Isn't it amazing how the sun angle changes the charging cycle? Glad your learning more about Solar.....

If you're going to be down there in the winter as well then you'll want to tilt the panels. In S AZ I tilt mine in Jan & Feb as that makes a big difference in output

Okay. Based on that information I'd wager that you haven't been supplying enough solar energy to charge your batteries. Instead, you've only been making barely enough to offset the fridge usage during the day and depleting the battery the rest of the time. You haven't really been "charging" the battery...at best you've been supplying a surface charge. The voltages you're seeing from the battery now indicate that it's dead or nearly dead. The fridge isn't working because there isn't enough power left to run it. You have to increase the amount of solar power you're bringing in (more time in the sun, more panels, panels with a higher power output), decrease the load on the battery (run the loads for less time, switch to more energy efficient appliances), or both. You may also need to replace the battery if you've depleted it to the point of damage. I have three 100 W panels. If I add one more 100W would that pretty much solve it? The issues did not happen immediately after installing the fridge, they started after installing a fuse box and some additional fuses for the battery per Renogy recommendation. I live in Southern California, so I don't think winter sun will affect me as much as in other parts of the country. Either way, I'm going to leave it in the sun all day today and not draw from it. Hopefully it'll charge up with just the three panels. Have you seen any improvements? At least with the 20A Voyager, you're limited to 3 X 100W panels unfortunately. If you want to expand your solar system, it would probably be in your best interest to purchase a higher Amp one. Depending on long term goals, a 30-40A is a good start. -Renogy Team |

If it were me I wouldn't buy anything smaller than a 40a CC or larger...
