Embodiment
Controller for solar of the present invention comprises charging circuit, storage battery and discharge circuit and the lightning protection inductance that is connected in parallel, and wherein, the lightning protection inductance is connected with storage battery, and the lightning protection inductance perhaps is set respectively in charging circuit and discharge circuit.As shown in Figure 2; when thunderbolt takes place; lightning current Il releases to lightning protection device and back level charge circuit, load circuit etc. by circuit; Lc1, rc1 are respectively the line inductance and the line resistance of input charge circuit; Lc2, rc2 are respectively the line inductance and the line resistance in load discharge loop; rb1 is the internal resistance of storage battery, and rQ1, rQ2 are respectively the power switch pipe on state resistance, and D1, D2 are the Transient Suppression Diode of protection power switch pipe Q1, Q2.The lightning current that flows through lightning protection device and back level charge circuit is respectively Iv1, Ic1, Ic1 is divided into the multiply electric current again when level is released backward, mainly contain the

internal resistance during much larger than the lightning protection device conducting, the lightning current that flows through charge circuit has just greatly reduced.When coilloading L1=13uH, by actual measurement Ic1: Iv1 ≈ 1: 20, within the transient current ability to bear of switching tube and Transient Suppression Diode, when adding L1 and be 380uH, actual measurement Ic1 has had only

lightning current of 20KA.When exporting the discharge loop lightning test, the L1 inductance has also play a part same, and by actual measurement, controller output discharge loop can not be by the thunderbolt ripple test of lightning current 5KA, during the thunderbolt ripple test of 5KA ninety-nine times out of a hundred controller all can damage.Add when L1 is 13uH, then can test by the lightning current of 20KA.Simultaneously, controller input charge circuit often is the multichannel input, and position coilloading in Fig. 2 can be imported charge circuit to multichannel simultaneously and work, need not every road coilloadings all.In addition, behind the coilloading, greatly reduce owing to flow through the lightning current of storage battery, the induction reactance of inductance is much larger than the internal resistance of storage battery simultaneously, the residual voltage of being divided at the storage battery two ends is also corresponding greatly to be reduced, and the lightning protection capability that has so also strengthened accessory power supply, control and sample circuit has also greatly strengthened.Can cross actual measurement, confirm this point yet, before the coilloading, accessory power supply input circuit and sampling input circuit often do not damage when carrying out the 10KA thunderbolt, have added behind the inductance and then can test by the lightning current of 20KA.D1, D2 are Transient Suppression Diode among the figure, and they have current response ability fast, can reduce the vent flow of the open pipe utmost point, reduce the damage probability of switching tube.Be to increase protection to switch, also can be at same position parallel discharge pipe or high frequency capacitance, also can be simultaneously and Transient Suppression Diode and high frequency capacitance, or simultaneously and discharge tube and high frequency capacitance.Solar cell input source among the figure also can be other DC source input, or the DC source of AC power through forming behind the corresponding current rectifying and wave filtering circuit.In addition, include main control circuit, input voltage and input current sample circuit, telecommunication circuit, alarm imput output circuit and output voltage current sampling circuit or the like functional circuit for the control circuit in
