SYSTEM BATTERY VOLTAGE SETTING
Press and hold the
SET UP
button for 3 seconds to go into the system battery voltage setting
mode, press
PV / +
or
BATT / -
button to select your desired system battery voltage 12V, 24V or
AUTO, press the
SET UP
button again to confirm the battery voltage setting.
THE DISPLAY IN SEQUENCE:
SYSTEM BATTERY TYPE SETTING
Please check your battery manufacturer’s specifications to select correct battery type. The unit
provides 9+1 custom battery types for selections: LI-95, LCO, LTO, LFP, Crystal (Lead crystal), Gel,
AGM, WET (Conventional lead acid) and Calcium (Calcium contented) battery plus Custom setting.
To set the battery type, press the
SET UP
button to go into your battery type setting mode, the
battery type you select will be flashed on the LCD meter, the default setting is AGM Battery; the
controller will automatically memorize your battery type setting.
CUSTOM SETTING
This solar controller provides a CUSTOM mode to meet your special battery charging demand, the
users can preset the Absorption voltage level and duration, Equalization voltage level, duration
and periodical cycle, Float voltage level and Reset voltage level for your targeted battery charging
parameters.
Alternatively display Absorption Volage character
AbS.U
and voltage data when going into
CUSTOM mode
The controller will automatically memorize your previous battery voltage setting, If AUTO mode
selected, the controller will automatically detect 12V or 24V battery connected.
LFP battery shown in LCD indicates Lithium Iron Phosphate battery, LiFePO4 battery. LI-95 shown
in LCD indicates the battery profile keeps your LiFePO4 battery charged at 95% LTO battery shown
in LCD indicates Lithium titanate oxidized, Li4Ti5O12 battery.
Press
PV / +
or
BATT / -
button to navigate your desired battery type as below:
Press the
SET UP
button again, the selected battery type will be solid On and confirmed.
Absorption voltage setting range from 13.20V ~ 15.50V, press
PV / +
or
BATT / -
button for once +/-
0.05V variation, press the
SET UP
button again to confirm the absorption voltage level you preset,
then move to next Absorption duration setting.
Alternatively display Absorption Time character

and duration data; Absorption duration
setting lasted from 5 – 500 minutes, press
PV / +
or
BATT / -
button for once +/- 5 minutes variation,
press the
SET UP
button again to confirm the absorption duration setting, then move to next
Equalization voltage setting.
Alternatively display Equalization voltage character
EqL.U
and voltage data; Equalization voltage
setting range from 13.20V ~ 16.2V, press
PV / +
or
BATT / -
button for once +/- 0.05V variation, press
the
SET UP
button again to confirm the Equalization voltage and then move to next Equalization
duration setting.
Alternatively display Equalization Time character
EqL.T
and duration data; Equalization duration
setting lasted from 5 – 500 minutes, press
PV / +
or
BATT / -
button for once +/- 5 minutes variation,
press the
SET UP
button again to confirm the Equalization duration setting and then move to next
Equalization periodical cycle setting.
Alternatively display Equalization periodical cycle character
EqL.P
and cycle day; Equalization
periodical cycle day setting P.7/11 from 0 – 100 days, press
PV / +
or
BATT / -
button for once +/- 1
day variation, 0 indicates no Equalization setting; press the
SET UP
button again to confirm the
Equalization periodical cycle setting and move to next Float voltage setting.
Alternatively display Float voltage character
FLT.U
and voltage data; Float voltage setting range
from 13.00V ~ 14.00V, press
PV / +
or
BATT / -
button for once +/- 0.05V variation, press the
SET UP
button again to confirm the Float voltage and then move to next Reset/Rstart setting.
Press
PV / +
button in sequence, the LCD will display in turn with solar input voltage, current,
power and kWh.
Press
BATT / -
button in sequence, the LCD will display in turn with battery voltage, charging
current, charged capacity (Amp-hour) and battery temperature (if external temperature sensor
connected)
The users also can read the battery temperature as degree centigrade or Fahrenheit degree by
pressing
SET UP
button for converting.
Alternatively display voltage and FUL when battery is fully charged
Alternatively display Reset/ Restart voltage character
rST.U
and voltage data; Reset voltage setting
range from 12.50V ~ 13.50V, press
PV / +
or
BATT / -
button for once +/- 0.05V variation, press the
SET UP
button again to confirm the Reset / Restart voltage and all settings will be automatically stored.
You also can visually monitor your battery charging condition for each battery; there is an LCD bar
to show the percentage of charge, you can easily see the battery is charged to 25%, 50%, 75% or
100%, and also roughly match each charging stage of Soft-start, Bulk, Absorption and Float.
The LCD also can be treated as an independent voltage meter or thermometer at night.
LCO BATTERY TYPE SETTING IS ONLY RECOMMENDED WORKING WITH 3-SERIES LITHIUM
