A. We accept TT,30% deposit and 70% balance agaisnt copy of BL

Q 2. how's the delivery time ?

A. usually it will take about 25 days for production

Q 3. tell me the standard of package?

A. For the small capacity, it use carton, but for big capacity, we will use strong wooden case for protection.

Q 4. what kind of material of transformer?

A. we have two types, one 100% copper and the other is copper with aluminum.It depends on your requirment. In fact,those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price.

Q:Can a solar inverter be controlled remotely?: Yes, a solar inverter can be controlled remotely. With the help of advanced monitoring systems and communication technologies, users can remotely access and control their solar inverters. This allows for convenient monitoring of power generation, performance optimization, and troubleshooting from any location with internet connectivity.

Q:How does a solar inverter handle voltage harmonics?: A solar inverter handles voltage harmonics by using filtering techniques and advanced control algorithms. These methods help to smooth out the output voltage waveform, reducing or eliminating any unwanted harmonics.

Q:How does a solar inverter synchronize with the grid frequency?: A solar inverter synchronizes with the grid frequency by continuously monitoring the frequency of the electricity supplied by the grid. It adjusts its own output frequency to match the grid frequency, ensuring that the electricity it generates is synchronized with the grid. This synchronization allows the solar inverter to seamlessly inject power into the grid and maintain a stable and reliable electrical supply.

Q:How do you calculate the efficiency loss due to temperature for a solar inverter?: To calculate the efficiency loss due to temperature for a solar inverter, you need to consider the temperature coefficient of the inverter. The temperature coefficient represents the percentage decrease in efficiency for every degree Celsius increase in temperature. By multiplying the temperature coefficient with the temperature difference from the inverter's rated temperature, you can estimate the efficiency loss. For example, if the temperature coefficient is 0.5% per degree Celsius and the temperature increase is 10 degrees Celsius, the efficiency loss would be 5%.

Q:What is the role of a maximum power point tracker in a solar inverter?: The role of a maximum power point tracker (MPPT) in a solar inverter is to constantly monitor and adjust the output voltage and current from the solar panels to ensure they are operating at their maximum power point. By tracking and maintaining this optimal operating point, the MPPT increases the overall energy efficiency and power output of the solar system. This is particularly important as solar panel performance can be affected by various factors such as shading, temperature, and varying sunlight intensity.

Q:Can a solar inverter be used in standalone systems?: Yes, a solar inverter can be used in standalone systems. Standalone systems, also known as off-grid systems, are not connected to the electrical grid and rely on alternative energy sources like solar power. In these systems, a solar inverter is essential as it converts the direct current (DC) generated by the solar panels into alternating current (AC) that can be used to power appliances and equipment. Additionally, standalone systems often include batteries to store excess energy, and a solar inverter helps manage the charging and discharging of these batteries.

Q:How does a solar inverter protect against overvoltage or overcurrent?: A solar inverter protects against overvoltage or overcurrent by continuously monitoring the voltage and current levels of the solar panels. If it detects an excessive voltage or current, it automatically disconnects the panels from the grid to prevent any damage. Additionally, the inverter may also have built-in protective devices like surge suppressors or fuses to further safeguard against overvoltage or overcurrent situations.

Q:Can a solar inverter be installed indoors?: Yes, a solar inverter can be installed indoors.

Q:Can a solar inverter be connected to a smartphone app for monitoring?: Yes, a solar inverter can be connected to a smartphone app for monitoring. Many solar inverter manufacturers provide smartphone apps that allow users to monitor their solar energy production, track performance, and receive real-time updates on their system's performance. This integration enables users to conveniently monitor and manage their solar power system from their smartphones.

Q:Can a solar inverter convert DC power to AC power during a power outage?: No, a solar inverter cannot convert DC power to AC power during a power outage. During a power outage, the solar inverter relies on the grid to function, and without grid power, it cannot convert DC power from the solar panels into usable AC power.
