The SolaX X3 Series inverter is a sophisticated PV inverter designed to convert the DC current from a PV generator into AC current for feeding into the public grid. It is a high-performance device that incorporates state-of-the-art technology, offering high reliability and convenient control features for optimal operation of your solar power system.
The primary function of the X3 Series inverter is to facilitate the conversion of solar energy into usable electricity for the grid. It is designed for outdoor installation with an IP65 protection level, ensuring its durability and resistance to environmental factors. The inverter features advanced DSP control technology and utilizes the latest high-efficiency power components to maximize energy conversion.
A key aspect of its functionality is the Optimal MPPT (Maximum Power Point Tracking) technology, which includes two independent MPP trackers. This allows the inverter to efficiently extract power from the PV array across a wide MPPT input range, even under varying sunlight conditions. The X3 Series also boasts advanced anti-islanding solutions, such as Active Frequency Drift (AFD), to prevent the dangerous islanding effect where the PV system continues to supply power to the grid after a voltage loss.
The inverter is equipped with various communication interfaces, including WiFi/LAN/GPRS (optional), RF (radio frequency), RS485/Meter, DRM, and USB. These interfaces enable comprehensive monitoring of the system's status, performance, output voltage, current, frequency, and fault information. This data can be delivered to a PC or other monitoring equipment, allowing users and installers to keep track of the system's operation.
For enhanced control and energy management, the RF control function (optional) allows the inverter to intelligently switch or operate designated loads. By connecting an external Smart Plug, the system can prioritize consuming surplus PV energy, thereby minimizing energy costs. The export control function further allows the inverter to manage the amount of energy exported to the grid, based on user preferences and local regulations, with higher accuracy when a meter is installed.
The X3 Series inverter also incorporates robust safety and protection features. It includes over/under voltage protection, DC isolation protection, monitoring for ground faults, grid protection, DC injection monitoring, backfeed current monitoring, residual current detection, anti-islanding protection, overload protection, and overheat protection. These features ensure the safe and reliable operation of the inverter and the entire PV system.
The X3 Series inverter is designed for ease of use and installation. It comes with a clear LCD screen that displays real-time information about the inverter's status, including power output, grid power, and daily energy generation. The LCD also serves as a human-machine interaction interface, allowing users to navigate through menus and adjust settings using press keys.
The control panel features LED status indications: blue for normal operation, yellow for communication, and red for faults. This provides a quick visual cue of the inverter's operational state. The menu interface allows users to access various settings and information, such as safety standards, date and time, password management, export control, DRM function, line impedance, and grid services. While end-users have limited authority to change settings, qualified electricians can perform professional configurations using an installer password.
The inverter supports system updates via a USB interface, allowing for future enhancements and bug fixes. The upgrade process is straightforward, involving inserting a U-disk with the update file into the USB port and following the on-screen prompts.
The X3 Series inverter is designed for minimal maintenance. However, routine checks are recommended to ensure optimal performance and longevity. The manual emphasizes that only trained and authorized professional personnel should perform servicing and maintenance work.
Periodic maintenance includes checking the cooling fins on the rear of the inverter for dirt accumulation. If covered, the fins should be cleaned with a soft dry cloth or brush to prevent overheating, which can lead to power loss. These checks should be performed regularly, especially if the inverter frequently loses power due to overheating.
Additionally, it is recommended to periodically check the inverter's indicators, keys, and display for normal operation. The input and output wires should also be inspected for any damage or aging. These checks should be performed at least every six months. The PV panels connected to the inverter should also be cleaned and their security checked at least every six months.
Safety checks are crucial and should be performed at least every 12 months by a qualified person. These checks involve verifying the proper functioning of the device and ensuring compliance with safety instructions and EC Directives. Any data from these checks should be recorded in an equipment log, and if the device malfunctions or fails any test, it must be repaired.
In case of troubleshooting, the manual provides a comprehensive list of faults and their corresponding diagnoses and solutions, such as checking connections, resetting the system, or contacting customer service. This allows for efficient identification and resolution of common problems.
For decommissioning, the manual outlines steps for safely disconnecting the inverter from DC input, AC output, communication, and optional wirings, followed by removal from its bracket. For storage and transportation, the inverter should be packed in its original packaging or an equivalent carton, stored in a dry place within a specified temperature range, and handled carefully. Disposal of the inverter and related components must adhere to local waste handling regulations, ensuring proper recycling.
