Pre Installation Information
Batteries
Before installing your Sine Wave Inverter, it is important that you have appropriately sized batteries. A battery that is too small
will not allow the inverter to perform to its full specification. Battery performance will vary between different styles of batteries.
For example, a Deep Cycle battery will tolerate deep discharges on a regular basis much better than a cranking battery, whereas a
cranking battery may provide higher voltage when high battery current is being drawn (eg, when your inverter is starting a motor
or Television).
The table below gives a guide to the minimum battery capacity required:

Battery Terminology
I = Current
This is the measure of electrical power flowing. This is expressed in Amps. For example,
I = 6A
means 6 Amps.
Ah = Ampere Hours
This is the amount of energy a battery can store. In theory this means that a 200 Ah battery could supply 1 Amp for 200 hours.
Alternatively if an appliance draws 2 Amps for 4 hrs then it has used 8 Ah.
CCA = Cold Cranking Amps
This is the maximum amount of current that the battery can supply for a short period of time.
NOTE:
Batteries joined in series (+ to -) will increase the voltage but not the Ah. Batteries joined in parallel (+ to +, - to -) will
increase the Ah but not the voltage.
For example: 2 x 12V / 200 Ah batteries joined in series = 24V / 200Ah
2 x12V / 200 Ah batteries joined in parallel = 12V / 400 Ah
Electrical Requirements
•
DC Input voltage of the inverter must be the same as the battery bank voltage. Please see specification for your model.
•
DC cabling must be connected to the correct polarity terminal of the battery bank (Red = Positive, Black = Negative).
•
It is not recommended that the DC cables to the inverter be extended. If this is necessary then you will have to increase the
DC cable size. Consult your supplier/installer for this calculation.
