IP21 hybrid inverter
3.6KW/6.5KW Dual Power & US 120V Single Phase Compatibility
This IP21 Hybrid Inverter available in 3.6kW & 6.5kW is a compact single-phase solar inverter specially designed for 120V household grid standards. With IP21 indoor protection rating, it integrates solar power generation, grid connection and battery energy storage into one all-in-one unit. Ideal for small and medium residential solar systems, this 120V single-phase hybrid inverter delivers stable, efficient and reliable power solution for home energy self-consumption and emergency backup use.
Built to fit the unique electrical demands of US homes, the inverter delivers scalable power and seamless compatibility with 120V single-phase systems:
Power Range for Every Home: The 3.6KW model suits small to medium homes (1–3 bedrooms) with 2–4kW solar arrays, powering essential loads like LED lighting, laptops, refrigerators, and small kitchen appliances. The 6.5KW model caters to larger homes (3–5 bedrooms) or those with high-demand devices (EV chargers, window AC units, well pumps), pairing with 4–7kW solar arrays.
US Standard 120V Output: Directly delivers 120V AC (60Hz) to match 95% of US household devices-no transformers needed for standard appliances (e.g., toasters, TVs, microwaves) or critical loads (e.g., medical oxygen concentrators, Wi-Fi routers). Supports 100% load capacity for resistive, inductive, and capacitive loads.
Peak Surge Capacity: 2x instantaneous peak power (7.2KW for 3.6KW model, 13KW for 6.5KW model) for 5 seconds, ensuring smooth startup of high-wattage devices like air conditioners or power tools-eliminating tripping issues common with low-surge inverters.
Off-Grid Independence + Hybrid Flexibility
The inverter combines off-grid autonomy with multi-energy input flexibility, adapting to US rural and unreliable grid scenarios:
Pure Off-Grid Operation: Runs entirely on solar + battery power, ideal for rural US areas without grid access (e.g., mountain cabins, remote farms). Maintains stable 120V output even with fluctuating solar input, ensuring uninterrupted power for daily use.
Hybrid Backup Mode: For grid-tied areas with frequent outages (e.g., hurricane-prone Florida, wildfire-impacted California), it automatically switches to battery/solar power within 10ms of grid failure-providing seamless backup without downtime.
Multi-Energy Input: Supports solar PV (200–500V DC input, compatible with 60/72-cell US-standard panels), 48V/51.2V LiFePO4 batteries (common in US home storage), and optional generator input (for extended cloudy periods). Automatically prioritizes solar > battery > generator to minimize fuel use.
Intelligent Management for US Lifestyles
Equipped with user-friendly controls and monitoring tailored to American homeowners:
Load Prioritization: Lets users tag critical loads (e.g., medical devices, refrigerators) to receive power first during low-battery situations-critical for US households with health needs or food storage requirements.
Remote Monitoring: Wi-Fi/Bluetooth connectivity links to a mobile app (compatible with iOS/Android), displaying real-time solar production, battery state of charge (SoC), load usage, and system status. US users can monitor a vacation cabin's power remotely or receive low-battery alerts.
Auto-Battery Management: Prevents overcharge/over-discharge of LiFePO4 batteries, extending lifespan by 2–3 years. Customizable charging/discharging thresholds adapt to US seasonal sunlight changes (e.g., higher SoC targets in winter).
