There are many mobile battery systems on the market, and they are more or less built the same way: a bank of batteries connected to a central inverter. Instagrid does things differently. They break down this central inverter into multiple micro-level inverters, each connected to an individual battery module. Using software and electronics, these modules work together to generate a pure AC sine wave.
This innovation is a significant advance in power conversion technology and enables Instagrid products to be drastically smaller, lighter, and more powerful than other battery systems.
