residential solar inverter
Upgrade your home energy setup with our next-generation residential solar inverter series (1kW to 5kW), engineered to maximize energy conversion and long-term reliability for residential rooftop PV systems. Designed to handle the latest high-power photovoltaic modules, this single-phase on-grid solution combines compact aesthetics, superior safety features, and intelligent grid management to deliver exceptional ROI for installers, EPC contractors, and distributors.
Key Features & Advantages
High-Current Compatibility (20A Input) Featuring a single MPPT route with up to 20A string current, this inverter seamlessly pairs with modern, high-efficiency 210mm solar modules, maximizing power generation without current bottlenecks.
Maximum Solar Yield Gain more daily generation hours with an ultra-low 50V start-up voltage and a broad MPPT operating range (50V–550V). With 1.5x DC oversizing capability, your system captures maximum solar energy even during low-light morning and evening hours.
Advanced Safety & Protection Protect residential installations with built-in optional DC Arc Fault Circuit Interrupter (AFCI) technology. The system accurately detects and rapidly isolates arc faults to prevent fire hazards, alongside DC reverse polarity, anti-islanding, and short-circuit protections.
IP66 Outdoor Durability & Ultra-Lightweight Built for challenging environments, the IP66-rated enclosure supports flexible outdoor installation across temperatures ranging from -30°C to +60°C. Weighing just 6kg with a compact design, it enables single-person installation, significantly cutting labor and freight costs.
Smart O&M and Remote Diagnostics Equipped with Smart I-V Curve Diagnosis for precise string-level fault location. Integrated fault wave recording captures real-time AC voltage and current waveforms , while optional RS485, WiFi, and 4G modules allow seamless mobile app and web-based monitoring.

FAQ
Q: What is the maximum DC oversizing ratio supported by this series?
A: This series supports up to 1.5x DC oversizing. For instance, you can connect up to 7.5kW of PV array capacity to the 5kW model, optimizing morning and late-afternoon power yield.
Q: How does the ultra-low 50V start-up voltage benefit system performance?
A: The 50V start-up voltage allows the inverter to start generating electricity earlier at dawn and continue operating later into dusk, extending the daily power generation window compared to standard market alternatives.
Q: Can this inverter be installed outdoors in harsh weather conditions?
A: Yes. It comes with an IP66 ingress protection rating, protecting internal components against heavy rain and dust infiltration. It operates reliably within a temperature range of -30°C to +60°C.
Q: What remote monitoring options are available for installers and end-users?
A: The inverter supports RS485 as standard, with optional plug-and-play WiFi or 4G communication modules. Plant performance can be tracked in real time via our mobile App or web platform.
Q: What is the night-time self-consumption rate of the inverter?
A: The inverter consumes less than 1W during night-time standby mode, ensuring minimal parasitic power draw from the grid when there is no solar irradiance.
