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?
