Huawei SUN2000-4KTL-L1 Hybrid Inverter
4 kW rated AC output
Recommended for PV arrays up to 6 kWp
Two independent MPP trackers
Compatible with Huawei LUNA2000 batteries
Integrated Wi-Fi and FusionSolar monitoring
Maximum efficiency of 98.4%
Efficient Solar-Energy Conversion
The Huawei SUN2000-4KTL-L1 converts the direct current generated by solar panels into usable single-phase alternating current. Its two MPP trackers allow two independent panel strings to operate efficiently, even when they have different orientations or are exposed to different levels of sunlight.
The inverter supports a maximum DC input voltage of 600 V and operates across an MPPT voltage range of 90 to 560 V. With a maximum efficiency of 98.4% and a European weighted efficiency of 97.5%, it provides reliable and efficient energy conversion.
Battery-Ready Hybrid Operation
A dedicated high-voltage battery connection allows the inverter to be combined with compatible Huawei LUNA2000 battery-storage systems. It supports up to 5 kW of battery charging power and up to 4.4 kW of discharge power.
This enables surplus solar energy to be stored during the day and used later in the evening or whenever household demand exceeds current solar production. Backup power can also be provided when the inverter is combined with the required compatible Huawei backup equipment.
Smart Monitoring and Safety
Integrated Wi-Fi connects the inverter to the Huawei FusionSolar app, allowing users to monitor solar generation, household consumption, battery status and system performance. Optional accessories provide Ethernet or mobile-network connectivity.
The inverter includes arc-fault protection, anti-islanding protection, residual-current monitoring, surge protection and protection against overheating, overvoltage and short circuits.
Compact and Durable Design
The passively cooled inverter operates silently without a fan. Its IP65-rated enclosure is dust-tight and protected against water jets, allowing flexible installation indoors or outdoors. The unit weighs approximately 12 kg and measures 365 × 375 × 156 mm.
Conclusion
The Huawei SUN2000-4KTL-L1 is an efficient and flexible hybrid inverter for residential photovoltaic systems. Its battery compatibility, dual MPP trackers, comprehensive safety functions and intelligent monitoring make it a future-ready solution for increasing solar self-consumption and reducing dependence on the electricity grid.
