Common questions
What people ask about the Delta Pro 3600W Portable Power Station
What's the difference between Delta Pro 3600W Portable Power Station and a residential all-in-one inverter-battery?
EcoFlow Delta Pro 3600W Portable Power Station is a solar generator (portable power station) — designed to be picked up and moved, with built-in outlets and a solar input port. It's distinct from a residential AIO like the EcoFlow PowerOcean or Sol-Ark 12K, which is a permanent-install hybrid inverter wired into a home's main panel. Solar generators excel at backup-of-last-resort, off-grid trips, and powering specific high-priority devices. Residential AIOs are what you'd choose to back up the whole home.
What can EcoFlow Delta Pro 3600W Portable Power Station actually run, and for how long?
With 3600W continuous AC output, EcoFlow Delta Pro 3600W Portable Power Station can run anything that draws under that wattage continuously: refrigerators (~150W), LED lights, laptops, modems, CPAP machines, even small space heaters at low setting. Surge to 7200W means it can handle motor-startup spikes from compressors and small pumps. At 3.6kWh capacity, runtime depends on draw: a 60W draw runs 51 hours, a 600W draw runs 5.1 hours. (The 0.85 factor is realistic round-trip efficiency.)
How do I expand capacity?
EcoFlow Delta Pro 3600W Portable Power Station expands to 25kWh total via add-on battery packs from the same manufacturer. The expansion battery connects with a single high-current cable and the BMS treats the combined bank as one battery. Note that the inverter section's continuous AC output (3600W) doesn't increase with capacity — only runtime does.
Will this charge from the panels I already have?
EcoFlow Delta Pro 3600W Portable Power Station accepts solar input via a built-in MPPT charger. The exact voltage range and max wattage on this unit aren't in our verified spec set — confirm before pairing with rooftop or portable panels, as solar generator MPPTs typically have tight voltage windows that not every panel string fits.
