Hi folks, hoping this is the right place for this, looking for advice for keeping my battery in good shape and having an optimal setup. The short version: my converter works fine but is an old Progressive Dynamics unit and I'm 90% sure it doesn't charge the battery. I am adding solar but would like a reliable shore power charging option. Should I upgrade the converter to something more modern with a built-in smart charger or carry a separate battery charger? If so, for a single battery, do I need something with a significantly higher amp output than my battery tender (which is about 1.5v)? Any recommendations on models of converters or battery chargers I should look at? Can I have the solar and a battery charger connected to the battery at the same time? Details: Me: Noob. The PUP: 1991 Viking Deluxe 180. The converter: Progressive Dynamics with the serial number PD6809--can't ID it specifically on their website but appears similar to the documentation they have for the PD688 series. I am unsure if it charges or not but I am pretty sure not. Works great, no issues. The battery: a single 12v AGM 75aH. I own two, I alternate them for each trip, I maintain them when not in use off the camper with a battery tender plus. The setup: standard ceiling and outside lights (LED bulbs); added inside and outside LED strips, two cigarette sockets, and 4 2.1 USB ports. 400W power inverter option connected directly to the battery (but only when we absolutely need it, otherwise it's stored). Adding a 100W solar panel and charge controller which will also be connected directly to the battery. We've only taken it out for short trips so far but are planning a longer trip for next year that may involve 2-3 days between access to shore power. Recently weekend camped with no shore power and had no problems for two days although the cheap voltage meter I installed was showing pretty low by the next night (10.5-11v). We did not experience any loss of power. I want to make sure I'm treating my batteries right while having a set up that makes the best sense. What do you think?
