Ldsolar MPPT charge controller TD100V mppt solar controller
Ldsolar MPPT charge controller TD100V mppt solar controller

TD100V.


In the design stage of  , various design principles have been considered. They include foot biomechanics and physiological structure development (concerning physical stress and weight points).

1) The controller should be installed well-ventilated place, avoid direct sunlight, high temperature and do not install in location where water can enter the controller.

2) Please select correct screw to fix the controller on the wall or other platform. Screw M4 or M5, Screw cap diameter less than 10mm.

3) Please reserve enough space between the wall and controller, to allow for cooling and cable connection.

4) The mounting holes distance is 189mm*85mm,diameter of hole is 5mm。

5) Aluminum fins for natural cooling, we strong suggest hanging installation, this is better for air flow cooling effect.

Installation of Instruction

Controller Fixed

1) The controller should be installed well-ventilated place, avoid direct sunlight, high temperature and do not install in location where water can enter the controller.

2) Please select correct screw to fix the controller on the wall or other platform. Screw M4 or M5, Screw cap diameter less than 10mm.

3) Please reserve enough space between the wall and controller, to allow for cooling and cable connection.

4) The mounting holes distance is 189mm*85mmdiameter of hole is 5mm。

5) Aluminum fins for natural cooling, we strong suggest hanging installation, this is better for air flow cooling effect.

Controller Connection

« All terminals are in tight status after factory, in order to well connected, please loose all terminals at first.

« The following order of connection please do not free change, the controller have battery voltage auto selection function, or cause system voltage recognition fault.

« Before connection, please confirm the voltage of system fit for our controller, the open circuit of solar panel and maximum power at the using range of controller. 

In order to avoid fault installation, please refer to below procedure

 

1) As figure, first connected the battery to controller correct poles. In order to avoid short circuit, please screw the cable of battery to the controller in advance, then connected to battery poles secondly. If your connection is correct, the LCD displaying will show battery voltage and other technical data. If LCD no displaying, please check the fault. The length of cable between battery and controller as shorter as possible. Suggest to 30CM -100CM. 

If short circuit happened on the terminals of controller, it will be result in fire or explode. Please be careful. (We strongly suggest to connecting a fuse at the battery side 1.5time of rated current of controller.)

2) As figure, connected solar panels with controller correctly, if the connection is successful and sunshine is full, the LCD will show solar panel and an arrow from solar panel to battery will be light, we have below suggestions about solar panels connection.

Risk of electric shock, please pay attention to protection

The max input voltage from solar panel could reach 100v, please try to use series connection in order to simplified cables.

In series connection could get down the current of solar panel, reduce sectional area of cable and voltage drop.

For example: 17V 120Wx2 solar panels charge 12V battery, if we use PWM controller, we have to in parallel connection, the solar panel array voltage is 17V, current is 14A, current density is 3A/mm2. So we need sectional area 5 mm2. If we in series connection solar panels array voltage is 34V, current is 7A, At this time we need sectional area of cable 2.5 mm2, half conductor area reduced than parallel connection.

3) As figure, connected loads with controller correctly. In order to avoiding injury from load voltage, please close to the output of controller with button at first, then connected the load on the controller. The controller do not offer reverse connection protection for load, so please take care, reverse connection for output will be destroy loads.

Attention: If users want to connect inverter or inrush starting current loads, please connected them with battery directly, do not connected them with controller, or the controller load can not be start or destroy.

4) Insert type external temperature sensor: external temperature sensor used for temperature compensation, please closed to battery as nearer as possible, if the temperature sensor do not plug in, the controller will default 25℃.

5) RS485 communication interface: Monitored by professional wire and host computer. (optional)

6) USB output:USB could offer 5VMax 1000mA for mobile, laptop, MP3 and so on. (40A not available USB output at the moment

Warning: Please do not connect USB loads to anywhere, the USB output negative poles is in series with Load negative poles.

 

About ground connection of solar system

Please noted, this solar charge controller designed by all positive connection, all components inside the controller are positive combined together. If your solar system needs ground connection, please let positive ground connection.

Warning: For some force to ground connected system, such as solar communication system, portable solar system, they are negative ground connected, at this time please do not positive connected, or can cause short circuit.
