PowerBloc™

PowerBloc™ is the ultimate solar+battery nano-grid for the home. PowerBloc is a primary power supply that completely insulates the home from any utility outages. PowerBloc’s high-discharge batteries and high-power inverter can supply all loads in a house, including air conditioners or well pumps, regardless of whether the grid is up or down. PowerBloc can even charge an electric vehicle.

Because PowerBloc’s inverter runs the house at all times, the user won’t even notice when the utility power fails. Power conditioning equipment is no longer needed to protect sensitive devices such as flat-screen TVs or desktop computers. The PowerBloc can even seamlessly integrated a generator to assure that the lights stay on even during extended outages or to allow the home to be entirely off the grid.

“YouSolar installed a PowerBloc at our off-grid house in Big Sur. This fully automated nano-grid uses solar energy and a propane generator as energy sources. After years of struggling with other off-grid systems, the PowerBloc has now provided continuous power for months. YouSolar’s technical expertise and customer service are simply excellent.”

Many Sizes Fit All.

The PowerBloc™ is a modular and expandable system. You can choose the size and number of power modules (“blocs”) to fit your needs. Our experts can help you to choose the system that is right for you. You can start small and expand your system as your goals or your needs grow without any design changes to your system. We always leave some room in the cabinet for growth (or you can get a second cabinet if needed.) Want more storage? Just add another battery module. Want to integrate a generator? Add the generator integration module. You can add expansions in any open slot. The arrangement of modules does not matter. Everything is plug- and-play and there are no delicate connectors that can fail.

Just Add Power.

The PowerBloc™ can use any solar panel technology. Each panel comes equipped with a STEP™ DC-DC micro-converter which is mounted to the racking. To maximize the use of each STEP, panels with 350-450 Watt of capacity are optimal. When smaller panels are used, especially in retro-fits, one STEP may be used for two panels. STEP creates a plug-and-play solar array which gives you flexibility in the placement and number of panels.

STEP™ also boosts energy production of the array by 15%. Nice. You can expand your array at any time even with other types of panels for up to 50+ kW of solar power. You can also easily integrate a generator. Simple. Just add it with the EXTEND™ rectifier. You have a small wind turbine or micro hydro? No problem at all. PowerBloc can integrate it all.

Multi-Source Off-Grid Power

There isn’t anything the PowerBloc™ cannot do. YouSolar installed a PowerBloc™ solar+battery nano-grid at an off-grid house located in Big Sur, California. The primary energy source is solar, but a small propane-powered generator seamlessly integrates for complete reliability. The
system is fully automated. The house sources nearly all of its electric energy from solar.

YouSolar’s energy management system decides on when to start the generator. The system makes that decision based on real-time solar radiation forecasts from YouSolar’s solar forecast service. The PowerBloc™ is monitored over a satellite link but runs autonomously whenever the
link is down.

Goodbye generator. Welcome savings and serenity.

Energy costs from a YouSolar™ PowerBloc™ are a fraction of that from a propane or diesel generator which are traditionally used for backup of off-grid power. At today’s prices, propane or diesel power for home or business costs U.S.$ 1.25 or 0.55 per kilowatt-hour, respectively, while power from the PowerBloc can be as little as U.S.$ 0.20 cents per kilowatt-hour.

Then there is the serenity your PowerBloc™ solar+battery system brings. It puts an end to noxious emissions, noise, vibrations, and you will never run out of fuel.

AROUND THE CLOCK CUSTOMER SERVICE

World Class Support

No matter where you are, our customer service is there for you 24 hours a day, 7 days a week, because life takes no break. If your system is internet-connected and you have allowed remote monitoring, we probably already know the solution before you know that you have a problem! But in all cases the DIYA™ user interface allows you to trouble shoot the system and our parallel power architecture allows in most cases for the system to run even if a component experiences a failure.
