@johnbrzezinski1446 yeah I don't know where that would come from the Tigos just hook onto the panels it doesn't care what other set up the system has. Works great I don't see why anyone would think that that would be an issue, you could use any version of tigo or other brand that you want with the dpu. Other brands won't care.. they are not tied together in any fashion.
Hi good afternoon. Thank you for posting the video. I am looking at setting up the exact same system with 54x panels (8 strings - 2 going to each of the Ultra's PV inputs). How many panels do you have ran in series and how do they hook up to your breaker box on the inside? I see you have Westinghouse and Langir 15A mini circuit breakers. Is each HV and LV string connected to their own circuit breaker so the breaker acts as a DC disconnect kind of like the IMO DC disconnects SignatureSolar sells? I would like to pick your brain for more details as I'd prefer this setup instead of 4x IMO DC disconnects.
@raymondhupp1437 hello the max I could get away with was 8 475 Watt panels in series as that is the voltage input the high would take you can send more current in but you cannot over voltage you'll damage it but you also don't want to send too much amperage. Yes I have the disconnects they're in their mainly as a disconnect a little bit of a safety but again amperage isn't the real killer it's the voltage you cannot absolutely not do go over voltage. So I swapped that Westinghouse 15 amp to a 20 amp because the amperage isn't a problem and the panels I have over the shed just touch 15 amp in Wood pop the breaker but it was just fine for the input. I ran the negatives straight into the inverter solar input and the positives went through the breakers and disconnects.
@bikhard1078 I put in a dedicated AC circuit on backup that the adapter plugs into. And if something should happen 12:24 volts is easy enough with the batteries around to get the panels to kick back in gear and charged with the batteries.
Is there a cheaper option for rapid shutdown if you don't need the data logging? Spending nearly 50% of the price of the panels for something that you "may" never have to use sounds ridiculous IMO.
@@TheNature101 I'm not sure you could Z-Wave a switch to Google or Alexa if I had to think about it but I went to this because it was required by code personally
Tigo also makes a TS4-a-f that is a rapid shutdown module with no optimizer, or the TS4-a2f where one shutdown unit handles two panels. Then there’s a little 12v power supply and transmitter with a “core” that you run your negative PV wire through- and that sends your “keep alive” signal in the PV wire to the modules.
How interesting that I was just looking for a demonstration while thinking about EG 4 inverters and batteries. Thank you! As I understand it the button needs power. I haven't researched much into this yet but my kneejerk question is, if the power is out/grid down and you have to hit it will it still work? Or I guess I should ask if its tied into the batteries for power?
The tigo CCA "transmitter" needs power yes, I have it on a battery backed up circuit, so when the power is out as long as I have some battery in the ecoflow it will be powered, and I have it setupo on the smart home panel 2 that that circuit will be powered to 0% battery.
@@erickbostrom4049 Can you explain why you need to power the power button when the grid is down? My understanding is that, if the grid power is down, also the solar energy MUST be down? - My understanding is that if the fire marshals turn off the power of your home, or the power of the whole block, the solar power of your home must also be down automatically without having to push your security button, so the fire marshal can enter inside your home or access your roof without any risk of electrical shock. - The shut off button is a security switch allowing you to turn off all the solar energy so you can access your roof for maintenance without having to turn off the grid power to your home. - Now, if there is a power outage, then you may want to have solar energy available, so maybe you need then to be able to have solar energy, using your solar panels during the day or your batteries during the night, so I imagine that you need then to power the full solar energy system using a battery backed up circuit (or UPS) but this should be only a temporary by-pass solution? Please, tell me if I am wrong in my understanding, as I plan to install such system.
What a great question. Well... My system is self-consumption only, I use and store my power. I am NOT grid-tied so I do not need to worry about back-feeding the grid "nor do I want to". With that if I want my panels "ON" I need to power the CCA, so IF the grid is down that is irrelevant to me as I would only notice if my batteries are low and the SHP2 used its built-in transfer switch to transfer to grid power until my batteries come up. If that is the case I still do not back feed "Grid tie" to the grid so I pose no risk to workers that may be on the lines as I am only a standard sub-panel set up on the main electrical panel, so if the panel goes off so does "Grid" power to my system SHP2. If something ONSITE is happening then the emergency button would turn off all the panels for 1st responders needing safe access. I do see your point on the inverters shutting down as well as the panels to stop the internal AC as a safety but I do not have an answer on that part. I know cutting a line obviously pops the breakers to stop the flow but I see your bigger point of ALL AC in the house. maybe that function is a business opportunity?
@nihongobenkyoshimasu3190 here is what Ecoflow had to say about the AC side rapid shut down: Dear Erick, First of all, thank you for choosing EcoFlow and contacting us. Regarding your inquiry about whether the inverter AC output has a rapid shutdown feature similar to Tigo optimizers, and whether it can automatically cut off the inverter output in emergency situations, we have not yet launched a product solution with these features. However, please rest assured that we highly value your feedback and have already reported your valuable suggestions to our R&D department for consideration. We are always committed to continuously optimizing and improving our products and services to better meet the needs of our users.
Did you Install the panel mounts and panels on the Shed yourself. DIY. How do you tilt the panels straight up at Summer. Seems your shed roof pitch don't allow that to happen?
Yes all done myself and yes they pitch hard south for winter and "mostly" up for summer. I mounted them on a horizontal pole and they "hang" on the pole for winter and are held up in summer. You kind kindnoff see it in the tigo video.

how secure is that wireless signal how easy would it be for someone to hack and shut your system off thats something i have been worried about seeing all this wireless stuff and wondering what the cybersecurity is for those devices
Curious as to how well the Tigo app works. Seems like the panels didn’t show the power when you switched over to that display in the app. Is there just a long delay in getting updates from the modules?
@jeffnhelen the delay isn't in the modules the delay is getting the information from the tigo servers it's a bit of a slow app but it is useful and shows all the power information you want from it.
@@erickbostrom4049 ah ok so it’s cloud dependent then? Would be nice if it was local just in case the internet went down during an outage you could still have panel level visibility.
This was very informative. I had read, somewhere, that TIGO and the Ecoflow Delta Pro Ultra were not compatible, so this disproved that assertion.

On your CCA for your 12 volt supply do you have it hardwired into a plug into the wall? How do you have the 12volt supplied to your CCA?
@bikhard1078 I put in a dedicated AC circuit on backup that the adapter plugs into. And if something should happen 12:24 volts is easy enough with the batteries around to get the panels to kick back in gear and charged with the batteries.

How much did it increase your production?
@KELLYPARRISH did not increase production these are just monitoring units and remote ways to shut each individual panel down.
