IMPORTANT SAFETY INFORMATION

This section contains important safety information for the Enerdrive ePOWER Solar Charge Controller. Each time, before using the Enerdrive ePOWER Solar Charge Controller, READ ALL instructions and cautionary markings on or provided with the controller, and all appropriate sections of this guide. The Enerdrive ePOWER Solar Charge Controller contains no user serviceable parts. Opening up the controller will void product warranty. See Warranty section for how to handle product issues.

WARNING!
Failure To Follow These Instructions May Result In Death Or Serious Injury

• This controller is designed for indoor use only
• Do not disassemble the controller. Please see a qualified person if the unit requires repairing Lead acid batteries can be dangerous. Ensure no sparks or flames are present when working near batteries
• Eye protection should always be used.
• Given suffhicient light, solar panels will always generate energy even when they are disconnected
• Accidental ‘shorting’ of the terminals or wiring can resuft in sparks causing personal injury or a fhre hazard. We recommend that you cover up the panel(s) to 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 accidentaly short circuited
• Aways install a battery fuse or circuit breaker on each circuit including the solar controller

SHOCK HAZARD. KEEP AWAY FROM CHILDREN!
Avoid moisture ingress. Never expose the unit to snow, water, etc.

WARNING! EXPLOSION HAZARD!

• DO NOT use the Enerdrive ePOWER Solar Charge Controller in the vicinity of flammable fumes or gases (such as gas bottles or large engines).
• AVOID cOvering the ventilation openings. Always operate unit in an open and well ventilated area.
• Prolonged contact to high heat or freezing temperatures will decrease the working life of the unit.

FIRE AND/OR CHEMICAL BURN HAZARD

• When working with electrical equipment or lead acid batteries, have someone nearby in case of an emergency.
• Study and follow all the charger manufacturer’s specific precautions when installing, using and servicing the controller.
• Keep unit away from moist or damp areas.
• Avoid dropping any metal tool or object on the controller. Doing so could create a spark or short circuit which goes through the controller or another electrical tool that may create an explosion.

LIMITATIONS OF USE

• Do not use in connection with life support systerms or other medical equipment or devices.
• Controller is not to be used by persons with reduced physical or mental capabilities or lack of knowledge and experience. Not to be operated or used by children.
• Avoid dropping any metal tool or object on the controller. Doing so could create a spark or short circuit which goes through the controller or another electrical tool that may create an explosion.

Mounting the Device

The Solar Controller is best mounted on a vertical surface for maximum cooling efficiency. To mount the unit, use self-tapping screws and mount the unit via the four screw holes supplied and affix to a flat surface.

Wiring Connections

1. Connect components to the charge controller in the sequence as shown above (1,2,3) and pay particular attention to the “+” and “-”. Please don’t insert the fuse or turn on the breaker during the installation. When disconnecting the system, the order will be reversed, (3,2,1).
2. The battery fuse should be installed as close to the battery as possible. The suggested distance is within 150mm.
3. Always connect the battery first, in order to allow the controller to recognize the system voltage.
4. Power up the controller and confirm that the LCD screen turns on. If the screen does not power up, refer to page 14 TROUBLESHOOTING.
5. The ePOWER Solar Charge Controller is a common Positive Controller.

NOTE: If using an inverter, or have a load larger than the load output of the solar controller, connect the inverter and/or large load/s directly to the battery.

Features

• 4 Stage charging ensures the battery is charged to the optimum level (Bulk, Absorption, Equalisation and Float)
• Advanced MCU control pulse width modulated (PWM) technology
• Programmable for Gel, AGM and Conventional Flooded batteries
• Built in regulator to prevent your battery from being overcharged. Overcharging occurs when the charge voltage is unregulated. This can result in premature battery failure
• In built regulator prevents your battery from being under charged. In the solar energy field, battery undercharging often occurs, especially on some conventional Lead Acid batteries. This unit provides an automatic equalization feature for deeply drained conventional Lead Acid and AGM batteries, as well as providing a cycling automatic equalizing feature every 28 days
• The Solar Controller can be connected to the battery permanently to keep the battery fully charged by using a process called “floating”. This means the controller will stop charging when the battery is full and will automatically start charging the battery as required. This process will also reduce water loss and help prevent the battery from ‘drying out’
• Protects the battery from discharge at night. Under low light or no light conditions the solar panel voltage could be less than the battery voltage. The unit contains a special circuit which prevents current flowing back from the battery and into the solar panel
• LCD display design, dynamically displays device’s operating data and working condition including solar/battery/load information
• Dual USB ports (5VDC/2.4A combined Max output) allow power supply charge for electronic equipment
• Remote Temperature Sensor (RTS) port built-in. Optional sensor probe available PN# EN43-TEMP (Temp compensation will be fixed at 25°c without the RTS installed).
• Multiple protections against reverse polarity, short circuit, over temperature, over voltage, etc.
• IP Rating: IP30
