Aiswei ASW_4K-LT-G2_PRO_AFCI Grid-Tied Inverter (4 kW, 3-Phase)

The Aiswei ASW_4K-LT-G2_PRO_AFCI 3-phase grid-tied inverter offers 4 kW of power and features two MPPTs with a maximum input current of 16 A. The device comes factory-equipped with a DC switch, arc fault circuit interrupter (AFCI), and a Type II DC surge protection device (SPD).

The Aiswei ASW_4K-LT-G2_PRO_AFCI 3-phase grid-tied inverter is a 4 kW device designed for photovoltaic installations. The LT-G2 Pro series features an increased input current of up to 16 A for each of its two MPPTs, making it compatible with higher-power solar modules. Standard communication with the monitoring system is established via Wi-Fi and RS485, with an optional 4G module available. Built-in shadow management features and integrated AFCI protection ensure the safety and optimal performance of the entire system.

Key features

• Increased DC input current (16 A) tailored for the new generation of PV modules.
• Built-in arc fault circuit interrupter (AFCI) and Type II DC surge protection device.
• Shadow Management function optimizing system performance under shaded conditions.
• Wide MPPT voltage range from 150 V to 1000 V.
• Equipped with Phoenix Contact DC connectors, requiring no crimping tools.
