LG 280 Watt and Enphase M215 make a great combination

Cloud edge effect?

I guess that could be it in my case . It stayed on like that for couple of minutes but once clouds rolled in, it went down to about half of that. When I questioned my installer he sent me a picture of the inverter from his previous install, dual 4000TL's showing 4000W with only 3200 DC watts worth of modules each. This is 25% over his rated dc power with Suniva modules. I got a picture I can post but need to get ok from him first. I do understand now why he likes to oversize his inverters.

Lots of clouds but I turned it on while everything was clear above.

Hey dirtysanchez, I know you have got to be excited. Congratulations on you new system!

With the LG 280 watt and the M215 micro's, I have seen clipping only on a couple days. And that is really no big deal since it is so minor. But I would tell someone to check PVWatts before considering using higher watt panels. In my area, and at my azimuth, the 280 watts panels are about as high as you would want to go.

I believe with the LG panels, you could go higher on the derate factor. As I have mentioned, my system continuously shows to be 110 percent or higher than rated output. I bumped my derate factor up .89 in Enlighten, and that got me close to 100 percent. But I have since lowered it to .83.

That is probably a function of positive power tolerance a clear cool day and the TL's are extremely efficient

re: m215s best i've seen is $115.

I am about to begin an installation and am considering a reconfiguration of my system depending on when the LA test lab approves the enphase m250 or aurora 0.3 micro. i talked to the building and safety folks today and they said both products are pending approval. if that happens, i'm swapping out 20 canadian solar 230s for lg280s or 285s (using enphase m250s), and installing 72-cell trina 295w modules paired with the power-1 micros. even off-grid systems (which mine is not) are subject to inspection, they said, which has me wondering if any diy-ers/installers have gone through the trouble to permitting/inspection for small off-grid systems (<5kW)..?

My system set a new daily high output today at 23.4 kWh's.

That was a result of one of the best days this year in TX. Low temps, crystal clear skies, and no humidity.

My system set a new daily high output today at 23.4 kWh's. My microinverters all pegged for about an hour. I was just barely able to see a flat top on my bell curves, but still nothing to be concerned about.

So maybe I will see some clipping this spring as has been suggested. But I can live with that as long as my system keeps setting new daily highs.

It only gets worse till the end of the year from now.

Have you gotten any response? I'm wondering the same here.

thx

Not yet

I have seen claims of these being had for $100 each
If you bought them for that price please PM me where you got them

16 x LG 285s, with enphase M250 inverters. Not sure what else you want to know? Total before credits is about $24K, about $9K after credits.

That does sound good. Keep us updated on your progress.

[t5800512]

I'm wondering what price/system that you are getting. I have been recently quoted on a system with 22 x LG 285 pairing with M250s, but the price is crazy high.

Well, I paid $325 for the LG 280 watt panels, $125 for the M215 micros. Then there was the mounting system, trunk cables, wiring, disconnect, etc. My system cost me around $1.45 per watt. That is with me doing the install my self.

Thank you for the price update. It is great to have those incentives to offset the cost of system.
