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 earth (GND) terminal for each circuit. Refer to the wiring diagram below, please cover the solar panel before con- necting 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 6 types of batteries for selection: LiFeP04, LTO, Gel, AGM, WET (conventional lead-acid), and Calcium battery.
Press and hold the BATTERY 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 AGM Battery, and the controller will automatically memorize your selection. LiFeP04 battery shown in LCD indicates Lithium Iron Phosphate battery, LFP battery. LTO battery shown in LCD indicates Lithium Titanate Oxide, Li4Ti5012 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 below items on LCD before going into charging process:
The VOLT / AMP button can be changed at any time during charging process. The LCD also can be treated as an independent voltage meter or thermometer. A voltage less than 11.5V indicates that the battery is discharged and needs recharging.
Charging Stages
Diagnose: Only for Lithium battery type, subject 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 the Absorption level.
Absorption Charge Constant voltage charging occurs when the battery reaches over 85% capacity. For lead-acid batteries, LiFeP04 batteries, and LTO batteries, full charging will complete after the absorption stage. The absorption voltage levels are 14.4V for LiFeP04 batteries and 14.0V for LTO batteries.
Equalizing 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. (LiFeP04, LTO, Gel, and AGM batteries do not run Equalization charge).
Float Mode- Battery is fully charged and maintained at a safe level. A fully charged Lead-acid battery (GEL, AGM, WET and Calcium battery) has a voltage of more than 13.6 Volts; if the lead-acid battery voltage drops to 12.6V at float mode, it will return to Bulk charge; LiFeP04 or LTO battery is set for float voltage at 13.4 Volts; if a LiFeP04 or LTO battery voltage drops to 13.2V at Float mode, they will return to Bulk charge.
