Safety warning
During the installation and usage, please make sure to
obey by the following safety regulations and notes to avoid the
damage to controller.
• There is no maintainable part in the controller. User
must not disassemble or repair the controller without
permission.
• Before installing and adjusting the connection of con-
troller, please make sure to disconnect the connection of
photovoltaic panel and the fuse or breaker around battery
terminals.
• After installation, check all the wire connections are reli-
able to avoid heat accumulation for virtual earth.
1. Product properties
he LMS series intelligent solar controller of Guangzhou
Limu Computer Technology Co., Ltd is equipped with industrial-
grade STM 8 microprocessor to control the charge and dis-
charge process and has perfect and reliable battery charge and
discharge period management. The charge circuit is charac-
terized by high efficiency and low consumption by controlling
the MOSFET of ultralow internal resistance with PWM. This
controller has multiple load control modes and is adaptable to
different industries. The product can be applied to the following
occasions:
