Thanks for the Max. Voc spec. The next time it's cloudy enough to see no charging at the Bluetii, I strongly suspect that pulling the plug and carefully measuring the voltage at the 8mm plug will show something less than 16V. Whenever the voltage reaches 16V, the Bluetti will show at least...

If the EB240's controller will not accept more than 10A, what's the point of ever putting even two panels rated at greater than 100W (5A) in parallel? Is it just an expensive hedge against cloudy weather? Hobotech exhibits no concern for generating more than 10A using a 3S2P array of six 12V...

I've built a fan-cooled, 5A, 12V-to-48V converter that works great for charging the EB240 from a vehicle's 12V power jack, while driving: https://diysolarforum.com/threads/bluetti-eb150-and-power-inverter-500w-4-2-amps.10655/post-147428

Occasionally, yes, but only in ideal conditions of bright sun, clear skies, cold air, perfect angle, clean panels and no shadows. If the voltage is excessive, the Bluetti will protect itself, but you won't know to reset it until you next look at the LCD display and see an Error 17. It might go...

Hi @dmholmes , Having twice watched that video you linked, the creator seems very credible to me and if the charge controller of the solar generator reports a faster charge rate, what's not to like? The convertor he links beneath the video is "currently unavailable" at Amazon, but they have...

I cannot recall details of Hobotech's testing of the EB150's inverter, but you might refer to that video to see if he had determined an instantaneous maximum output, hopefully greater than your 1150W need. I like the idea of multiple units (2x EB150) vs. a single, larger unit, not only for...

I would encourage you to remain optimistic until you've measured the voltages and polarities at all three conductors of the 8mm plug in question, when it is energized - as I described above - referencing the measurements taken at the 8mm plug of the energized charger that's made for your...

Hi, You might be able to deploy a folding plastic table for elevating the panels above the height of the railing, oriented verically, with perhaps a strip of 2x2 pine, C-clamped atop the table, lengthwise, against which to rest the bottom edge of the panels, propped up against the wall. No...

The Bluetti EB240, for example, has a 12V DC power socket that can only deliver 9 Amps, continuously, so you would only be able to operate the trolling motor at the lowest speed setting (8 Amps). Even then, when the motor first starts, it might attempt to pull more than 9A, momentarily, which...

I'm late to this thread, but if you were to buy two more of the exact same panels that you have, adding them in parallel, you would still be at less than 60V, but your total wattage under ideal conditions would be 800W - which would only go to waste under ideal conditions. Your array would come...

I should think it will work in practice, too, and having some panels in parallel will help the whole array perform better on overcast days, plus any shade that falls on one cell of one series of three panels will not be a detriment to the other series of three. Happy cabling!

Thanks! You took a very fortuitous shortcut (pun intended), having retained the proprietary soldering at the 7.9mm plug of that Blueitti cable. ? Nice going!

Dang! You're all set! ????????

Sweet! Thanks for this update. Going by some Hobotech videos I've watched on YT, there's about a 10% difference between Amps going into the EB150 and Watts displayed as input, due to controller losses. The Bluetti is displaying the actual Watts being delivered to the battery, after controller...

Uggh! That was, at first consideration, a lame response from Bluetti support, but perhaps there's just a loss in translation from Mandarin to English. My interpretation, giving them the benefit of the doubt, is that they suspect the extension cables you've tried thus far were of insufficient...

Hi @ETWiss , Looking at your profile, I was hoping to see addtional posts regarding your EB240, but I just took delivery yesterday and wanted to comiserate and/or cocelebrate, while continuing with the topic you started. I've got three 180W BougeRV panels, purchased in ignorance, basically...

See Forbisher's comment #2. With a 2s2P array, your input voltage to the EB240 charge controller will not come anywhere near the 68V maxiumum, but you will still get the same Wattage coming out of the four panels as you would if they were in series. You could also aim one series pair about 5...

By the way, there is a difference between the 8mm barrel connectors on cables produced by Bluetti and those found on nearly every other 8mm cable or adapter found for other solar generators (at least for the EB240). Bluetti uses a three-conductor 7.9mm barrel connector and solders the (+) cable...

Question: What is the minimum input voltage required by the MPPT charger of the Bluetti AC50s? Answer: 14V (up to 40V) Problem: Even with the engine running, the alternator will not keep the voltage at or above 14V while under load. Use the 12V car charger, instead. ? Or...

The flanges on those voltmeters only overhang by 2mm, so cutting the holes to be just large enough and no larger, was tedious. I started by drawing 25mm x 45mm rectangles with a fine-point marker. Then I drilled holes in all four corners of each hole, before going in with the cut-off disk...

Ouch! The Bluetti AC charger can pull "7.5A Max" at 120VAC = 900 Watts. So even that 700W inverter I linked above, would be insufficient. 900 Watts is akin to a small coffee brewer or microwave oven. You would need a 1000W inverter, to avoid running it full out = more money, heavier cables...

Bummer.

Hi wtj! The last sentence of your post contains a critical piece of the puzzle that I had missed when first reading it: You're saying that current output drops on cloudy days! I didn't know that! Actually, after posting my question several hours ago, I realized that I had no clue whether...

Here's another way to charge the EB150 or EB240 without sunshine or AC power - a fan-cooled, 5A, 12V-to-48V converter (that's more efficient and less cumbersome than using a 300W inverter+AC charger in a vehicle)...

Thanks @MBR ! Your first sentence, alone, is of great value given that I've searched and searched, finding no answer. ? I'm afraid I'm stuck with my 8.91A, 23.84 Voc panels, for now, though. In your experience, how common is it to attach a voltmeter's leads to a panel and actually get a...

I haven't found any cables that shunt the center pin to the inner shell of the 8mm plug, as required by Bluetti. Quoting a link from my post #10, above, you could build your omn cables using this solderable plug...

Hi Seldomseen2u, Ironically, I've been seldom seen at this thread, so I apologize for neglecting your questions and it's a shame those Newark connectors aren't true 3-pole solderable. Their drawings led me to believe otherwise. You certainly seem to be working things out pretty well on your...

Hi, I think you're onto the cause of your problem. Test the extension cable with a different cigarette lighter socket (in another vehicle). If it works OK there, you might need a new socket in the Vanagon. Otherwise, replace that extension cable with a different design, but keep in mind...

That's great news, Harwood. Congrats! Yes, Bluetti Support could have stated their requirements in a more practical way. (Hint: How many customers can measure the Amps delivered at the charge port?) But we managed to read between the lines to solve the problem. :) I have a couple of...

The 12V DC socket of the EB240 can supply 9 Amps, continuously, so you could augment the built-in 1000W inverter by connecting an external inverter, rated no higher than 100W. (100W / 12V = 8.33A)
