WattCycle is bringing a 10 kWh balcony solar storage system to Intersolar Europe in Munich next week, aiming at the German market where apartment-dwellers are the fastest-growing segment of residential solar buyers.
The Shenzhen-based company, which has 16 years in energy storage, will show the all-in-one unit at Booth C4.251 in Hall C4 from June 23-25. The system stores up to 10 kWh and offers bidirectional power at 2.5 kW or 5 kW. That capacity is high for a balcony setup – most plug-in balcony systems in Germany max out at 800 W inverter output under current regulations, though the 5 kW option suggests WattCycle is positioning for a rule change or for off-grid use.
The unit runs on a plug-and-play design with an integrated microinverter interface and an AC charging port. Users can charge from the grid during low-tariff periods and discharge when prices rise. An AI-based scheduler automates the cycle.
