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. Efficiency of Inverter per Output Power (Reference: inverter.com)
As a result, if you’re utilizing 20 watts of AC power, the inverter will be pulling 40 watts from the batteries, resulting in a 50 percent efficiency. A modest 200W inverter, on the other hand, may only use 25 watts from the battery to produce a 20-watt AC output, resulting in an 80 percent efficiency.
Below 10-15% of power output, efficiency is quite low. At high output power, the efficiency is steadily high with some small variations. The behavior in Figure 11.8 partially results from the fact that stand-by losses for an inverter are the same for all output power levels, so the efficiency at lower outputs is affected more.
It’s important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
In general, the standby power consumption of most inverters is relatively low, typically less than 1% of their rated power output. For a 1000W inverter, the average idle power consumption could be around 10-20 watts, while for a 2000W inverter, it could be around 20-40 watts.
Suppose the efficiency of the inverter is 90 percent, then 10 percent of the power is lost in the inverter. It depends on the load as to how efficient the inverter will be. Generally speaking, it is usually at its peak at about two-thirds of the capacity of the inverter.
