| Zusammenfassung: | The invention discloses a tower-type solar off-grid and grid-connected inverter and an off-grid and grid-connected system, and relates to the technical field of tower-type inverters. The tower-type solar off-grid and grid-connected inverter can be applied to a tower-type solar off-grid and grid-connected system and an uninterruptible power supply. The tower-type solar off-grid and grid-connected inverter comprises a main control board, a bypass branch and a power branch, the bypass branch is connected with the power branch in parallel, the power branch comprises a rectifier and an inverter circuit, the rectifier is connected with commercial power and the inverter circuit, a battery connecting point used for connecting a battery is arranged between the rectifier and the inverter circuit, and when the commercial power is normal, the inverter circuit is connected with the main control board. The commercial power supplies power to the load through the bypass branch and supplies power to the battery through the re |
