60A 48V MPPT solar charge controller 

INTRODUCTIONS:
iTracer-ND is an intelligent,efficient,high-speed solar charge controller with advanced Maximum Power Point Tracking(MPPT) algorithm, which can harvest the maximum power from the solar array to charge battery.It can be applied in the off-grid PV systems up to 3KW,and increase the efficiency up to30%.
Thedie- cast aluminum design ensure higher heat dissipation performance.Electronic protections prevent damageas operating error.RS485Port/Modbus protocol improve extensive communication ability,and programmable parameter make the controller sworking with different battery types.MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of PV array, in order to obtain the maximum solar energy in time, MSRT can guarantee very high conversion efficiency in any charge power, which sharply improves the energy efficiency of solar system. With Modbus communication protocol interface, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, wilderness monitoring system, etc.
All-round electronic fault self-test function and enhanced electronic protection function could furthest avoid damages on system components resulting from installation errors or system failures.

Connection:
1)Battery Connection
Connecting a fuse in series through battery positive (+) in the circuit and the battery circuit fuse must be 1.25 to 2 times to the rated current. Keep OFF before connection. Connect battery positive (+) and negative (-) to battery terminals on the controller in the figure 1-1. Please pay much attention to '+' and '-'.
2)Load Connection
Connecting a breaker in series in the load circuit and the breaker must be 1.25 to 2 times of the rated current. Make it keep OFF state before connection. Connect load positive (+) to 17th port and negative (-) to 14th port on the controller in the figure 2-1. Please pay much attention to '+''-' and confirm the cable is connected tightly and right.
3)PV Array Connection
Connecting a breaker in series in the solar circuit is recommended, and the breaker must be 1.25 to 2 times of the rated current. Keep OFF before connection. Connect solar positive (+) and negative (-) to solar terminals on the controller in the figure 1-1. Please pay much attention to '+' and '-'.
Solar array short circuit protection and the reversed polarity connection will trigger automatically.
