I have a system control panel for inverter and ags, model 809-0911 that is in need of replacement due to a dim light and getting dimmer all the time. Is that model inter changeable with the model 809-0910? That seems to be the model that one finds online. Most say that model is compatible with SW3000. My inverter is a RS2000 model. Al's and RV Connection here in Yuma want over $300 for it and don't know anything about the different model number. Abes in Maine wants $200. I think that the 0910 is probably a replacement for the 0911 but don't know why the number would go backwards rather than forwards. Any thoughts?
