Installation Options / Instructions
+ INSTALLING THE CHARGER
Installation of this unit will require twin core wiring – and suitable cable
connectors (not included).
Suggest ground circuits can be connected to chassis to shorten cable length.
See specifications page for details.
Any existing cables used in conjunction with this charger are required to be
checked to ensure they are a suitable gauge.
If the gauge does not meet the minimum required specification in table on page
6, please replace them.
- All below fuses are not supplied.
-
Locate where you are going to install the DC-DC charger. Ensure the charger is located in a suitable dry area in the vehicle or caravan.
-
Ensure the charger is securely mounted. Charger can be mounted overhead, vertically or horizontally.
-
Next, measure required cable length from the main vehicle battery through to the location of the DC-DC charger.
-
Ensure ALL cabling meets specification and will not be exposed to excessive heat/moving parts or abrasion.
-
You can connect the optional ACC wire to the ignition of your vehicle via a fuse.
-
Measure the distance from the starting battery to the charger; the distance between the charger and the auxiliary battery; the distance between the solar panel output and the charger. Source cable and terminations to suit. A minimum of 10mm2 , twin-core cable is recommended for this application, twin cable for the solar panel, single cable between batteries and charger ground wire as short as possible.
-
If the charger is located in a camper/caravan we recommend the use of an Anderson style plug between the tow vehicle and the camper/caravan as shown below.
-
Fit Anderson style plug connectors on either end of the twin core cables.
-
Connect the main battery to the charger – make sure polarity(+ & -) are correct.
-
Connect the solar panels to the charger – make sure polarity(+ & -) are correct.
-
Connect the auxiliary battery to the charger – make sure polarity (+ & -) are correct.
-
Ensure unused cables (e.g. ACC wire) are insulated and secured against movement.
-
It is recommended that 60Amp fuses required at both batteries and charger connections and solar connection(+).
-
Check all connections are tight.
+ LOW OR VARIABLE VOLTAGE ALTERNATORS
- If the vehicle is fitted with a low voltage or variable voltage alternator, the ignition sensing wire will need to be connected. This will allow the charger to continue to operate when it senses much lower voltages (as low as 10.BV) from the main battery because it can sense the engine running.
Using 2mm automotive cable, connect the small blue ignition wire from the back of the charger to an ignition power source with a fuse. This can be complicated and may require the assistance of an auto electrician or qualified installer. Once the charger senses ignition power it will start charging.
Suggested installation to vehicle only
It is recommended to install 60A fuses or circuit breakers between the charger and each battery on the (+) wires, located close to the batteries.
Suggested installation to vehicle with caravan
Operating The Charger
+ CHARGER DISPLAY
+ 1. DC BATTERY
Once correctly installed, charger will apply DC charge in priority automatically.
-
Start the vehicle and let it idle.
-
The charger will now recognise that there is charge being applied to the main starting battery.
-
Once the main battery has reached 13.0V the charger will begin to charge the auxiliary battery, once the starting battery has dropped to 12.4V the charger will automatically shut off.
-
The initial default setting is for Lead Lead Acid/ AGM batteries (Select battery type before connecting to auxiliary battery).
-
If you are charging a battery with a different chemistry simply change the battery type by pressing the battery type selector button on the front panel of the charger. (Select battery type before connect to auxiliary battery. Change battery type by a long button press if connected to auxiliary battery already).
-
Once selected, the charger remain on this battery type until it is changed.
-
If the ACC ignition signal is detected, the charger will begin to charge the auxiliary battery once the main battery has reached 11.SV and charger will automatically switch off once the main battery falls below 10.BV.
+ 2. SOLAR INPUT (WORKS ONLY WHEN DC BATTERY INPUT IS NOT AVAILABLE)
- Once the input plug is connected with the solar panel, the charger will transfer to solar charge mode.
- Solar charging requires an input of 13.SV – 25V from solar panels. When available solar panel voltage falls below 13.SV no charge will be delivered to auxiliary battery.
Specifications
- LiFeP04 has 5 charge stages.
WARNING: Failure to use recommended wiring will severely impact on performance of DC to DC charger.
6 Charging Stage
-
Qualification
The charger will test the battery for faults. If the battery voltage lower than 2V, it cannot be charged. Where the voltage is higher than 2V, move to step 2.
If battery voltage between 2V and 12V but fully charged in 5 minutes, charger will identify this is faulty battery and be beeping and POWER ON light flashing. -
Recondition
After the charger identifies the battery voltage, it will start to charge the battery with a small current to activate the battery and improve battery charging efficiency. -
Bulk Charge (Constant Current Stage)
Maximum charge current is delivered to the battery, minimizing charge time. -
Absorption (Constant Voltage)
With the increase of battery voltage, the charging current to the battery will then reduce in order to avoid battery overcharge. -
Full and Analysis
When the battery voltage level reaches a fully charged state, the charging current will drop to 0.
The charger will then shut off all output and measure the voltage drop over 1 minute, before entering the next charging stage. -
Maintenance
The charger will continue sending small pulse current charge to the battery, keeping voltage on about 13.5V. If voltage drops 13V, stages 1-5 will repeat.
Note: The battery charger will analyze the condition of the battery in stage 5 and may not perform this function.
Charging algorithm will change according to battery type.
Charging voltages
NOTE: Battery manufacturers sometimes specify charging voltages.
Not observing their charging instructions may void your battery warranty.
Additional information
DEEP CYCLE BATTERIES
It is expected that this charger will be used to charge a deep cycle type
auxiliary battery.
Deep cycle batteries are designed to provide battery power to run items like
fridges and lighting in caravans and campers.
It is generally accepted that the life of a deep cycle battery can be extended
if it is not discharged below 50% of its full capacity. A fully charged 100Ah
Hour (Ah) battery in good condition should offer 50 amp hours of power without
impacting on its normal life expectancy.
Your average compressor style fridge uses up to 5 amps. Over a 24 hour period
it should use approximately 30 amp hours. Therefore if the 100AH battery is
operating only the fridge (and receives no additional charge) it ideally will
require recharging after 48 hours.
To replenish these 60 amp hours using a 20 amp DC-DC charger will require at
least 4 hours of driving. The last 10-20% of battery charging is slow, the
closer it gets to 100% the slower it is.
Undercharging a battery and discharging to below 50% can severely impact on
life expectancy of most deep cycle batteries.
The readings are taken at room temperature of 26°C(78F); the battery had
rested for 24 hours after charge or discharge.
Voltage reading and specific gravity of electrolyte (lead acid batteries) can
give an indication of your battery’s state of charge.
