If you’re a delicate flour you couldn’t handle a suitcase that big anyway.

If you like their output it is a simple matter to chop off the newpowa MC4 and install your own.

Looks like 5 years but the immediate credit is probably better for most folks. https://www.kcgreenenergy.com/blog/how-to-calculate-depreciation-on-solar-panels/

You’re killing me Smalls. Where’s that video ? I’ll have to rewatch Sandlot to keep me busy 😎. https://english-grammar-lessons.com/youre-killing-me-smalls-meaning/

It’s an immediate credit in the year it is installed and operational. Again, in the US, no idea about Spain.

Please move your original post to the Humorless section ASAP 😎.

I don’t think that’s how it works. The credit will carry forward until you owe taxes. Simply reduce withholding and get the benefit ASAP.

All I know, for certain, is that if you exceed max voltage on a Victron MPPT the magic smoke comes out 😎. Although it was an accident it seems I gotta learn everything the hard way. Hyper gimmick may have helped in this moment of stupidity.

Separate MPPT especially if you have panels not all lined up in the same orientation to the sun. You would then have an option to optimize some panels for morning sun and others for afternoon.

Of course that is a deduction, not a tax credit. Tax brackets typically determine which is more valuable FWIW.

If you go that route can you flip over the wireway and punch hole’s through flat metal ? Unused punch outs shouldn’t fail code I would GUESS since all of my electrical boxes have unused punch outs.

Asking for a friend 😎. Obviously a US centric question but with all the threads on what does/doesn’t count I’m wondering if anyone has been audited for the tax credit. If so, was it a question of producing receipts, pictures, or an agent conducting an on site visit ? Inquiring minds want to...

Picking fly poop out of pepper IMHO. Not a significant enough difference to discern.

I have a SW-4048 with SCP that works fine but “The One” might tempt me to upgrade. Or I could go all blue to match my existing MPPT’s. Doing nothing would be smart but I rarely do the smart thing 😎.

I’m also in NW OH and other than the Eclipse day the rain has been pouring. Saturday and early Sunday are your best bet but whenever I get more panels up and wired it rains for a week 😎. Good luck from zip 43440 !

And clearly no one has ever told a fib on the internet. 😎 Remember that this was purchased at an auction so the prior owners use would be impossible to know, clearly. Those electrons don’t leave tire tracks unless they release the magic smoke 😎.

Just stop all tax withholding from your pension and give yourself a raise in take home pay. I always hate to sell something at 50-70% of face value when I don’t need to. I’m not aware of a maximum time limit on carry forward of the credits so that is a good question for your CPA. If they...

Wouldn’t your MP-II’s already pass through power without the xfer switch? Edit: I see that you want to be able to bypass to work on the Victrons. I did basically the same thing with Schneider equipment (CSW-4048) years ago, sans xfer switch, and have not regretted it, yet. Your system, your...

I was wondering how you picked that frequency.

You can add Victron MPPT’s to that list. I’ve not used their inverters. The RFI can be tamed but it’s a DIY thing despite them being aware of the problem.

Nice job guys ! Taming RFI is often a tedious and difficult job. Here is a good reference piece from Jim, K9YC for anyone interested : http://www.audiosystemsgroup.com/RFI-Ham.pdf

Agree with the above ⬆️ Although your current setup won’t likely generate more than 40A at normal charging voltages for a 48V nominal battery I wouldn’t step down in wire and fuse size in case you or someone else add panels in the future. And you typically want 25% headroom as well.

You could say that about most thread posts on the forum. If YOU don’t care just move on to the next thread. Those who DO care can continue the discussion.

I’ll guess the structure is more of a concern than the bolts. As pointed out the static load will be different but wind loading should be greatly minimized in your use case. Give it a go and let us know how it works out 😎.

My best guess on the 48V problem is this : Your 48V nominal battery will be over 56V while charging. At max temp your 3s panels will put out a minimum PV voltage of 51.8V if I’m reading your results correctly. I believe the Victron needs to see 5V over charging voltage to function...

Jeez, almost 24 hours later and no video ? WTH ??

If that water bottle is not UL listed your AHJ will never approve the install. 😎

Already being discussed here : https://diysolarforum.com/threads/eg4-indoor-280ah-48v-wallmount-battery.81738/#post-1055920

Regarding insulation, a thread on the forum years ago discussed how it was more efficient to insulate the exterior of a connex as opposed to the interior. It also maintains the limited interior volume/space. Seems like that will be a piece of the puzzle for you. Unfortunately I’m not versed...

With the wire trough Will shows later in the video multiple batteries could be lined up with a couple of inches between batteries for breaker and switch access while the wire troughs would touch/connect.

Sounds like a great project. You might want to fix that 29,000 sqft in the title. I was really wondering when I saw that 😎.

I’ve got a half dozen of these things laying round so one is always handy and I’m out about $15 total amongst all of them. Here is the resistor I used : https://www.amazon.com/gp/product/B07MW4VHDB/ It’s a low DIY hurdle to clear 😎

This is what I made years ago for Anderson SB50’s. One side is a resistor, the other is just a piece of wire appropriately spaced and secured to a piece of scrap wood. Just hold the APP connectors on each side for a bit and then plug them together. Aint pretty but it works 😎.
