I have my AC200Max connected to two 200W solar panels. When I plug them directly into the DC Input port I’m only getting 5 to 12 volts, 0 watts. When I use the DC Enhancer I get 53 volts and 100 watts. It’s slightly overcast here but not that bad, and obviously the panels work. Is there something I should try to get the wattage up? Ideally I’d like to charge through the DC and the AC (using the enhancer) simultaneously but I don’t want to buy more panels if there’s something wrong with the DC input
