EcoFlow DELTA 2 Max Review: Goldilocks Zone Power Station with Solar Limitations“I think the Delta 2 max is one of those goalie loock Zone products it's not too big it's not too small it's just right you can handle both small and large jobs no problem”Open at 20:14

EcoFlow DELTA 2 Max Review: Goldilocks Zone Power Station with Solar Limitations“I also think they could have done better on the solar input a pair of 500 watt inputs in 2023 isn't really that impressive I also didn't like how I had to Max the voltage out over 60 volts in order to reach that 500 watts”Open at 22:06

EcoFlow DELTA 2 Max Review: Goldilocks Zone Power Station with Solar Limitations“in the real world you're likely never to attain 1,000 Watts unless you hit that magic 60 volts that's really tough to do with solar panels”Open at 22:41

EcoFlow DELTA 2 Max Review: Goldilocks Zone Power Station with Solar Limitations“however it is difficult to recommend the ac200 max over the Delta 2 simply because the blue ID design is really starting to show its age and actually doesn't even offer a UPS feature which this does”Open at 24:43

Runtime predictions for your loads
Based on 2,048 Wh capacity · 95% LiFePO4 DoD · 90% AC inverter efficiency. Solar column assumes ~25% of rated input as sustained sun average. Phase-1 uses constant-load math; time-resolved multi-day SOC simulation is the Phase-2 north star.
| Load profile | Continuous draw | Runtime estimate |
|---|---|---|
| CPAP only (overnight) | 60W | 1.2 days |
| Fridge only (cycle-averaged) | 70W | 1.0 days |
| Wifi router + LED lights | 55W | 1.3 days |
| Your full continuous load (215W) | 215W | 8.1 hr |
| Microwave + base load (peak) | 1300W | 1.3 hr |
| Window AC 8,000 BTU (avg) | 700W | 2.5 hr |
Detailed specs
Sourced from manufacturer datasheet · verified 1mo agoFor advanced shoppers. Plug types matter if you have a 30A RV; MPPT range matters if you plan custom solar arrays.
Battery behavior
| Cell chemistry | LiFePO4 |
| Cycle life @ 80% capacity | 3,000 |
| Dimensions | 19.6×9.5×12 |
| Parasitic loss (idle, AC off) | pending verification |
Why parasitic loss matters: for store-and-forget hurricane prep, even ~2W idle drain adds up — a fully charged unit can drain in months sitting in a closet.
Inputs
Solar — PV1XT60
11–60V · 15A max · 500W max
Solar — PV2XT60
11–60V · 15A max · 500W max
Combined solar input: 1000W max total across both PV inputs. Run a higher-voltage series array on the high-V input and a parallel array on the low-V input to use full capacity.
