sources that do not meet the requirements to the inverter, otherwise the
following consequences may occur:
● The inverter is not recoverable damage.
● The operation of the machine is unstable, manifested as unstable pipeline
water flow, pump running noise, etc.
6.5 DC Side Connection
Danger
！
When carrying out connection between PV array and inverter, the PV array
should be covered with opaque materials and the DC-SWITCH should be
disconnected, otherwise, the PV array may generate dangerous voltage,
cause casualty. The Non-professionals do not make the connection operation.
Warning
！
Before connecting PV array to the inverter, ensure the earth impedance between PV
array and ground is not less than 1Mohm.
Note
！
●
If there is more strings PV modules in parallel, each string PV module
should be with the same model, the same number of PV modules, the
same inclination angle, the same azimuth angle, and the same
cross-sectional area of the connecting wires.
●
Inspect every system carefully before installation.
