Apart from the risk of getting electrocuted, I find that every time you need/want to check the input of each string coming from my roof is also cumbersome and rather useless, since by the time you check one (and I have 7 strings)... the reading is already old by the time you have read the next...

Funny I was about to start that same question OffGridForGood just mentioned, so thaks for saving me all the time to forward that same question; also thank FilterGuy for forwarding all that interesting data from Fonrich. What I was looking for was the same OffGridForGood has mentioned; in my case...

"Generally speaking, most regions needs at least a ~15% buffer between panel Voc and max MPPT voltage" I believe that is the case; the installer never took into account that 15%... I have now been trying to read all readings and even though it was almost impossible to achieve, including the...

Hi SeaGat, That is another puzzling problem I can't understand, because the Voltage checked with a good tester NEVER reads over the 600V DC that both Kostal MP Plus 5.02; it actually reaches around 520-530 DC voltage when it trips in the case of both inverters. The watts should reach 5000W, but...

Good morning to you all.. I have mentioned this on other threads, but still haven´t sorted out my problem. It is a fact and now I come to learn about it that during these periods, when we have clear skies or even with slight white cloud presence, and the temperatures are still low in early...

As I mentioned earlier, my photovoltaic system goes back to 2017, when I installed my first 8 panels and a Kostal inverter I no longer have. since then the system grew year after year and now I have a total of 69 panels that range from the first 8 with 230W and 24V to the latest ones JA Solar...

Yes timselectric, you are right; over here in Spain to us earthing and grounding are the same and when done to the panels, my eathing means sending one ground/earth line all the way to the main junction box and connecting it to the general ground array. Actually it is "not allowed" to install a...

Hi Mattb4 and thanks for your comments, In deed I have tried disconnecting the offender string and since the only two strings that go over the 500 Volt were on the same Kostal inverter, I immediatly swapped one of the strings to the other Kostal inverter (the rest of the inverters (DEYE and...

Hi timselectric, thanks for your comments; Regarding the earthing of the panels, in the area where I live professional installers all agree that being a mountainous area with many Spring/Summer storms, earthing the panels on the roof make it an attractive target for them, so no one as far as I...

Thanks to all, great buch of people!! I was thinking (or inventing) such an automatic switch where I could adjust it to where my Kostal inverter/inverters are giving me the error and switching off and reset itself as soon as the voltage dropped back down, but even after doing some search on the...

I'm having a bit of a problem from one of my 7 strings; my two Kostal Piko MP Plus 5.02 inverters can take as much as 600 V from either of their two MPPT's and 5.500 W, but for some reason one of the strings as soon as I reach 530V and producing 4.200 W, the inverter shows an error stating the...

Hi boenjames, I have tried SBU and SOL but I keep getting grid usage between 200 and 400W, while the battery takes care of the rest (200-400W) ; that is why I believe that I have some setting on the Growatt limiting the battery feed...

Dear friends, I have the Growatt SPF5000ES and 7 batteries (Pylontech 6 x US3000C and 1 x US5000) amongst other elements, including 56 solar panels, but the issue I want to solve is related to the Growatt inverter and the 7 Pylontech batteries connected to it. From 6 PM in the evening to 11 AM...

Dear Colleges, My inverter "collection" is composed of several inverters; I started in 2017 and a lot of mods and adaptations have taken place since then; right now I have four inverters, all connected to the same grid and each one taking care of their share, from my 7 strings coming from the...

Thanks houseof ancients, in my case I live in Europe and only have single phase 230 V AC. I thought of using a splitter box so one cable leaves the battery bank, one cable ===>splitter box====>two cables, one for each inverter.

I agree with you jfpetesn, you can invert the black and white wires on the DEYE, but that can lead to future problems when someone notices the wrong wire placing and tries to fix it by swapping them for you.. And anyway, there MUST be a correct way and that's all I'm asking for..

Dear friends, I know this has been discussed before, but I still don't see it clear and the problem is that different user manuals of the DEYE Sun 5000 show opossite orientations. I now have been working on my main general cabinet and everything is disconnected, but I need to know which is the...

Yes, no problem.... I'm not sure about that statement. As an example I have one DEYE Sun 5000 and a Growatt SPF 5000ES; right now the battery bank is hooked to the Growatt, but would like both inverters connected to the mentioned bank. Problem is the battery only has one comm cable that came...

I have 6 x Pylontech US3000C and 1 x US5000. My house lives on batteries every day between 6 PM and 10AM next morning.. The problem with the batteries is that you must have enough SUN hours to charge them; using the grid is obviously not a clever move..

Thanks DIYrich, I actually have two electric 200 liter (53G) water heaters and they are both at 60ºC (140ºF); managed to charge them during the day.

Lucky you Ampster, Where I live I am not allowed to dump the excess to the grid, for several reasons, but it is a fact. My battery covers the whole house consumption from 18 pm till 10 am. I use a mechanical timer because I don't trust the programming they arrange on the other side of the World...

I guess that only a few people who live close to the Equator or in very dry places might not be in the same situation and have the same dilemma as most of us do. For that reason it is my believe that someone has come up with a solution where you can adjust the panels production according to the...

The problem I see with this timselectric is that each inverter has a limited amp delivery from the battery pack, while if you use both inverters "in theory" you could supply more power to your home while on batteries. I have seen that Growatt has an RS485/CAN HUB that is thought for when you...

In my case I have a Growatt SPF5000ES and a Deye Sun 5000 and as backup I have 6 Pylontech US3000C and a US5000. I can connect the battery to either inverter, but logically the best would be for the battery pack to work with both inverters; you just need a good set of busbars and powerfull...

And Damaged it was. However I got help from Growatt CN and they gave me all the help I could get, I was actually surprised that even though I had no help from my rep or european representatives for that matter, Growatt China made the right move in trying to help me. In the end and after...

Thanks anyway ProfLinux, and I fully agree with you, I actually asked Pylontech CN that same question and this is what I got as reply: "Our battery has a protection system and that is why the BMS has alarms and the battery stop working to protect the battery cells." Can you believe it?? So in...

Hi SV Lyric, I have 7 Pylontech 48V batteries (one of them being an US5000) and none of the red buttons stay in after pressing; this buttom is just a press and release device, just like a door bell button. It might just be some dirt that is blocking it... One way or the other, it shound not stay...

Purchased two months ago to add some storage to my 6 x US3000C battery bank; it was a bit complicated to get it to work together with the other batteries, but in the end almost everything was fine (I say everything because there was a delay on the charging process, being the US5000 the last to...

Will do so, and thanks a lot once again; I will however contact the supplier here in Spain to get the go ahead or whatever they say. Best regards and enjoy your weekend! Spanish Flyer

Thanks again Kirkdis; following your comments, I arrived to this screen; to me means nothing, but I'm sure you can tell if I need updating. Don't want to keep you up so late, so you can reply during this weekend.. Thanks again HERE IS THE IMAGE

Thanks Kirkdis, have no idea of wht the firmware version is... Where can I find this??

Have just removed a Growatt spf5000es due to failing to run, but since I couldn't wait till it is repaired (if at all possible and probably a lengthy period of waiting time), so I installed a brand new one. This one is working perfectly except for one fault (21); according to the manual it...

I am sorry to say that I have the same red led constant on a brand new Pylontech US5000 that has worked great for the past 2 months and have tried all that I can think of, without opening it, but nothing seems to recover normal operation. The problem with using some kind of external load (at...

Hi to all and Merry Christmas!! I have a grid connected (230V 50Hz EU) Growatt SPF 5000ES and have just purchased a DEYE 5000 Sun. The growatt is doing fine, with 8 x 455W panels and 7 Pylontech Batteries (6 x US3000C and 1 x US5000). Now I want to feed the DEYE with the outlet of my Growatt...

Thank you for your comments Sidmouthsteve, In the end I went for a complete new setup; I agree that the LV batteries will soon fade away. In my case I have purchased a Growatt MIN 5000TL-X and a 7.6 kW ARK HV battery. Now it is a question on how to configure the system with both inverters; I...
