2.Installation
Install:
Ready tools and cables. Encourage you to matching the right cables. Ensure that the current density  
Install the controller into a fixed vertical plane. See section 5 of the pore size and pore spacing. In order to ensure a good thermal control conditions, please set aside each 10cm below the controller space.
As shown on the right, connect the (1) Load, (2) Battery and (3) Solar Panel to the controller according to the order of (1) (2) (3). Pay attention to the load, battery, solar panel and controller of same polarity.
Put into the external temperature sensor on the left of the controller (probe port). The temperature sensor should be similar space with battery. (Otherwise, the controller will control the parameters of all wrong temperature compensation.) 
If you have remote monitoring and control function, please insert one end of the included communication wire on the right of the controller (communication port), the other end to connect to the host computer.
Demolition: To prevent accidents, please order the demolition of solar panels, battery and load disconnect with controller. 
Note:Battery polarity will not damage the controller, but you will have a load equipment security risks.
