Capacity
DELTA Pro 3: +1,024 Wh (+33.3%).
This comparison targets buyers shopping for a high-capacity LFP power station suited to home backup, off-grid solar setups, or heavy appliance coverage. The DELTA Pro 3 leads with 4000W running power, 8000W surge, and a larger 4096 Wh battery, giving it a slight edge in device compatibility at 48 out of 53 loads tested versus 47 for the Pecron E3600LFP.
It also delivers 4000 rated cycles, about 14% more longevity than the E3600LFP's 3500. The Pecron fights back with a meaningful weight advantage of 79.4 lbs compared to 113.5 lbs, a 20ms UPS function the DELTA Pro 3 lacks, and a dramatically faster solar charge time of roughly 5.5 hours versus 14.6 hours at comparable max input.
If portability and rapid solar replenishment matter more than peak wattage, the tradeoff tilts toward Pecron.
