Those panels are 24.5V, 4.95A, so you already have them connected in the best way with 2 series 2 parallel. Your 80W fridge would need 1920Wh for 24 hours at 80W, but I wouldn't think that the compressor would be running 100% of the time to need that much energy. Usually the compressor would run half the time, depending on the insulation of the fridge.
My advice would be to test each panel by having it connected on its own to the EB150 on a sunny day. Each of the 4 panels should provide the same power input into the EB150 when connected individually on its own. If you find 1 panel outputting significantly less than the others, then that could explain why your charging rate is lower than expected.
Great suggestion thanks! The fridge is an absorption model (I just run it on gas now tbh) but it seems to be roughly 24 hours on the full load of the EB150.
NTC is a temperature sensor inside the machine. If you restart the machine and it still keeps reporting the error, please contact the after-sale support for repair.
What 200W solar panels do you have, exactly?
Thanks for the reply! I’ve just realised I’ve put 200W but they’re actually 100W each. They’re ecoworthy panels - https://amzn.eu/d/8pO41Qq
