Economic efficiency and amortization
- (1) PV installation with 1.8 kW and battery storage of 4.8 kWh (2x B2400): annual production approx. 1860 kWh, payback period 3.8 years.
- (2) Due to better solar radiation in summer and less in winter, it is recommended to slightly increase the storage capacity (2–3x B4800) in order to store more electricity in summer and achieve additional profits in winter with dynamic electricity tariffs.
- (3) For AC coupling (AC charging) without PV investment, the payback period is less than 2 years.
- (4) Maximising self-consumption through smart electricity meters and reading heads to maximise economic benefits.
Easy installation and plug & play (DIY-friendly)
- (1) Installation completed in just 15 minutes.
- (2) Stackable, no complex cabling required.
- (3) Easy connection to a conventional household socket.
- (4) Integration of existing balcony inverters via the off-grid port for AC coupling.
- (5) Wireless WiFi communication with smart meters, no communication cables needed.
- (6) Three-phase parallel operation for extended DIY use.
Grid compatibility (backfeed protection) and safety
- (1) Smart electricity meters and reading heads for backfeed protection according to German grid requirements.
- (2) Feed-in can be controlled via app.
- (3) Fast response (<1 second) to prevent backfeed.
- (4) Island operation function: In case of mains failure, the mains output is automatically switched off, off-grid output can still be used (2400 W).
- (5) Secure hardware through BMS and aerosol protection.
- (6) Battery cycle count 800, batteries suitable for low temperatures (charging and discharging at -20°C).
Intelligent energy management (AI optimization and self-learning)
- (1) Automatic optimization of the charging/discharging strategy to increase yield and battery safety.
- (2) Optimal operating strategies based on load profiles and PV yield forecasts.
- (3) Supporting dynamic electricity prices to optimize revenue.
- (4) Cloud-edge cooperation for off-grid local control and optimization of smart devices (e.g. e-charging stations, heaters).
- (5) Connection to smart home platforms (e.g. Home Assistant).
- (6) Load control using smart sockets based on dynamic electricity prices.
Ecological compatibility
- (1) Compatible with electricity meters and reading heads from brands such as shelly, everHome, Tibber and homewizard.
- (2) Integration of heating elements, e-charging stations and power controls (e.g. MYPV) to create a home microgrid.
- (3) Connection to smart home platforms (HA, everHome) for harmonious integration into the household ecosystem.
- (4) Support for dynamic electricity pricing in 18 countries and 26 regions.
