The problem is the low wattage not the voltage. If you get a higher wattage panel you will be fine. The panel you are using is way undersized for the job you are asking it to do.
In addition to the input voltage, it also depends on whether there is current. If the sunlight condition is too bad, the solar panel has almost no current input to the EB3A, and EB3A will not get charged.
For me, the same - the update didn’t solve the problem. But soldering a capacitor as was recommended in the forum (sorry, don’t have the link, but easily searchable) does solve it, and charging goes below 20w.
hello chat
Unfortunately my EB3A works poorly or not with solar input.
“Input” flashes on the display and the app reports a low PV voltage.
The open loop PV voltage is between 20-22V and 0.66A - it is a 150W panel in low solar irradiance.
My other small power station then makes at least 4 to 10 watts but the Bluetti only flashes.
At some point around noon it starts charging, the only problem is that while the input warning is showing, the display always stays on and drains the small battery extremely.
Software is available at ARM V 2053.07 and DSP V 2052.07

Hello,
As usual with any customer service, you will get apologizes, explanations, encouragements and maybe, if you are lucky, a new firmware… But, finally, the problem will never be solved and a new “revolutionary” model will replace the actual one, pushing old problems under the carpet for ever.
I had same problems as yours and i solved it this way (kind of bad medication on unknown disease) 
- I did overpaneling : 2 x 170W solar panel to get 180W input
- follow advice of one member of this forum consisting in installation of a capacitor on the input solar cable
Now, i can get a normal behavior of the EB3A. It means, i can start charging at about 6:30AM to 6:30PM with peaks of 185W input.
This powerstation obviously have a solar charging problem, but i guess that they will never fix it…
As others brands, Bluetti prefers to give some powerstations for free to Youtubers who will do marketing rather than helping customers who already paid for their products. It is a pity.

It appears that the eb3a requires a minimum amount of solar wattage to reliable charge and you are expecting a charge under minimal solar conditions. If you are only getting 4 to 10 watts from your 150 watt panel my suggestion would be to re think your solar panel set up and placement because the way it is now is just not going to cut it.

Thank you.
It appears that you resolved not only the solar panel issue but a problem that I was having getting the proper amount of juice via the 12 volt car adapter,( which I had not mentioned,)
I had the van idling in the 1:30 sun and the display read that I was receiving a little over 100 watts.
However I may have another problem. For the last two days the display has been indicating 35% when the unit was 100% depleted.
Also the AC / inverter doesn’t turn on faithfully every time… be it by pushing the button or using the Bluetooth.
Is there a way to reset it?
Thank you for your help

Still getting the blinking input showing 000 Watts, even under sunlight exposition.
I’ve changed already this unit twice but still having the same issue.
Although it says I have 30h left to run battery.
Can you push firmware to solve this?
Please provide me with the SN of the EB3A and the firmware version, and I can check if there’s a suitable firmware for you.
@pW0lf1 I’m sorry that the firmware is the latest one. If the AC charging works, did you try to use another solar charging cable to test if it works?
Unbelievable. I have a powerstation that doesn’t work properly. Paid almost 1000€ by that time to have a powerstation that can only be charged on grid. My solar panel is absolutely useless.
Now I have, 100% sunlight condition and still doesn’t charge my EB3A.
I’ve returned already twice, the unit and you haven’t fixed or replaced by a new one!
How can we solve this in a proper way?
The first image shows when it’s connected with the solar panel cable, the second one, without…
Please provide me with the ARM and DSP versions as well then I can check. Thank you.
I have a PV200 solar panel and it’s exactly the same thing. Even on a full sunny day doesn’t charge at all!
I finally did the tests at home and “apparently” this Solar Panel PV200 is not working properly, once I found no Amper coming out.
I will attach the “proof” with a multimeter showing no results. The Volt seems okay, but the Amper not.
I tried also with the DC port (don’t know if I did right or wrong, but did the same test).
You have no amps coming out because there is no load and you do not have your test leads correctly oriented. You can only measure voltage when the panel is not connected to anything

You’re wrong @Scott-Benson
I managed test correctly and accordingly tho hundred videos of specialists showing on the internet.
The solar panel was only under the sunlight, and the voltage was 21.7v but the amperage has shown only 0.5a. Exactly the same way I did the test with the voltage but different settings on the multimeter.
