Introduction
The ePOWER 20 & 30 Amp Solar Charge Controllers are common positive PWM charge controllers with
built in LCD display and USB ports. The multiple load control modes enable them to be widely used on
caravans, camper trailers, boats, portable solar panels, commercial street signs etc.
The ePOWER Solar Charge Controller range is built for the toughest Australian conditions using
professional level components which have resulted in eciency, increased reliability and performance.
Standard features of the ePOWER include automatic overload, low battery, overheating and built-in short
circuit protection. The ePOWER Solar Charge Controller is well equipped to give you lasting trouble-free
operation.

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.

Mounting the Device
The Solar Controller is best mounted on a vertical surface for maximum cooling eciency. To mount
the unit, use self-tapping screws and mount the unit via the four screw holes supplied and ax to a at
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 rst, in order to allow the controller to recognize the system voltage.
4. Power up the controller and conrm 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 eld,
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 “oating”. 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 owing 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 xed at 25°c without the RTS installed).
• Multiple protections against reverse polarity, short circuit, over temperature, over voltage, etc.
• IP Rating: IP30
