PowerBloc®

Whole House

Awesome Power and Deep Storage. The PowerBloc uses a highly innovative dual core that delivers power to the inverter at 600 Volts, allowing us to use inverters that are more efficient and compact than those used by other solar-battery systems. We can also scale energy storage independently of the rest of the system and offer ”deep” storage at some of the lowest costs in the industry.
Unlimited Potential Made Simple. The PowerBloc is modular and highly scalable, which is important because all homes are different and customers have individual needs. But we know a lot about houses and can get you started with pre-configured PowerBloc units. The PowerBloc can be easily customized and expanded to meet your needs.

PowerBloc SIERRA™

Vacation Home or Cabin

Critical Loads Panel, Energy-efficient Home, Cabin. Some customers only want to power critical loads or have an energy-efficient home or cabin. For these customers, the PowerBloc SIERRA™ is perfect. Instead of a 600 V inverter, SIERRA uses a 50 V inverter.

SIERRA uses the same primary core as the regular PowerBloc. It is therefore possible to convert a SIERRA into a regular PowerBloc in the future.

PowerBloc for the Whole House

Awesome Power and Large Storage. The PowerBloc comes as rack-mounted modules in a compact cabinet. The PowerBloc has a dual 400/600 V core. Energy is managed at 400 V while power is delivered to the inverter at 600 V. The result is a super-efficient nanogrid with incredible power and cost-effective energy storage.

Power Up. In the United States, utilities traditionally deliver 24 kW or 48 kW of power, commonly referred to as “100 Amp” or “200 Amp” service. Power needs will increase as our homes electrify with electric cooktops, vehicle charging, and heat pumps. We are already living in that future. We offer the PowerBloc in power units of 25 kW. You can combine eight of them for up to 200 kW of power, equivalent to an “800 Amp” service.

Fill the Storage. We recommend having about 24 hours of storage at average consumption measured during the season of highest demand. This amount of storage balances day-to-day variation in the sunshine, makes energy management easier and allows going into a sudden power outage with confidence.

Pre-configured Units. The PowerBloc is a fully parallel nano-grid, and our designers can Build Your Power Bloc by Bloc to meet even the most complex and demanding requirements. But for most of our customers, our pre-configured units are perfect and allow building large systems quickly.

  • BASE™ 25-70 delivers 25 kW of AC Power to the home, equivalent to a 100 A utility service. It has 70 kWh of energy storage and includes all connections to a solar array, the grid, and a generator. The unit comprises two cabinets.
  • STORE™ 20 and STORE 40 are storage expansion units that add 20 kWh and 40 kWh energy storage, respectively, to the PowerBloc.
  • PEAK™ 25-30 adds 25kW of AC power and 30 kWh energy storage to the PowerBloc.

The BASE unit was designed to replace 100 A (24 kW) utility service and is perfect for many homes. However, many homes need 200 A (48 kW) of service. Adding a PEAK unit gives the home 50 kW of power, equivalent to 200 A service. In many cases, a home’s energy consumption requires an additional STORE 20 or STORE 40.

The table below illustrates which PowerBloc units can replace 100, 200 or 300 A utility service.

This sizing tool is only an approximate indication of the specifications of a PowerBloc needed for a certain home.

Buy with Confidence. Be bold and put your PowerBloc together. Chances are you will get it right. But regardless, we will review all PowerBloc designs and confirm your design goals so you can buy your PowerBloc confidently. Our design team can also help you create the PowerBloc that is right for you.

Mix and Match

The possibilities of a PowerBloc are nearly unlimited. We have designed a PowerBloc to power a home in downtown Calistoga, CA, a clinic in Key West, FL, and an apartment building in the Bronx, NY. With the PowerBloc, you will likely run out of space before you run out of possibilities.

Customizing Your PowerBloc

The pre-configured PowerBloc units, BASE, STORE, and PEAK, are the perfect fit for most customers, but you can customize and expand them. Check out the Bloc by Bloc section of our website to learn about PowerBloc modules and contact our design team to help you customize your solution.

PowerBloc SIERRA™ for Small Homes or Cabins

Perfect for Critical Loads, Small Homes, or Cabins. If you only want to power critical loads or have a small home or cabin, the PowerBloc SIERRA is perfect for you. SIERRA shares the same highly efficient primary core as the regular PowerBloc, but instead of a 600 V inverter, SIERRA uses a 50 V inverter.

The Small PowerBloc with Mighty Potential. The PowerBloc SIERRA is available with inverters of various sizes, which are more powerful than those of most solar+battery systems on the market. SIERRA uses the same primary core as the regular PowerBloc. Therefore, it is possible to convert SIERRA into a regular PowerBloc.

Don’t Get Stuck at Low Voltage. It is only recently that 50 V off-grid systems became popular. These are cost-effective systems with very reliable inverters. However, a 50 V inverter is not as efficient as the 600 V inverters used in the regular PowerBloc. It is also not practical to deliver the 25 kW, let alone 200 kW of power, using a 50 V inverter. However, unlike in other 50 V systems, all energy management in SIERRA occurs at an efficient 400 V core common to all PowerBloc. Therefore, you can convert a PowerBloc SIERRA into a regular PowerBloc! How is that for the best of both worlds?

Ready for the Future

Convert a PowerBloc SIERRA to a regular PowerBloc

Power systems at 50 V are quickly becoming a classic. There is much that recommends them for low-power applications. But among systems with 50 V inverters, only the PowerBloc SIERRA is built on the efficient 400 V core common to all PowerBlocs. This means you can convert the PowerBloc SIERRA to a regular PowerBloc. So, by buying a PowerBloc SIERRA, you get a perfect system today that is ready for your future power needs.
