General Introduction
CM20S solar charge controller is especially designed by industrial degree MCU SCM
with high-performance and excellent quality, and designed for home solar power
system and solar power station.
Functions:
1) Battery management function:
Over-charge protection and over-discharge protection ensure the normal using
and prolong the longevity of battery.
2) Temperature compensation function:
Auto adjust the setting data of battery management program control parameters
to avoid the battery “under-voltage” in winter and “over-charge” in summer.
3) Multi-protections:
Battery reverse connection, over-voltage and low-voltage protections, solar panel
short-circuit protection, auto. Resume output, and output short-circuit protections.
Model No.
