Tigo TS4AO 500W

I have a question regarding to the Tigo TS4-AO.

I have 10 panels half cell 34 Vmp, of which 7 with optimizers due to complex shading in the morning. 

I don't have a TAP or CCA. 

I see when my last panel comes out of the shading the power spikes to all 10 panels. 

If not i have only power from 10 x 10%. 


What happens if 1 panel is fullly shaded with the optimizer? It goes into bypass? I should get 9 x 100% right? Or does is it need to have the 16V to enable the bypass mode?

    Hi Rob,

    Great question!

    As a general answer, Tigo optimizers are not bypassing diodes. Our product is a DC-DC buck converter; therefore, we can "convert" the voltage of each panel into higher current, in this way you can match the highest current in the string and allow you to have the maximum potential out of your string. This is much better than bypassing diodes because you effectively use the power from shaded modules and at the same time reduce hotspots from the back of your panel.

    I suggest you have a look at our documentation in >Download >Technical Documentation>Whitepaper - Optimization with Impedance Matching and Predictive IV where our optimization mechanism is well explained.

    If the voltage in input in the optimizer is below 16V, the TS4 won't be able to turn on and therefore start working.

    For your particular case, we would need to investigate a little more. As there is no monitoring installed troubleshooting requires a bit more attention. I have created a ticket for your case,

    Wishing you sunny days,
