PV Powerstation – Smart Energy Storage for Balcony Power Plants (1–6 kWh)
The PV Powerstation is a modular, stackable
PV energy storage for balcony power plants, which can be used both as a stationary system and
POWERHub can also be used as a portable POWERBox.
Thanks to safe LiFePO4 (LFP) technology, intelligent
energy management, and high compatibility, the system is ideal for
PV modules, micro-inverters, and hybrid wind and solar applications.

Stationary or mobile – maximum flexibility
With the POWERHub, the battery is operated in stationary mode and
is connected directly between the PV modules and the micro-inverter.
For mobile applications, remove the hub and attach the POWERBox
—ideal for camping, the garden, the workshop, or emergency power.
The Safest Battery Technology – LFP
The CATL Class A cells used offer the highest level of safety
. According to a VDE study, LFP batteries do not experience thermal runaway
and are considered“unmatched in terms of safety.”
Compatible with POWERFence
For optimal performance, connect the POWERFence to the actuator in a 2-series configuration (39.6 V)
. All standard microinverters are compatible.
With the PV Powerstation, you get a flexible, safe
, and high-performance storage system for balcony power plants, hybrid systems, and
mobile applications—ready to use right away and expandable.
