Based on this attitude, the answer is no.

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...

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...

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.

Overkill is underrated. 😁

@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...

You literally just expressed your lack of common sense. A human BMS has a 100% failure rate. Everything else you said is irrelevant.

You've said your peace. Please refrain from essentially making identical posts in other threads. Cross posting is at a minimum poor forum etiquette. That out of the way... To give you a comparison, a Battleborn user saw his battleborn battery drop to about 50Ah of capacity simply because...

Even then... sanity check it here: https://www.omnicalculator.com/ecology/wind-turbine The arrow indicates the maximum amount of power available in a swept area of moving air. Assuming 30% efficient, 12mph will produce 120W: Shows about 150W - so likely more than 30% efficient, but 120W...

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

Average miles driven per year is about 14,263 miles. If EVs are going to replace gas cars, they will be driven the same way and distances. A model 3 gets 4.56 miles per kWh 14263/4.56 = 3.1kWh or 3.1MWh/year. That's a 25-30% increase.

No. Every time I visit the site, it's with a shortcut that only displays new posts with 0 replies. ;) Of course I pounce on anything with Victron in the thread. :P

Have you been looking in my shipping container? Friends and neighbors? Sure! No problem. People on this forum? Shit no.

Running a 5 ton isn't such a big deal. Starting one is a nightmare. Recommend you investigate installing a soft-starter to reduce surge. https://www.microair.net/products/easystart-368-6-ton-soft-start-motor-starter-for-115-and-230v-ac-motors

There is no such thing as a "Victron Venus." There is a Phoenix. "efficiency" is misleading. It is a MAXIMUM, and it only exists at one point on the power curve - usually about 30% of continuous rating. 100W on a 300W inverter is likely to be at nearly the maximum efficiency. 100W on a 3000W...

My impression of Jakiper on this forum is that they should be avoided. I would throw EG4 a 2nd place with SOK/Trophy mostly tied for first.

I get queasy when the mount is notably more expensive than the panels.

There was a thread discussing it. Basically, the email volume is so large, it's costing him $1,000/month. People are flagging notifications as spam and getting the server blacklisted. It can't be switched off at the server. The forum software doesn't allow it. Given that you've only been...

FWIW, for 6+ years I have worked on HEV batteries with resting voltages as high as 320VDC. I rarely wear any protection as dexterity is needed, and when I do, it's rarely more than 7mil nitrile gloves. There are certain cases where the batteries have high voltage where they shouldn't. In these...

If shading is a factor, orientation matters. A portrait oriented panel can have 100% of its output cut off if ONE entire ROW of cells is shaded. If columns are shaded, panel output will be cut by 1/3 when a single column of cells is shaded. Once the entire 1/3 of the panel is shaded, the next...

Based on my personal situation, the sell back to the utility is so cheap, it's not worth the added costs/complexity associated with the contract with the utility. My AHJ simply requires a NEC 2017 compliant PV installation WITHOUT a permit. Once the utility gets involved, everything has to be...

Open a dispute with your credit card company. Jakiper doesn't get to keep your money just because the shipper they chose lost them.

The above three factors paint a clearer picture. Cheap AiO (Growatt, MPP Solar, EG4, Voltronic, etc.), have a notably higher idle consumption. This translates to higher battery cost and higher array cost because the inverter is consuming more power. These added costs narrow the gap between...

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...
