Has anybody isolated the component failure causing the #200 error? I am out of commission until the replacements for my two units arrive.

It looks like great minds think alike... I likewise have been using MidNite's calculator pretty extensively. Thanks for the anti-oxidant recommendation. It usually only hits 30*F once or twice here at night in the winter. The coldest day on record was 33 years ago when it hit 12*F...

Thanks so much...

I need some help in deciding which SCC(s) would be best to utilize on a build. I have two ground arrays... both utilizing 445W panels. ( Voc 49.9V, Vmp 41.2V, Isc 11.42A, Imp 10.82A ) The first array is comprised of 10 panels, and the problem that I have, is that I am limited to...

My thoughts, exactly. And I figured even a bit more conservative, to try and baby these cells into a long and happy life. I doubled the needed bank capacity in order to keep them within a 30-80% operating window. But even treating them with kid gloves, I realize that nothing is guaranteed in...

Ahhh... great minds think alike, my friend!

I am opting for both... compression, and the flexible connectors on my 32 LF280K cells. 1/32" poly insulating panels are sandwiched between each. I'm assembling the second tier of cells today. (Misguided energy policies here in the Great State of Confusion have us experiencing black-outs on...

Welcome to the forum... Quite a few of us have been purchasing these BYD Lifepo4 batteries for many months. You can follow the thread here: https://diysolarforum.com/threads/cheap-4kwh-lifepo4-batteries-from-battery-hookup.1496/ They have been available for purchase without the metal...

Arghhhh..... UPS just delivered my package from OnLine Metals. Two 36" tinned copper bars, both .25" thick x 2" wide. Except that the $100 worth of busbars are missing from the package. The box is crushed and black like it had been ran over, the end torn open, and the box is empty...

Wow... that is certainly much cheaper than the miniature circuit breakers that I chose to utilize. https://www.amazon.com/gp/product/B07351F2J1/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

Very nice ! What are the two gauges of wire?

You are too good... thanks so much!

Justin, how soon will you have the flag battery terminals available for sale? That looks perfect for paralleling my four BYD batteries with 4/0 AWG. Secondly, will you be carrying the Blue Sea ML series link busbars? Lastly, is your manual for the 240A ProLatch down-loadable? Thanks so much...

I've been forced into keeping a scorecard.... so far I've identified Battery Hookup, Infinite Skies, BigBattery, Inc, and Techdirectclub.com as vendors of these batteries. And, I'm sure to be missing a few. Are all of these merchants simply middlemen, or is one perhaps the actual depot that...

No word whatsoever. I emailed and phoned Battery Hookup multiple times, with no response. The first notification that I had was from the trucking firm yesterday. The manifest shows that they have only had it since the 13th.

I've found these to be great from Amazon... I've used the six-hole Tinned Copper busbars, but this ad is for the 4-hole https://www.amazon.com/gp/product/B00TUNHXSK/ref=ox_sc_act_title_1?smid=A2LFR0N15G864V&psc=1 Shipping to Toronto is $5.50 US

Gorgeous homestead! You bring back great memories... I spent three summers, '90-'92 chartering 6-pac fishing between Seward and Valdez. I'd still be there, but my conscience got to me. The family was having to suffer through nine months of winter, so that I could enjoy the three months...

If I had known that there was a local source for these batteries, I would have been all over it. They were just delivered... after being shipped but four days ago from BigBattery.com, Chatsworth, CA. (Ordered 5 weeks ago from Battery Hookup) ....what's wrong with this picture???

The shipping label should shed some light on when they left the vendor... who knows, maybe they have just been sitting at the hub in Sacramento for a month?

BatteryHookup, on Nov 8th.

Steve, I followed the link to the Ebay auction in your post above, and was scratching my head as to why you were opting for the nickel plated steel bars??? And then I read further down where you realized the error. I have received several orders of tinned solid copper bars from Online Metals...

I just received a notification that my three batteries will finally be delivered tomorrow... five weeks since ordering. Sheeesh!

Steve, I share your distaste for being extorted into deleting a review of these batteries that alerted others to ShunBin's fraudulent advertising. Unfortunately, I was outside of Amazon's refund window when we became aware of the 174Ah batteries being used. Even still, I requested a full...

I purchased mine on Nov 8th. If they are being shipped from Tech Direct in SoCal, I would have expected delivery before now, as I am located just north of Sacramento. ????

The portable/intermittent-use nature of your system is the very reason that I did not also list city/county permitting in my comment above... as many areas would not require prior permitting for such a system, but the gaining of the approval from your utility provider lends to the very intent...

As long as your design would ultimately having it capable of connecting to the grid, simply get your power company to sign off on it, and it would qualify.

Cheesy, the solar tax credit law has changed significantly over the years, leading to a lot of confusion regarding if, and when, your solar purchase is eligible for the tax credit. I can indeed take a credit for my system this year. The original Investment Tax Credit (ITC) required that your...

The power 'out' from the BP is energizing the remote power switch on the inverter.

These are currently on sale for Cyber Monday at only $71 each, with free shipping... https://www.amazon.com/gp/product/B07GF5JY35/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

While reading through your post, I envisioned the same solution that George then provided you in detail. As I too am assembling a backup system due to the power outages that have become our new normal here in Northern California. And, like you, it will be prioritizing the energy augmentation...

I have only had positive experiences with Ancor Marine 4 AWG to 4/0 AWG tinned cable. Even the off-brands struggle with matching their prices, while falling far short in matching their quality. https://www.amazon.com/gp/product/B000NI3BOQ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1&psc=1

Victron's solution to allow the continued use of their BP with inverters was dead-simple. We simply do not route the B+ through the Battery Protect, to the DC 'IN', on the inverter. In this way, the heavy current surge to initially charge the capacitors does not flow through the BP, while...

I am beyond happy with my two 400AH units. No one else is currently producing such a solid LifePO4 at this price point... and by utilizing an Amazon Prime credit card, financing is free for 18 months. The closest competitor is offering but bare cells. I do think that ShunBin should be...

Take it from someone who likewise changed gears but a few years ago... it is indeed, never too late. I am 63, and after retiring from a career in law enforcement, I was sitting around getting bored... and so I went back to school and became an RN. I love the work! I wish now that I...
