Capacity
AC200MAX: +788 Wh (+62.5%).
This comparison targets buyers weighing raw capacity and longevity against portability and faster solar turnaround. The AC200MAX delivers 2048 Wh of LFP battery storage with 3500 cycle life, nearly triple the 800 cycles offered by the DELTA's NMC cells.
It also pushes 2200W of running power and handles 45 out of 53 tested devices, giving it a clear edge for home backup and high-draw appliances. Surge capacity reaches 4800W versus the DELTA's 3300W, adding headroom for motor-driven loads like refrigerators and power tools.
Expandable battery support on the AC200MAX further extends its versatility for extended outages. The tradeoff is physical: the DELTA weighs just 30.9 lbs, roughly half the AC200MAX's 61.9 lbs, and its 4.5-hour solar charge time beats the AC200MAX's 7.3 hours despite a lower 400W solar input ceiling.
