≈ 0.2 days (24h/day) · Safe motor start buffer (88.6% margin).
oxygen concentrator running (420 W max) and start-up (650 W max) draw fit the Pecron E1500LFP's 2,200 W continuous / 4,400 W surge ratings.
low flow setting 1–2 LPM continuous delivery (280 W)
standard prescription flow rate 3 LPM continuous operation (350 W)
maximum continuous flow setting 5 LPM at maximum pressure (420 W)
≈ 0.2 days (24h/day)
System standby power: 16W (4% of total draw)
Provides 4× CEE 7/3 (230V) (120V 60Hz).
Pure sine wave inverter output. Safe for sensitive medical electronics and variable-speed motors.
Inductive motor/compressor load with 1.4× starting surge (motor inrush) (88.6% worst-case surge margin).
Wall AC fast charge at up to 1400W (70m to 80%, 95m to 100%).
Safe envelope verified: Starting surge (500W) remains comfortably below the 4400W surge trip line, with steady-state operation settling into the safe continuous zone at 350W.
About 3.8 hours on AC power, with the oxygen concentrator averaging 350 W (standard prescription flow rate 3 LPM continuous operation (350 W)). The Pecron E1500LFP then draws about 399 W from its battery, including 16 W for the inverter itself. Best case: about 4.8 hours (low flow setting 1–2 LPM continuous delivery (280 W)). Worst case: about 3.2 hours (maximum continuous flow setting 5 LPM at maximum pressure (420 W)).
Yes. The oxygen concentrator's start-up peak of about 500 W (up to 650 W) fits within the Pecron E1500LFP's 4,400 W surge rating, with 85% headroom even in the worst case.
On wall power: about 70 minutes to 80% and 95 minutes to full (Pecron figures). With its maximum 700 W of solar input connected, expect about 560 W in full sun, so a full recharge takes roughly 2.9 hours of full sun, so it can refill in a single day with 4 peak sun hours.
It can act as a backup supply: with the oxygen concentrator plugged into the Pecron E1500LFP and the Pecron E1500LFP plugged into the wall, it switches the oxygen concentrator to battery in about 20 ms when the grid fails (Pecron calls this EPS mode).
