20kW Pure Sine Wave Off Grid Solar Inverter

Black Oxide Heat Sink

Uses a thickened aluminum heat sink to improve radiation rate 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 20kW off-grid 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 safety and durability. It helps maintain optimal operating temperatures, ensuring the grid-off 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 power 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.

What is the difference between on grid and off-grid inverter?

An on-grid inverter, also known as a grid-tied inverter, is designed to work in conjunction with the electrical grid. It converts DC (direct current) power generated by sources like solar panels into AC (alternating current) power, which can be fed back into the electrical grid or used to power appliances. These inverters synchronize the frequency and phase of the AC power with the grid's power to ensure smooth integration. On-grid inverters do not require a battery backup and rely on the grid for stable power. They also allow excess energy to be sold back to the grid, offering potential financial benefits to the user.

An off-grid inverter, also known as a stand-alone inverter, operates independently from the electrical grid. It converts DC power from renewable sources or batteries into AC power to supply power directly to appliances or a local electrical network. Off-grid inverters are typically used in remote areas where grid access is limited or unavailable. They often work in conjunction with battery storage systems to provide continuous power, even when renewable energy sources are not producing power (e.g., at night for solar systems). Unlike on-grid inverters, off-grid systems require careful design and management to ensure reliable power and proper battery maintenance.
