You’re correct. After doing some more research, I realized this will not work because the solar charger will pull 15A max and will overload that 48v 4A power supply. I don't think there's any current-limiting circuitry in there, so if more than 4A draw is sustained, it will eventually go pop...

I’m building a portable DIY power station with 8S LiFePO4 batteries (24v), with a Victron 100V/15A MPPT solar charge controller inside to charge the batteries. However I also want the option to charge this battery pack from the AC wall outlet. Can I wire both the solar panels and THIS 120v AC...

I don't know what equipment is used, so these are rough numbers. 16x 455w = 7280w system you can buy panels yourself for about $0.65/watt after tax 7280w x $0.65/w = $4732 for panels mounting hardware + cables, ~$1500 $16,000 total - $4732 panels - $1500 misc hardware = $9,768 labor...

That comes out to about $1.35/watt for labor, which is a lot. But if you no other options, not much you can do about that. After talking to over a dozen solar companies and getting quotes and negotiating, I find that very few are willing to do labor only. A chunk of their profit margin is in...

Doesn't need to be UL-listed, and no inspection required. Those GTIL inverters looks interesting and cheap. But it looks like batteries can only be used to run house loads, but not export excess in the evening/night time, correct?

I have a coworker that currently has a 40-panel array that's grid tied, and now would like to add 48v rack batteries to the system. Doesn't know which microinverter was installed (I'm assuming enphase). He would like to sell excess stored energy back to the grid but only at peak times. What's...

It's very contradictory that sol-ark would specifically reference Tigo units in the manual several times for RSD, but the DC power terminal can't actually support the CCA power requirement. I live in a California where everything is strict here and I'm a little worried this method won't pass...

I'm also getting a Sol-Ark, and the ONLY solution I found for RSD is going with this Tigo module, CCA, and TAP system if I want to keep the PV array DC-coupled. Your detailed post has helped a lot, so thank you! I'm no solar engineer or electrician, but I think what you might be missing is that...

Which server rack and shelves did you use for these? Looks like a perfect fit for size.

Was one side mounted to a stud and the other just directly on drywall with anchor?

I was considering SolarEver as well for the price. Local installer says they're good, although they only have a 12 year warranty.

I guess this doesn't work in every area, but at least for my area, straight from their website I don't see anything that disallows this. I read that as yes, you can sell back to us at the higher rate I read this as yes, you can use those credits when you need it, like charging a battery ...

There is a difference between bill credits at the end of the month, and "true up" at the end of the year where they pay chump change.

Lots of different answers. Someone be the first to try this!

Here are my utility’s rates based on Time Of Use (TOU): $0.42/kwh - on peak (4pm - 9pm) $0.07/kwh - super off peak $0.07/kwh (12am - 6am) Hypothetically speaking, if I just got 1 solar panel just so utility company can approve NEM to sell back to the grid, would there be any technical or...
