Thanks all for all your information and time you spent trying to educate me. I think I will stick with the Enphase. My configuration for those who are catching with my project 5 panels on a wall facing West 3 panels on a lower roof facing SE 3 panels on a lower roof facing NW I have not...

ok but do you have the same limitation than string inverter ie have a minimum of panels per string (minimum voltage) for the inverter to start converter DC to AC? As far as I can tell this solaredge optimizer is nothing else than optimizer like Tigo and a string inverter.

For info @Andy1733 you can resize the images. They fill 4 times my 27" 4K screen lol

I do not know the detail either but what I know is that effectively some hardware must be compatible in order to connect to the Octopus database so the BMS/Inverter knows when to export at the best price. As for the smartmeter I do not know. I managed to resist it until know but I think this...

Do they have a similar issue with the minimum voltage required, like a typical string inverter?

I do not have yet my new system, I only have FiT. I was just wondering if someone managed to sell at that price. Regarding your question. I believe this is the job of the BMS depending on how you have prioritized it.

Hello I know this is an old post but I thought I'll share my experience. I got my system installed in January 2016 2 days before a change in the FIT (so they were all crazy mad to install all the systems before that cutover date). The electrician came on a Sunday around mid-day to finish the...

When (hopefully not If) they acknowledge that they forgot to connect some panels or that they install them all on the same string while you have a 2 string inverter, it will be time to discuss money because during all that time you lost in generation and therefore money. You have already...

Hi Jena I am glad you now better understand the technical aspect but all this would have not been possible with a dose of common sense that led you to think something was wrong. There could be several reasons for those cables. Just throwing hypothesis They expected to connect the panels to a...

Hi Jena sorry if we brought with confusion with the orientation of the panels. Effectively with your set up (South and South East with a 22.5deg difference) the situation is not as extreme as for a 180°. Nonetheless, unless you purchased knowingly a one string inverter. It is always best...

This screenshot is from SolisCloud but from a web-browser. Not sure what info you have from the app but you could simply log to it from a web browser

If this is confirmed all the panels have been put on one string and knowing that half of them are facing a different way (opposite direction), I think it would be fair to say that they have not installed the system for optimum performance. @Jena Please check carefully your system (number of DC...

Who managed to sell some electricity today.. it peaked at nearly 1.80 pounds yes pound not penny.

Jena, You should have one DC switch per string. The DC Switch is the black one we see on your photo. I assume you have a online logging to see what your panels/inverter are doing. Mine looks like this This is the two string (PV1 and PV2), right now as you can see they are producing...

I have had my inverter in the attic since January 2016 and so far no issue. It has a built-in thermometer and I saw last summer that the temperature had reached 64 (while the operating limit from the spec is 60) at some points I am considering adding extraction fans when I will add my new...

Hello The Enphase product IQ7 and now the IQ8 are micro-inverters. That means that each panel must be equipped with one and become independent. It is like having an inverter for each panel and this is it. Thus the name micro-inverter. It has if your panels would output AC...

and what made you go for HV batteries instead of LV?

As I understand the Triple Box. without the parallel box, you currently need the Master and you can add up to 3 slaves. With the parallel box you do not need master anymore and you can have up to 2 x 4 batteries (2 strings) Without Parallel box . max is 5.8kWh (from Master) + 3 * 5.7kWh...

Hello @arwooldridge Thank you for joining the conversation. I understand you are the proud owner of a Solax Parallel Box. I read the datasheets and manual from the Solax website and unfortunately, I could not find a list of support batteries. I understand though that there is no need for a...

I did wonder this but I have noticed similar things for all LV and all HV. but then when looking at one battery. the HV has already a higher voltage to start with. This means the cells inside are also connected differently? Anyway, this thread is about why to select a HV rather than LV (or...
