I do have a 180 as well as several other models that have the same situation with regards to solar input amperage limits creating a lower than optimal real world solar yield. I think I did a review on the 56 a few years back that brought this point up as a negative as well. With car charge mode being recognized as 12 to 26 volts or so (to include 24 volt vehicles) that does not leave much room between that voltage and the solar recognized voltage. Many people were (and still do) burn up their car socket or car charge plug due to a steady high amp draw. 8 amps is now common amongst the major players as max car charge amperage and a single panel does not put out high enough voltage to not be recognized as car charge instead of a solar panel attached. Does Bluetti do a great job communicating this detail? Of course they do not and could improve. The interesting thing to me is a lack of recognition that all models of power stations have combinations of panel types and quantities that youāre less than optimal results. Any combination of panels which output exceeds the amperage input limits will result in less than optimal solar charging wattage. In the specific case of the 180 I would simply recommend removing the 24 V car charge as a recognize car charge voltage and only recognized 12 V systems. This would expand the lower limit of solar charging and therefore would recognize a single 200 W panel at the max amp rate of 10.
Thatās answers my question too. BLUETTI_CARE I was only getting 8a il check that when it goes over 30v it goes to 10a
This solar panel illustrates the issue pretty well. The AC180 may never let you get more than 8amps into it with that panel. But if they had a programmable voltage threshold you could. Their answer has been just run out and buy a different solar panel. There you go, problem solved.
This post has the merit of explaining the subject of current limiting as a function of input voltage. I know itās not the answer youāre looking for, but itās not very expensive and it could still be useful one day and maybe solve your problem:

One of the reasons for the DC current limitation is vehicle related. I drive a 2022 Toyota Landcruiser Prado, it has a power socket near the driver seat and another for the second row passengers. The rated power output is 12V @ 10amps, or 120W. However, that is the total limit for both outlets, not each. As an example, if you are drawing the full 8A charging a Bluetti from the front socket and at the same time powering a portable fridge from the rear socket at say 4A, the vehicle fuse will likely blow.
I would imagine that Bluetti have placed the current limitation for that very reason. :)
Kid. Buddy. My Man. Iām not sure why youāre posting as a āmoderatorā in this tread, because you are as helpful as a stubbed toe, and a childish and immature one at thatā¦ What you keep repeating is neither insightful, nor productive. WE ALL GET WHAT YOU ARE SAYING Squirt, and what you are repeating is irrelevant to the conversation. KaMann is correct, and you are incorrect. Bluetti is not forthcoming in their documentation about an 8 amp limit on voltages below 30, which applies to a VAST array of PV products, including my own which is sitting at 29.5V , which is why Iām in here trying to figure out how to get this product at the 10 amp limit that is advertised. If I canāt get a fix for this asap Iāll be returning the product as not delivering as promised. Iām really not sure how you have the free time necessary to spam-post in what can only be described as trolling, but Iād encourage you to go outsideā¦
We shouldnāt HAVE to buy another solar panel, ESPECIALLY if you sell the AC180 in bundle with your 200 watt panel. When a product doesnāt perform up to what is represented, it diminishes trust. Donāt get me wrong, I love my AC180, but please see what you can do firmware wise to address this issue. Otherwise my Bluetti 200 watt panel is basically a big awkward paper weight to me, and I would have rather put that extra money from that solar panel toward another Bluetti product.
Bluetti is just ignoring this completely. They just say itās so you donāt blow the fuse on your carās lighter socket. But how many car lighter sockets out there output more than 14VDC? Answer: NONE. So why is the 8A limit all the way up to 30V? Apparently itās for a 24V car lighter socket that does not exist.
Giving up on Bluetti product now. I complained and they sent me a cheap volt meter to shut me up. It didnāt fix the issue.
This can not be the answer from a company that sells the AC180 in combination with 200-watt panels. please give us an option in the firmware to select the changing source. Protecting carās battery is OK, but you canāt cut the capabilities of our hardware without advertising.
I own 2 bluetti power stations. EB150 and AC180. I liked their products but this will definitely be my last. This 8amp charging limit is absurd. Not to mention the phone app is beyond limited. Go compare it to an Ecoflow where you can adjust the charging parameters etc. It is night and day for control.
Itās too bad, for the most part good products, but the 8 amp charging limit really kills this product and the lack of care is all I need to know
