Minor obsructions can have major effect on string performance. Kink in the hose effect on older and cheaper inverters is very significant

If you look up the Danish report itself you can see that the differences under all conditions are within 2%.

Good stuff, shows that modern inverters with 'gobal' or 'extended' mppt, like SMA and Fronius, are en par with optimisers under basically all conditions. This appears to make optimisers obsolete. This reduces the number of points of failure and purchase costs

I never intended to buy a monitoring system and no upgrade has occurred. Tigo rang up a couple of months ago offering assistance (a temporary monitoring system install) or straight replacement (I presume with updated software). I agreed and suggested they choose the most convenient option for...

Not according to my experience from 6 units bought in June 2022. Tigo has been very slack and ad hock at their responses. Not that I have pushed it, in a way I accept having fallen for their tricks. I just want to see an end to their crook practices

I talk from personal experiences from this retired technician which backs up installer Mark Cavenagh's experiences. Posts and people regurgitating sales pitches and promotional material are not convincing for me. Thanks for your response

That is not the way I see them advertising their gear nor di I see this in their manuals. You are invited to back up your beliefs with evidence

No for Tigos, see report elsewhere. I found they just sit there not making any difference. Could be different if connected to a monitoring system after a software update

They are talking about parallel panels in a string on their page. The unevenness comes from using panels with different power capacities or putting panels in parallel doubling the theoretical current (en power) production capacity. Yes Tigos can compensate for unevenness within one string up to...

Re: Strings of mismatched panel specs and/or parallel strings of differing lengths are the situation where Tigo optimizers add the most value… Cannot follow your thoughts here. Tigos are supposed to optimise the string they are part of, they have no function accross different strings. Tigos are...

Tigo optimisers cannot capitalize on the bypass diodes since the voltage accross a bypass diode (0.7V) is far too low to drive electronic circuitry of a Tigo. Tigos are not capable of utilizing bypass diodes while they are being powered by the panel. Only an independent power supply for the...
