50kW Pure Sine Wave Off Grid Solar Inverter

Black Oxide Heat Sink

Uses a thickened aluminum heat sink 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 50kW off-grid solar 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 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. And 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.

Why PV solar inverters must be placed in an air-circulated space?

For every 10 °C increase in ambient temperature, the life of the electronic device is halved. For the long-term exposure of this type of PV solar inverter to the hot sun, the internal temperature of the inverter will increase greatly, seriously affecting the life of the key components of the inverter. In order to protect the internal components, the inverter will derate the operation. Even if the temperature is too high, the solar inverter temperature will be faulty. It is recommended to add a sunshade to the PV inverter to avoid sun exposure.

When installed outdoors, the PV solar inverter should be equipped with a rain-proof sun protection awning to avoid direct sunlight and rain. Do not expose the inverter directly to the sun or other heat sources. Leave enough space for it to be installed and moved to the inverter. A minimum of 50cm of space is required around the inverter that enters and exits the wind. The solar inverter that enters and exits the wind from the left and right is the air entering from the side, and the space distance of more than 100cm is left on both sides. The PV solar inverter must be placed in a space where the air is circulated. The cooling method of a power inverter is divided into forced air cooling and natural heat dissipation. The power inverter itself is a heat source. All the heat should be emitted in time and cannot be placed in a closed space, otherwise, the temperature will rise higher and higher.
