10kW Pure Sine Wave Off Grid Solar Inverter

LCD Display

It enhances user experience by offering straightforward control and configuration options, often through a user-friendly interface. It provides clear and easy-to-read information on the inverter's status, such as voltage and current. The display can show error codes and alerts, enabling timely troubleshooting and maintenance of 10kw off grid inverter. An LCD consumes minimal power.

High Speed Cooling Fan

The solar inverter generates heat during operation due to power conversion. The cooling fan improves cooling efficiency, which helps regulate the temperature and prevents overheating of off grid pv inverter. The high-speed fan ensures stable operation even in hot environments, reducing the risk of unexpected shutdowns. The fan can operate at varying speeds based on the inverter's load, making it energy efficient.

Multiple Protection Functions

Short-circuit protection quickly detects and isolates faults, preventing damage to the inverter and other connected devices. Over-voltage and under-voltage protection ensure that the grid-off inverter operates within safe voltage ranges, protecting the system from fluctuations. These protection functions enhance the safety, reliability, and longevity of off-grid inverters and the systems they support.

Features

• Two kinds of start modes: Step-down voltage start and variable frequency start. Customers can set the start mode according to the type of their load.
• The output voltage can be set between -40 % to +20 % of the rated voltage. The output voltage has an accuracy of ±1%.
• Pure sine wave output. With a good dynamic response of less than 50MS, the waveform distortion rate is lower, with higher conversion efficiency and stable output voltage.
• Adopts a black pure aluminum radiator, which ensures the best radiating performance.
• Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, power consumption (kWh), time and date, temperature, and fault code display.
• Wide input voltage can work without a battery and solar charge controller, saving costs, and the MPPT wide voltage input function maximizes solar power use.

What should we pay attention to when designing off grid inverter in photovoltaic system?

The photovoltaic off-grid system has no uniform specification and it must be designed according to the user demand. The model selection and calculation of components, inverters, controllers, batteries, cables, switches, and other equipment are mainly considered. Before the design, in order to do a good job in the preliminary work, it is required to understand the user's load type and power, the climatic condition of the installation site, and the electricity consumption of the user. After making clear the demand, the scheme can be well compiled.

• The voltage of the component and the voltage of the battery should be matched. The PWM controller solar module and the storage battery are connected by an electronic switch, without inductance equipment in the middle. The voltage of the component is between 1.2 and 2.0 times the voltage of the battery. If the battery has a voltage of 24V, the input voltage of the component is within 30-50V. The MPPT controller has a power switch tube and an inductor circuit in the middle. The voltage of the component is about1.2-3.5 times the voltage of the battery. If the battery has a voltage of 24V, the component input voltage is within 30-90V.
• The output power of the component must approach to that of the controller. For example, in the case of a 48V 30A controller with an output power of 1440VA, the power of the component should be around 1500W. In selecting the controller, please firstly check the voltage of the battery, and then divide the component power by the voltage of the battery, which is exactly the output current of the controller.
• If the power of one inverter is insufficient, multiple solar inverters must be connected in parallel. The output of the photovoltaic off-grid system is connected to the load. The voltage, current phase, and amplitude of each inverter output terminal are different. If the inverter is connected in parallel with the output terminal, it is required to add an inverter with the parallel operation function.
