    5.7 SYSTEM WORK MODE Operating mode: SELLING FIRST: The inverter feeds all excess energy produced by the solar panels into the grid. If the "TIME OF USE" option is activated, battery energy can also be fed into and sold to the grid. The energy from the photovoltaic modules will be used to power the load and charge the battery, and only excess energy will be fed into the grid.
  • Page 35 SOLAR SELL: This option, which can be set either to ZERO EXPORT TO LOAD or ZERO EXPORT TO CT, allows any excess energy produced by the photovoltaic system to be fed into the grid. If it is not selected, the two programs indicated by default do not provide for such feeding into the grid.
