Thanks everyone. Here are some answers/input:
- Already have IQ4 purchased so will get it installed for next trip
- Good excuse if nothing else to add more solar so I will start looking into that.
- Use the RV once to twice a month for weekends primarily and sits in storage with solar charging active (no shore power charges) and all other 12V turned off with the main 12V switch
- Only ran them dead once maybe twice but very low many times now
- I typically get a little over 3 amps of solar charge and have seen up to 5 amps briefly. Does this correlate to what wattage panel I likely have? Again, I cant find any markings on it and bought RV used so clueless.
- I have seen voltage a bit above 13V previously but never above 12.7 after a long generator charge.
- I was getting spoiled with the solar so have been leaving the inverter on to power portable satellite and TV with a good amount of TV use so it makes sense not getting a good deep charge during the day
- I store/use in high elevation for summer use and desert in winter so temps are usually 40-50's for lows and 60's to 80's for highs
Does the undercharging theory still hold even when it sits weeks in storage with no use with the 3 amps or so providing charging or does it just need a long high amp charge?
One of my main concerns is that I use to get 13.4V with generator running now only 13V. What explains this or is there an adjustment on generator/converter I need to do?
