Higher power inverters tend to have higher no load draw 4. Inverters do not have uniform efficiency across their whole power range (most but not all will be most efficient at or near their limit) 5. No inverter is more efficient than the most efficient inverter, so the more you can run directly from DC the less efficiency penalty you get hit with.
The inverter has an 87% efficiency rating. Now take a 4000 watt inverter like the Energizer 4000 which uses about 25 watts in standby mode. Plug the same 35 watt fan into it and the inverter consumes 55 watts. Use the same steps as above. The efficiency rating is only 63%. But if you increase the load, efficiency goes up.
Well, size does matter, but there is more to it. An inverter uses 10% more power than its appliance load due to inefficiency and standby mode requirements. Inverter efficiency increases with a higher load, so they should always run close to full capacity.
In general, if the inverter is loaded less than 15%, the efficiency will be low. As a result, a good match between inverter capacity and load capacity will allow us to obtain more efficiency, which is more ac output power from the inverter for the same DC input power.
Inverters play a crucial role in converting DC power to AC power, but choosing the right size is essential for optimal performance. In this article, we'll explore the potential implications of using an inverter that is too big for your power needs, shedding light on the effects and considerations associated with oversized inverters.
The highest efficiency point is never at full flat out power as mentioned above by previous posters. Its probably at about 15% to 20% of rated power which can fit in very well with normal domestic load profiles. Many inverter manufacturers lie a little bit and quote the max rated power, and efficiency at the highest efficiency point.
