Huawei rules problem for SUN5000-150KTL-MG0 with optimizer 1300s

[Timothy]

I tried to arrange string with optimizer by Huawei SUN5000-150kTL-MG0 Datasheet and manual that said I can use 7 string and more ( From my understanding). But in the application show that I need to use minimum string is 9.  How can I solve this problem ? or Is there another way to do it?

For Huawei optimizers, we are strictly applying the rules requested by Huawei.

In this case, they requested between 9 and 12 strings per inverter for the sun5000 series.

Please contact Huawei directly if you think a modification to this rule is necessary.
