Ecoflow continue to impress. Their 220w portable solar panels are next level quality, which you come to expect from the company that took the confusion away from inverters and did the unthinkable, building them into the battery. I have tried many battery and panel combinations and am yet to find a more user friendly, portable and practical solution than the Ecoflow Max 2000 and four 220w panels. My only complaint would have been the weight of the Delta Max 2000 battery, however I got sent a complimentary Ecoflow cart with my order, that solved that problem quite adequately. Fold up the cart, put the battery and panels in the boot and I'm off adventuring anyplace.
