WARNING
- Risk of explosive gases: working in vicinity of a lead-acid battery is dangerous. Explosive gases develop during normal battery operation. Be certain there is enough ventilation to release the gases.
It is important that each time before using or connecting your solar controller, always read this manual and follow the instruction exactly. - Make sure to connect the red to the positive on the battery and the black to the negative.
- Please double check before connecting. Connecting to the wrong termi-nals may burn out the controller.
- Confirm that the power wires are tightened to the correct torque to avoid excessive heating from loose connections.
- Refer to the battery specifications and exercise caution to avoid short-circuiting the battery connections.
- Accidental ‘shorting’ of the terminals or wiring can result in sparks, causing personal injury or a fire hazard. We recommend covering the panel(s) with a soft cloth to block all incoming light during the installation. This will ensure that no damage is caused to the Solar Panel or Battery if the wires are accidentally short circuited.
- Always install a battery fuse on each circuit, including the solar controller.

Installation
Surface Mount
The quickest and easiest way to mount the unit is to remove the front cover and tap screws supplied to secure it to a flat surface.
Flush Mount
Before using this mounting method, make sure there is sufficient depth behind the controller or in the cavity (refer to diagram below).
Wiring Connections
The Solar Controller has 4 terminals which are clearly marked ‘Solar’ and ‘Battery’.
There is a (12V) and ground (GND) terminal for each circuit.
Refer to the wiring diagram below, please cover the solar panel before connecting cables.
When the connections are completed, the Solar Controller will start working automatically.
Operation – LCD Display
Please check your battery manufacturer’s specifications to select correct battery type. The unit provides 8+1 battery types for selections: LCO, LTO, LFP, Crystal (Lead crystal), GEL, AGM, WET (Conventional flooded lead-acid) and Calcium (Calcium-Alloy Grid) battery plus Custom setting via App.
Press and hold the BAT T. TYPE button for 3 seconds to enter battery type selection mode. The selected battery type will be shown on the LCD meter.
The default setting is LFP Battery, and the controller will automatically memorize your selection.
LiFePO, battery shown on the LCD indicates Lithium Iron Phosphate (LFP) battery.
L TO battery shown on the LCD indicates Lithium Titanate Oxide (Li, Ti5012) battery.
The LCO battery type setting is only recommended when working with 3-series Lithium Cobalt Oxide (LiC002) battery.
Caution: Incorrect battery type setting may damage your battery.
When the controller powers on, the unit will run self-qualify mode and automatically show items below on LCD before going into charging process:
Press BAT T. TYPE button to navigate your desired battery type as below:
Press the AMP/VOLT button again to confirm the selected battery type (it will stay solid). Alternatively, the selection will be automatically confirmed after 3 seconds.
Parameter display for battery or solar side
Once the settings are completed, the solar controller will automatically go into charging process, the LCD displays the parameters of solar input or battery charging acceptance as below:
Press AMP/VOLT button in sequence, the LCD will display in turn with solar input voltage, current, power, kWh, battery voltage, charging current, charged capacity (Amp-hour) and battery temperature (if external temperature sensor connected).
The users can also read the battery voltage as degree Celsius or degree Fahrenheit by pressing BATT. TYPE button for converting.
Alternatively display voltage and FULL when battery is fully charged
You can also 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 can also be treated as an independent voltage meter or thermometer at night.
Charging Stages
- Diagnose*- Only for Lithium battery type, subjected to the Lithium battery initial voltage then determine if going to Soft-start or Bulk charge; if the Lithium battery is protected by BMS, the controller will automatically send the signal periodically to the battery terminals to activate the BMS against protection.
- Soft Charge- When batteries suffer an over-discharge, the controller will softly ramp the battery voltage up to IOV.
- Bulk Charge- Maximum current charging until batteries rise to Absorption level.
- Absorption Charge- Constant voltage charging occurs when the battery reaches over 85% capacity. For lead-acid batteries, LiFeP04 batteries, and L TO batteries, full charging will complete after the absorption stage. The absorption voltage levels are 14.2V for LiFeP04 batteries, 14.0V for L TO batteries, and 12.6V for LCO batteries.
- Equalization Charge*- Only for WET or Calcium battery type, when the battery is deeply drained below IOV or every 28 days cycle, it will automatically run this stage to bring the internal cells as an equal state and fully complement the loss of capacity. (LCO, Crystal, LiFeP04, L TO,GEL and AGM battery do not run Equalization charge).
- Float Charge or Restart Charge* – Battery is fully charged and maintained at a safe level. A fully charged Lead-acid battery (Crystal, GEL, AGM, WET or Calcium battery) has a voltage of more than 13.6 Volts; if the lead-acid battery voltage drops to 12.7 V at float mode, it will return to Bulk charge.
Lithium battery will stop charge after Absorption stage, it will restart to bulk charge if the voltage discharge less than 12.0V for LCO battery, 13.0V for LTO battery, and 13.3V for LFP battery.
