VEIKONG 45kw SOLAR PUMP INVERTER PICTURE:
Quality Control
VEIKONG solar pump VFDs have passed comprehensive test process
during manufacturing.
R&D test: test the hardware and software performance, to make
the design more optimization, makes sure the products have
excellent
performance before production;
Board test: test the performance of every board in our products, to
reduce product defective rate;
IQC: take strict quality inspection for every income components, to
ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the
aging test house at 50°C for 48 hours, to remove every unqualified
products.
Load test: the last and the most important test, add different load
to the solar pump VFDs, test their input and output value, to check
their
working performance. unqualified products will be removed from the
team.
By applying such strict testing process, VEIKONG ensures every
outgoing solar pump VFD has excellent quality.
