Ride through any power outage.

The PowerBloc™ is a primary power supply to a home or business. Its super-lightweight, high-efficiency inverter delivers ample power to start and run high-demand appliances such as air conditioners. Solar panels with panel-integrated micro converters create an efficient, modular, and shade-tolerant solar array. High discharge-rate battery packs with bi-directional converters store energy and make sure that enough power is available for peak loads.

The PowerBloc™ is connected to the grid through a durable rectifier built on a cutting-edge topology. Its batteries immediately make up power when the utility is down. You will never notice any interruption, not even a glitch, when the utility’s power fails and later returns.

The PowerBloc™’s power architecture insulates a customer from the grid rides through any power outages without a glitch. The PowerBloc™ delivers perfect and constant power in any situation.

PowerBloc™ can be sized to cover many hours of power outages or to deliver as much energy as desired. The use of a fuel generator can “extend the range” of the batteries where reliability is an absolute must. Going from partial self-supply to being entirely off the grid only requires adding more batteries and solar panels with no need to otherwise change the system.

Power supply is seamless and controlled by an intelligent energy management system which delivers a solar production forecast, learns load patterns and allows users to select performance targets. The system can be monitored and controlled on an intuitive user interface table that is part of the system.


Meet the Ultimate Power Architecture

All PowerBloc™ solar+battery systems are based on the emerging  380V DC bus standard using proprietary and state-of-the-art power electronics for seamless reliable and powerful operation. The system is modular and expandable up to the maximum system capacity, 40kW for the HOME™ and FIELD™ models and 64kW for the COMM™ model. The electric potential of the bus is set by the inverter input and all components of the PowerBloc™ adjust their output potential to account for any line losses up to the inverter input. This feature, called “self-leveling” allows one or multiple solar arrays or a fuel generator to be as much as 100 meters way from the inverter. All components are “hot-swappable” making installation and use of the system simple and safe.

The components

The SHIELD™ Rectifier completely isolates the home or business from any grid-problems that could damage sensitive electronics thus eliminating the need for surge suppressors or power stabilizers. Grid power spikes or dips have virtually no effect on the SHIELD™’s steady DC output. Its rapid response time makes it ideal for solar+battery systems where both load and solar output can be highly variable. The SHIELD™ rectifier is a compact continuous AC-DC rectifier that uses proprietary bridgeless rectifier technology coupled with SiC MOSFET components for highest performance and maximum power. Circuit damage due to fluctuations of the grid are eliminated which significantly increases its operating life compared to conventional diode-bridge technology. The highly efficient SHIELD™ only needs small heat sinks which saves on size, weight and costs. The SHIELD™ comes in blades and up to multiple blades can be used in parallel to increase power.

SHIELD™  Blade Sizes:

HOME™: 5 kW (up to 8 blades)

COMM™: 16 kW (up to 4 blades)

FIELD™: 5 kW (up to 8 blades)

The FORCE™ Inverter is a high-power grid-forming inverter with a 2 x surge capacity that allows it to start motors, such as in air conditioners, water pumps or refrigerators. The FORCE™ is the first all-silicon carbide grid-forming inverter and superlight weight. For example, the 5kW FORCE™ for the HOME™ has a mass of only 2.5kg including its heat sink! The FORCE™ comes in blades and multiple blades can be used in parallel to increase power.

HOME™: 5kW sustained)/10 kW peak (up to 3 blades)

COMM™: 16 kW sustained)/32 kW peak (up to 2 blades)

FIELD™: 5kW sustained/10 kW peak (up to 3 blades)

The SINK™ Inverter is a supplemental grid-tied inverter that allows PowerBloc™ to send excess solar (or other renewable) energy to the grid. SINK™ is only recommended where net-metering is available and considerable amounts of solar/renewable energy cannot be “self-used” by the customer. The use of SINK™ will require utility approval.

The STEP™ Micro-Converter is a panel-level DC-DC micro-converter that steps up each solar panel’s potential from 30-50 Volt to the potential of the 380 V DC bus. STEP™ uses an innovative two-stage switching network to achieve 97% conversion efficiency. Panel-level Maximum Power Point Tracking (MPPT) results in up to 15% more energy production per array compared to a string array using the same panels. STEP™ communicates with the PowerBloc™’s TRAFFIC™ controller over power line communication. STEP™ automatically shuts down if communication to the TRAFFIC™ controller is lost due to fault in the power line from the solar array or through a user command on the DIYA™ User Interface. The STEP™ is integrated into the panel replacing the traditional junction box or is available as a rack-mounted external device that allows the use of customer-specified panels.

The TWIN™ Converter is a high-power bi-directional DC-DC converter that is part of each battery module and steps up (and down) the battery pack’s electric potential. The TWIN™ can charge and discharge at any rate of 0-1kW for each kWh of battery capacity—for example, a 4kWh module could charge and discharge at 4 kW. Response to power demand from the inverter in discharge mode is instantaneous and a short 50 millisecond delay when switching from charge to discharge. (The FORCE™ inverter’s capacitance assures that there is never a “dip” in output even when the TWIN™ must reverse direction to deliver power.) The TWIN™ allows batteries of different chemistry and specifications to operate on the system.

The EXTEND™ Rectifier allows the integration of supplemental AC power sources, such as small fuel generators, wind turbines or hydro generators. The EXTEND™ can accept power at frequencies of ten to hundreds of Hertz and electric potentials of up to 500 Volts. The use of wind, bio-mass or hydro power that is uncorrelated to solar production greatly increases energy reliability and a fuel generator can act as a “range extender” that tops of the battery when needed. When used as a range extender, a generator can run at optimal engine frequency, thus significantly increasing its efficiency. In contrast, a generator that is directly connected to and follows the load must be greatly oversized to meet peak load and thus mostly runs part-load with poor fuel efficiency.

The TRAFFIC™ Controller monitors and controls energy and power on the system. TRAFFIC™ is the core of the PowerBloc™. TRAFFIC™ runs the EDISON™ Energy Management System that operates the system to meet user selectable operating criteria. It collects analyzes, compresses and stores data and communicates with the DIYA™ User Interface and YouSolar™ back office over WIFI or wireless SIM card. TRAFFIC™ also receives and disseminates activation codes to protect all system components from theft.

The EDISON™ Energy Management System is a learning and smart optimization engine which forecasts solar production, load and power outages (where frequent) and then allows the user to operate the PowerBloc™ solar+battery system to meet certain targets, such as highest reliability, maximum solar energy use, or lowest energy cost. EDISON™ makes intelligent decisions for the use which makes operating the PowerBloc™ solar+battery systems effortless.

YouSolar’s historical and real-time solar irradiance data service, SPOT™, has global coverage and includes terrain shading. SPOT™ accesses historical and real-time meteorological data from international satellites to create a location-specific historical data set and real-time forecast. We use historical data to configure the PowerBloc™ nano-grid during the design process. When the PowerBloc is operating, every hour, SPOT™ sends an hourly forecast for the next days to each PowerBloc™. This data is then used by the Energy Management System to create a solar production forecast.

The DIYA™ User Interface is a beautiful and highly intuitive user interface that makes understanding and controlling the PowerBloc™ easy and enjoyable. DIYA™ only provides the information users want to know. But DIYA™ is much more than a dashboard; it allows control of the PowerBloc™ including choosing performance targets for the EDISON™ Energy Management System, trouble shooting or rapid shutdown of the entire system. DIYA™’s home screen is a practical time piece and weather station while providing system performance cleverly integrated into the dial of the clock.

The PowerBloc™ uses safe and high-discharge LiFePObatteries which are non-volatile and require no active cooling. Each battery pack is equipped with a battery management system and a TWIN™ Bi-Directional Converter creating battery module of which multiple modules can be connected in parallel. The TWIN™ converter allows the use of any battery chemistry that may become available in the future and even allows mixing different type of batteries within the same PowerBloc™.

  • HOME™: 4 kWh (up to 10 modules)
  • COMM™: 8 or 12 kWh (up to 10 modules)
  • FIELD™: 4 kWh (up to 10 modules)

The PowerBloc™ can use any type of solar panel with a maximum power of 380 Watt|DC. Each panel is equipped with a STEP™ Micro-Converter. YouSolar™ uses both glass and flexible, glass-free mono-crystalline solar panels with panel-integrated STEP™ Micro-Converters. The advantages of the flexible, glass-free FEATHER™ panels are their superlight weight (7.5kg) and flexibility. These features make distribution and installation of these panels easy and allow their use on uneven surfaces and roofs that cannot support the weight of glass panels. For customers who want to provide their own panels, a rack-mounted STEP™ Micro-Converter is also available.

The STACK™ Modular Cabinet is a plug-and-play system where power components are contained in a module that is stackable. The only electrical connections between modules are the positive and negative bus poles. All communication across the modules is wireless. The STACK™ modular cabinet is used in the HOME™ and FIELD™ modules.


How it works.


Today’s legacy grid

In today’s legacy power grid, it’s necessary for power plants and distribution systems to be oversized just to meet peak load. Most of the time, the legacy grid barely uses half its capacity, while consumers still bear the full cost through their utility rates.

Tomorrow’s hybrid

In tomorrow’s hybrid power grid power plants and distribution systems have higher utilization rates. Average demand is lower because of distributed solar systems, but peak demand is even lower because much of it is delivered by distributed batteries. The result is an electric supply that is cheaper, greener and more reliable than the legacy grid.
