Risk of inverter damage! Observe the following requirements. Failure to do so will
void guarantee and warranty claims.
• Make sure the maximum DC voltage and the maximum short circuit current of
any string never exceed inverter permitted values specified in "Technical Data".
• Mixed use of different brand or model of PV modules in a PV string or a compro-
mised PV string design composed with PV modules from rooftops of different
orientation may not damage inverter but will cause system bad performance!
6.6.1 PV Input Configuration
In Australia and New Zealand, ensure the DC power for any PV string never exceeds a cer-
tain level with regards to the string voltage to avoid derating:
≤ 12.5 kW if string voltage is lower than 500 V
≤ 10 kW if string voltage is between 500 V and 800 V
≤ 8 kW if string voltage is between 800 V and 1000 V
For SH5.0/6.0/8.0RT, each PV input operates independently and has its own MPPT. In this
way, string structures of each PV input may differ from each other, including PV module type,
number of PV modules in each string, angle of tilt, and installation orientation.
For SH10RT, each pair of PV terminals is corresponding to an independent PV string. PV in-
put PV1 connect to MPPT1 and PV2, PV3 connect to MPPT2. For the best use of PV power,
PV2 and PV3 should be the same in PV string structure, including the type, number, tilt, and
orientation of the PV modules.
For SH10RT, if two PV strings are paralleled externally, the paralleled strings can be con-
nected to PV2 or PV3 only, and the other one cannot be used to connect other PV strings.
