There is no flow from the primary panel. There cannot be. It is an emergency panel feed from the genie. As far as a short, if there was a short in the feed to the battery charging system, the battery woulda died long before 2 years and 2 months in service.
The deal is that that the Honda charging system is point zero fuck all while the unit is running. It will charge the battery if it is being operated 8 hours a day MINIMUM. That is, commercial use. NOBODY buys a Honda like this one for commercial use because they do NOT need or want the features that Honda sells these genies for at such a HIGH price. It's guys like me that want the features but it's guys like me they want to sell their EXPENSIVE batteries to that last until two months after the warranty is over because of the shit charging system.
