Q: How the electricity generated by PV can be used to give priority to the user's load, instead of the PV power being sent to the grid, and the load is taken from the grid? A: From the circuit principle, the current flows from the place where the voltage is high to the place where the voltage is low.
Usually solar inverters have three working modes, PV (battery) priority, mains priority and ECO mode. Which working mode can maximize the utilization of photovoltaic energy and meet customer requirements as much as possible. It certainly seems an appropriate subject of discuss.
The solar inverter load preferentially uses the energy provided by the photovoltaic. When the photovoltaic power generation rate is less than the load, the insufficient part is supplemented by the battery, and the photovoltaic and the battery share the load to supply power. Application area: This mode is used in areas with no or less electricity.
The disadvantage is that photovoltaic energy wastes a lot, and it may not be used in many cases. ECO (Energy saving) mode The solar inverter works in battery mode, and the load capacity is lower than 10% of the rated power of the inverter, the inverter will start and stop regularly to achieve energy saving effect.
ECO (Energy saving) mode The solar inverter works in battery mode, and the load capacity is lower than 10% of the rated power of the inverter, the inverter will start and stop regularly to achieve energy saving effect. When the frequency load is greater than 10% of the rated power of the inverter, the inverter will exit the energy-saving mode.
Application area: This mode is used in areas with no or less electricity. Mains electricity is expensive and frequent power outages. It is important to note that the inverter will switch to utility power when it needs to use the battery to a lower value. The advantage of this mode is that the solar energy can be fully utilized.
