High Frequency vs. Low Frequency Inverter
HBR, USA (6500'' in ENE AZ) Aug 10, 2022. #3. Most modern inverters are high frequency; however, high frequency (HF) is used in place of "transformerless" to the consumer. Low frequency (LF) has come to mean, "big fat transformer that weighs a shitload and has true 2-3X, 20-30 second surge capability". IMHO, you can''t count on a …
