Technical Field

[0001] The present application relates to the technical field of inverters, and in particular to a photovoltaic-storage hybrid inverter that is easy to maintain. Background Art

[0002] A photovoltaic-storage hybrid inverter is an inverter that combines a solar photovoltaic power generation system and an energy storage system. It can convert solar energy collected by solar photovoltaic panels into electrical energy and store it in an energy storage device. This inverter also has the function of managing the flow of electricity as needed, and can achieve flexible switching between photovoltaic power generation, energy storage and grid connection to meet power needs in different scenarios.

[0003] Existing inverters are generally provided with a cover plate for protection, and the cover plate is generally fixed to the inverter box by multiple nuts. Due to the long-term use of the inverter, the internal components of the inverter may age or be damaged, so regular inspection and maintenance are required. However, since the cover plate is fixed to the inverter by nuts, when removing the protective cover, the nuts must be removed first, and then the inverter can be maintained. After the maintenance is completed, the cover plate must be tightened with screws. The entire maintenance process is too complicated and cumbersome, and a lot of time is spent on loosening and tightening the screws, resulting in low maintenance efficiency.

[0004] Therefore, there is an urgent need for a household storage all-in-one connection structure that has an appearance that matches the battery cabinet and is easy to install; and has a reasonable layout of input and output terminals and connecting wires to solve the above problems.
