Operating modes Hybrid Solar Inverters As seen in Section 6.3, the inverter can operate in various operational logics, suiting individual needs. ATTENTION! Symbols depict “Power consumption” priority. 6.6.1 Self-use mode This mode stores excess PV power into the battery. If the battery is charged, or there is no battery, the excess PV power will be exported back to the grid/utility company.
Hybrid Solar Inverters 6.2 Grid trading mode priority 6.6.3 Off-grid mode Off-grid mode must only be used by systems that are not electrically connected to the grid at all. This mode is almost like Self-Use Mode, but the PV power will be curtailed if the battery is sufficiently charged, and the domestic load demand is lower than the amount of available PV power.
Hybrid Solar Inverters Reserve or Backup mode 6.6.4 The reserve or backup mode may be opened in the Self-Use or Grid-Trading Mode. This mode ensures that the battery is not drained past the Reserve SoC mark. The battery will cycle between 100% and the Reserve SOC.
CAUTION! Never use any solvents, abrasives, or corrosive materials to clean the inverter. The XLH series inverters require general maintenance to be performed once per year. Impurities such as dust and dirt accumulation on the heat sink may negatively affect the inverter’s ability to dissipate heat.
