Product Usage Instructions

Review the manual thoroughly before starting installation.
Ensure that the installation is performed by a qualified electrician for devices with high voltage.
Mount the device away from other items as it will produce heat.
Do not put the device in a landfill as it is considered an environmental hazard.
Prepare a wire cutter for cutting and stripping wires prior to connection.
Use a multimeter to test equipment and verify the polarity of cables.
Wear anti-static gloves to prevent controller damage caused by static electricity.
Use electrical tape to safely insulate spliced or bare wires.
Attach wires to the controller using a common-size screwdriver.

Wire Sizing Recommendations

Please see our recommendations for cable sizing below.
WARNING! Incorrectly sizing your cables can result in damaged equipment and fire hazards. For more information, please see AS/NS 3008.1:2017, or consult with an expert.

DC WIRE SIZING| 40A| 60A| 80A| 100A| 120A| 140A +
---|---|---|---|---|---|---
Wire cross-section area (mm)| 10| 16| 25| 25| 35| 50
Wire AWG| 8| 6| 4| 4| 2| 1

The above recommendation is based on cable lengths of 0-1.8m. If the cable is longer than this, go to the next AWG size for every 1.8m of added length.
Warnings! Review this manual thoroughly before attempting installation. Failure to follow these safety guidelines can result in property damage, personal injury, or worse.

If damaged upon arrival, please contact the vendor for product support.
Beware of any nearby electrical equipment that may interfere with installing this device.
If using solar panels to charge the battery, ensure they are isolated, or covered, before connecting to the battery.
If connecting to a DC/DC charger to charge the battery, ensure that the charger is disconnected or isolated from the house/starter battery prior to connecting it.
Do not be exposed to heat, high voltage, and direct sunlight.
Do not short-circuit the positive and negative terminals.
Do not store the battery along with metal and other conductive materials.
Do not disassemble the battery.
Do not knock, throw, or impact the battery.
Do not throw the battery into the water.
Do not install in under bonnet applications.
Do not install in an engine starting application.

Charging Specific Advice

In order to maximize safety, it is recommended to not charge when the site is unattended.
When charging, keep the battery in a well-ventilated, dry, free of inflammable and explosive materials, and out of reach of children.
Always use a battery charger with a lithium profile that does not exceed the charging specifications of the battery (see page 3).
If you are unsure about which charger to use, please contact Amptron and consider our charger range designed for the batteries.
The charger must not have an equalization setting enabled. If this can be disabled then it needs to be turned off.
When the battery leaves the factory, there is only around 30% capacity in the battery due to freight regulations, please charge the battery before use.

Discharge Specific Advice

If the battery cuts out on low voltage, disconnect the load and charge the battery before reconnecting the load. Depending on the charger brand and model, you may need to apply a secondary source of 12V-14.6V to the terminals to reset the BMS.
A low-voltage cut-off device is strongly recommended if your inverter/loads do not have a low-voltage cut-off. Set to the voltage as shown on page 2 of this manual.
If the battery goes below the over-discharge protection voltage (as indicated on page 3) or the over-discharge protection is activated, charge the battery within 15 days.

Storage Advice

The battery should be charged every 6 months.
Ideally, prior to storage, charge the battery to 70% SOC.
The ideal storage temperature is 20°C – 35°C.
Do not leave a battery in a low state of charge for long periods of time.
If the battery shows signs of deformation, heat or emits smell, immediately discontinue use.

Parallel Battery Connection

For detailed instructions on connecting multiple batteries in parallel, please see our white-paper on the topic via the support section of our website.

Ensure all batteries to be in the parallel configuration have been fully charged individually by the same charger.
Ensure the OCV of each battery is within <0.2V of each other.
After charging, set aside and allow to rest for 2-3 hours.
Utilizing wires of circumference large enough to carry the required current, connect the batteries in the above configuration.
Ensure all connecting cables are of the same length.
Be careful not to reverse-connect the positive and negative.
Ensure correct charge voltage and current are utilized for configuration.
It is prohibited to series a paralleled configuration.
Once in parallel configuration, ensure a full charge is completed a minimum of every 3 months.
Once in parallel, the ‘system must be charged and discharged as if it were a single battery.

Series Battery Connection

Maximum 4 Batteries

For detailed instructions on connecting multiple batteries in series, please see our white-paper on the topic via the support section of our website.

Up to four batteries can be connected in series for higher voltage applications. Alternatively, select a higher voltage battery that Amptron has available.
Ensure all batteries in the series configuration have been fully charged individually by matched chargers.
Ensure the OCV of each battery is less than <0.2V of each other.
After charging, set aside and allow to rest for 2-3 hours.
Utilizing wires of circumference large enough to carry the required current, connect the batteries in the above configuration. Ensure all connecting cables are of the same length.
Be careful not to reverse-connect the positive and negative.
Ensure correct charge voltage and current is utilized for configuration:
- a) Two batteries in series: 28.4V to 29.2V, recommended 28.6V
- b) Three batteries in series: 42.6V to 43.8V, recommended 42.9V
- c) Four batteries in series: 56.8 to 58.4V, recommended 57.2V
Once in a series configuration, ensure a full charge is completed a minimum of every 3 months.
Once in a series configuration, the ‘system’ must be charged and discharged as if it were a single battery.
Consider additional balancers to maintain the individual voltage levels of the batteries. Please get in touch with us for recommended options.
