Our community has rated this post as helpful. If you agree, why not thank reihlthing

I have one and it only seems to pull about half its capacity in ideal conditions

I have the same one and it pulls 185 watts in ideal conditions.

I had two. Best it can do was 120-130 watts each in direct sunlight. Packaging was also pretty cheap. Both boxes were destroyed when it got to me. Panels was fine. I also had one leaning up my van when wind blew it over. The panel side slam against the ground but, surprisingly, no damage. I had it on the roof of my van and drove all over the country. It held up just fine. It's ok if you need cheap panels but performance was lacking for me so I eventually upgraded to something else.

I get a bit confused by open, max, and short numbers in relation amps and volts listed on panels.
The Bluetti EB3A specs states:
  • OCV: 12-28V
  • Input Current: 8.5A MAx
  • Input Power 200W Max
If I understand the info from this panel posted in the OP, it should be ok, correct?

I have the double sided version and have not tested it but they are large. Definitely not "portable" very easily. Kinda wished I got a folding one for my power outage backup plan D that will mainly live in the garage

It's ok - but will suck. It's why people say the panel is not output the correct amount - the panel is fine. Since the panel voltage is 20.2volts and the Bluetti can only take 8.5amps - the max power is 171.7 watts in perfect conditions and usually meaning the perfect angle. You will get about 130watts in real conditions.

You need to look at a higher voltage panel to get max power - not to exceed the 28volt bluetti limit - also you have to factor in voltage rise of the panel in the winter . You never want to exceed voltage - it burns things up - the both devices will self limit amps.

You have to check voltage & amps & watts in both devices - to find ones that play together nice for max power

Panels are really sensitive to angle - at 10am a 200watt panel flat mounted will only do about 90watts - tilt it to a correct angle it will do 175watts.

I often see 400w 40v panels for sale for $30-50 in FB Marketplace. Bring a voltmeter I suppose, but used panels from older installs can be had for a good price.

There is a Voltage - Current curve which depends on the sunlight intensity. When it is open circuit, the panel has a maximum voltage output, however when you start to draw energy by increasing the output current, the voltage goes down (At short circuit condition, there is almost no voltage output). Since the power output is the multiplication of voltage and current, there is an "optimal" point which can give you maximum power output. Usually you need a controller to dynamically find this point.
