100kW 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 100kW 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 safety and durability. It helps maintain optimal operating temperatures, ensuring the grid-off power 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 off-grid PV 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 are the important points of solar inverter installation and maintenance?

1. Before installation, you should first check whether the solar inverter is damaged during transportation.
2. When selecting the installation site, it should be ensured that there is no interference from any other power electronic equipment in the surrounding area.
3. Before making electrical connections, be sure to cover the DC side circuit breakers with opaque materials. When exposed to sunlight, the PV array will generate dangerous voltages.
4. All installation operations must be performed by professional technicians only.
5. The cables used in the photovoltaic power generation system must be firmly connected, with good insulation and appropriate specifications.
6. All electrical installations must meet local and national electrical standards.
7. The inverter can be connected to the grid only after obtaining the permission of the local power department and all electrical connections are completed by professional technicians.
8. Before performing any maintenance work, first, disconnect the electrical connection between the inverter and the grid, and then disconnect the DC side electrical connection.
9. Wait at least 5 minutes until the internal components are discharged before performing maintenance work.
10. Any fault that affects the safety performance of the inverter must be eliminated immediately before the solar power inverter can be turned on again.
11. Observe the static protection regulations and wear an anti-static wrist strap.
12. Visually inspect the equipment for damage or other dangerous conditions before operation.
13. Pay attention to the hot surface of the solar inverter. For example, a heat sink of a power semiconductor or the like maintains a relatively high temperature for a period of time after the inverter is powered off.
