At present, the following schemes are mainly used for the transportation of outdoor inverters on the market.

(1) Considering the waterproof requirement of the top of the outdoor inverter, no lifting piece is designed on the top, and only a forklift can be used for transferring;

(2) when satisfying fork truck and transporting, increase a cap at outdoor dc-to-ac converter top, hoist and mount piece is placed inside the cap, adopts bolted connection with the rack frame after the whole welding, can realize fork truck and transport and hoist and mount and transport.

The above two designs have the following problems.

(1) Considering the waterproof requirement of the top of the outdoor inverter, although the top has no hoisting beam or hoisting position, the transportation requirement of the forklift can be met, and the transportation requirement of the hoisting under various complex conditions in ports and project sites can not be met;

(2) although the requirement of hoisting the outdoor inverter can be met by adding the top cover on the top of the outdoor inverter, the added top cover needs to bear the weight of the whole inverter, so that the added top cover needs to have enough bearing capacity, the cost of the additionally added cap is higher than the cost, and the sealing between the top cover and the inverter frame needs to meet the requirement of waterproofing the top.
