6.6 DC Cable Connection
Danger of electic shock!
The PV array will generate lethal high voltage once exposed to sunlight.
Make sure the PV array is well insulated to ground before connecting it to the
inverter.
Before connecting the PV array to the inverter, ensure that the impedances
between the positive terminals of the PV string and earth, and between the
negative terminals of the PV string and earth are larger than 1 M Ohm.
Risk of inverter damage! Observe the following requirements. Failure to do so
will void guarantee and warranty claims.
Make sure the maximum voltage of each string is always less than 1,000 V.
•
The inverter enters the standby state when the input voltage ranges between
•
950 V and 1,000 V. The inverter returns to the running state once the voltage
returns to the MPPT operating voltage range, namely, 150 V (only SH5.0RT) /
200 V to 950 V.
Make sure the maximum short circuit current on the DC side is within the
•
permissible range.
Each pair of PV terminals is corresponding to an independent PV string. If two
PV strings are paralleled externally, the paralleled strings can be connected to
PV2 or PV3 only, and the other one cannot be used to connect other PV strings.
(only applicable to SH10RT)
6.6.1 PV Input Configuration
In Australia and New Zealand, ensure the DC power for any PV string never exceeds a
certain 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
