Thank you for the thoughtful replies!
Perhaps it’s better for me to go with a cheaper grid-tied inverter without batteries, plus a separate smaller system in case the grid has outages as @Hedges has pointed out :unsure:. Although, I’d also like the simplicity and flexibility of having 1 large...
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 ...
⚡:oops:
Other than A/C and partial EV charging, you guys must be mining crypto.
PS - congrats on the new home :] just got a house myself, fighting other buyers and interest rates was rough
I’m planning on building a 48v solar system, but tied to the grid to dump excess output or pull from when needed. I’m in southern California, so unfortunately the only approved option is the Sol-Ark AIO inverters. Here’s what I’d like to accomplish below.
when sun is out:
1. power house with PV...
Additional detail and questions:
I’m limited on SW and SE facing roof area. I can only fit 33 panels max. I’ve oversized the array to later add central A/C, electric vehicle, and electric water heater. Currently the most needy appliance is the induction stovetop, which is 240v at 40amps max...
I'm contracting a local solar company to install solar panels only because I'm not ably to physically hold one and climb up a ladder doing this solo. I picked larger higher wattage panels thinking less panels means lower install cost, but they still charge by cost per watts at 0.$70. I'm...
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...
My research has been limited so far, but I got this from Will's website:
"...if you wish to also be connected to grid, and/or backfeed the grid with excess power that your system creates, you need to spend some money and get the right product for the job. You will need a UL listed device that...
Mostly large loads. I'm in California where it's mostly sunny throughout the year. I'm planning for worst case scenario: EV charging, A/C running, cooking on induction stove, and hot water heat pump running all at the same time.
Just trying to see which battery arrangement is best.
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 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...
Yes this is PV labor only, I'd be purchasing all hardware, and also permit costs.
I was initially going with large 450w panels, which comes out to $315 for labor per panel. Since this is a relatively large 15kw system, I asked if cost scales better with larger system but they said it's just a...
I have no other benchmarks to compare to in this area (southern California), all other companies wants to do it from start to finish.
Maybe I just need to go to the gym more ?
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'll be using 8x SOK 48v batteries with a Sol-Ark 15k hybrid inverter. Is there a maximum number of batteries I can hook up in parallel because of any limitations, such as cable or bus bar size? The inverter has 2 battery terminals, and the manual states that 275A of battery charge/discharge if...
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...
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’m building out a system to power my whole house to majority run off grid, but still want to be connected to the grid to pull from if ever needed, and to dump excess production from the oversized solar array. Panels output ~15kw, battery 30kwh, inverter is Sol-Ark 15k which can take both AC or...
What did you order that was damaged?
Something like a pallet of 33 panels would be hard to inspect at delivery. Unless the delivery guy is willing to wait around, it'll take quite a while to unpackage and inspect all 33 panels.
But having said that, I've also seen plenty of threads on here...
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...
This is a screenshot of Signature Solar's very own video on youtube, you can clearly see it has that white breaker. However on the website it seems like the EG4-LL doesn't have the breaker. Which one is correct?
The EG4-LiFePower4 48v seems like it still has it though. But EG4-LL is the higher...
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...
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...
These ZnShine 540W bifacial panels produces an astonishing 540w output for the size. Initially I assumed that this included the backside and ideal conditions, like properly mounting it a couple feet off the ground and snow or white surface. But from looking at the datasheet, it looks like this...
