Odd EcoFlow charging pattern: is something wrong?

I live in southern Spain. I have one 200W solar panel and an EcoFlow Delta 2 battery / portable charger. Both are a couple of months old.

The panel faces southeast, which at this time of day is a good direction for it. Today is sunny with a little cloud cover.

I noticed that the charge to the EcoFlow is really strange as of today. It cycles up to about 90 watts and then plummets back to 0 a few seconds later.

Right now there's direct sun on the panel, and the input is at 0. It seems to be hanging out at 0 for the most part.

I put some video in an album, which you can view at the link below.

I have white electrical tape around the cables to prevent them being killed by the UV rays here, which are intense in the summer. Hoping that this is not the issue.

This is the first time I notice this, and it seems wrong.

Hi Liz,
Wondering if your charge controller within the unit is on the fritz?
Cable connections secured well and dry?
I assume this is the first time its happened and that its continuing the trend today?

It's the first time I see the issue.

I'm told that EcoFlow support in Europe (where I am) is quite good, so I'm going to try them.

Sigh, the unit is brand new.

On their FAQ page 3, their is this question.
Seems to be directly related to your problem.

"Why is my power station input power hopping when i try to charge it? How do i fix this?
To fix this, try charging and discharging the unit 3 times. If it still occurs, please provide a video demonstrating the issue and contact support.eu@ecoflow.com"
