Question
Spv1040 connection
Dear all.
i am facing a problem when connecting the SPV1040 in parallel. I have 3 solar panels that produce 2.5 V each and i am trying to connect the three SPV1040 in series to have the total of 16.5 volts as output. However, when connecting the output voltage of the first spv circuit to the second spv’s ground and again the third circuit. I have the second circuit conducting current which leads to failure and the out put voltage varies from 7.6 to 10 V.
is there any way to fix this issue?
