RE:RE:RE:RE:An Exro Math problem....There will undoubtedly be some technology that will allow the meshing of 400V and 800 V systems as the engineering evolves eg. HEAT has a product

and EXRO could easily be working on similar tech.
In the meantime, each of EXRO's 100V, 400V, and 800V CD's have their own application and potential customer base and potential income stream

4Front has some more info here on EXRO for those interested:
