EG4 12000 BTU Hybrid Solar Window Unit: Frequently Asked Questions Does this really run on solar power directly? Yes. It has a built-in MPPT controller and accepts 75-350VDC directly from solar panels — no separate charge controller needed. It automatically prioritizes solar over AC power whenever solar is available. How many solar panels do I need? EG4 recommends around a 1,400W array, with a hard maximum input of 1,700W and 380V open-circuit voltage. Going well beyond that recommended range isn't something EG4 documents support for — call us at (303) 876-7654 if you're planning a larger array. What happens if there's no sun? It automatically switches to AC-only operation, or runs on Solar with Supplemental AC to make up any shortfall — you're never left without cooling. What size window does it fit? Double-hung windows from 24.9" to 39" wide, with a minimum height of 15.2". Is it energy efficient? It carries a CEER rating of 14.2 and is ENERGY STAR certified and AHRI listed. What refrigerant does it use? R32, which has a lower global warming potential than older refrigerants commonly used in window units. What's covered under warranty? A 5-year limited warranty, which requires product registration. Do you offer financing or price matching? Yes.
