EXPLOSIVE GASES DEVELOP DURING NORMAL BATTERY OPERATION. IT IS IMPORTANT THAT EACH TIME BEFORE USING OR CONNECTING YOUR SOLAR CONTROLLER: This charger is designed for indoor use only and should never be exposed to rain. Do not disassemble the controller. Take to a qualified person if the unit requires repairing. Lead acid, LCO, LiFePO4, LTO batteries can be dangerous. Ensure no sparks or flames are present when working near batteries. Eye protection should always be used. Never short circuit the battery. Given sufficient light solar panels always generate energy even when they are disconnected. Accidental `shorting' of the terminals or wiring can result in sparks causing personal injury or a fire hazard. We recommend that you cover up the panel(s) with some sort of soft cloth so you can 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. Do not reverse connect the wires to the solar panel or battery. MOUNTING AND INSTALLATION This solar controller is designed to be mounted against a wall, especially for caravan use, out of the way but easily visible, please note, mounted on a vertical surface to optimize cable placement and cooling of the unit, indoor use, protected from the weather. -02- 1. The mounting dimensions Refer to the Fig.1 to know the panel size and depth. Refer to Fig. 2 to get a cavity for flush mounting, make sure there is sufficient depth behind the controller or in the cavity. Fig.1 Fig.2 2. The installation preparation Insert a slotted screwdriver into the slots at the below location of and , turn the screwdriver to separate the surface panel from the basement. Take off the surface panel from the basement, you can see four screw holes on the top face. Fig.3 -03- 3. The installation procedures Please see below steps from 1 ~ 6 Insert the input and output cables and firmly secure the cables to the solar controller via the screws, fit the controller to the cutout and wall, secure the controller to the wall, reinstall the surface panel back to the solar controller. Fig.4 -04- WIRING CONNECTIONS To protect the Battery and the Solar Panel, we strongly recommend that you place an inline fuse on the positive wire on both the "Solar" and "Battery" Circuits. 50A fuse for 40A controller; 40A fuse for 30A controller, (As close to the Battery /Panel as possible). Refer to the below drawing, please cover the solar panel before connecting cables. 50AMP Fig.5 Correct Wire Size Please refer to the wire size chart below to determine the minimum size wire needed for each connection.

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. -09- CHARGING STAGE This solar controller provides multiple charging stages with smart charging algorithm. For Lead acid battery (Crystal, Gel, AGM, WET and Calcium battery): Soft Charge Bulk Charge - Absorption charge - Equalizing Charge* - Float charge For Lithium battery (LCO, LFP, LTO battery) Soft Charge Bulk Charge - Absorption charge Stop and Restart charge* Soft start - When batteries suffer an over-discharge, the controller will softly ramp the battery voltage up to 10V. Bulk Charge - Maximum current charging until batteries rise to Absorption level. For Lead crystal battery type, the charge controller will deliver two step level of Bulk charge, when the first level rises the battery voltage up to14.4V, then switch into the second level of the 10% of the first bulk charge rate, until the Lead crystal battery voltage up to 14.7V. Absorption - Constant voltage charging and battery is over 85% for lead acid battery; the Lithium battery (LCO, LFP and LTO battery) will close fully charged after absorption stage. -10- Equalization * - Only for WET or Calcium battery type, when the battery is deeply drained below 10V 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. (Lead crystal, Gel, AGM battery or Lithium batteries do not run Equalization charge). Float Charge or Re-Start 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 12.7V 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, 13.3V for LFP. Remarks: This controller provides an override function (force output delivery) for some heavily discharged Lead acid batteries (Low to 0V), or for some LiFePO4 batteries which are protected by BMS due to over-discharged. Press BATT / - button for 3 seconds to wake up the Lithium battery (activate the BMS against protection) or override the Lead acid battery.
