1. INTRODUCTION
Thank you for purchasing a “Power Caddy III ”
Your Power Caddy III is a versatile unit specifically designed to provide power when
normal Utility power is not present or frequently fails. It can provide instant emergency
power for many situations where either power has failed or when a ready source of
portable power is needed for leisure activities such as weekend getaways, camping or
boating activities.
It’s very user friendly and has the added benefit of being clean and noiseless. It requires
virtually no maintenance and is inexpensive to operate.
It has a number of advanced features allowing you to:
✓Have virtually instantaneous back-up power when a mains power failure
occurs –with a seamless changeover.
✓Charge 2 x 100Ah 12V batteries.
✓Equipped with a long design life semi-sealed lead calcium battery. (Optional:
Fully-sealed AGM + Gel deep cycle, high cycle fully-sealed hybrid battery.)
✓Accidentally tip or tilt or turn-over the unit without fear of spilling acid from the
fully sealed internal battery (only possible with optional fully-sealed battery).
Original Lead Calcium battery must stand upright as it is only semi-sealed.
This manual describes the simple steps to use the unit and explains the operation of the
Power Caddy III so you can understand what you can (and cannot) connect to the unit
and what to do if you have a problem.

2. USING THE POWER CADDY III
For how long will you get power back-up?
The back-up time is load related and depends what is plugged into the unit and how
long it needs to operate. See table below:
600 W for 60 min
350 W for 2 hours
250 W for 3 hours
200 W for 4 hours
150 W for 6 hours
120 W for 8 hours
THESE ARE CALCULATED BACKUP TIMES WITH A NEW AND FULLY CHARGED
BATTERY AND MAY VARY WITH ENVIRONMENTAL, BATTERY CHARGE AND
LOAD CONDITIONS. BASED ON 800VA WITH 12V 102AH BATTERY.
Power Caddy III can power an assortment of appliances covering most of the standard
home entertainment and household low power appliances you might want to connect to
it. The more equipment connected to the unit, the shorter the back-up time.

3. CONNECTIONS TO THE POWER CADDY III
Supplied with the Power Caddy III is a 3-pin 15A SA cable with a 3-pin ‘G-ST18i
connector’. This cable is for the built-in battery charger in the Power Caddy III. Connect
this cable to an AC mains wall socket to charge the unit. You should leave the unit
permanently connected. If you wish to disconnect the Power Caddy III, ensure the
battery is “fully charged”. Never leave the unit standing with a discharged battery;
you will damage the battery and void the warranty.
If you’ve decided to take the unit away for the weekend, place the unit where you need
it, plug in your equipment, turn it ON and you’ve got instant AC power.

4. SWITCHES, & INDICATORS
At this point, you’re ready to start using the Power Caddy III.
Step 1 is to connect the Power Caddy III to an AC mains outlet, switch it on to get the
battery charged. Note that all our units are shipped to the customer fully charged.
When you connect mains the charger LED will be stable and once the Inverter picks
up the State of charge it will go into Absorption/Storage Mode, at this stage the
Charger LED will flash.
Check the indicators on the TOP of the Power Caddy III that:
•The ‘Inverter’ LED is lit green
•The “Charger” LED is initially is amber, indicating that the battery is being
charged. When the battery is in Absorption, the “Charger” LED will flash;
once the battery is fully charged, the “Charger” LED will continue flashing
indicating the battery is in storage mode.
For more detailed information on the indicators please refer Annexure 1.
It will take about 6 - 12 hours to recharge the battery.
When charging is complete, you can switch OFF the “Master Switch”. If you’re going to
take the Power Caddy III away for the weekend you can unplug the charger cable and
use the Power Caddy III as and when you need it while camping or for other leisure
activities. If you are using it for home back-up power, you should leave the unit
connected to the AC mains and switched on, so that the battery is always charged and
ready for use.
Step 2. Use the Power Caddy III when and where you need it.
You can now connect the equipment you need to the AC power outlet connector on
the Power Caddy III. You can do this by plugging the equipment directly into the
output socket. Switch ON the unit when ready.
If you’re using the Power Caddy III at home or in the office and Utility power is cut-off,
switch ON the “Master Switch” and the inverter in the unit will immediately start.
In standby mode the AC power will be available to the equipment you’ve plugged into
the AC power outlet.

5. TROUBLE-SHOOTING
6. PRECAUTIONARY ADVICE
The manufacturer has taken all possible precautions to protect this unit against
overload, over temperature, reverse polarity, etc. If excessive overload, excessive
temperature and/or reverse polarity are applied to the unit, the protection circuit will work
but with excessive mishandling they may give in after a while and this can cause
damage to the unit. It is therefore up to the user to connect the correct loads and to use
the unit within the specified parameters.
The user must also ensure that no reverse power is fed back into the output sockets of
the system.
The unit must not be kept or operated in direct sunlight and should never be placed in a
moist or wet environment.
In the case of overload, the Power Caddy III will need to be reset by switching the unit
ON and OFF again.
