12. Checking the controller (fast test) after installed for the first time
a. Select a time of the day with a good sunlight condition, enough for getting at least 17-18Voc
from the solar panel array when it is in open circuit (disconnected from the controller).
b. Emulate a darkness condition by turning over the solar panels so their photocell side points
toward the floor/soil, or by covering them (e.g. with flat pieces of cardboard).
c. Connect both the solar panel array and the battery to the controller, paying attention to their
polarity. The unit should start running in Normal Operating Mode showing the battery voltage
and the AGM symbol (as per the factory default). The battery symbol
flashing all the time (in all the operating modes) to indicate that the unit is running OK.
d. Turn over the solar panel or remove the cardboard slowly, so the photocells side starts getting
sunshine radiation, so eventually you should see the sunshine symbol
eventually since then, its corresponding arrow symbol flashing to indicate a flow of charging
current from the solar panel to the battery.
e. With the display showing the symbols
flashing), an increment of the displayed battery voltage should be expected, even a very small
one. In addition, you should read a charging current in Amps, by pressing the or
being proportional to the sunlight intensity, solar panel size (power), and the state of
discharge of the battery.
f. Optionally, and for a higher reading of the above Amps values, you can connect a DC load
directly to the battery terminals.
g. Finally change the settings according to your systems requirements (e.g. battery type, etc.)
Note or the purpose of this test, make sure the DC-Load port (terminals 5-6) is always ff.
13. Understanding the Unit Error Code or Timer Code:
Code
E01 Battery is connected with the polarity reversed. Connect it properly. See section 3.
E02 Solar panel input current is higher than 30A. Disconnect the panel to reset the error.
E03 DC-Load port is drawing more than 30A of current. Reduce the DC load power. The DC
Load output will resume automatically after few seconds. It is checked every few sec.
E04 Unit has Over Temperature Shutdown. The unit will resume operation automatically
after cools down.
E05 A DC-Load Disconnect occurred because the battery voltage dropped to the
corresponding setting. The DC-Load port output will resume automatically when the
battery voltage rises up to the corresponding DC-Load Reconnect voltage setting.
C00 DC-Load port timers for automatic On/Off are disabled. It can operate only manually.
C01 DC-Load port timers for automatic On/Off are enabled. It can operate manually as well.
