Hello,
Asking about Sungrow SG12RT and pairing it with 19 Longi LR4-72HIH-450M and 11 Longi LR4-60HPH-375M.
Max. PV input voltage 1100 V
MPP voltage range 160 V–1000 V
No. of MPPTs 2
Max. number of PV strings per MPPT 2 / 1
Is the 1100V max PV input voltage for the whole Unit, per MPP or per String?
On the website where I order from they say that SG12RT is 12000W. In the manual Max. PV input power is 18000W.
Can I connect 18000W(+20-30%) of panels to this inverter?
The price is about the same for the SG10RT and SG12RT so going down 1-2 models don't save me much money and I might be installing more panels in the future.
