Fair point. Initially, I am hoping that my Lycan (1000 Watt Hour Standard Battery, can be expanded to another), 100 watt panel, and charging off the alternator when driving around would suffice for a small, efficient fridge. On my next rig, I am planning on 300 watts of solar to handle additional usage. Sunny California and can park the rig in direct sunlight all day.
I figured that I would initially cool down everything off 120 volt and them move to a rig with Renogy + Solar and Drive Charging.
If I precooled, I would be hoping that I would only be getting 1 amp/hr average draw from the fridge say 300 watt/hour a day reasonably continuously. With 100 (or 200) watts of solar and drive charging, I'd think I'd have it covered.
I have read discussions on here about folks successfully running small dometic/arb fridges off Yeti 400s with just 100 watts solar and drive charging only full-time. I was hoping to manage something similar. Thinking I should be aiming for smaller, efficient units like National Luna 40L Classic (60mm insulation) or a small Engel though.
Well, the next installment in the saga commences. I purchased a National Luna 52L Weekender and their standard Anderson cable in addition. However, upon receipt, I noticed their Anderson cable is actually a 15 amp coupler on the fridge end and a 45 amp coupler for some weird reason on the other end. I needed 15 amp coupled to connect to the rear panel Anderson on the renogy lycan. Nevertheless, I had an 10 foot (maybe too long) 15 to 15 Anderson cable laying around. Connected to the fridge and Lycan. It still won’t power up on 12 volts! Have a couple more things to test tomorrow but needless to say I am getting pretty pissed that it does not seem that the Lycan can handle this bone basic common application.
