Multiple Unit Configuration

The Conext SW inverter/chargers supports multiple unit configuration to increase

power output. This gives the system engineer and/or installer more options to

work with when tailoring a system to meet load demands. Multiple inverter/

chargers of different power levels can be installed in a system as stand alone or

in parallel.

In a multiple unit configuration, only two Conext SW inverter/chargers of the same

model can be used. For example, two Conext SW 4024 230 units can be

configured because both units each have a 24-volt rating and a power rating of

up to 3500 watts.

In this configuration, the inverter and charger capacity of a system is doubled. In

the case of two Conext SW 4024 230 units, the inverter power rating doubles to

7000 watts and the charging output current doubles to 180 amps. However, the

AC transfer relay rating of 30-amps remains the same. Inverter/chargers can

operate from different battery banks, meaning each unit is connected to its own

battery bank. However, it is highly recommended to use only a single battery

bank. See “DC Connections for Multiple Unit Configuration” on page 1–30.
