PLEASE KEEP THIS MANUAL FOR FUTURE REFERENCE
This manual contains important safety instructions for your 15A/20A smart solar regulator. Do not operate the solar regulator until you have thoroughly read and understood this user manual.
GENERAL INFO & SAFETY INSTRUCTIONS
- This Hardkorr 6-stage smart solar regulator offers unrivalled quality, durability and value for money. It is simple to operate without sacrificing features or functionality.
- Its large, backlit LCD screen provides useful information relating to power input and battery charge level, and inbuilt LEDs provide a quick-reference indicator of battery charge status.
- This regulator ensures that the power generated from your solar panels is at the right voltage to charge your auxilliary batteries. It has an advanced 6-stage charging algorithm, and contains specific charge programs for a range of batteries including Lithium (LiFePO₄ / LTO), AGM, Wet, Gel and Calcium. Battery type can be set with the push of a button and will be memorised by the regulator..
- Its rugged, high-quality construction means it is also IP65 rated, so will not be damaged by exposure to dust and rain. It contains a host of electronic protection circuits including:
- Reverse polarity protection
- Short circuit protection
- Reverse current protection
- Overcharge protection
- Transient overvoltage protection
- Over-temperature protection
- These circuits will ensure your batteries are charged optimally and protected from damage.
- Inbuilt smart reactivation technology means that this regulator is able to wake up ‘dead’ lithium batteries where the BMS over-discharge protection circuit has been triggered.
WARNINGS
- RISK OF FIRE, EXPLOSION AND BURNS: Working in the vicinity of lead acid batteries is dangerous. Explosive gases can develop during normal battery operation. Be certain there is enough ventilation to release the gasses. DO NOT smoke when in the vicinity of the battery under charge.
- ENSURE the red is connected to the positive terminal and the black is connected to the negative terminal if using clamps to connect to your battery. Connecting to the wrong terminals may burn out the regulator.
- DO NOT use the regulator to charge non-rechargeable batteries; this may result in harm to the user and/or damage to the equipment.
- CHECK the manufacturer’s data for your battery and ensure the maximum voltage of the the profile you select does not exceed the recommended maximum charge voltage.
- CONFIRM that the power wires are tightly connected to avoid excessive heating from a loose connection.
- BE VERY CAREFUL not to short-circuit the battery connections.
- Accidental shorting of the terminals or wiring can result in sparks, causing personal inury or a fire hazard. We recommend that you cover up the panel with a soft cloth during installation of the regulator to block all incoming light. This will ensure that no damage is caused to the solar panel or battery if the wires are accidentally short-circuited.
CAUTION
- The regulator should not be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they are supervised or have been instructed on how to use the appliance by a person responsible for their safety.
- DO NOT alter or disassemble the solar regulator under any circumstances. Incorrect handling or reassembly may result in a risk of electric shock or fire and may void the unit warranty.
- Minimum cable gauge is dependent on the total cable length between the solar panel and battery. Selecting the wrong cable or fuse size could result in harm to the installer or user and/or damage to the battery or other equipment installed in the system. The installer is responsible for ensuring that the correct cable and fuse sizes are used when installing this solar regulator.
- ONLY use this solar charge regulator for charging 12-volt lithium, AGM, wet, gel and calcium batteries.
INSTALLATION & CONNECTION
This product can be permanently attached to any flat surface using four self- tapping mounting screws (not included). Simply mark the area you would like to affix the regulator to according to the above diagram and if necessary, predrill holes for the screws to fasten in.
CONNECTING YOUR SOLAR PANEL & BATTERY
The solar regulator has 4 terminals which are clearly marked ‘Solar’ and
‘Battery’. Refer to the wiring diagram as shown above.
When the connections are completed, the solar regulator will start working
automatically.
OPERATION
Please check your battery manufacturer’s specifications to select correct battery type. The unit has charge programs for six different battery types: Lithium Iron Phosphate (LiFePO4), Lithium Titanate Oxide (Li₄Ti₅O₁₂), Gel, AGM, Wet and Calcium.
When the unit powers on it will run a self-test sequence as follows:
- After completing the self-test the regulator will commence charging.
- Press and hold the button for 3 seconds to enter battery selection mode. The regulator will memorise the selected battery for future use.
- CAUTION: selecting the wrong battery type may cause damage.
- Press the button to cycle through battery voltage (V), charging current (A) and charged capacity (Ah). Note: at night only voltage will be displayed.
- When the battery is fully charged it will alternate between displaying and the charge status every 2 seconds.
- The six LEDs indicate the regulator status and alert to any faults present.
LED INDICATIONS
CHARGE PROGRAMS
This smart solar regulator has a 6-stage charging algorithm.
Diagnose (lithium only)
| The regulator checks the lithium battery initial voltage to determine
whether it should go to Soft start or Bulk charge; if the battery is protected
by BMS, the regulator will automatically send a signal periodically to the
battery terminals to activate the BMS against protection.
---|---
Soft start| When batteries suffer an over-discharge, the regulator will softly
ramp the battery voltage up to 10V.
Bulk charge| The regulator will charge the batteries at maximum current until
they reach Absorption level (85% of total capacity)
Absorption
| Once the battery reaches 85% of total capacity, the regulator will apply a
constant voltage charge. Current will taper off as internal resistance rises.
LiFePO₄, LTO, Gel and AGM batteries will go straight to float charge after
absorption stage i.e. an equalisation charge will not be applied.
Equalisation (Wet/Calcium only)| When the battery is deeply drained below 10V
or once every 28 days, the regulator will run this stage to bring the internal
cells to a state of equal voltage. LiFePO₄, LTO, Gel and AGM batteries do not
run this stage.
Float charge/ 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 13.6 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.

FREQUENTLY ASKED QUESTIONS
Q. Can I connect this solar regulator to an existing battery management
system / DC-DC charger with solar input?
A. If you wish to connect your solar panel via an existing battery management
system / DC-DC charger, you must bypass this regulator. Connect your solar
panel directly to the solar input port on your battery management system.
Always check that the device you wish to use in place of this solar regulator
is rated to handle the maximum current capable of being produced by your solar
panel.
Q. Why am I getting no power through my solar panel?
Check the following:
- Make sure all Anderson connectors are plugged in at both ends.
- Make sure a wire has not been pulled out of an Anderson plug.
- Please ensure the solar regulator is connected directly to a battery (not through any secondary regulator / charger)
(Note: if you need to reset the regulator, you can do so by disconnecting the battery)
Q. Why is my solar panel not producing its rated output?
A. Your solar panel will produce maximum output on a clear (cloudless) day
when the temperature is between 24-28 degrees Celsius. It must also be
connected to a battery that is at less than 80% capacity. Once a battery
reaches 80% capacity, the regulator will gradually reduce the charge current
until it reaches 100%.
