Solis inverter -- exceeding the input voltage

buzz11 · 2022-06-27 10:04:26

Is it ok to exceed the input voltage on a solis inverter? I know its ok to exceed the wattage but I'm wondering what happens if the input voltage is exceeded. I've 2 strings fairly max'd out as follows; String 1 has 12 x JA panels at 41.76v each - total 501v String 2* has 16 x JA panels at 41.76v each - total 668v…

I've 2 strings fairly max'd out as follows;
String 1 has 12 x JA panels at 41.76v each - total 501v
String 2* has 16 x JA panels at 41.76v each - total 668v (problem!)
*The 16 panels are different aspects 10 south facing and 6 west facing
The inverter input voltage is 600v so I would be exceeding this by 68v so about 10% over

From what I seen from other posters is that the inverter shuts down completely when over voltage.

Is it 600v per string or in total?
