And the development strategy and policy of zero energy consumption and no pollution in China are responded and realized.
Three power supply modes of the plateau type heat-preservation and water-purification integrated equipment are as follows:
1) mains supply priority mode
When the mains supply is normal (accords with the input voltage range of the machine mains supply), the mains supply charges the storage battery (if a solar controller (PV) is arranged in the machine mains supply, the mains supply and the PV charge the storage battery at the same time); on the other hand, the commercial power outputs stable alternating current for load use (the load does not consume PV and storage battery energy) after voltage stabilization;
when the commercial power is abnormal (the commercial power exceeds the working range of a machine or the commercial power is interrupted), the commercial power is converted into battery inversion power supply, and the storage battery supplies power to the load (if a solar controller is arranged in the solar energy inverter, when the PV generating power is greater than the load power, the PV supplies power to the load completely, redundant energy charges the storage battery, and when the PV generating power is less than the load power, the insufficient part is supplemented by the storage battery, and the PV and the storage battery supply power to the load together).
2) Solar (battery) priority mode
When the storage battery is fully charged (namely the voltage of a conventional single battery is 13.2 VDC), even if the mains supply input is normal, the machine is converted into battery inversion power supply, and the storage battery supplies power to the load (if a solar controller is arranged in the machine, when the PV generating power is greater than the load power, the PV supplies power to the load completely, and redundant energy charges the storage battery;
when the storage battery is in low voltage (namely when the voltage of a conventional single battery is 11 VDC), and the mains supply is normally input, the machine is switched to the mains supply mode to supply power, the mains supply supplies power to the load after voltage stabilization, and the mains supply charges the storage battery (if the solar controller is arranged in the machine, the PV and the mains supply charge the storage battery at the same time, and the load does not consume PV and storage battery energy).
Remarking: under the mains supply priority solar priority mode, when the charging current of the mains supply is not set to be 0A, the mains supply can charge the storage battery;
when the commercial power charging current is set to be 0A, the commercial power does not charge the storage battery, and only the solar thorn control device charges the storage battery.
3) Energy saving mode
The machine works in a battery inversion mode (invalid in a mains supply mode), when the load is lower than 10% of the rated load, the machine inverter can be started and stopped at regular time, and the effect of saving battery energy is achieved (namely the machine can intermittently interrupt inversion output); when the load is greater than 10% of the rated load, the machine inverter can always work in an inversion state (namely, the machine does not intermittently interrupt inversion output).
