Ready tools and cables. Encourage you to matching the right cables.
Ensure that the current density ＜4mm ² that is conductive to reducing
the line voltage drop. Recommended: 30A with 10mm ² cable. Check
weather the installation sites compliance with the relevant safety
requirements. Please avoid the damp, dusty, there is a place flammable,
explosive and corrosive gases use the controller to install.
2
Install the controller into a fixed vertical plan e. 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.
3
A s 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.
4
Put into the external temperature sensor on the left of the controller
(probe port). T he temperature sensor should be similar space with battery. (Otherwise, the controller will control the parameters of all
