20A 12/24V MPPT Solar Battery Charge Controller

20A 12/24V MPPT Solar Battery Charge ControllerOverview
The Tracer-1215BN is based on common negativedesign and advanced MPPT control algorithm, with die-cast aluminum designfor heat dissipation, products in this series are artistic, economical and practical.
With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of photovoltaic array, in order to obtain the maximum solar energy in time, which remarkably improves energy efficiency. With Modbus communication protocol interface, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, caravan system, street lighting 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)Connect components to the charge controller in the sequence as shown above and pay much attention to the "+" and "-".Please don't turn on the fuse during the installation. When disconnecting the system, the order will be reserved.
2) After installation, power the controllerand check the battery indicator on the controller, it will be green. If it's not green, please refer to chapter 4. Always connect the battery first, in order to allow the controller to recognize the system voltage.
3)The battery fuse should be installed as close to the battery as possible. The suggested distance is within 150mm.
4)The Tracer-BN seriesis a negative ground controller. Any negative connection of solar, load or battery can be earth grounded as required.
When the PV array straight polarity, the actual operation of the PV array must NOT exceed three times of rated charge power, When the PV array reverse polarity, the actual operation must NOT exceed 1.5 times.
