GENERAL WIRING INFORMATION
7.7
DC Wiring
Warning! The Inverter battery input is not reverse polarity protected.
Reverse polarity will damage the unit!!
The battery connection leads between the inverter and batteries should be kept to a minimum
length. The inverter comes supplied with pre-fitted battery cables and must not be shortened.
Shortening the battery leads will void the warranty of the inverter.
Before connecting the battery leads to the battery/batteries make sure that the batteries are
connected according to the correct operating voltage for the model of inverter.eg: 48 VDC,
Refer to section 7.8
Connect the Positive (Red) battery lead terminal from the inverter to the positive post of the
battery.
Connect the Negative (Black) battery lead terminal from the inverter to the negative post of
the battery.

Battery Connection Methods
7.8.1
Series Connection
12V + 12V + 12V + 12V = 48V A/h remains at 100 A/h
Series Connection (Voltage increases, amperage stays the same as a single battery)
7.8.2
Parallel Connection
Voltage remains at 12V 100 A/h + 100 A/h + 100 A/h + 100 A/h = 400 A/h
Parallel Connection (Voltage stays the same as a single battery, amperage increases)
7.8.3
Series and Parallel Connection
Voltage increases to 48 V
A/h increases to 200 A/h
2 Strings of batteries in series, connected in parallel
Series/Parallel Connection (both voltage and amperage increase)
