700W Pwm Mppt Solar Inverter

HSI-70112P20 Low Frequency Pure Sine Wave Inverter with PWM Solar Controller and AC Charger

The conversion efficiency of an inverter is a key indicator of its performance. It indicates how much electrical energy is effectively used in converting direct current (DC) to alternating current (AC). It is usually expressed as a percentage. The conversion efficiency of a high efficiency inverter is typically between **95%-98%**, but this value can vary depending on a number of factors.

Main factors affecting the conversion efficiency：
1.Load rate
Conversion efficiency varies with load and is typically most efficient in the 50%-75% load range. At low loads, the efficiency decreases due to the increased proportion of static losses; at overload operation, the losses of the circuit components increase, which also reduces the efficiency.

2.Waveform type

• Pure sine wave inverter: High output quality, suitable for sensitive equipment, but the power conversion process is more complex and the efficiency is slightly lower.
• Modified sine wave inverter: simple structure, high conversion efficiency, but the output waveform may be unfriendly to some devices.

3. Internal structure and components: The use of high-efficiency components (such as low-loss MOSFETs) and optimised control circuits can significantly improve the conversion efficiency. In addition, advanced technologies such as Maximum Power Point Tracking (MPPT) can dynamically adjust the input power to achieve higher conversion efficiency.

Methods for improving conversion efficiency

• Appropriate load planning: Avoid prolonged low load or overload operation.
• Buy quality equipment: Choose an inverter with a high efficiency design.
• Combine with actual needs: Select the appropriate waveform type according to the nature of the load.
