Multiple Unit Configuration

The Conext SW inverter/chargers support 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.

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

model can be used. For example, two Conext SW 4024 120/240 units can be

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

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 120/240 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 1–33.
