xantrex freedom marine 1500 inverter/charger issues
I am currently living on a 34ft Morgan that is equipped with a great little xantrex freedom marine 1500 inverter/charger. The two battery banks that are currently lead acid type.. are at the end of their lifespan and I have purchased two AGM batteries to replace them. I see in the user manual for the inverter that I should be able to hold down the 'invert' button for five seconds.. and then press the charge button... in order to see/select which battery type the unit is set to charge. I need to change it to AGM, but when I hold down the buttons.. nothing on the display changes.
I am wondering if I can not select the battery type until I disconnect the current batteries? I just wanted to make sure my unit's buttons are responsive before I go disconnecting everything.
Does anyone else have any experience with installing these units/ know of any problems with the two buttons on the front?
