A photovoltaic inverter is the core power electronic device of a solar power system, acting as a critical hub connecting PV modules, energy storage batteries, electrical loads and the public power grid.

Solar panels generate direct current (DC), which cannot be directly used by household appliances or industrial equipment. The photovoltaic inverter converts DC into grid compliant sinusoidal alternating current (AC) for self consumption and surplus electricity feed in to the grid. It also integrates maximum power point tracking, multi layer safety protection, intelligent monitoring and O&M capabilities. Its performance directly determines power output, safety and service life of the PV station.

Core Product Advantages

✅ High efficiency Power Generation for Higher Returns Multiple independent MPPT channels with wide operating voltage range support early startup and late shutdown. DC over rating is available to match high power and bifacial PV modules. The maximum European efficiency reaches over 99%, fully tapping solar potential, cutting power loss and improving overall station revenue.

✅ Multi level Protection for Stable & Safe Operation IP65 / IP66 high ingress protection rating supports outdoor wall mount installation, adapting to harsh environments including high temperature, high humidity, salt spray and dust. Dual stage DC & AC lightning protection. Optional AFCI DC arc fault detection quickly identifies DC arcing risks to prevent fire hazards. Built in anti islanding, over voltage, over current, short circuit, earth leakage and reverse connection protections safeguard equipment and personal safety.

✅ Intelligent Monitoring for Easy Operation & Maintenance Multiple communication options: WiFi, 4G, Ethernet and RS485. Check real time power yield, operating status and fault alarms via mobile APP and cloud platform remotely. Intelligent IV curve diagnosis rapidly detects module shading, aging and string anomalies. Remote parameter configuration and firmware upgrade reduce on site service costs for full visibility of station conditions.

✅ Flexible Installation for Diverse Scenarios Modular design fits residential rooftops, factory rooftops, mountain site projects, agro PV complementary plants and ground mount power stations. User friendly wiring simplifies construction. Stable performance is maintained even with inconsistent module orientations and partial shading.

✅ Energy storage Compatibility (Hybrid Models) Hybrid PV storage inverters allow battery connection with automatic grid tied / off grid mode switching. Automatic charging discharging based on time of use electricity prices enables peak load shifting and emergency backup power during grid outages for higher energy self sufficiency.

Main Types of Photovoltaic Inverters

1. String Inverter (Market Mainstream)

Power range: 3250 kW Each PV string features independent MPPT. Failure of one unit only affects its corresponding string without full system shutdown. Strong resistance against partial shading. Applications: residential PV, factory rooftops, mountain site PV, agro PV & fishery PV distributed stations.

2. Central Inverter

Power range: 500 kW to megawatt level Multiple PV strings converge before centralized inversion. High single unit power output for sites with uniform solar irradiance. Applications: large scale desert ground mount PV power stations on flat terrain.

3. Microinverter

Power range: 200-1500 W. One microinverter serves one or 2-4 PV modules for module level independent optimization. Applications: balcony PV, BIPV, small rooftops with heavy shading. High safety level with relatively higher total system cost.

4. Hybrid PV storage Inverter (All in one Storage Inverter)

Bidirectional inversion supporting both PV panels and storage batteries. Dual grid tied / off grid modes. Applications: residential & commercial industrial projects requiring backup power, peak valley arbitrage or unstable grid conditions.

Key Functions

DC-AC Power Inversion: Convert DC solar power into standard 50 Hz sinusoidal AC that meets requirements for local loads and grid interconnection.

MPPT Maximum Power Point Tracking: Track real time changes in irradiance and temperature to keep PV modules operating at maximum output even under cloudy conditions.

Grid connection Protection: Anti-islanding, over/under voltage and over/under frequency protection for rapid disconnection during grid anomalies to secure grid maintenance personnel.

Intelligent Fault Diagnosis: IV-scan and string monitoring automatically detect hot spots, shading and module aging with fault alarms.

Data Collection & Cloud based O&M: Collect and store power generation statistics. Review daily and cumulative energy yield and perform remote debugging & upgrading.

PID Recovery (Optional): Night time potential induced degradation recovery restores PV module performance and extends service life.
