Meidensha SP320 Series Power Conditioning Subsystem

Manufacturer: Meidensha Corporation
Model: SP320 Series

Features

Best PCS for captive consumption solar power system
1) Safety design
We have supplied PCS in which frequency isolation transformer is built for manyyears, 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.
