Specifications
Product Description
The Huawei 3.68kW SUN2000L 3.68KTL-L1 Single-Phase Hybrid Inverter integrates a grid-tied inverter and high-voltage battery charger in a single compact unit. Designed for demanding residential self-consumption, it combines dual wide-range MPPT, active protections, and smart connectivity to achieve more usable energy and safety, with backup option in case of grid outages.
Main Features
- Peak efficiency of 98.4% (EU ~97.5%) to extract the maximum annual performance from your panels.
- 2 independent MPPTs with a tracking range of 90–560 V and a maximum input voltage of 600 V.
- 12.5 A per MPPT (Isc 18 A), compatible with high-current modules and unbalanced strings.
- HV Hybrid compatible with Huawei LUNA2000 batteries (5–30 kWh) and LG RESU 7H_R/10H_R.
- Automatic backup of essential loads via Backup Box-B0.
- Advanced safety: AFCI, type II SPD on DC/AC, anti-islanding and RCMU; IP65 enclosure.
Advantages or Benefits
- Savings and control: real-time monitoring with the FusionSolar app and optimization of self-consumption.
- Service continuity during grid failures by switching to battery in milliseconds.
- Quick installation: lightweight chassis (12 kg), mounting template, and integrated WLAN.
- Scalability: allows starting without a battery and expanding later without changing the inverter.
Purpose or Applications
Ideal for single-phase homes with medium consumption, roofs with multiple orientations or partial shading, and projects that prioritize efficiency, safety, and the possibility of energy storage.
