Hello Y'all
randog311 from Galveston Island in Texas.
I'm fairly new to Solar, I'm learning as much about my System and the workings of SolarEdge Equipment as I can.
I now have a 11.34 kWh System with 38 Mission 345 Watt Panels and a SolarEdge SE10000H HD-Wave Single Phase Inverter.
The System was Commissioned on August 18th, the greatest day of production thus far was on August 23rd 2021 @ 75.08 kWh.
Happy to be here.

Welcome to Solar Panel Talk

Just to be clear I think you are using the wrong terminology when you state you have an 11.34kWh system. I think you mean an 11.34kw system which is still a guess since you also stated you have 38 345watt panels which equals 13110 watt system (38 * 345W = 13100w)

I stand corrected by the Super Moderator, partially a Typo, I meant to Type 11.34kWp, My System was originally to be 36 Panels, 2 additional Panels were added before the System was Commissioned. Even at 36 Panel's... x 345 = 12,320 still is more than 11.34kWp? I wasn't the the one "Entering" the information to the SolarEdge Monitoring Admin Portal. Go Figure? Humans make errors. Here's the Public Link to My Site: https://monitoringpublic.solaredge.c..._US#/dashboard Another thing to consider is the Max Production Bottleneck of the 10K Inverter I have, it can only Export approx. 10,000 Watts regardless of whatever the Perfect Sun Scenario can deliver even if I had the "Maximum Oversizing" of Panels equaling 15.500 Watts was present. The Inverter would simply commence in "Clipping" once the Panel's began supplying more than the 10K Watt Limit.

I believe the limit is due to size of the 10kw inverter. It may only be rated 11.34kw so the increased amount of panel wattage may end up clipping or just not producing what the panel nameplate states. All good.

Not an exact analogy, but hooking an inverter that cannot put out more that the rated power of the array feeding it is a bit like throttling the power output of a sports car. Why ?

Yes, to a degree your analogy is correct, however with with Solar as you know... Not all that Power is on Tap all the time like it is with a Sports Car. With Solar, one of the benefits of over sizing the Solar Array Wattage greater than the Inverter is that (I read this somewhere) smaller Inverters are more efficient and less expensive than there larger counterparts. Also if "Clipping" does occur, usually the production amount gained will be minimal at the cost of decreased efficiency. While "Clipping" is occurring, the duration of Maximum production is increased rather than briefly "Peaked".

I moved all of these posts to a separate thread so the original OP will not be shaken up.

If I may, another benefit of extra panels, is to boost output under clouds (or lately, smoke).
If you have the flexibility of a ground mount with a simple string inverter(s), clipping losses
may be avoided in exchange for a longer productive day, by paralleling strings of panels
of different orientation. Bruce Roe

You May Bruce, nice addition to the conversation. I remember Smokey days having grown up in Southern California. I don't get much Smoke on the Gulf Coast, although the Weather here is much more Extreme at times, "Wind and Storm" Permits and Approval here are a must.
