I have the same problem. See https://diysolarforum.com/threads/ecoflow-delta-problems-solar-problems.44043/ No response from Shop Solar Kits.com yet...

Received an EcoFlow Delta and Rich Solar 200w briefcase panels from ShopSolarKits.com. I don't think the Solar Charge Controller is working correctly but need your advice. AC charging works fine. 12v cigarette charging works fine. But when I plug in the panels, the input (watts reading) on the...

Thanks Mattb4 - evidently even when the current is lower, at 5.4 A, the watts reading is still all over the place. I've asked Shop Solar Kits to exchange the unit for another. From what I can tell, this is what the reading should look like for a power station that's working (see 7:10): Fairly...

Droomboter - Thanks for the additional information. I was thinking the same thing - firmware update. Too bad we can't just do that ourselves. BTW I'm using the Rich Solar 200W briefcase panels, essentially 2X100W panels sandwiched together. Don't know what "half cells" are but definitely not...

My problem did require a firmware update. I sent the EcoFlow Delta to them and they lost it. So they sent me another unit. It must of had the newer firmware because the problem went away. In your case, I don't think you should see such a wide fluctuation. I have a 200w "briefcase" panel and it...

Yes, 78% is the battery charge level. I only have a multimeter and am measuring the output from the panels directly. The specs on the Ecoflow Delta say that it can handle panels up to 400W, 10-65V and 10A max [Link]. Isn't 11.94A too much (see attached images)? If the SCC receives too many...

Glad to hear you were successful. Did you have to send in the power supply, or did you do the firmware update yourself?

Thank you again. I left my number with them today. Hopefully they will call tomorrow. I will not mention our conversation. Wish me luck!

Michaellyne - thanks for the confirmation. I can see in another thread that we are not the only ones with the problem. See: https://diysolarforum.com/threads/delta-ecoflow-mppt-problem.43051/ Ecoflow actually says you can have up to 400W of solar connected - the only way I could see that...
