4What’s the difference between a high-frequency inverter than a low-frequency inverter?

1. Well, essentially, from a physical standpoint, high frequency inverter are High efficiency, do not have big heavy copper transformer. So it is smaller and lighter than a low-frequency inverter.

2. Low frequency inverter is High surge capability and more stability, Long continuous draw. it contains a large copper transformer. it’s going to be bigger and heavier than high-frequency inverter.

3. High frequency inverter take up less room and it is of a big advantage in a lot of RVs, work trucks and small home appliances and office(lighting, TV, Fan and computers).

Low frequency inverter are suitable for larger and long continuous draw loads, such as motors under load, compressors and air conditioners.

5How to calculate the working time of Your Solar Products?
Working time=Battery capacity*Battery Voltage*DOD of Battery*Inverter efficiency/Loads power.
For example, 12V/100AH Battery to power a 100W Light,
Working time=100AH*12V*0.7*0.9/100=7.56Hours
*Battery DOD=70%
*Inverter efficiency=90%
