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 Ecoflow Delta is all over the place. Ramps up to 65w, then 120w, 150w, then back to zero, and starts all over again. This sequence repeats over and over again. Never does the input stay anywhere near consistent. The fans on the battery come on almost instantly. I'm worried that the SCC on the Ecoflow is going to give out from the stress of starting over all the time.
Here's a video of the input showing how it resets to zero after a very short period of time (taken on a full sunny day in the southwestern desert):

Here's a video showing the Amps reading from my multi-meter - not sure this is important but wanted to include in case it was.

The response from ShopSolarKits is as follows:
"This is Nelson your Technical Product Specialist from Shop Solar Kits.
We have reviewed your video and it seems that the fluctuations happen due to the over current of the panels.
It exceeded the max current rating by 0.8A. EcoFlow 1800 should have clipped the Ampere at around 10A but this has caused your unit to fluctuate. What we are concerned about should be the sum of the wattage you actually gather per day and if it averages a steady daily generation.
However, if the fluctuations bother you, then we can offer you some alternatives. "
I'm less concerned about the "sum of the wattage gathered during the day" then I am about destroying the SCC on the EcoFlow.
What is the problem? Too many Amps from the panels, or a defective SCC?
Any help is appreciated! - Stephen
