Did a quick test with the VL45ProS and Bluetti AC180. The fridge was set at 36* (already at temp) empty in my garage at around 80-85* the Bluetti had enough juice to last for 31 hours. Good baseline to go off.
full fridge at 36/38* it ranges from 15-17hrs depending variables likes temp outside and how many times its open and closed. The solar panels full charge the EB3A in about 2.5-3hrs at 75-90KW if its cranking at 110-120kw then around 2hrs
