Balcony Power Plant with Storage 1500W - Ja Solar 500W Solar Panels with EcoFlow STREAM Ultra X

Balcony Power Plant 1500 Wp – 3 Modules + EcoFlow STREAM Ultra X 3.84 kWh

Three high-performance JA Solar 500 Wp glass-glass modules together deliver up to 1500 Wp DC power. The EcoFlow STREAM Ultra X stores 3.84 kWh for later use. Ideal for generating solar power during the day and using it efficiently in the evening – without the need for an electrician or complicated technology.

Why a 1500 Wp Balcony Power Plant with Storage?

• Self-consumption > 95 %
PV yield charges the battery during the day, and in the evening, the solar bank provides up to 1200 W AC power.

• Plug & Play
Simple connection of the solar bank between module and socket – plug in Schuko, done.

• Modularly expandable
Connect up to 6 expansion batteries – total capacity up to 23 kWh.

• Legally flexible
AC power can be limited to 800 W via app – for compliant operation in Germany.

• Emergency power capable
In island mode, the system supplies routers, lights, and cooling devices during a power outage.
