It will switch to mains power mode for power supply,

1 ) Mains Power Priority Mode ( dl)

● When the mains power is normal (meeting Solar Energy Inverter-Controller Integrated Unit Mains input voltage range)—on one hand, the mains power charges the battery (if a built-in solar controller is present, both the mains power and PV At the same time, it charges the storage battery; meanwhile, the mains power is stabilized via a voltage regulator and then delivered as steady AC power to the load (which does not consume any energy). PV And storage batteries Energy);

● When the utility power is abnormal (utility power exceeds Solar Energy Inverter-Controller Integrated Unit (In case of a power outage or when the mains power is interrupted), the machine will switch to battery-based inverter power, with the storage batteries supplying power to the load. Electricity (if a built-in solar controller is present, when PV The power generated exceeds the load demand, entirely by PV Power is supplied to the load for use, with any excess energy sent to the battery. Charging; when PV The power generated is less than the load demand, with the shortfall compensated by the storage battery. PV Supplied to the load along with the storage battery.

2 ) Solar (Battery) Priority Mode ( d3)

● When the battery is fully charged—meaning the standard voltage of a single cell is 13.2VDC Time) , even if the mains power input is normal, Solar Energy Inverter-Controller Integrated Unit The system switches to battery-inverter power supply, with the storage battery providing electricity to the load (if a built-in solar controller is present, when PV The power generated exceeds the power consumed by the load. , entirely by PV Powering the load for use, with excess remaining Energy charges the storage battery. ; When PV The power generated is less than the load demand, with the shortfall compensated by the storage battery. PV Supplied to the load together with the storage battery. ;

● When the battery is low voltage—specifically, when the standard single-cell battery voltage is 11VDC at that time), and the mains power input is normal, at this moment Solar Energy Inverter-Controller Integrated Unit It will switch to mains power mode for供电, Power is supplied to the load after being stabilized by the utility grid, while the grid simultaneously charges the battery (if a built-in solar controller is present at this time). PV Simultaneously charging with mains power Battery is charging, but the load isn't consuming power. PV And battery capabilities Quantity) .

Note: In mains power priority /In solar-first mode, when the utility power charging current is set to not 0A At that time, grid power can charge the battery; when the grid charging current is set to 0A At that time, the utility power does not charge the battery—only the solar controller provides the charging.

3. Energy-saving mode ( d2)

● Solar Energy Inverter-Controller Integrated Unit Operation is in battery inverter mode (not effective in utility power mode). , when the load is below the rated load 10%, The machine inverter periodically starts and stops, helping to conserve battery energy (meaning the inverter output is intermittently interrupted). When the load exceeds the rated capacity, 10%, Machine The device will continuously operate in inverter mode (meaning the machine will not intermittently stop its inverter output).
