40kW Pure Sine Wave Off Grid Solar Inverter

Black Oxide Heat Sink

Uses 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 40kW inverter grid off. 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 safety and durability. It helps maintain optimal operating temperatures, ensuring the grid-off PV 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 pure sine wave inverter, 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 the MPPT wide voltage input function, maximize the use of solar power.

Tips: Differences between grid-tie inverter and off-grid inverter?

As the conversion device of the photovoltaic power station, photovoltaic inverters can be divided into PV grid-connected inverters and PV off-grid inverters according to their purposes. So how can we distinguish between these two types of photovoltaic inverters?

1. The purpose of the photovoltaic power generation system can be divided into independent (off-grid type) and grid-connected types. The inverter suitable for an off-grid power generation system is off-grid inverter, and the inverter suitable for a grid-connected power generation system is the grid-tie inverter.
   
   
2. Second, according to the waveform modulation mode of the inverter itself can be divided into square wave inverter, ladder wave inverter, sinusoidal wave inverter and combined-type three-phase inverter, which is the inverter manufacturers produced by the inverter itself to divide the waveform.
   
   
3. Third, according to the grid-connected system of photovoltaic power generation, it can be divided into transformer inverter and transformer-free inverter. This is mainly a classification of photovoltaic inverters from different requirements of grid-connected systems.
