You have an 8kw inverter and are you surprised that it does not release 10?

Panels 9.7 and an inverter 8. What's the point?
I did the opposite. I have panels for 7 and the inverter for 8
Thanks to this, I have a reserve, as if I wanted to add panels, and the inverter is not wired at maximum speed.

This is a congratulations on your satisfaction with the set, or do not read more about PV, just use what you have - your mood may be spoiled

It makes a lot of sense. He gets up earlier and produces longer. Voltages for the optimal operation of the inverter, etc.

szczukot wrote:

First of all: yes, it will start earlier and work longer. But the first and last minutes have so little sunlight that probably in the entire production it will not even be 0.01%

szczukot wrote:

Secondly, the optimal operation of the inverter is not at the highest voltages, i.e. adding a large number of panels.

For me, the installation works on average at 630V DC. How many do you have? 850V?

I do not know about the Fronius (from the link), but in Huałej we can switch the max power (factory default: + 10% from the nominal), so theoretically, we do not lose anything from a slight oversizing, because the inverter will process it anyway.

the addition of one or two panels is not a masochistic expense, nor will it worsen the operation of the installation

I have sun2000-5ktl-m0 at home, it produces up to 5.5kW, if I understand your post correctly, can I slightly increase this power?

Check what your reactive power compensation setting is, this feature works wonders. For me, it has reduced the number of exclusions by 3 times.

Tauron suggests changing the settings for reactive power compensation, but I don't know where to change it

Use the built-in app in Fusion Solar, option on the home page -> Me -> Commissioning devices, or use the standalone SUN2000 app.

From the Huawei Store (their Google Play counterpart). Or from apk archive sites like apkstore, apkcombo etc.

For example, in the attachment.
But how and if it works - I don't know. A friend with whom we did an on / offgrid hybrid installation with a warehouse, a meter and a Box has a phone from Huaweia and he downloaded the app, so to speak, "as standard" so that I did not have the opportunity to try it.

To use the first option, I must be at the inverter, because it connects locally

The built-in and the standalone app are the same, they also connect to the inverter.
It is enough to be within the range of your home WiFi, the one you have set on the inverter, using the app, built-in or autonomous, you connect to the WiFi network set on the inverter, then enter the password 00000a (if the installer has not changed it) and you are connected to the inverter.

This is what it looks like.



Once you are connected you will see an options screen.

Of course, on hot days, the inverter turns off several times a day.

And have you checked why it turns off? Review the alarms in the SUN2000 APP to see the reason for the shutdown. If it turns off because the mains voltage is too high, you will do nothing.
