- 100% self-consumption
- Electricity costs 0.1 CHF/kWh
- Emergency power with full performance without interruption
Project Details
This project is not just about technology—it is about trust and quality. The products are developed and produced with precision in Switzerland and they guarantee top-notch engineering. With a commitment to quality, Dr. Daniel Bächi personally guarantees the excellence of the products and services. Every day, 24/7, 365 days a year, the system ensures reliable performance. The focus on real-life benefits has inspired energy solutions that relieve the grid and address common issues of energy pricing and throttling by utilities. In fact, this innovative system enables utilizing stored power after sunset and even supports existing photovoltaic setups. Battery storage containing 4 hours or more of production enables households to enjoy 1-3 days of (emergency) power, avoiding the hassle of selling electricity at low prices during the day and repurchasing it at higher rates at night… a pragmatic solution for saving on costs.
Technology & Innovation
The project leverages cutting-edge 50V technology, an approach that ensures lower costs and excellent compatibility. This advanced technology not only makes the system economical but also one of the safest solutions available. The 50V batteries are touch-safe, eliminating any arc risk, and the overall design is flexible and easily expandable. With a lifespan of 20 years, each cell can be replaced individually without compromising the system’s integrity. Such technological sophistication demonstrates how innovation is embedded throughout the project to deliver superior energy management and safety.
Additional Offerings
Beyond the flagship POWER BOX STORAGE SYSTEM, the project extends its expertise across a range of products. The POWER BOX accommodates multiple battery types including Lithium Iron Phosphate (LFP), sodium (salt), or even second-life cells, with guidelines available on how to integrate them effectively into any existing setup. Complementary products include the EMASTER system designed for monitoring independent of cloud services—a crucial feature for those who prefer data control without third-party oversight. Also available is the EMASTER2, a load manager that enables 1-9 vehicles to charge from a single 11kW connection via the E-CHARGING SYSTEM EVSE-WLAN. The hybrid inverter facilitates the delivery of power during outages, ensuring buildings remain operational even in emergencies. Additionally, a MOBILE POWER solution provides energy on the go for a multitude of applications, from induction cookers to electric coffee machines, and can serve as a battery module for vehicle propulsion. Custom batteries, complete with BMS, balancer, inverter, and display, are also developed to meet unique energy demands.
