Don't know correctly about inverter series...
But Gree always take more amperes in normal Non-inverter AC. We have a Haier 1ton AC at our home and also a Gree Non-inverter 1ton AC at home..
Haier always operates at 4.5-5.5 amperes in normal operation whereas Gree operates at 6-6.8 amperes both the unit's are at ground floor and both room's have almost same conditions...
I haven't found any thing good in Gree AC'S in my point of view Gree just has good air flow.... Haier cool's better than Gree...
