Introduction
The MPPT Controller display is a dedicated display for the ALLTO SOLAR 20A 30A
40A 50A 60A MPPT solar charge controller range. It can be used to read out the
live and historic solar panel and battery data and it can be used to configure
solar panel and battery settings.
Examples of live and historic monitoring:
- PV power, yield, voltage and current.
- Battery voltage, current and charge stage, temp.
- Low/high volt alarm, temp alarm and soc alarm
- Charging stages, boost charger current
- 60-day historical values
- Cumulative historic values over the live of the solar panel and battery

2.1 SOC-stage of charge
The state of charge (SOC) denotes the capacity that is currently available as
a function of rough rated capacity and rate of charging process . The value of
the SOC varies between 0% and 100%.
2.1.1 SOC(state of charge )
If the SOC is 100%, then the battery is said to has full charge, whereas a SOC
of 0% indicates that the battery has zero charge. The value is calculated
based on battery type and charging stages. For lead-acid battery, the initial
bulk charging stage delivers the maximum allowable current into the battery to
bring it up to a state of charge of approximately to 90%. During bulk charging
stage, the battery’s voltage increases to about 14.4 volts for a nominal
12-volt battery.
During Absorption Charging stage, constant-voltage regulation is applied but
the current is reduced as the battery approach 90-98% state of charge. Float
charging, sometimes referred to as “trickle” charging occurs after Absorption
Charging, bring the battery to above 98% state of charge. See Image-A.
2.1.2 SOC (state of capacity)
If the SOC is 100%, then the battery is said to be fully charged, whereas a
SOC of 0% indicates that the battery is completely discharged. The value is
calculated based on the current battery voltage, provided full battery voltage
and zero battery voltage in Section 4.2. Typically, when lead-acid battery has
a full charge and charging is cut off, the battery voltage will drop off and
finally reach to 12.8V-13.2V(depending on battery age). When battery is
completed discharged, the voltage is 10.8V, see Image-B.
Important Note: When battery is under solar panel charging, the stage of
charge value will be displayed in priority; When battery is not under solar
charging, the stage of capacity value will be displayed.
Installation
STEP 1 – Drill
Drill a hole in a mounting substrate as indicated in below figure..
STEP 2 – Wiring
Let the cable pass thru the hole and wire to the port on back of display
STEP 3 – Install
Attach the display outer frame to the hole STEP 4 – Assemble
Connect the cable to RS232 port in charge controller,
Operation
4.1 Using the menu
Four buttons control the display monitor, the function of the buttons depends
on which mode the display is in.
| Button | Function |
|---|---|
| In setting mode | In main screen mode |
| SETUP | -Press and hold for 3 seconds to switch to main screen mode. |
-Short press to store the edited value and quit. -Short press to return to selected description of parameter.
-Short press to stop scrolling underline and enter selected value editing.
-Short press to confirm current value and quit editing.| Press and hold for 3 seconds to switch to setting mode.| Press and hold for 3 seconds to switch to main screen mode.
SELECT| |
SETUP/SELECT| | Press and hold for 3 seconds to switch to history data mode.|
+| When not editing, press to move up the next parameter| Increase backlight
intensity| Move forward date
When editing, press or hold to increment the value of selected digit.
| When not editing, press to move down the previous parameter| Decrease
backlight intensity| Move downward date
When editing, press or hold to decrement the value of selected digit.
***Note: 1. Any selected value can be texted only when the underline stop
flashing.
2. The display will become sleep (decrease backlight intensity to 1) when no
action is detected in main screen display mode for 10 seconds, press any
button to restore backlight.
4.2 Setting Mode
The following summary describes all parameters of the display.
-Press SETUP for to 3 seconds to access those setting and use the + and – buttons to browse them.
-Press SELECT to access desired parameter, the display will underline the number and description of selected parameter.
- In Date and Alarm setting(Multiple Values), the display will scrolling underline selected value. Press SELECT to stop scrolling underline and Press + or – to edit value. Once current value editing completed, press SELECT to confirm and quit. Press + or – to switch value upon underline scrolling. Finally, press SETUP to store the value and quit.
- In basic setting, the display will underline selected parameter. Press + or – to edit value and press SETUP to store the value and quit.
- Press SETUP at any time to store the selected parameter and quit.

03 Full Battery Voltage
The full battery voltage must above this voltage level to consider as 100% full. (Note: the voltage is static battery voltage that battery is not under charging.For example, the12v lead-acid battery voltage raises up to 14.4V when approach 9098% state of charge in bulk stage; when float charging complete, the voltage drop off and will finally reach 12.8V(probably 12.8v-13.2v depending on battery age), here, the full battery voltage is said to be 12.8V).
