    Tired of clamping with my meter each string to read voltage and current I thought of these chinese panel meters

    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...

    Hall Effect Sensor Split Clamp to Monitor Output of Each Individual Solar Panel???

    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...

    Spring overcurrent panel production makes both of my inverters trip

    "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...

    Spring overcurrent panel production makes both of my inverters trip

    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...

    Spring overcurrent panel production makes both of my inverters trip

    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...

    One string not reaching the inverter limits it still overcomes the inverter that shuts down and restarts

    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...

    One string not reaching the inverter limits it still overcomes the inverter that shuts down and restarts

    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...

    One string not reaching the inverter limits it still overcomes the inverter that shuts down and restarts

    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...

    One string not reaching the inverter limits it still overcomes the inverter that shuts down and restarts

    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...

    How to adjust the Growatt SPF5000ES to allow the batteries to take the full load during the night

    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...

    One string not reaching the inverter limits it still overcomes the inverter that shuts down and restarts

    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...

    How to adjust the Growatt SPF5000ES to allow the batteries to take the full load during the night

    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...

    How to adjust the Growatt SPF5000ES to allow the batteries to take the full load during the night

    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...

    Have two Kostal Piko MP Plus 5.02 that have benn running fine for more than a year

    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...

    Connecting two inverters to one battery bank off grid

    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.
