work with the same common building block but adapt it to the needs of your customers. You can even start small and add capacity at any time during the life of the product.
BYD's cobalt-free lithium-iron-phosphate (LFP) battery ensures maximum safety, service life and power. Robust chemistry and universal design can operate in a wide range of temperatures and areas around the world.

A Premium HVS Battery-Box is composed of 2 to 5 HVS battery modules that are connected in series to reach
a useful capacity of 5.1 to 12.8 kWh.
In addition, the direct parallel connection of up to 3 identical Premium HVS Battery-Boxes allows a maximum capacity of 38.4 kWh. Ability to scale by adding parallel HVS modules or HVS stacks later.
