For those familiar with my post-whoring ways, this subject line is likely quite shocking. Just trying to make a point... Seemed a good lead into the question. The answer? Because Victron is worth it. It's a small company run by people who give a shit and care about their product, its...

"You'll never see max power out of an array." I've said that dozens of times. Sometimes, my pants are on fire! AZ. Panels tilted at 29.5° at Azimuth 165° (peak solar is at about 11:30am). Only ~6 weeks out from the Winter solstice, which is the worst day of the year for solar. Here's what I...

It has been years in the making, but I finally have the NMC battery poised for deployment... (okay, only half, but still). Summary: 7X Ford Fusion/C-Max Energi PHEV batteries, 7.6kWh rated per pack. Each battery: 84S 25Ah 3.7V NMC cells. Four subpacks of 21S in series Packs have tested...

And there it is... This was your mistake. You should have said, "yes, I attempted to make that purchase." It didn't go through because your bank flagged it when the charge attempt was made.

Many would regard watching their array output update every two seconds akin to watching paint dry... However... When you see your 2970W array output 3975W for a moment, it gives you the tinglies... I think I just smurfed myself...

@SignatureSolarJames Hi. As a disinterested third party observer, in my opinion, your behavior in this thread is reflecting poorly on your organization. If it's a hot Sunday there in TX (is a cool 109°F in AZ right now), and you've had a few brews to cool off, I suggest you make sure you're...

5. Your bank called you to confirm. 6. You said you didn't make the purchase even though you did. 7. Bank concluded a fraudulent purchase attempt was made. 8. Bank cancelled your card.

Why does it matter? There probably is a little bit of a margin. Midnite has a "HyperVOC" mode where the chargers go dormant until they drop below safe Voc, but even the hyper mode has a never exceed limit. Yes. Most of them. A 500A shunt shouldn't even be run at 500A. 400A max continuous...

I'll take a moment to shit on Pylontech before they are mentioned. Stupid 15S batteries.

Sorry. This really pisses me off. I'm calling bullshit on this dismissive comment. Shame on you. You're faulting an installer for a design flaw that can produce 400VAC where the unit is supposed to provide NO voltage to when grid is not present. Period. That's a UL requirement. It's not...

Chase flagged the purchase and refused to process it. Yes it is. Steps 1-4 often happen almost instantaneously. I have received MULTIPLE fraud calls from Chase. NEVER have they ever asked if I COMPLETED this purchase. They asked me "This is so-and-so with the Chase fraud divisions calling...

Unfortunately, your clamping method may have contributed to failure, and if I was Xuba, I would claim that was the cause. You ensured the clamping force was concentrated at the edge of the cells. Had you simply placed plywood or some other rigid plate at each end of the battery, there would...

I'll state explicitly. As the thread starter, and stats as "Papa Smurf"... I have never received a penny from anyone concerning Victron products. They have only cost me money and a tremendous amount of my time.

Is the thinking when your servers are in China, you're not worried about a cyber attack on North America? :P

We're all card carrying members of Solarholics Anonymous.

Dear Mr. @timselectric, I feel you have failed to express the significance the situation adequately. I have revised the quoted text accordingly. Regards, Papa Smurf

I don't care how much meth or crack you consume, you won't be able to do it fast enough.

Late to this party... Not ground mount as installed, but would work on ground. No comments on my fancy method of getting the wires into the container... Wires pinched between stationary rubber and metal don't abrade, and squeezing them doesn't slow the juice... :p 1/8" angle iron. Ordered...

Wall of text. Good luck!

I got my dad the 18000BTU MRCOOL DIY for his 2S2P garage (2 cars wide, 2 deep) so he and my brother could install it themselves. The only thing they didn't do was the electrical work. They weren't comfortable with it. He's thrilled with it. His only complaint is that the 4' CFL fixture near...

You are being told incorrectly. @SignatureSolarJess said as much. There are likely MANY 12V LFP battery brands that are being used with EG4 hardware that hasn't been explicitly tested by EG4. Would those void the warranty? Only if they damage the equipment in some way. The ONLY way they...

When will you be getting your Cerbo? That's when the real boners hit.

Wife's enthusiasm for X-mas decorations is waning with age. She is within sight of my X-mas apathy... Her enthusiasm was somewhat renewed by the idea of a "popup" X-mas tree... Oh the glory... open the box, tree complete and decorated in 8 minutes! DISASSAPOINTMENT...

Because it's full. The guide is very specific. You NEVER series cells unless you have the BMS installed. period. Good. Wish you had posted sooner. Zero surprise it happened again. Good. wish you had posted at this point. finally a touch of sanity. That's a lot. You're lucky. See...

You can't do what the subject requests on a pure voltage basis. Here are your options: Fast charging to full: 3.55-3.65V/cell - 30 minute absorption time. Slow charging/longer cycle life (98%+ charge): 3.45V/cell - 4+ hour absorption time. Float (95%+): 3.4V/cell The slow charging method is...

No. Get smaller ring terminals. By sandwiching with washers, you increase the resistance with the washer between the terminals.

Drop the politics

I can be an arrogant ass, and I tend to be very blunt, but I generally recognize when I'm wrong, or when someone else has better information. I can also admit when I'm wrong when given objective data or new experience. He seems incapable of thinking he could possibly be wrong. He seems to feel...

A young guy has a crippling stutter. He contacts a variety of people to see if they can help: A shaman. A psychiatrist. A rabbi. A priest, and a prostitute. The shaman, the psychiatrist, the rabbi and the priest give it their all, but his stutter doesn't improve. Finally the prostitute comes...

I wish people would use measurement equipment properly. This happens often enough: https://diysolarforum.com/threads/induced-ac-on-lifepo4-battery-sungrow-sh5k-solar-hybrid.79011/#post-1013754 If you put an AC voltmeter on a DC source, you get a bad reading. PERIOD. Google this. You'll find...

NFPA NEC 2017+ requires panel mounted on a roof to have module level disconnects, i.e., a disconnect at every panel. This is for the protection of fire fighters engaging in roof operations. Your panels, while not permanently mounted, were still present and represented a potential high voltage...

Having owned 5 RVs, I'm painfully aware of the shit wiring between the converter and the battery, and the resulting voltage drop. I'm also aware of just how fully you can charge a 4S LFP battery at only 13.6V. 13.6V is not a safe voltage. Your grade B cells could have been at substantially...

Overkill is underrated. 😁

8X LF280K "EV, Grade A" cells, bus bars, cell dividers, JBD BMS + UART to USB interface. Order paid for on 1/18/2024 Order shipped 2/28/2024 (was supposed to ship before Chinese new year - about 3 week slip) Order received 3/25/2024 67 days to receive order. The snag was the JBD BMS I...

These are grey market cells. They don't meet some requirement for use in EV. More often than not, it's capacity. It doesn't take much looking on this forum to find that this experience is the norm. We are not being sold premium EV cells that meet data sheets for a small fraction of what the...

Based on this attitude, the answer is no.

I have negative infinity need for this, but I want to buy it. What is wrong with me?

Your inability to interpret basic information and simple arithmetic shouldn't be confused with me somehow being foggy. You know that solar flares aren't magic, right? It's just more sun. The only question is how much and for how long. Can you read or interpret technical data? Where do you...

Those panels have exceeded their flex rating.

I think inappropriate thoughts about my Victron stuff, but "no thank you" to their batteries.

Updating for Shane... Wow. Cell #3 has truly dropped to crap. Evening loads triggered a LVD BMS shutdown. I suspect #3 IR has skyrocketed. The only good news is that the freezer started without triggering the inverter LVD this morning. ? This morning's charging drove cell #3 to HVD very...

https://diysolarforum.com/search/1741225/?q=%22doesn%27t+suck%22&c[users]=sunshine_eggo&o=date 3 of 5 of those results are relevant. :)

HUH? You know I hate to argue with you, but I think we disagree here... They publish two rules, both values are published in the MPPT datasheets: Array must never exceed Voc (100V in this case) even in cold conditions. Array short circuit current, Isc, should not exceed PV input current...

A pure grid tie OUTPUTS the claimed AC power. A hybrid OUTPUTS the claimed DC power, not AC. Big difference. Regardless... I have zero patience or sympathy for someone affected by this "misleading" designation. Read the fucking specifications. If you don't, or you don't understand them, you...

Just read about a feudal uprising where a duke's son was killed by rebels. They used a trebuchet to knock him off the battlements with the only available ordnance: a peasant's decapitated head.

EXCEPT that they have been a substantial and positive contributor to this forum for nearly four years whose gender and profession aren't relevant.

@timselectric - one of the many people on this board I wouldn't argue with, because I'm probably wrong... :p

Just wanted to comment on a couple of the above in case you're not aware: 1) if your hot water heater runs on propane (can't imagine it doesn't), make sure you run it on propane (turn the W/H breaker off). This is an energy hog and will empty your batteries pretty quickly unless you manage it...
