Method.
Background technology
The existing industry and commerce roof power station overwhelming majority belongs to light weight steel structure, and potential installation scale will reach 100GW, but
Many units set up solar energy but can not the grid-connected or grid-connected electricity that sends out come, power grid can not but digest, due to national grid
Limitation either interconnection technology is insufficient or government decree is complicated, thus grid-connected power supply subsidy can not be taken, and when low-pressure side without
When method digestion produces excessive solar energy electricity, these excessive electricity are can not inversely to go to power grid high-pressure side, will become wave
Take.
Someone sets not grid-connected special equipment thus, and the solar energy sent out is used in not grid-connected dedicated direct current or friendship
Power equipment is flowed, but when solar powered insufficient, these equipment will switch back into general mains-supplied, either single switching is opened
It closes or solar energy can not be all fully utilized in multiple switching switches.When exceeding the wattage of special equipment when solar energy is abundant, meeting
There is very big a part of solar energy to be not used to equipment, become waste, it is special to set when solar energy deficiency special equipment wattage
Standby to be switched to alternating current, generated solar energy can not become auxiliary power at this time, can only solar energy caused by empty consumption, become more
Big waste.
Because of the above problem and shortcoming, 220Vac is converted the solar into using inverter simultaneously without using special equipment
Net, the model that electricity is sold in this direct online is simple and relatively reliable, and gradually becomes current solar energy power generating by favor
The mainstream of application.But low-pressure side is grid-connected, if user power utilization can not dissolve, can be sent to upper level power grid by the way that transformer is counter,
And distribution transformer design is not to be allowed for anti-power transmission can, it is necessary to need to install anti-backflow device to avoid the anti-of electric power
It send, as a result multiple electric power can only be consumed in low-pressure side void as described above.In addition Utilities Electric Co. can not obtain user and generate power for their own use
The purchase sale of electricity price difference of electricity is an actual loss for local electricity company.Both the workload of power grid had been increased, had not had again to power grid
There is actual benefit, therefore can set various reasons that the investor is allowed not select this connect-in strategy.
Based on the above, a kind of solar powered method that can effectively improve solar energy power generating utilization rate is provided
It is necessary.
