    I noticed your comment in the [email protected] lithium post. If you have a 320 12V only fridge, it draws between 5A and 7A with a 50% duty cycle: 4 min ON, 4 min OFF, @24hrs. to keep a less than 40° F safe temperature.  That's upwards of 86Ah which would completely drain the stock lead acid deep cycle battery without any charging. With our 160W Zamp solar and full sun for >5 hrs, we cannot keep up with this demand and be able to use lights, radio or fan. Our recourse has been to shut off the fridge from 7PM to 8AM and use a couple of ice chests for less-critical items. I have been investigating all the aspects of lithium ferrite phosphate for 2 years now and am currently designing our replacement system.

      that is an interesting experience. i keep my fridge a 37-38 degree. usually the solar panel keeps up the battery charge during the day for me. by the time the sun drops. the battery is pretty charged up for the night. I even watch TV for few hours. by the morning the battery is at about 70-60% i leave the solar panel connected and is charged again for me. i have the CSS- i dont know if the fridge are different. but seem pretty efficient
