Quick Answer
Sol-Ark units can be connected for additional power, but this requires specific configuration and equipment.
Sol-Ark Parallel Operation
The Sol-Ark hybrid inverter, including the 12K and 15K models, is designed for parallel operation, allowing multiple units to be connected for increased power output. This capability is beneficial for whole-home backup and off-grid applications where higher power levels are required. The maximum number of units that can be connected in parallel is limited by the inverter’s design and capacity.
Connecting Multiple Sol-Ark Units
To connect multiple Sol-Ark units in parallel, it’s essential to use a common DC bus and identical inverters. The DC bus should be designed to handle the maximum DC current of the system, and the inverters should be synchronized using the built-in parallel operation feature. When connecting multiple units, ensure that the AC output of each inverter is connected to a common AC bus, and the DC output is connected to a common DC bus. The maximum number of units that can be connected in parallel is 8 for the 12K model and 6 for the 15K model.
Configuration and Synchronization
To configure and synchronize multiple Sol-Ark units in parallel, follow the manufacturer’s guidelines and use the built-in parallel operation feature. This typically involves setting the inverter’s mode to “Parallel” and synchronizing the units using a common clock signal. The units should be connected in a star configuration, with the DC output of each inverter connected to a common DC bus, and the AC output connected to a common AC bus. This will allow the units to operate in parallel, providing a higher total power output.
