80kW Pure Sine Wave Off Grid Solar Inverter

Black Oxide Heat Sink

Used a thickened aluminum heat sink to improve the radiation rate; the cooling surface is stable and not easy to oxidize, black coating does not interfere with electrical conductivity. This results in better cooling and a longer lifespan for the 80kW off-grid power inverter. The black finish can improve the overall appearance of the inverter and make it blend more seamlessly with other components.

Powerful Cooling System

A powerful cooling system enhances the safety and durability. It helps maintain optimal operating temperatures, ensuring the grid-off pure sine wave inverter runs efficiently and effectively. This cooling system prevents overheating, which can lead to equipment damage and failure. Additionally, a well-cooled inverter can handle higher loads without risking performance degradation.

Anti-dust Protection

Reasonable cabinet design with a dust-proof net to reduce dust, prevent accidental touch, and improve safety performance. Anti-dust features enhance the reliability of the inverter off-grid, minimizing downtime and maintenance needs. This protection maintains efficiency by keeping internal components clean and functioning optimally, ensuring stable power conversion.

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, save more cost, and with MPPT wide voltage input function, maximum use of solar power.

What are the cooling methods of a power inverter?

At present, there are two main ways of cooling the inverter: One is natural cooling, and the other is forced air cooling.

1. Natural cooling. Natural cooling means that the local heating device is cooled to the surrounding environment to achieve temperature control without using any external auxiliary energy. This usually includes three main heat transfer modes: Heat conduction, convection, and radiation. Natural heat dissipation or cooling is often applied to low-power devices and components that do not require high-temperature control, low heat flux density for device heating, and were sealed or densely assembled devices are not (or are not required to) use other cooling techniques. At present, mainstream single-phase inverters on the market and three-phase inverters below 20 kW off grid solar inverter, most manufacturers adopt natural cooling.
2. Forced air cooling. Forced air cooling is mainly a method of forcing the heat emitted by the device by means of a fan or the like to force the air around the device to flow. This method is a heat dissipation method that is easy to operate and has obvious effects. This cooling method can be used as much as possible if the space between the components within the component is suitable for air flow or for the installation of a local heat sink. The method of improving the forced convection heat transfer capability increases the heat dissipation area and generates a relatively large forced convection heat transfer coefficient on the heat dissipation surface. Increasing the heat dissipation area of ​​the surface of the heat sink to enhance the heat dissipation of electronic components has been widely used in practical engineering.
