5.4 Conn ecti on

We strongly recommend connecting a fuse directly to the battery to protect any short circuit at the battery wiring. Solar PV modules create current whenever light strikes them. The current created varies with the light intensity, but even in the case of low levels of light, full voltage is given by the modules. So, protect the solar modules from incident light during installation. Never touch uninsulated cable ends, use only insulated tools, and make sure that the wire diameter is in accordance with the solar charge controller’s expected currents. Connections must always be made in the sequence described below (Figure 3: System wiring diagram).

Figure 3 : Syst em wiring

1st step: Connect the battery Connect the battery connection cable with the correct polarity to the middle pair of terminals on the solar charge controller (with the battery symbol). If the system is 12V, please make sure that the battery voltage is within 10V~16V, else if the system is 24V, the battery voltage should between 20V~30V. If the polarity is correct, the LCD screen on the controller will begin to show. 2nd step: Connect the solar module Ensure that the solar module is protected from incident light. Ensure that the solar module does not exceed the maximum permissible input current. Connect the solar module connection cable to the correct pole of the left pair of terminals on the solar charge controller (with the solar module symbol). 3rd step: Connect loads Connect the load cable to the correct pole of the right pair of terminals on the solar charge controller (with the lamp symbol). To avoid any voltage on the wires, first connect the wire to the load, then to the controller. 4th step: Final work Fasten all cables with strain relief in the direct vicinity of the solar charge controller (clearance of approx.10cm).

5.5 Grou ndin g

Be aware that the positive terminals of the controller are connected internally and therefore have the same electrical potential. If any grounding is required always do this on the positive wires.

Remark: If the device is used in a vehicle which has the battery negative on the chassis, loads

connected to the controller must not have an electric connection to the car body, otherwise the low voltage disconnect and electronic fuse functions of the controller are short circuited.

6.Indi cati on of Statu s

The two-line display indicates all present system values in short form on the top line, and the values are without

units (Volt, Amp, etc) due to a lack of space. The printing above each value serves as a reminder:

State of charg e

SOC

“SOC” means "state of charge" and indicates how much remaining capacity the battery still has. The SOC is never 100% as due to technical reasons it is easier to indicate a two-digit number.

“BAT ” shows t he bat tery 's act ual vol tage . “IN” is the sum of the charging currents flowing into the battery.

“OUT” is the sum of discharge currents flowing out of the battery.

The second line constantly changes its information. All values and system information are indicated alphanumerically. The following displays can only be seen during regular operation (not while programming).

“I accu” is the balance of all charging and discharging currents. As long as the charging current is higher than the discharging current, the value is position, in the opposite case, it is negative.

“I in” shows the charging current at the moment. When the voltage of the battery is getting near the final charge voltage, the solar charge controller will regulate the “I in” in order to protect the battery from being overcharged. The charge current “I in” is lower than the module current.

“Temp” displays the environment temperature of the solar charge controller.

The solar charge controller status such as "Fast charging", "Equal charging”, ”Boost

charging”, ”Float charging” and "No Charging” indicate which stage of charging is in process. After a certain period of time of operation in the “Boost” and “Equal” charging modes, the “Float” charge mode is resumed.

The content displays the current load state, “Load on” means the load has been opened, “Load off” means the load is in a closed state.

Day/Night threshold settings: Press the OK button to enter the menu, press ▲ ▼ to change the value.

The controller recognizes day and night based on the solar array open circuit voltage (only functional in street-light mode). This day/night threshold can be modified according to local light conditions and the solar array used.

Possibilities for programming: 3.0~7.5V/6.0V~15.0V(Default: 3.0V/6.0V).

Low voltage disconnect settings: Press the OK button to enter the menu, press ▲ ▼ to change the value.

Note: 1.The difference between disconnect and reconnect threshold must be at least 20%.

If you wish disconnect at higher state of charge you have to first adjust the reconnect

threshold (as per below) to 20 % above the desired disconnect threshold.

2.When you configure voltage regulation, you will find in this window voltage values instead

of SOC values for programming the disconnection voltage level.

The solar charge controller allows the smallest difference between reconnect and disconnect

is 0.8V/1.6V. If you want to program a high level for disconnection you must first increase

the reconnection level.

Possibilities for programming by SOC: 20%~70% (Default: 30%).

Possibilities for programming by voltage regulation:

11.0~12.5V/22.0~25.0V (Default: 11.1V/22.2V).

8 Safety Measures

We urgently recommend the installation of a safety device on the battery pole in order to prevent damage from

short circuits between battery and the solar charge controller.

8.1 Electronic Short Circuit Safety

An electronic short circuit safety device is built into the solar charge controller and prevents both destruction of

the solar charge controller and the blowing of the safety fuse in case of short circuits on the load terminals. The

second line of the LCD display indicates this error as "Short circuit". After elimination of this fault, the solar charge

controller automatically switches back to normal operation after about 60 seconds.

8.2 Hardware Safety

In addition to the electronic fuse device mentioned above, the solar charge controller has also been protected

by regular fuses which have been rated far beyond nominal currents to prevent false blowing of the fuses during

surges. The safety fuses are wired in parallel. In order to prevent fuses from blowing in the case of high currents

over a short period of time, a high value has been selected. Before the fuses blow, the electronic safety fuse

should prevent any excessive current flow.

9 Mal functio ns and Erro rs

The solar charge controller is protected against damage by various measures. Nevertheless, always take utmost

care in the proper operation of the solar charge controller. Short hints of the malfunctions are indicated with the

help of the LCD display. However, errors are only properly indicated in which the system has been properly

installed. If there are other malfunctions than the ones described below, please check first of all if the solar charge

controller has been connected to the battery, the module and the loads correctly in the right polarity. Afterwards,

check the safety fuses.

The load current is too high and the output is disconnected. Either the whole consumption exceeds the max. discharge currents or the max. Pulse currents were exceeded by using high surge appliances.

Battery has low capacity. To protect the battery, all loads powered by the solar charge controller will be disconnected.

The maximum allowable temperature has

been exceeded. In order to reduce further heat generation the loads are disconnected

automatically. As soon as the solar charge controller has cooled down, normal

operation will resume.

In particular, the recharge process through back-up generators or chargers tied directly

to the battery causes battery voltages higher than 16.5V/33.0V.

• There is no voltage feed from the battery.

• current operating temperature is too high

or too low above/below the operating temperature, causing LCD not to function.

Rem edy

Switch off all loads. Remove the fault, the controller will switch on load automatically after 1 minute.

• Reduce loads or hours of operation of loads

to keep the battery from being discharged

deeply, or increase solar array to add energy to the system.

• Connect all loads through the controller to

avoid strong discharge of the battery.

• It will restore only when the battery being recharged and the voltage reaching the reconnect voltage.

• Check the ventilation at the back heat

sink and clean it if necessary.

• Protect the controller from direct sunshine.

• Reduce warming caused by appliances near the controller.

• Reduce the loads or PV modules.
