4. POWERING UP

4.1 Connecting the battery

Close the connection to the battery, but DO NOT connect the solar array.
All the icons of the display will now light up:
This is followed by the software version:
In this case the Software-version is 1.1.6
After the software-version has been displayed, the
charger will start the system voltage recognition
phase.
The LCD-screen displays two values:
Left: system (= nominal battery) voltage (12/24/36 or
48V), blinking during the battery recognition phase.
Right: actual measured battery voltage.
In some instances the charge controller might not reflect the correct system voltage (e. g. if the battery
is deeply discharged and the actual battery voltage is far below the nominal voltage). In that case the
system voltage can be adjusted manually, see section 4.2.
If the nominal battery voltage shown is correct, press the SETUP button to accept.
Alternatively, the battery voltage shown becomes final automatically after connecting the PV array,
when PV current starts flowing.

4.2 Adjusting system voltage

a. Press SETUP during 3 seconds: the "Menu" icon will light up.
b. Press the "-" or "+" button several times until
the screen shows "AUto", or a system voltage.
c. Press SELECT: "AUto" or the system voltage will blink.
d. Use the "-" or "+" button to decrease or increase system voltage.
e. Press SETUP to confirm the change, the value will stop blinking,
and the change is made final.
f. Press SETUP during 3 seconds: the display is back in normal. mode and the "Menu" icon will
disappear.
Note: a 36V system will not be detected automatically and must be set with help of the above
mentioned procedure.
