5.6 Electrical Installation
All wiring should b e p e r f o r m e d b y
a qualified and trained person in accordance
with local regulations and procedures.
Modules could be connected in series
t o i n c r e a s e t h e o p e r a t i n g v o l t a g e b y
inserting the positive plug of one module
into the negative plug of another module.
Always ensure that the contact points
are corrosion-resistant , clean, and dr y
before wiring modules. If the polarities
of modules connected wrong, may lead
to irreparable damage. Before modules
connected in parallel, please check the
v o l t a g e a n d p o l a r i t y o f e a c h m o d u l e
array. If the polarity of products is opposite
or Voltage difference greater than 10V
founded after measurement, please check
the configuration of module array before
its access to power grids.
All cables and connectors u s e d t o
