  "textContent": "Provided are an inverter system and a control method for the inverter system, and relates to the field of inverter system technologies. The inverter system includes: a direct current-to-alternating current circuit, a phase relay being disposed at a phase line connected to the direct current-to-alternating current circuit; a first capacitor and a second capacitor that are connected in series between a positive bus and a negative bus of the inverter system; and a first switch module, the first switch module having a first terminal connected to inverter-side ground via a current-limiting resistor in an inverter nighttime repair circuit and a second terminal connected to a neutral point between the first capacitor and the second capacitor. The first switch module is configured to, switch, prior to the inverter system being connected to a power grid, to a first operating mode in which the first terminal is connected to the second terminal.",
