Are You Ready To Unleash Your Balcony Power?



1. What is BigBlue POWAFREE Balcony Solar?

POWAFREE Balcony Solar is more than just a power station. You are getting a compact energy storage system - a combo of a PV controller, battery system, and flexible solar panels.

Homes with the POWAFREE installed rely less on the grid by capturing free power directly from the sun. Homeowners can take control and offset their power usage with solar panels and reduce their electric bills. Alternatively, you can use POWAFREE to store the excess generated power during the day (when you are at work) and use this stored power at night, which would enable you to achieve self-generate, self-consumption, and self-sustainable power.

NOTE: This product cannot be used during power outages.

2. I am new to solar-powered, how do I configure POWAFREE Balcony Solar as my balcony power storage system?

BigBlue has streamlined the design and installation process to be incredibly easy to install, even for new entrants. No complicated wiring. Just plug-and-play!

NOTE: Check the local regulation on the upper limit allowed for solar system installation. If you are from the Europe region, the standard is 800W whereas some countries would be 600W (but POWAFREE caters both). You don't need to register with an operator as opposed to just the traditional roof- or ground-mounted solar systems.

3. Can the POWAFREE Balcony Solar operate in the wintertime?

Thanks to the revolutionary and ground-breaking BigBlue's Complementary Optimization technology the revolutionary, POWAFREE Cell-Pack 2500 continues to dis/charge even in below-freezing conditions when faced with extremely cold temperatures.

Even in below-freezing weather, POWAFREE Solar Panels turn sunlight into electricity. That's because POWAFREE Solar Panels absorb energy from our sun's abundant light, not the sun's heat. Indeed, cold climates are actually optimal for solar panel efficiency. Hence, as long as sunlight is hitting the solar panels, it will generate electricity.

4. I have had my solar panel system installed and would like to store the extra generated power in a battery system. Can I pair it with POWAFREE Balcony Solar?

Yes, as long as your solar panel system meets the entry requirements to POWAFREE PV Controller. The maximum input should be less than 800W, within the voltage range is 12-60 VoC and a current max of 15A can be used. Take note that input voltage that exceeds the input range can cause permanent damage to the POWAFREE PV Controller.

The POWAFREE PV Controller connects your installed solar panel to POWAFREE Battery Pack, with another end to the microinverter.

5. Who needs POWAFREE Balcony Solar?

Everyone else from balcony tenants (new entrants), retrofitting (already solar-powered houses) to solar-savvy and DIY enthusiasts. Not to mention, all Mother Planet lovers.
