This described for me what I needed, and what Tigo's own info could not. Great!

@hesawhat 6 месяцев назад

Just don’t ever try and use the doubles on a flush mount installation. Wire management is impossible, esp. with having to plug in both panels before the string.

@darkenergy5686 10 месяцев назад

Nicely done. I'm still learning about solar systems and this is an important area that I was not aware of. Thank you for the demonstration.

Is it possible to proceed with I-V Curve measurements if there are installed optimizer units in the string?

@SignatureSolar Месяц назад

Unfortunately, IV Curve tracing will not work for any Tigo devices (whether RSD is activated or not). The Tigo MLPE units receive their functional power from the PV Module, and the IV Curve test will present conditions that range from Isc to Voc. This effectively starves the MLPE from its running power and (if sustained) the unit will shut down. support.tigoenergy.com/hc/en-us/articles/215790098-Testing-Methods-for-Tigo-Flex-MLPE-Systems

Thanks !

@SignatureSolar 10 месяцев назад

No problem!

@Issomethinggoingon 8 месяцев назад

Hi I’m about to order 6 O versions, will they work without the tap ? Or are they going to need a firmware update? Many thanks

@leftlink 7 месяцев назад

I have read that they work without the tap for the shutdown function but not for the optimization or data logging. but someone should confirm that is more knowledgeable than me!

@boriskeller1669 5 месяцев назад

sad, that there is no device for Optimization AND Fire Shutdown AND Monitoring. Yes, you can combine them, but who wants to clip 2 modules behind the pv modules with all the risks of defects (and of course the price when using many pv modules). So the m device can really NOT separate the module from the string by command?

@SignatureSolar 5 месяцев назад

Yes, the only way to get all 3 would be to mix and match the TIGO TS4-A-F and the TS4-A-O.

@jessiej3991 3 месяца назад

There is no device like that because they need your money and not because they can't actually make a single module that does all 3 tasks

@scrapyardwars 10 месяцев назад

Excellent results from TS4 here. Optimisation is giving me the edge in a shaded array. Recomended if any shading I have 20 of them.

@Moes_Prep_and_Tech 7 дней назад

Would these work with Ecoflow Delta Pro Ultra Home backup system? It can accept up to 450 volts at 15 amps

@SignatureSolar 6 дней назад

It can work with an RSS transmitter without an inverter so it should work in your application. The transmitter's power supply would just need to be on the same ac circuit as the RSI.

@neomatrix2722 6 месяцев назад

Thank you for sharing I have a question since I'm in ground Mount therefore I don't need these however I do like the idea of being able to optimize having said that I will have a high voltage array with eight panels 480 watts each combined with a Schneider Electric 100 amp 600 volt charge controller what will you recommend for me and how many of these would I need thank you

@SignatureSolar 6 месяцев назад

Hi @neomatrix2722 - I would recommend that you complete a design form and speak with our design team! signaturesolar.com/system-design/#/Welcome

@brucey5585 3 месяца назад

You would need 8 tigo ts4 a O for optimizing. 1 tigo per panel, since 1 of your panel is pretty much the limit of 1 tigo. Then you will also need the tap module and rss module.

@2306cm Месяц назад

We are talking about TS4-A-S, optimizers

@Tiersmoke92555 6 месяцев назад

Safety looks expensive. Do I need to add this type of system to remote ground and none occupied structures?

@SignatureSolar 6 месяцев назад

Whether or not your PV panels require module level shutdown is up to your local AHJ, and you are correct, you would need a TS4 for each solar panel.

@brucey5585 3 месяца назад

Even if you dont have each panel shutdown. Still get an expensive shutdown switch for the array.

@Tom-hb1no 3 дня назад

great video - would these work with tesla Powerwall 3?

@SignatureSolar День назад

No, these are only for DC solar panels.

@Tom-hb1no День назад

@@SignatureSolar thanks for your reply.- Let me restate the question perhaps i have asked incorrectly. If I have Hyperion solar panels and a powerwall 3 for my battery backup for a grid tied system, could I add these optimizers to the panels? Are the optimizers compatible with Tesla PW3 inverter and Tesla gateway 3?
