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.
