【MPPT Solar Controller】

1. Feature:
The most important feature of this controller is intelligently tracking input voltage from solar panel, which could let solar panel always work at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller could increase efficiency at 10%-30%.
 
2. Function:
This MPPT controller not only has above mentioned special function, but also equipped with completely protecting and controlling functions:
1) Overcharge protection
2) Over-discharge protection
3) Battery Reverse Current Protection
4) Overloading Protection
5) Short Circuit Protection
6) Reverse Polarity Connection Protection
3.Connection:
(As indicated in Picture )
1)    Connect the “+”, “-” poles of the battery to the controller (3, 4 from left) firmly and correctly. The LOAD green LED is supposed to be on if the connection is right and controller is in good condition. If the LOAD green LED is not on, please check if the polarities of battery connected correctly. Only the connection could be preceded if the LOAD green LED is on.
2)    Connect the “+”, “-” poles of the solar panel to the controller (1,2 from the left) firmly and correctly.
3)    Connect the “+”, “-” poles of the LOAD to the controller (5,6 from the left) firmly and correctly.

1. Product Introduction
MPPT30 controller is a kind of intelligent, multi-purpose solar charge controller. It uses the fixed LCD display, with a very friendly interface; various control parameters can be flexibly set, fully meet your various application requirements. MPPT30 controller has following features:
①    MPPT function: The most important feature of this controller is intelligently tracking input voltage from solar panels, and this can let solar panels always work at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller can increase the generating efficiency of solar panels by 10% to 50%.
②    Vivid LCD screen signal and precise operation
③    Intelligent PWM charging mode with auto temperature compensation
④    Adjustable charging and discharging parameters, and settable load working state
⑤    Different protection function for battery, including protection against reverse charging for battery, battery low voltage protection and protection against battery reverse connection
 
2. Installation
 
Install
Get ready for tools and cables. Advise you to match the right cables. Ensure that the current density <2A/mm² , and that is conductive to reducing the line voltage drop. Recommendation: 30A with 25mm² cables. Install the controller into a fixed vertical plane, and the installing pole diameter is 5, and the pole distance is 178*106(mm). To ensure the good ventilation of the controller, please save 10cm at each side of the controller.
 
Connection:
As shown as the right chart, please connect according to the following order (Connecting the solar panels before connecting the battery is not allowed.)
 

 

 
Firstly: Connect the “+”  “-” on the battery to the corresponding ports on the controller.
Secondly: Connect the “+”  “-” on the solar panels to the corresponding ports on the controller.
Thirdly: Connect the “+”  “-” on the load to the corresponding ports on the controller.
Fourthly: Put the external temperature sensor into the left of the controller (probe port). The temperature sensor should be placed at the similar space of the battery. (Otherwise, the controller will control the parameters of all wrong temperature compensation.)
 
Dismantle
To avoid accident, please dismantle the solar panels first and then dismantle battery.
