Two 60K-3P Inverters, One AES 210HV Battery Cabinet (120kW/209kWh)

Two Sol-Ark 60K-3P Inverters, One AES 210HV Battery Cabinet

Performance

Peak Discharge Rate (2 hours). A single AES 210HV cabinet can deliver a continuous current of 157 A, corresponding to approximately 104 kW of power output from the cabinet. In a configuration with two Sol-Ark 60K-3P inverters, the current is divided evenly so that about 80 A is used by each inverter. This setup adjusts each inverter’s maximum battery output to align with the cabinet’s current limitation and protects the system from overloading. The inverters maintain their full potential to deliver 60 kW of output each when supplemented by DC-coupled solar input, resulting in a combined maximum system output of 120 kW under optimal solar plus battery conditions.

Scalability

The Sol-Ark system-level scalability supports up to 10 paralleled inverters on the AC bus. A configuration with two Sol-Ark 60K 3P inverters per AES 210HV achieves a maximum power output of 600 kW and energy storage of up to 1.06 MWh across all 10 inverters.

Ten Paralleled Inverters

DC Wiring

Each inverter’s battery input terminals are connected to the AES 210HV using two pairs of 50 A conductors (two positive and two negative cables per inverter) for a total of four positive wires and four negative wires.

Communication

A dual inverter set up uses two LYNK II Gateway devices (950-0025)—one LYNK II that is included with the AES 210HV cabinet and a second purchased separately. Each LYNK II Gateway connects to the BMS1 port of its respective inverter and to the J3 or J4 port on the battery cabinet’s High Voltage Box.

In this configuration, each LYNK II device emulates the battery for its respective inverter. From the inverters’ perspective, they believe they are connected to separate batteries and the inverters naturally balance the load across each other for seamless operation.
