yup, and they are well aware that a signed utility approval paper does not act like a wireless back-feed isolation device as some seem to think.

Retired Duke Energy EE.

The simple fact of doing without permission has absolutely no impact on lineman.

In Indiana Duke goes by the Inverter rating, not the combined panel rating.

Be interested to hear more about this, and not just from the hardware side. If you were to include VRM, firmware quality and updates in response to issues, support, hardware and complete eco-system stackup how do Sol-Ark vs Victron compare?

How soon till battery manufactures raise their pricing 30%?

OppenOffice has been fairly stagnant for many years, LibreOffice is the one in active development and the one that resides in most/all Linux repos, plus available for download for Mac/Windows.

Their own videos show they have no clue what they are doing, plus they are hostile to customers, can't think of any reason to support their business. But I get your joke!

That site has essentially zero information, and it's $50k for 40kWhs. At least one other company tried this before and went belly up, don't recall for what reason though.

Interesting. I've been generating more than I use for about 5 years now, so far no issues, but I'm in Indiana.

My lab (Indiana) is available, can load and/or charge test, both AH and Wh.

I really need to go back through all of my issues with these guys. Not terrible but definitely have significant room for improvement, 75% might be about right.

Thanks for the video and the honesty, really glad I never did business with those guys.

26 SEER 120v here: https://hvacdirect.com/9-000-btu-23-seer-wall-mount-gree-mini-split-vireo-single-zone-heat-pump-vir09hp115v1b.html

My 33 SEER Mr Slim uses 3-4kWh per day in the 90s F here in the midwest. This is cooling about 1500sq' but is very well insulated.

For my testing I am logging both AH and Wh.

I'd argue absolutely! Eliminating a runner especially in a 1S configuration will allow you to get the most of the pack. Docan advertises grade A, but I am already seeing a 10AH delta on cells, though I'm only 3 tests in so far. I will post the entire lot once complete. I'm not sure I...

I just started testing 35 from Docan, but it will take me over a month to complete!

In general most deep cycle batts are OK with the above absorption and float settings, however IMO the EQ is set a bit high (more appropriate generic value would be 60v), but for now that's not an immediate issue. I also don't like the max absorption time, depends on how much solar and battery...

I also replied to your other thread, might be more we can help on there as well.

Give the two screenshots above (assuming they were taken at the same time) the battery voltage is at the absorption charge set point voltage, so it's not going to charge further. And assuming i'm reading it correctly with the window in the way the EQ charge voltage is set incorrect at 54.8V.

Victron makes great stuff and their forums are the place for help, along with here. If it's truly fried (note it has a 5 year warranty) and suits your needs i'd replace it like and kind.

Same issue attempting to buy from Amy, 3 diff credit cards and Paypal all declined, Credit Card companies say they don't even see a transaction so they are not declining.

Has anyone written any python to utilize the back-end library for say reading cell voltages? A simple example would help me get started! Thank you @MrSurly for making this and making it public.

The ones currently listed for $110 are the non K version, and it's unclear if shipping is included in that price.

Interesting! Does the controller allow for an adjustable RPM setting like a typical governor vs a *throttle* like driving a car?

Yeah that surprised me too! Doesn't seem to be all that much info floating around, think I'll start a new thread on this subject as I'm definitely going to build something.

Slightly off topic but does anyhow have any mower blade motor specs? Like RPM, kW etc? I'd like to build a finish mower pull-behind and either buy some factory motors/controllers or have a basic understanding of how powerful they need to be.

Much agreed, it goes great until all of the sudden it doesn't, just like the Michael debacle.

Got a reply from Docan, they accept paypal, visa and master card, no American Express.

I sent them an email earlier today asking about payment options, will report back when they respond.

Not for me, go to checkout and the only option is Bank transfer.

I just mentioned this in one of the other threads, think I'm going to do the same thing.

I just noticed that Docan no longer offers a PayPal option, only bank transfer. My first purchase was great and was planning on 34 more but not sure about bank transfer only. (tried lower quantities so it's not just because it's over $5k total)

I just received 12 (280k) myself, all perfect as well. Took a week to ship, but i'm not complaining one bit.
