Huawei SUN2000-4KTL-L1 Hybrid Inverter | 4000W | IP65 | 90–560Vdc | Single-Phase | 2 MPPT

The SUN2000-KTL-L1 series are single-phase hybrid inverters designed to maximize self-consumption in residential installations. They operate as grid-connected inverters while simultaneously managing energy storage through batteries, increasing energy independence and system flexibility.

They incorporate active safety technology with AI-powered Arc Fault Circuit Interruption (AFCI), enhancing overall system protection. Featuring two independent MPPTs, they provide greater flexibility in PV array design and can deliver up to 30% more energy when used with compatible optimizers. With an IP65 protection rating, they are suitable for outdoor installation.

They are compatible with Huawei Smart ESS battery systems from 5 kWh up to 30 kWh, allowing up to 5 kW battery charging power and up to 5 kW AC output power (depending on model). Backup power supply is available when used with the Backup Box, ensuring energy availability during grid outages.
