First Look PowerBloc® Cabinet
arnold2024-08-26T02:43:01+00:00We are excited to give you a first look at the PowerBloc® Gen 3 cabinet currently in production at our manufacturer.
“Two on One”
arnold2024-08-23T07:11:08+00:00Many of our customers’ homes have flat roofs. For aesthetic reasons, the solar array is also expected to be flat, except with a small angle for rainwater to run off. The problem with flat roofs at our Northern California latitudes is that solar production is very “peaky” in the summer: Solar production is 3 times higher in the middle of summer than in the depth of winter. At the same time, loads are typically higher in the winter in Northern California.
The Secret Sauce Has Many Ingredients
arnold2024-08-22T02:32:34+00:00The PowerBloc is the first practical utility replacement. It delivers 100 A of AC at 240 V, which is 24kW. In addition, it is ready to deliver Direct Current (DC) for EVs and the modern all-electric home. The PowerBloc uses a parallel HVDC architecture that is highly efficient and scales easily. It supplies DC or Any AC, even on the same system.
Modularity to the Max
arnold2024-08-19T13:04:27+00:00The PowerBloc® has a parallel architecture, which enables its modularity. Modularity then allows us to customize and easily scale the PowerBloc. The basic PowerBloc, the BASE™, has two cabinets, but many of our customers have six or even eight cabinets. Building a multi-cabinet system means moving many batteries and modules. Thankfully, all that is needed is a dolly. But what about the 7-foot cabinet? How do you move that?
The Blue Ocean and The Red Ocean
arnold2024-08-14T09:56:03+00:00The home solar battery market is highly competitive. We believe the Powerwall 3 is the best home battery system out there, and its competitors have become its bait ball. The smaller the fish, the quicker it is devoured.
There Is Great, and There is “PURRRfect”
arnold2024-08-05T07:08:05+00:00A few weeks ago, we proudly showed you the Gen 3 PowerBloc. The design was great. However, we did not like that the displays, breakers, and state of charge (“SOC”) indicators were not aligned. What if we could align them?
The Making of PowerBloc
arnold2024-08-05T07:04:21+00:00We are a small company, and the PowerBloc is a BIG SYSTEM. So, how do you build something BIG when you are small? Super-lean manufacturing. We design almost every part of the PowerBloc, but we manufacture only a few parts in-house. All other parts are made by our suppliers in Northern California, Minnesota, Shenzhen, China, and elsewhere.
The Revenge of Solar | By Arnold Leitner
arnold2024-07-25T04:18:58+00:00What if I tell you that in the spring of 2001, the United States was about to pull the plug on all large-scale solar research? The reason for the decision was that solar would never be able to provide any meaningful amount of electricity to the power grid.
Wildfires Make Homes Uninsurable
arnold2024-07-23T06:43:05+00:00With increasing wildfires in California, home insurers have begun canceling policies. Here is a post by a homeowner on the neighborhood app NextDoor. The homeowner writes, "there have been home insurance cancellations due to fire risk.” Many other homeowners have experienced the same.
Houston Isn’t the Problem
arnold2024-07-18T03:32:43+00:00We recently spoke with a venture capitalist. He could not understand that our customers spend a hundred thousand dollars or more on a PowerBloc. We have two answers.
