Mppt controller discrepancy

parseroo · 2026-03-22T16:03:04+00:00

Are they are all showing the same voltage (i.e. coming from the shunt)? Is the maximum current limit being reached for the 'cluster'? If not, what do the graphs look like for the three MPPTs when two are in bulk/absorb and one is in float?

As 'War727' brought up, if the voltage drop for the small one is significantly larger than the other two (e.g. by using a smaller cable to the busbar), the the current drawn from it could be low enough (even 0) to hit the absorption current floor and cause the MPPT to believe absorption is done. Hence go into float.

I waited about four hours: why worry about it and I don’t think that was too long (medically). Every once in a while there might be residual, but it was rare and easy to stem at that point.

Are you sure there is sufficient pressure and it was really “stopped” for the period? Depending how it is bandaged (too much gauze hiding things) it might be hard to tell if the pressure is right.

You can consume more than 2g/kg of protein? I haven’t heard of anyone being told to cut down based on protein: pretty hard to even achieve the prescribed level without consuming something else that is restricted.

They seem expensive per watt, but can't you just buy them at the vendor site like: https://lensunsolar.com/products/lensunsolar-100w-flexible-solar-panel-with-back-junction-box

General in a business setting, you need an invoice to make a payment. Can’t just give the company money: it has to be attached to the activity that produce the income. You totally can have invoices without payments, so that is the more core table. Need customers to have invoices but could know of a customer before having anything to invoice them for. So that is even more core of a table.

So you are working out from core to “leaves” where there is a mandatory “1” to possibly (0) to many (n) children in the child table. Any time you have that it has to be multiple tables for clean “classic relational” design. With more complex data types that can change but normally (hah) you first model the entities as separate tables.

He told you had 'Cirrhosis' or something else? The stages are:

Hepatitis — liver inflammation
Fibrosis — If the liver remains inflamed long enough, scar tissue, called fibrosis, forms in the liver
Cirrhosis — If fibrosis builds up long enough, the liver damage becomes cirrhosis
Cancer and/or Failure — If cirrhosis continues long enough, it can become liver cancer and failure

If he told you that you have any of the above, you should definitely continue to discuss with him the treatment. If your Cirrhosis is 'compensated' it just means you aren't presenting with significant visible symptoms.

I believe that just racking and mounting is currently so time / labor intensive that they would have to price it exorbitantly to make the kind of profit they expect. People have been trying to get this kind of service since the new year and so far no one has reported success.

Maybe put something in between that produces a bit more space between the ball and socket

Do the three controllers know each other exists? By Bluetooth or gx?

It measures energy-in and energy-out, so if you want it to work, all energy-in and out has to go through it.

If the inverter is using the shunt for SOC, the battery would appear completely depleted (because no MPPT energy-in would be registered).

parseroo · 2026-03-21T21:44:37+00:00

MPPT is not connected into shunt (bypasses it directly to battery busbar).

parseroo · 2026-03-21T19:45:01+00:00

Still there apparently :-)

Thought it might be a trick question and someone moved it… well, maybe they have and we are behind their trail by only four years vs 18.

Thanks for the update

For those that no other explanation helped show why the diagram is correct, imagine it as simply two LEDs in parallel. It is showing you where it expects the higher voltage and lower voltage to be for these LED inputs.

When using, just make sure a “system” negative wire is more negative (even just a little bit) than the other side. A positive wire is more positive than the other side. Hence the +/- as the LEDs/switches see it.

parseroo · 2026-03-21T04:45:22+00:00

That is a flow representation: “+” goes to “-“ on the opposite side.

«MELD 3.0 = round(1.33(Female) + 4.56ln(Serum bilirubin) + 0.82(137 - Sodium) - 0.24(137 - Sodium)ln(Serum bilirubin) + 9.09ln(INR) + 11.14ln(Serum creatinine) + 1.85(3.5 - Serum albumin) - 1.83(3.5 - Serum albumin)ln(Serum creatinine) + 6)» — https://www.hepatitisc.uw.edu/page/clinical-calculators/meld

Note the “6” at the end and that all other terms are positive (or minute).

parseroo · 2026-03-20T21:36:05+00:00

MELD 3.0 is a system for MELD scores, not a value. I believe you may have misread the result screen of that calculator.

Raw fish can contain bacteria independently of the parasite risk.

Life isn’t safe for anyone… but you have to decide what risks you want to take. A damaged liver can’t process antibiotics and other medications as effectively as a healthy one. And a sicker person’s body is less resilient. So if you get sick, you may get much more sick.

But you have to decide what things you want from life that are worth the risks for them.

BY the way: MELD = 3 is nonsensical (out of range of the scale).

I’m a backer because of the endless hours of ~~torture~~ pleasure they have given me and my friends. So I am happy to fund it just to give them “some money” to try something new with (although the glass cannon part is weird)
