Important Safety Information

This controller is base on solar panel feature researching, if use other power supply
1
instead of solar panel, the controller may cause fault.
It is better to install controller in the room, if install the controller outside, please keep
2
the environment dry, avoid direct sunlight and waterproof well.
The controller will be hot in process of working, please keep the environment
3
ventilation, away from flammable.
The Voc of solar panels is high (especially 24V/48V system, please take
4
care.
The battery had acidic electrolysis, please put on goggles during installation. If you
5
accidentally exposed to electrolysis, please rinse with water.
The battery has huge power, forbid any conductor short circuit the positive and
6
negative poles of battery. Suggest to adding a fuse between battery and controller.
(Slow motion type, the action current of the fuse should be 1.5 times rated current of
the controller)
Please install the controller in a place where children can not touch.
7
The suggest of using
The controller could detect the temperature of environment to
1
adjust the voltage of charging, so that the controller should be
closed to battery as near as possible.
Recommend system current density of cables less than 3A/mm
2
selection will increase the system consumption, even burning.
Try to use multi strand copper wire in order to connecting with the terminal firmly.
3
Loose power connection and/or corroded wires may result in resistive connections
that melt wire insulation, burn surrounding materials or even cause fire.
Please keep the battery full charged (one time each month at least), or the battery will
4
be destroyed.
This product have limited solar panel input power function, in theory,
5
no matter how much power of solar panel input, the controller will
limited the input power under rated power, but must pay attention to
the following two points:
The short circuit of solar panel less than rated current of controller.

The Open Circuit Voltage of solar panel increased with decreasing temperature,

please ensure in any case, the Open Circuit Voltage of solar panel array will not

exceed 100V, otherwise it will trigger protection or damage to the controller.
Controller Fixed
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.
Please select correct screw to fix the controller on the wall or other platform. Screw
M4 or M5, Screw cap diameter less than 10mm.
Please reserve enough space between the wall and controller, to allow for cooling
and cable connection.
The mounting holes distance is 189mm*85mm，diameter of hole is 5mm。
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
