1 General Information
1.1 Overview
MSC-N series is a new generation of the solar controller with a two-way load output.
The two-way load output voltage can be switched to 12V or 24V DC freely by an
enable switch. According to the battery voltage, the two-way load output voltage can
be turned off in stages to ensure the load1 output. The two-way load output adopts a
high-efficiency buck-boost conversion circuit, which greatly reduces the invalid loss of
the battery and improves the service time of the battery.
The MPPT charging technology can fast track the max power point of solar panels in
any situation and obtain the maximum energy in real-time. It can increase the
utilization ratio of solar energy by 20%-30% compared with the PWM charging
method. Charging current limit, charging power limit, and high temperature charging
power automatic reduction of function, fully ensure the system stability of access to
excess PV modules and high temperature running. Adaptive three-stage charging
mode and comprehensive electronic protections such as over-charge, over-
discharge, PV & battery reverse polarity, etc. effectively ensure the power supply
safer, more stable, and more durable. MSC-N series controllers are most suitable for
applications in the field of security monitoring, RV, and household system, etc.
