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.
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.
CTRL: auxiliary control output;
TC: temperature compensation probe input;
S+/S-: solar cells connection;
B+/B-: battery connection;
L+/L-: load connection;
S1: control / setup button;
DS1: mode display;
SC: solar charging indicator;
BS: battery status indicator;
LS: load status indicator.
（Control panel picture）
Off: disconnected solar cells or without enough sun, charge off;
Lighted: sunny and not over charge the battery, charging in progress;
Flashing: sunny, but the battery has sufficient, charge off.
Red flickering: low voltage protection of battery starts , turn off the load output;
Red lighted: battery power is low, to maintain the load output state;
Orangelighted: battery power is in the middle, allowing starting load output;
Green lighted: battery is fully charged to maintain the load output state;
Green flickering: the battery is fully charged; to maintain the load to the output,will close the charging circuit.
Off: load off;
Lighted: load starts;
Slow flashing: load current is too large, such as continuous over-current, getting to the state of protection after a presupposed time;
Fast flashing: load short-circuit or over current time out, system protection has been launched after a certain time, automatically attempt to restart the load, if such overload fault has been ruled out, then enter into the normal working condition.
ⅣMode setting table
|Setting Table of Operation Mode|
|LED display||Working code||LED display||Working code|
|0||Pure charger mode||9||Light-off open + 9 hour delay|
|1||Light-off open + 1 hour delay||0||Light-off open + 10 hour delay|
|2||Light-off open + 2hour delay||1||Light-off open + 11 hour delay|
|3||Light-off open + 3 hour delay||2||Light-off open + 12 hour delay|
|4||Light-off open + 4 hour delay||3||Light-off open + 13 hour delay|
|5||Light-off open + 5 hour delay||H或H.||Manual mode|
|6||Light-off open + 6 hour delay||C||Universal Charger mode|
|7||Light-off open + 7 hour delay||L||Pure light control mode|
|8||Light-off open + 8 hour delay||D||Debug mode|
a) manual mode-Hand（H）:For manual control of the output load conditions, in this mode, in a non-set state (DS1 not blinking) every time you press the Settings button, you can start up or shut down the load, (DS1) decimal point lights or set off that the output state, the load indicator LS indications of the actual output load status (by the battery voltage, overload, short circuit protection system impact, the load is not completely equivalent to setting the output state of the output), the same below.
b) pure charger mode (0): This mode will turn off the load output, but the logic of charging is still valid; if the load is directly connected to the battery, it can still receive power output. Note: The direct way to connect the load to the battery can not be over-discharge protection and overload, short circuit protection.
c) light-control + delayed mode (1-9, 0. -3.): Startup procedure is the same as above. When the working hours of the load gets to the setting time, it is time to shut down the load.
d) pure light-control mode-Light (L): When there is no sunlight, the light intensity dropped to start the point, after the start signal being confirmed by 10 seconds delay of controller; when there is sunlight, the light intensity rise to start point. The controller will delay for one minute to turn off the output signal to confirm closure of the output and at the same time the load stop working.
e) universal controller mode-Current (C): Using this mode can only cancel the optical control, time control function, the output delay and related functions to retain all other functions as a general universal controller(buttons control the load through output on or off).
f) debug mode-Debug (D): used for system debugging, the same as pure light control mode, only the delay of the judgment output light signal control (1min/10s) has been canceled in order to retain all other functions. No light signal is connected to the load, bright signal that is off-loaded for easy installation check the correctness of system installation.
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.
