About GridBlock

GridBlock is an innovative energy router that dynamically manages the flow of energy between multiple sources and loads and is able to create and operate a self-contained microgrid. GridBlock packetizes and routes electrical energy with isolation and high accuracy to serve AC or DC systems seamlessly. The precision technology enables a bidirectional power flow on multiple ports or channels concurrently, bringing the flexibility and control of Internet routers and switches to the electrical grid. Increasingly, electrical installations require smart integration of EV or e-truck charging, battery storage, solar panels, and critical loads, with custom design and build for each location adding to the cost of implementation. GridBlock simplifies all of this with a flexible, software-defined, modular solution that can manage a wide variety of end-use configurations and applications. GridBlock is part of Endeavour, a purpose-built company taking on global challenges to guarantee renewable energy and clean water to everyone, everywhere by decentralizing infrastructure, developing new technologies, and deploying energy, water, and waste valorization solutions that are more profitable than those that currently exist. Endeavour companies are made up of passionate change-makers who want to leave the world better than the way we found it.
