Page 10: Battery Charging Stage
Figure 1-3 Mutil-MPP Curve If the program works improperly after appearing Multi-MPP, the system will not work on the real max. power point, which may waste most solar energy resources and seriously affect the normal operation of the system. The typical MPPT algorithm, designed by our company, can track the real MPP quickly and accurately, improve the utilization rate of the array and avoid the waste of resources. - Page 11 A) Bulk Charging In this stage, the battery voltage has not yet reached constant voltage (Equalize or Boost Voltage), the controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging). B) Constant Charging When the battery voltage reaches the constant voltage setpoint, the controller will start to operate in constant charging mode, this process is no longer MPPT charging, and in the meantime the charging current will drop gradually, the process is not the MPPT charging.

Page 16: Mounting
2.3 Mounting CAUTION: When mounting the controller, ensure at least 150mm of clearance above and below the controller for proper air flow. If mounted in an enclosure, ensure good ventilation condition of the box. WARNING: Risk of explosion! Never install the controller with flooded batteries in a sealed enclosure! Do not install the battery in a confined area where battery gas can accumulate. -
Page 17: Wiring
150mm of clearance is required around the controller for proper air flow. Secure the controller in place using proper mounting screws. 2.4 Wiring ※Please remove the terminal protective cover before wiring. CAUTION: The following connection order is recommended for optimal safety. - Page 18 ATTENTION: N'enchevêtrez pas tous les fils ensemble. Le câble de communication et les fils d'alimentation doivent ê tre aussi é loigné s que possible pour éviter les interférences de transmission du signal de communication. ATTENTION: Le eTracer est un contrôleur relié à la terre sur le négative.

Page 22: Power Up
Solar Module(s) 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. - Page 23 Before switching on, recheck the step of ①～④and make sure all wirings correct, especially ④connected with battery and PV array. Turn on the battery Fuse firstly. Observe if battery indicator light and startup interface work fine or not (Refer to section 4). Always connect the battery firstly, in order to allow the controller to recognize the system voltage.
