1. Attention
Warning：This controller is a high power device, please read the instruction before use, take
extra care when operating.
Safety notes:
☉read the instruction and attention carefully before use
☉Do not disassembly and repair the controller freely
☉Avoid direct sunlight and pay attention to ventilation When installation
☉Install appropriate fuse or circuit breaker on the outside of the controller
☉Disconnect the external fuse or circuit breaker when wiring
☉Be careful to prevent short-circuit when installing the battery
☉To ensure adopt the correct wire diameter, connect firmly, fasten the wire after connection
☉Temperature resistance should be fixed on the battery,the othe end connect to the controller
2. Product introduction
This controller is designed for DC power supply system, small and medium-sized pv
modules power system, using a dedicated computer chip to realize the intelligent control, all
chips adopt industrial level, can be used in harsh environment. Meanwhile system offers
specific indication for the charge, load , sorts of failure and various protections such as short
circuit, over-load, over charge, particular anti-reversed polarity protection and so on, the
controller used computer chip to sample the parameter of the battery voltage, photovoltaic
cell voltage, discharge current and environment temperature. According to the battery’s
character, realized the accurate control to discharge rate, correction of the temperature
compensation through special control model calculation.charging with the intelligent PWM
dim way and charging compensation in accordance with the current temperature of the
battery, compensation factor is 3mv/℃/unit.LCM could show all of the parameters and modes.
Offer as many as five LED adjust way with lattice pattern to guarantee the battery works in
the best status which could lengthen the service life of the battery. The controller has many
work modes to satisfy different customer’s request. Dial switch need to adjust if adopting
different voltage system.
