Magnum inverter/charger remote display info? Not in manual.

all this fancy complicated electronics installed in a lot of rv's have so many settings that the vast majority of people will never understand and care not to learn about because it is just to complicated.
evan the installers rarely understand the settings for what they are installing. unless the manufacturers hold training programs for the installers or a tech at the rv dealers most will never understand how it works or how it should be setup so the customer is left to figure it out or just use it improperly.
