VERSION AND RATINGS There are two standard versions of RICH SOLAR PWM controllers 12V 10A Rated for 12V solar panel (Max. 25V) Rated maximum output current of 10Amp 12V 20A Rated for 12V solar panel (Max. 25V) Rated for maximum output current of 20Amp 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 GASSES. IT IS IMPORTANT THAT EACH TIME BEFORE USING OR CONNECTING YOUR SOLAR CONTROLLER, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY. Make sure you connect the red to the positive on the battery and the black to the negative on battery. Please double check before you connect, connecting to wrong terminals may burn out the controller. Confirm that the power wires are tightened to the correct torque to avoid excessive heating from a loose connection. Refer to battery specification, be very careful not to short circuit to the battery connections. 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. 2 FEATURES AND ADVANTAGES - PWM technology, switching control by MOSFET - Common Positive Grounding connection - High efficiency and low power consumption - Battery type setting and battery condition indication - Smart charging control - Charging time management - LED indication for the battery condition and charging statues - Digital display charging parameters and battery settings - Automatically active to Lithium battery against BMS protection - Thermal protection - Over voltage protection, Short circuit protection, Reverse polarity protection - No sparks - Water proof - Solid-duty cables - Corrosion-resistant terminals and connectors. - Conformal coating supplied to the inside board against moisture - Includes a port for external battery temperature sensor (BTS - optional). - Suitable for most of the rechargeable Lead acid battery, including Flooded (WET), AGM, GEL, Calcium battery and Lithium batteries. - Designed according to CE standard, EMC, FCC compliance.

The LCD also can be treated as an independent voltage meter or thermometer. A voltage less than 11.5V Volts indicates that the battery is discharged and needs re-charging. CHARGING STAGES The unit has a 6-stage charging algorithm. Diagnose* - Soft Charge Bulk Charge - Absorption charge Equalizing Charge* - Float Mode 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. 6 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. Absorption - Constant voltage charging and battery is over 85% for lead acid battery; , LiFePO4 battery and LTO battery will close fully charging after absorption stage, the absorption voltage level will reach 14.4V for LiFePO4 battery; 14.0V for LTO battery. Equalization * - Only for WET battery 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. (LiFePO4, LTO, Gel and AGM battery do not run Equalization charge) Float Charge or Re-Bulk charge - 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 13.8 Volts; if the lead acid battery voltage drops to 12.8V at float mode, it will return to Bulk charge; LiFePO4 and LTO battery have no float mode; if a LIFePO4 battery voltage drops to 13.4V, or LTO battery voltage drops to 13.2V after Absorption stage, they will return to Bulk charge LED INDICATION LED indications LED Color Soft start charging Bulk charge (charged capacity < 25%) Bulk charge (charged capacity < 50%) Bulk charge (charged capacity < 75%) RED ON ON ON ON LCD Display LCD Backlight BLUE FLASH RED FLASH ORG OFF GREEN OFF GREEN OFF White ON ON OFF OFF OFF Normal ON ON OFF ON OFF OFF Display ON OFF OFF ON OFF 7 Absorption charging ON ON OFF OFF ON OFF Float charging ON OFF OFF ON ON ON Solar weak (At dawn or dusk) FLASH OFF Subject to battery voltage In the night OFF OFF OFF Solar good, VB < 3V ON OFF FLASH OFF OFF OFF b01 FLASH Solar good, battery reversed ON OFF FLASH OFF OFF OFF b02 FLASH Solar good, battery over-voltage ON OFF FLASH FLASH FLASH OFF b03 FLASH Solar off, battery over-voltage OFF OFF FLASH FLASH FLASH OFF b03 FLASH Solar good, battery over 65C ON OFF b04 FLASH Battery good, solar reverse FLASH OFF Subject to battery voltage P01 FLASH Battery good, solar over-voltage FLASH OFF P02 FLASH Over Temperature Protection OTP FLASH SPECIFICATIONS 1 Electrical Parameters 1-1 Rated solar panel amps 1-2 Normal input Solar cell array voltage 1-3 Max. solar cell array voltage (output has no load) 1-4 The controller lowest operating voltage at solar or battery side 1-5 Standby current consumption at night 1-6 Maximum voltage drop-Solar panel to battery 2 Charging characteristics 2-1 Minimum battery starts charging voltage 2-2 Soft start charging voltage 2-3 Soft start charging current (50% PWM duty) 2-4 Bulk charge 2-5 Absorption charging voltage at 25 --Gel type battery --AGM type battery (default setting) --WET type battery --Calcium type battery --LTO battery --LFP battery 2-6 Absorption transits to Equalizing or Float condition: --Charging current drops to -- or Absorption charging timer timed out 2-7 Equalization charging active (Only for WET or Calcium battery) --Battery voltage discharged to less than --Automatic equalizing charging periodical 8 10/15/20 15-22 25 8V 5 0.25 Max.
