Embodiment Construction

[0013] In the accompanying drawings, integrated circuit IC1 and capacitor C3 provide 9-volt regulated power supply for the oscillation circuit and undervoltage switching circuit, pin 1 is the input pin connected to terminal 1 of KA3-2, and terminal 2 of KA3-2 is connected to the positive pole of battery 2 , Terminal 3 of KA3-2 is connected to the positive pole of battery 1. Pin 2 of IC1 is connected to pin 2 of KA1-2, and terminal 1 of KA1-2 is grounded. Pin 3 of IC1 outputs a stable voltage of 9 volts. The negative terminal of capacitor C3 is connected to pin 2 of IC1, and the positive terminal is connected to pin 3 of IC1. The 7 pins, 8 pins and 10 pins of the integrated circuit IC2 are connected to the 2 pins of IC1, and the 14 pins and 5 pins are connected to the 3 pins of IC1. Pin 2 is connected to one end of resistor R5, the other end of R5 is connected to one end of capacitor C1, and the other end of C1 is connected to pin 2 of IC1. Pin 6 is connected to the connecti...

Abstract

A photovoltaic preferential full automatic power utilization adjuster consists of time configuring and control circuit, charging circuit, inversion circuit, photovoltaic power supply circuit, under voltage switching locking circuit, and 220 volt ac power supply autonomous switchover circuit. In said invention, relay KA 3 contact on / off according to accumulator variation in voltage to realize automatically switching accumulator 1 to accumulator 2 or valley power supply; relay KA 2 contact on / off according to accumulator 2 variation in voltage to realize automatically switching accumulator to electric network power supply in power famine, relay KA1 contact on / off according to configuring time to realize automatically switching electric network power supply and accumulator 2 power supply after inversion to realize automatically charging using half price valley electricity. Said invention uses Relay KA 1, KA 2 and KA 3 combination, thus enabling users first use photovoltaic electricity, half price valley electricity in overcast and rainy day, and almost not using peak electricity of electric network.

Description

technical field [0001] The invention relates to a bidirectional power converter device and a photovoltaic power supply device. In particular, it is a fully automatic power regulator capable of fully automatic charging, inverter and undervoltage switching. It belongs to the application field of electronic technology. Background technique [0002] The current photovoltaic power supply can only automatically switch to grid power supply when the battery power supply is insufficient. It cannot distinguish the peak and valley power of the power grid. The current bidirectional power converter (charging, inverter) can convert the 220-volt alternating current into a low-voltage direct current for charging the storage battery, and can also convert the direct current of the storage battery into a 220-volt alternating current. However, it doesn't: Automatically trough charge at half the price overnight. In the daytime, the grid power supply is automatically cut off, and the battery ...
