The language used is "4-year battery warranty". Leoch refers to the complete unit as a solar generator, so unless the batteries have failed...

Make sure that number is trustworthy. Bluetti vastly overstates the surge capacity on some of their units. I know zero about Ecoflow so maybe their numbers mean something.

Here's a recent review from Amazon that states the user modified his EZ Switches for use with his Bluetti. Seems to contradict everything I've read. 5.0 out of 5 stars Easy to use with my Bluetti Ac200P Reviewed in the United States on August 21, 2023 Verified Purchase I recently purchased a...

Similar situation. The USA was warned of possible rolling blackouts prior to the summer of '22. My research into the packaged units presented me with a bunch of unfamiliar names and competing claims of usefulness and quality. In the end, I chose the Bluetti EB200 offered by MillerTech (I...

The primary means of charging is the 400W power block that came with the Bluetti, so no real means to regulate/monitor voltage or current (what units are you using when you say limit charging current to 0.2C)? It seems the best I can do here is charge to between 80-90% and hope the power isn't...

What's the best practice for power outages re a Bluetti EB200 (similar to AC200)? Conventional wisdom says not to store the units above a ~50% SOC but that's a very limiting parameter if the lights go out without warning. I have a couple of panels but I don't want to depend on solar to top off...

SOGEN PV input generally has a minimum voltage and/or wattage requirement. If your panel falls below the specified cutoff, it will not charge. This may or may not be your issue; check the specs to know for sure.

I bought two panels recently which were not packed well and had shipping damage. I decided to keep them since the damage is primarily cosmetic—and the seller gave me a partial refund. One thing that concerns me is a couple scratches one panel's backsheet. These look pretty superficial but I...

Interesting. There's been quite a bit of back and forth re Bluetti units which apparently MUST have a switched neutral transfer or damage will result. EcoFlow has no such limitation apparently?

The image on Amazon shows MC4 cables are ~6 inches long and no junction box? Am I seeing that correctly?

As I understand it, Voc (voltage, open circuit) is the spec to go by when sizing your PV panels. If you will be using PV charging in cooler weather you should know the voltage of the panels may increase above Voc in sunny conditions, so stay maybe 20% below your max voltage input. Or do the math...

Today, the PV input finally cracked 300W consistently, saw a peak of 326W while I was observing. Sky was still not 100% free of clouds, at best there was still a high haze. I'm glad the Bluetti 35V minimum PV input spec seems not to be a hard cutoff; the input is almost always less than 35V.

Simultaneous charge/discharge The EB200 can do this but the manual says: Supported but not recommended in order to protect the lifespan of the battery. How detrimental is this? Are there certain scenarios that are ok and others that are not?

I appreciate that you responded but I'm not a big fan of answers that amount to, "Go read a book."

Given that these units have a floating neutral with AC outlets that are not grounded, what happens if the device you're powering has a fault, short, whatever?

Another test today, better sky with ~50% cloud cover reported (looked more clear than that to me). Temp was 85°. I saw 300W once, most of the time the power ranged from 250W-285W.

Silicone paste did the trick. I see now I could have shoved it together without lube, but I'm from the don't force it school. For future reference, I have the HF 180pc metric Viton o-ring kit (67525). The one that worked for me was A010, 6.07x1.78. Almost as good as 5.32 ?

Yeah, I have their Viton set. No go. Well, let's put it this way, I found one that's an OK fit, but it doesn't want to connect to its mate. Maybe some silicone paste...

I thought this would be an easy spec to find, but I am striking out. Anyone know? Whatever it is, it's not one I have on hand.

First panel test today on the "good" side of the house; power maxed out at 110W. Kind of disappointing for two 200W panels, though we did have ~95% cloud cover at that time according to the Weather Channel. Not sure what my expectations should be in those conditions. Looks like no real chance...

I'm adding panels to my EB200, using rigid panels in a temporary config--meaning that I will only put them out when I need to charge via solar and store them away the rest of the time. The warnings say not to connect/disconnect MC4s under power. Does this apply to all the other, non-MC4...

I just received the panels yesterday. My observations so far: Unboxing: BougeRV packaging is substandard, IMHO. I've never received solar panels before so I don't know how other vendors pack their goods, but these were single boxed with a thick cardboard protector over the glass, plus corner...

I meant from trees, but point taken. The input specs on the Bluetti simply say Solar charging: 35V-150V/12A. Vmp for the panel is 17.98±3% while Voc is 21.62±3%. Not sure if I answered your question or not. My concern is not falling below the 35V required by Bluetti.

My Bluetti requires 35 V minimum for PV input. I have ordered two 200 W panels with a Voc of 21.62±3%, giving me adequate voltage in a series config. My question is, how much will the voltage be likely to drop when cloud cover is heavy? Shade will not be an issue.

Good info, one is opening near me soon Thanks!

Where did you order your Qcells from?

I had no idea that HF has solar panels. But why not, they have everything else... ? Thanks for the info.

So I've been pretty much running myself nuts trying to choose solar panels for my EB200. Finally settled on these for better or worse. I'll report back when they arrive and are in service.

Thanks for the reply. I was beginning to think this was the wrong place to find answers to questions. I did charge to 100% before I used it, so maybe I accidentally did something right. With regard to sitting and waiting, I bought the Bluetti for blackout protection and I don't have much day...

After having the Bluetti EB200 for about 2 weeks and trying to learn about this technology, I've got questions not answered by the user manual. Searching online often yields inconclusive or even contradictory results. For example: A new unit should be discharged FIRST before fully charging A...

Ok, well I already blew that since I charged mine first. Do you have a link to that info from Bluetti?

The documentation that came with the EB200 is lacking, more of a quick start guide than anything else, so some unanswered questions. #1: Elsewhere I've seen advice to charge these units to 100% then run it down to Ø a couple of times to "calibrate". Is this a good or bad idea? Or does it matter?

Ok, guess we take their word for it... but it would be nice if someone who's done a teardown would verify. I wasn't aware of the weight factor, thanks.
