I ask my supplier about efficiency of my mono phase induction motor. he sent me that; Efficiency eff≥46% What ise the mean of that. 46% is very low. isn't it or is there anything i overlooked.

i have a 1500 W load and 500W PV panel. I use grid to supply my load by the aid of 400V output Partial switcing converter. I want to use my PV panels and not to pay for extra energy i have to design a grid cooperated system. i know that i need a MPPT which has a 400V output. I don't know how to design a boost type MPPT and how to connect it to LOAD input after the designing a MPPT. Assuming that; i designed a MPPT with 400V output , what must i do after. Directly connection it to load? If a regulation problem occurs at output of PFC or MPPT what will do? Is there any dc to dc connection methode? Could you please help me in killing my troubles. Thanks.
