EcoFlow Delta Pro Solar Charging

[SolarRookie-612]

I was wondering anyone was gotten anywhere close to the 1600w max solar input on a EcoFlow Delta Pro. I am talking about actual input being received by the Delta Pro. Is it possible with the Solar input specs of 11-150V, 15A Max, 1600W Max? If so, which panels are in the array and what is the wiring configuration?

Yes. Using 8 Trina 245w panels, with 2 4-panel strings connected in parallel. Actual input voltage measured at Ecoflow port input is 133v, under ideal conditions gets close to 1.6kw.

Thank you for your response. Interesting that that config. comes in at 133v. Does it ever exceed the 150v limit?

Looking at the data sheet, the STC/NOCT Voc is 37.5/34.2. In theory it could hit 150v but I have never seen it go over 133. I always measure before plugging in. Note that I have not tried running in winter yet.

I bought 385w panels and plan to do two series of three panels (2300 watts and 22 amps in a perfect world which doesn't exist). Volts will be about 120v. On youtube, it was shown that going over 150v will shut off the MPPT, but going over 1600 watts won't. The excess wattage is ignored.

Crazy from research! Have 2 EF DPs , each with 2 EBs arriving shortly and trying to safely connect to solar power. Located in deep South Texas so snow is not a problem, until the poles reverse! Finely found EF's recommendations for 4- 400wt panels (their panels are 37.1VOC, 13.79ISC). Looking to outside market found ZNSHINE ZXM7-SH108 Series as a close match-37.1;13.7. My math says 4 in series yields 148.4 V and 13.7A--2033W max and after 20%loss = 1626W. Considering purchasing 8 panels - 4 for each unit and extra batteries. BUT retired firefighter husband doesn't want any over paneling. Being Texans we found Mission Solar MSE Perc 430 (49.28VOC; 11.24A). Only 3 in series produces 1662W and after loss 1329W and probably take around 9hrs to recharge each set - no worry with time issue. Hubby more happy with this one and likes the temp coefficient of VOC considering our high temps.
Can anyone bring me some sanity!!!! Thanks in advance and so glad to find this forum...

Late response but three panels in series at 49V is too much for an MPPT controller rated to 150V. Any temperature drop below 25C will cause the magic smoke to release.

It seems like the voltage rating on the DP is hogwash. Everyone says not to do it. or get close to 150 v.
