Parallel connected batteries are batteries of the same voltage and rating which are connected positive to positive
and negative to negative. They form a battery bank that has the same voltage as each individual battery. The
ratings of a parallel connected battery bank, in general, are the sum of the individual batteries. For instance, if
two 8D batteries are connected in parallel, and each battery has the ratings given in the paragraph above, then
the ratings for the battery bank become 2100 CCA, 900 minutes RC, and approximately 400 amp-hours.
Inverter AC Wiring Applications
There are many different ways that an inverter can be installed and is probably only limited by ones imagination
and wiring codes. There are only a few types which we will convey to you that use good engineering practices
and will cover most needs in a recreational or service vehicle.
Inverter Only Installation
The term "inverter only" means that the inverter is the only source of AC power on board the vehicle. This type of
installation is typical of a service vehicle which needs AC power to run power tools and other equipment during
the work day and does not require the inverter to operate when the vehicle engine (and therefore the battery
charging system) is not running. The AC power distribution system usually consists of an AC circuit breaker and
one or more receptacles.
Inverter with Multiple AC Power Sources
In an installation where there are multiple AC sources, the system needs to be designed so that one and only one
AC source can be connected to the distribution wiring at any one time. This is to prevent the selected power
source from back feeding one of the other power sources. It may be accomplished by using a manual transfer
switch, or an elaborate automated system which chooses and switches to the best available AC source. A very
simple manual transfer system may consist of a cable which is plugged into the desired AC source. Please note
that in all cases where a transfer switch is used, it must switch both the AC "HOT" and "Neutral". This will prevent
many problems, especially when a Ground Fault Circuit Interrupter (GFCI) is used. Also note that the AC
distribution panel must have an insulated neutral bus. The insulated neutral is a requirement of the Nation
Electrical Code (NEC) Article 551-54(c).
