8.5. PV CONNECTION
8.5. 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
≤ 8 kW if string voltage is between 800 V and 1000 V
For this serial inverters, 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.
Warning!
The PV array will generate lethal high voltage once exposed to
sunlight.
Warning!
Make sure the PV array is well insulated to ground before
connecting it to the inverter.
Warning!
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.
Warning!
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.
- Make sure the maximum short circuit current on the DC side is
within the permissible range.
