EcoFlow DELTA Pro 3 with the Renogy 200W N-Type Portable
Works, with caveats · 4S1P · 797 W
Thick mark: cold Voc · Thin mark: operating Vmp, 75.2 V
2 caveats
- The maker publishes no temperature coefficient, so cold voltage uses our conservative −0.40 %/°C.
- The connector type comes from a secondary source, so check the physical port.

Can I connect the Renogy 200W N-Type Portable to the EcoFlow DELTA Pro 3?
Yes, with limits. The best setup is 4 panels wired 4S1P on High-PV Input, delivering up to 797 W. That string reaches 98.5 V at −10 °C against the port’s 150 V limit, using our cautious cold-weather assumption because Renogy publishes no temperature coefficient. Check your own unit’s labels too.
Danger: overvoltage risk. Do not connect the layouts marked red below. Going over a station’s input voltage limit can permanently damage it.
What is the best way to wire Renogy 200W N-Type Portable panels to the EcoFlow DELTA Pro 3?
Wire them 4S1P on High-PV Input for about 797 W from 4 panels. The string runs at 75.2 V, above the 30 V minimum the port needs to start. Stop at 2 in series on the lowest-voltage port, because 3 in series exceeds its limit in the cold.

How cold can it get before this string overvolts the EcoFlow DELTA Pro 3?
A string of 3 Renogy 200W N-Type Portable panels breaches the 60 V limit of Low-PV Input even at 25 °C, before any cold correction. Voltage rises as cells cool, at our assumed −0.40 %/°C (no figure is published), so a clear winter sunrise is the worst case. Stay at 2 in series or fewer there.
The cold-weather correction is the same one NEC Article 690.7 requires for PV system voltage.
Which cable connects the Renogy 200W N-Type Portable to the EcoFlow DELTA Pro 3?
You need an MC4 to XT60 adapter cable, rated for at least 11.3 A, to connect this array’s output to High-PV Input. Confirm the plug against your own station’s port, and check polarity before first use. Keep runs short, because voltage drop grows with current and distance.
How long does the Renogy 200W N-Type Portable take to recharge the EcoFlow DELTA Pro 3?
Expect about 7.3 peak-sun hours for a full charge from 4 panels. That’s 1.2 days in Denver, CO in June and 1.6 days in December, using a 0.70 real-world derate and NREL irradiance data. Clouds, shade and panel angle can all push it longer.

Where do these EcoFlow DELTA Pro 3 and Renogy 200W N-Type Portable numbers come from?
Station limits come from us.ecoflow.com and panel ratings from renogy.com, each checked against a verbatim quote on that page. Panels must also pass a physics test: Vmp times Imp must land within 15% of rated watts. Anything failing goes to quarantine and gets no page.
