paralel PV strings connected to one (1/1) input in solar inverter

[szczepan]

Hi guys !

Is it safe to solar inverter to connect solar array that is capable of delivering much more current than typical 13A?
I am planing to connect 3 PV strings in paralel to one (1/1) 13A input of solar inverter. Are there any dangers to solar inverter (other than max power clipping)?

You will benefit from extra production in the morning, evening, and low sun days.
But it will clip the input to 13a , no matter how much sun is available.

I see that you have diodes on the drawing. Replace them with Fuses and you are good to go.

I know that it will clip the input to 13A. I wonder if such setup can damage inverter somehow ?

No
Voltage is pushed. This must remain below limits.
Current is drawn, having more available doesn’t matter. (Other than possible waste)
Just like a receptacle in your house. It has enough available for the vacuum. But a phone charger will only uses what it needs.
