situations. Available for PC monitoring and external display unit connecting like MT50 and so on, realizing real-time data checking and parameters setting. Support software upgrade. 1.
② Monitor controller by PC and update controller software via RS485 (RJ45 interface). 1.3 Accessories Instructions 1. Remote Temperature Sensor (Model: RTS300R47K3.81A) Acquisition of battery temperature for undertaking temperature compensation of control parameters, the standard length of the cable is 3m (length can be customized). The RTS300R47K3.81A connects to the port (3th) on the controller. Note: Unplug the RTS, the temperature of battery will be set to a fixed value 25ºC. 2.
Input power (PPV)= Output power (PBat) Input voltage (VMpp) *input current (IPV) =Battery voltage (VBat) *battery current (IBat) Normally, the VMpp is always higher than V Bat, Due to the principle of conservation of energy, the IBat is always higher than I PV. The greater the discrepancy between VMpp &VBat, the greater the discrepancy between IPV& IBat.
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. 1.
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).
ATTENTION: Dégât sur l'équipement! L'égalisation peut augmenter la tension de la batterie jusqu'à un niveau nuisible pour les charges CC sensibles. Vérifiez que la tension d'entrée autorisées de toutes les charges disponibles sont supérieures à 11% à la tension du point d'installation de chargement d'égalisation. ATTENTION: Dégât sur l'équipement! Un chargement excessif et une précipitation de gaz peut endommager les plaques de la batterie et la formation de matières actives dessus.
2 Installation Instructions 2.1 General Installation Notes Before installation, please read through the entire installation instructions to get familiar with the installation steps. Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear eye protection, and have fresh water available to wash and clean any contact with battery acid. Keep the battery away from any metal objects, which may cause short circuit of the battery.

Note: The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires can be used to reduce the voltage drop and improve performance. 2.4 Mounting CAUTION: The controller requires at least 150mm of clearance above and below for proper air flow. Ventilation is highly recommended if mounted in an enclosure.
Figure 2-1 Mounting 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 controller and check the battery indicator on the controller, it will be green. If it‘s not green, please refer to chapter 4.

4 Protections, Troubleshooting and Maintenance 4.1 Protection PV Over Current The controller will limit battery charging current to the Maximum Battery Current rating. Therefore an over-sized solar array will not operate at peak power. PV Short Circuit When PV short circuit occurs, the controller will stop charging. Clear it to resume normal operation. PV Reverse Polarity Fully protection against PV reverse polarity, no damage to the controller will result.
Damaged Remote Temperature Sensor If the temperature sensor is short-circuited or damaged, the controller will be charging or discharging at the default temperature 25℃ to prevent the battery damaged from overcharging or over discharged. Controller Overheating If the temperature of the controller heat sinks exceeds 85℃, the controller will automatically start the overheating protection and recover below 75℃. High Voltage Transients PV is protected against small high voltage surge.
indicators blink. (battery indicator red blink) Load terminals no output voltage match with the controller working voltage. Please change to a suitable battery or reset the working voltage. Remove all faults and click the button to resume to work Over load or Short circuit Remove or reduce the load and press the button, the controller will resume to work after 3 seconds 4.3 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for best performance.
