同一牌子新機計, 變頻同定頻
一年 相差 $1500 左右…..

Most brands are having inverter AC's but Gree offering a few models. This is marketing strategy to jack up the price, in fact, going back to era 70 when AC's were kind of extravagant items. Being fooled without noticing. But for commercial area with central plant of few hundred tons, inverter drive is a must for energy saving.
For example, selling point of R410a when compared to R22 was ozone depletion. The difference was only 6% quoted after discontinuation of R22 units

A fixed speed unit would still turn on and off to save energy but more noise and discomfort. Room acting as temperature buffer.
If both running at 50Hz continuously due to appliance sizing, the fixed speed one is more energy saving due to no inverter board loss.
