Battery Information
Battery Bank Sizing
Battery capacity Battery size or capacity is just as important as the battery
type selected for use with the Conext SW. The batteries are the most important
part of your system, so it is recommended that you purchase as much battery
capacity as possible. A large battery will extend running time and ensure that
your inverter/charger delivers full rated surge.
It is recommended to have a minimum battery size of 100 amp-hours (Ah) for
moderate loads (<1000W) and greater than 200 Ah for heavy loads.
See “Estimating Battery Requirements” for information on a more detailed
calculation.
About Amp-hours A number of different standards are used to rate battery
energy storage capacity. Automotive starting batteries are normally rated in
cranking amps. This is not a relevant rating for continuous loads like an inverter.
Deep-cycle batteries use a more suitable rating system such as amp-hours (Ah).
Amp-hour capacity is the number of amps a battery can continuously deliver
during a specified number of hours. It is represented by the product of the two —
amps multiplied by hours.
A battery rated for 100 Ah can deliver 5 amps for 20 hours (5 amps × 20 hours =
100 Ah). Depending on the battery chemistry, this battery can deliver a higher or
lower current for less or more time.
