Need more battery capacity for your power needs? Stack a Wattsun Pack on a Wattsun Dock. The intelligent control system takes care of the rest. Stack up to four Packs on a Dock to create a power supply of up to 11 kWh.

  • Charge anytime, anywhere - Charge the Wattsun Dock directly with solar panels or wind energy. Charging from the power grid is also an option.

  • Portable - The Dock is easy and safe to move thanks to its light weight (<19kg) and ergonomic handles. Lift our battery system with two hands, or with one hand using the carry strap, leaving your other hand free.

  • Generate, store and use - Generate energy, store it immediately, and use power on-site either simultaneously or later. With the Dock, you'll always be self-sufficient. Wherever you are.

  • Built-in fast charger - The Dock is fully charged in approximately 3 hours thanks to the built-in fast charger. Charge the Dock from the power grid (820W) or with solar panels (1400W).

  • UPS - Use the Dock as a backup power supply. Connect your device to the Dock and plug the charging cable into the power grid. In case of a power outage, the Dock will immediately switch to battery power.

  • Charging in stack - The Dock allows you to charge a complete stack of Wattsun modules. Plug the charging cable into the Dock, and the intelligent control system will automatically charge the stack from bottom to top.

  • >1000 cycles The lithium-ion battery cells in the Dock are of the highest quality, ensuring a long lifespan of over a thousand cycles.

  • Always the right connection - Our products are compatible with all international types of sockets, wherever you are. Contact us if you need a specific international standard.
