PVSOL 2018/2019 and single Tigo optimizer


Recommended Posts

Hi Andrzej,

you can connect the power optimizers in any imaginable way. Also only one per string, although this is not recommended. See this configuration for example, where I connect 5 modules in series on one Tigo TS4-L 32V:


Keep in mind however, that the Tigo optimizers are not designed for such a configuration. The voltage and current ranges and also the power levels are designed for one module only, perhaps two if you have bad lighting conditions.

If you want to configure a string with e.g. 9 modules without and only with power optimizer, you can do the following with the polystring feature:


Hope that helps, kind regards,
