6kW system in Agoura Hills

[gvl]

The glitchy optimizer has been mostly out all this time. Pretty much clear sky today and direct hit, 70F ambient, I'm seeing 7600-7700W output, I was expecting more like 8000W. Looks like the optimizer is shot?

Upd: just saw 7900W, so maybe not...

The optimizer came back, probably best to wait until the monitoring system is in place before making any conclusions.

My 3.1 kW array was getting clipped by my 3 kW inverter for a solid 10 min straight just a little bit ago; direct sun in a cloudy sky can definitely lead to irradiance higher than the STC conditions which are used to determine the headline DC rating. Don't expect to see that on a clear day though... maximum AC output closer to 8000 W is likely to be more typical.

Another forum member recently had a glitching optimizer too, and although the communication with it was not functional, it was still contributing to the overall system power.

Thanks, this makes sense. Today is a relatively cool day as well, higher temps will surely help to keep the output down.

Did they have to get up on the roof with a voltmeter to confirm the glitchy optimizer was putting power out?

FYI, & FWIW High instantaneous Global horiz. at my location was 1227 W/m^2, for a few min. about 1115 hrs., P.D.T. and past 1150 W/m^2 several times so far today.

I'm up and running! Less than 6 weeks from contract signing. The inverter isn't set up for monitoring yet. Today is cloudy but in direct sunlight I'm reading 10200W real time AC output and it correlates with the utility meter display. Not too bad for a 9kW DC array, is this even real? Looks like one optimizer is glitching, the correct number of optimizers 30 was briefly displayed but now down to 29, something for my installer to look into.

I live in West LA with limited roof space so I'm also considering the LG300. Got a quote for SP of $5.5 Kw so I'm looking for alternatives. Can you pm me installer contact?

Sounds about $2.00/Watt higher than other decent stuff.

I got another quote from the same installer for a similar 34xLG300=10.2kW DC system.

Congrats gvl!

Do you have any close up pics of how they attached the panels to your roof?

Could you PM me your installer's info?

I didn't take the pictures, but they used Quick Mount PV Classic Composition mounts, I don't know if all the screws hit rafters but the way flashing were installed looked legit.

Can you PM their info? I can't yet PM

Wow, great price and nice looking system. Does your installer come down to Orange County as well?

They told me they go as far as Bakersfield, I don't see why they wouldn't come to OC.

That's a fairing large system, Congrat!

Thanks, it is a good size for my 15-16,000 kWh annual usage, still it is not as large as my neighbor's

Well, the panels were installed today. Final inspection and PTO pending. Ended up going with 9kW total at $3.17/watt. LG300s with a SE 10k inverter, P400 optimizers. It took 1 day for 7 people. I'm not a big fan of 1 day projects like this but I think it went reasonably well, but only time will tell of course.
