Backup Power is Great. But Consumers Want Perfect, Uninterrupted Power.

After the recent winter storms in California, a potential customer, named Andy, reached out to us. He already has a 6kW solar array and a backup solution consisting of two Tesla Powerwalls. Andy’s total cost for the combined system, which he purchased in 2021, was $64K, including installation and before-tax credits.

Andy was happy to have backup for critical loads during a night-long outage that affected over 5,000 households in his neighborhood in the suburbs of San Francisco.

While the rest of the homes in the street were dark Andy’s lights remained on. He was also able to help out a neighbor who asked him to store sensitive medicine in Andy’s fridge for the duration of the outage.

When It Rains, It Pours | But There Is Still Solar Power

The PowerBloc provides uninterrupted, perfect power that is unmatched in the industry.

However, the transition to the backup battery, and then back to grid power, was far from perfect and woke up the family in the middle of the night.

The few seconds of transition between the grid and backup caused the WiFi router to reboot, the clock on the microwave to reset to 12:00, and the dishwasher and washing machine to quit their programs. Then when the grid power came back at 4 am, the electronic dimmers recalibrated and lit up the entire house like stadium floodlights for several seconds, waking up most of the family.

Having backup power during an outage is great, and these nuisances may seem relatively minor as long as power outages are infrequent.

But the more homes electrify and digitize, the more important reliable power of high quality becomes. And then there are large regions of the world where the power goes out several times a day and poor power quality destroys electronic appliances.

Things will not get better as rapid electrification and growth in demand will put increasing strain on grids everywhere.

With the PowerBloc, YouSolar offers a solution that provides perfect power without ever a flicker, at a price that is competitive with mere backup solutions. Our customers love it. The world needs it.

We are currently serving progressive and well-to-do customers who are willing to pay the “innovation premium” for having perfect power.

But as we increase sales, our prices come down. We will also introduce the stackable version of the PowerBloc® that reduces installation costs. The result is a virtuous cycle allowing us to reach ever broader market segments.
