During my search for some type of AC unit that could run completely on solar I found many but most were overseas and nothing being sold here in the states until I came across Hotspot Energy and their hybrid mini split. This of course was before Signature Solar started selling the EG4 solar mini splits. But Hotspot Energy wanted over 2k for a 12k btu unit and I said aww hell no. Then Signature Solar started selling them and at 1299.00 I got 4 lol but Hotspot Energy did have this cool device which I can only assume is similar to the inverter system that is in the EG4 solar mini splits. It basically takes solar and lets you power any 120 or 240 A/C appliance with solar and grid as backup. But again they wanted like 1800.00 for just the 120 volt one, way too much, has anyone seen something similar for sale? I've been looking and searching online with no luck. I wish EG4 (Deye) would make this product lol
