DS-100C Operating Manual
Appendix D - DS-100C Technical Specifications for the values of load
capacitance for each position of the voltage-range switch. For example, if using a
load capacitance value of 0.005 F (low range), and a PV system with an I
sc
of
20A the rate would be:
Rate = 20A/0.005 F = 4000 V/S.
When comparing this value to the PV system, it is best to normalize this rate to
an individual PV cell. This can be done by dividing the rate by the number of PV
cells in series. If the previous example had fifty cells in series the rate of each
cell would be 4000 V/S÷ 50=80 V/S. Different PV technologies vary in their
sensitivity to the charge rate. It is left to the user to determine if there is reason
for concern. Often the PV module manufacturer can provide information
concerning how quickly an I-V curve can be swept on their modules. Daystar,
Inc. will also provide any assistance possible.
