12V/24V auto 10A/20A/30A PWM controller LED controller solar charge controller 

Product View:

Solar controller for PV systems, coordination of solar panels, batteries and work load, is a very important photovoltaic system component. It makes the whole solar system work efficiently and safely. Solar street light controller is mainly used for domestic, commercial, factory, transport, pastoral areas, communication and other photovoltaic power systems.

Quick Settings:

1, Controller solidly fixed. 

2, Wire preparation: It is recommended to use multi-strand insulated copper wire. Firstly, make sure the length of the cord, secondly, ensure the installation location in the circumstances, thirdly, try to minimize the connection length to reduce power consumption. According to not more than 4A/mm ² in accordance with the current density of selected cross-sectional area of copper wire, the controller side of the first strip 5mm of insulation should be shucked off.

3, Firstly, connect battery termination to the controller, and then connect to the other ends of the battery. Pay attention to +, -, do not be reverse. If the connection is correct, BS should be lighted, according to buttons to check. Otherwise, the need to check the connection. In case of reverse, will not burn any part of the insurance and damage any part of controller, fuse only as the end protection of a controller itself to protect the amount of internal short circuit damage.

4, Photovoltaic cells’ wires connected, connect solar panels termination to the controller, and then the other ends connected to solar panels. Pay attention to +, -, do not be reverse. If it is a sunny day, charging indicator light should be bright. Otherwise, there is need to check the connection.

5, Load connected: connect the wire of load to the controller output, pay attention to +, -, do not be reverse. Otherwise, it would burn appliances out.

6, Connecting photovoltaic cells and the load wires as followings:

remain a curvature along the wire to prevent the controller from rain water.

Technical Overview - Key Features :

1  Using a single chip and special software achieve the intelligent control.

2  Using of battery discharge rate characteristics modify the discharge control. Final discharge voltage is the control point modified by discharge curve to eliminate the inaccuracies by a simple over discharge voltage. In accord with inherent characteristics of the battery, different discharge rates has the different final discharge voltage to ensure the battery to be used effectively.

3  Over charge, over discharge, short circuit, overload protection, unique input connection-output connection, automatic control and so on; more protection from damaging any parts and burning insurance out.

4  Adopting series connected type PWM as the main circuit, the voltage loss of the charge loop lower nearly half compared with the circuit using the diode's charge reduced; in contrast to non-PWM, the charge efficiency is higher 3% -6%; an increase of power utilization time; normal direct charging; automatically control of float charging make sure the system with long lifespan; accurate temperature compensation.

5  Intuitive LED indicates the current battery status to make sure that users understand the behavior in service.

6  Cancel set point adjustment and control of potentiometer, and use of Flash memory to record the work control points to set the digitization to eliminate the vibration due to deviation and reduce errors and reliable factors by drift and other control points.

7  Using of soft- touch keys is convenient and aesthetic.
