Power Conditioning SubsystemSeries SP320
Series SP320 is euipped 3 mode operation ; 1) grid connection, 2)emergency generator interconnection operation, and 3) stand alone operation.
Features
Best PCS for captive consumption solar power system
1) Safety design
We have supplied PCS in which frequency isolation transformer is built for many
years,
as we have given great weight to safety design. This type of PCS is cleary
essential for captive
consumption solar power system for prevention of negative
affect to other facility in case of
unexpected trouble.
Using built-in transformer
type PCS, you can secure the isolation between
AC and DC.
2) Unique operations
Our SP320 series has grid connected operation, emergency power
generator conecction operation(option), and stand alone operation(option).
Impreoved visibility and operability
We adopted full color liquid crystal touch panel reflecting the opinions of
Customers.
Maximize the number of panel in a seris
The maximam input voltage is DC 750V, which is upper limit of DC "low voltage".
We designed PCS considering the ease of installation and also the reduction of
conbiner boxes.
Installation in various environment
We prepared accesories for cold weather area and salt damage area.
