i have 4 fullriver DC150 AGM batteries http://www.fullriver.com/products/ad...e/DC150-12.pdf in our van with a xantrex freedome 3000 inverter/charger and a set of 4 lensun panels and a tracer controller. in full sun the panels don't seem to produce enough power to charge the batteries. my voltage will hover at 12.7-12.9. before i added the solar i would drain 30% of my batteries on a hot day (powering the fridge, etc) but now i pretty much hold my own or gain a little during the sunlight hours. what i am finding though that is odd is that after a couple days i might be down to 12.4 volts on my batteries but if i plug in the xantrex charger (which i have on a relay to cut out the solar panels) it takes many hours to recharge. i plugged in this morning and 7 hours later i am still bulk charging at 25A (charger can put out 150A) and voltage is up to 13.3. in the past i have seen the batteries recovered from this level of depletion much faster.
i am concerned that i am doing some kind of damage to my batteries with the underpowered solar charging. can anyone help me understand what might be happening?
