Stacking inverters to increase output from 800 watts to 1000 watts using microprocessors is discussed, with emphasis on the need for synchronization among inverters. A participant suggests that simply connecting microprocessors to consumer-type inverters may not work without significant modifications, which could be impractical. The discussion highlights the necessity of additional intelligence in inverters for proper synchronization, specifically mentioning grid tie inverters as a solution. Concerns are raised about the feasibility of reverse engineering existing inverters due to their fixed configurations. Ultimately, purchasing a larger inverter is recommended as a more straightforward solution.
