I have a new 2021 Montana High country 334BH, factory installed Solarflex. I know nothing about this and the dealer just jumped over it, the documentation provided was virtually nothing but a flyer. I can't even tell if it is on. It has the Jaboni 30 controller and next to it a display reading 12.9. When I hit the power button on the jaboni controller, it stays on for about 3 seconds then goes dark. From reading other posts, I get the impression I should junk the jaboni and put in a victron (this has bluetooth). Can anyone out there give me some basics on this system?
