Portable energy as an alternative to traditional generators - Wattsun develops innovative, portable, and sustainable battery systems for companies operating in locations without access to a fixed power supply. With Wattsun’s plug-and-play energy systems, professionals can work emission-free, quietly, safely, and independently - exactly where access to the electricity grid is unavailable.
Energy at any location, without a generator
At construction sites, events, film sets, or temporary work locations, electricity is essential but often unavailable. Traditional generators cause emissions, noise pollution, and high maintenance costs. Wattsun offers a clean and efficient solution: mobile battery modules that provide power easily wherever and whenever it is needed.
The Wattsun Battery System
The Wattsun system consists of modular, stackable battery units:
- Wattsun Dock; the base station and power supply unit
- Wattsun Pack: additional battery modules for increased capacity
- Wattsun Dock+: an advanced version with extended charging capabilities
Thanks to the intelligent Battery Management System (BMS), the modules are easy to operate, even without technical knowledge. The units are robust, splash-proof, and ergonomically designed for safe transport.
Wattsun Dock+ for maximum flexibility
The Wattsun Dock+ is an advanced portable battery solution that supports charging via mains power, solar panels, wind energy, or vehicle power (9–48 V DC), even while driving. Simultaneous charging and discharging during operation is also possible.
Using the Wattsun Charger 600, a stack consisting of one Dock+ and two Packs can be fully charged within approximately 2.5 hours.
The benefits
The Wattsun Dock and Wattsun Pack are designed for maximum ease of use. Thanks to the intuitive design and simple operation, anyone can create a reliable power source, even without technical expertise.
The robust and splash-proof housing makes the system ideal for demanding on-site environments.
