Related question, Jeff... With the Sol-Ark, I an off-grid situation can you set it up to always use inveters to power loads. In other words, when the generator kicks in, only use the generator to charge batteries and do not bypass inveters to power loads directly from the generator.
This is a request I get occasionally. People don't want to rely on the "dirty" generator power with sensitive electronics.
