As shown in Fig. 4,5,7, PWM2 signals, two groups（The charging first via, the second tunnel of charging）Be it is common, it control
Metal-oxide-semiconductor circuit（Q3/Q6, Q11/Q12）Equivalent to total lock of charging, if it close if, no matter PWM1 what, all can not
Charging.
Q2/Q5 and Q9/Q10 working condition is on the contrary, because be two signals control by opposite in phase.
PWM1 is exactly main control signal, but because being that battery is divided into two groups, is charged respectively under a pwm signal,
So there is control signal all the way to need " triode negates ".
The electricity that solar panel is sent is sent to national grid by combining inverter, because the power consumption at night is few,
National grid, which has, much abandons electricity, mostly from thermal power plant, wind energy, nuclear power station etc..So after ten one points of night, can pass through
Mobile phone app sends instructions to the utility model scheduling system（System is connected with the wifi of family in itself）, allow it to close K2, make
These electric energy that should be slatterned are stored into lithium battery by AC/DC DC voltage-stabilizings Switching Power Supply and charging and discharging lithium battery controller
In group.
When power consumption high period on daytime, such as 9 points -16 points, then sent instructions by mobile phone app to scheduling system, closed
Combination switch K1, lithium battery group is allowed to be powered also by combining inverter to national grid, due to before using the price and hair for abandoning electricity
The price of electricity has gap, so, user can therefrom benefit.For example, combining inverter capacity is 8000W, if lithium is electric
Pond can send the electricity of 4 hours, then be exactly 32 degree of electricity.Install that the family of this system is more, and income is more obvious, because can be with
It is uniformly controlled the charge and discharge for abandoning electricity.
If in peak of power consumption on daytime, family's also electricity consumption, then double power supply automatic transfer switch then keeps normal condition,
The electric energy issued using lithium battery group by ordinary inverter, when abandoning electric more at night, automatic change-over can redirect,
Standby zero line live wire is jumped to from conventional zero line live wire, seamless electric power switching is realized, supplies household electricity.
