No. Item Acceptance Criteria
7 Cable hole sealing Cable holes through which cables are
connected are applied with reproof
mud to ensure the sealing performance
of the maintenance compartment and
prevent foreign objects from entering
the maintenance compartment through
the cable holes.
8 Unused terminals and ports Unused terminals and ports are locked
by watertight caps.
9 Installation environment The installation space is proper, and
the installation environment is clean
and tidy.
Use the restop putty delivered with the SUN2000 to ensure the sealing
performance of the maintenance compartment. If you do not apply
restop putty
after connecting cables, the air tightness of the entire system will fail.
6.2 System Power-On
Prerequisites
Before turning on the AC switch between the solar inverter and the power grid,
check that the AC voltage on the power grid side of the AC switch is within the
specied range.
Before the equipment is put into operation for the rst time, ensure that the
parameters are set correctly by professional personnel. Incorrect parameter
settings may result in noncompliance with local grid connection requirements and
aect the normal operations of the equipment.
If the DC is on and the AC is o, the solar inverter reports a Grid Loss alarm. The
solar inverter starts normally only after the fault is rectied.
