    Deye: PE and case Grounding

    I think you get L and PEN (PE + N together) from grid (TN-C). You need to separate the PEN (TN-C-S). So PEN to PE busbar. Connect local grounding rod to this busbar too. A different N busbar ... connect PE busbar to it. It is "the bond". From here you have a different PE and N ... connect...

    Fault/ warning 32. Help please.

    There is no Fault 32 ... only Warning 32 :) http://www.mppsolar.com/manual/PIP-MAX/PIP%20MAX%2011KW%20manual.pdf The error is: "Communication failure between inverter and remote display panel" So your display is not plugged in correctly :)

    ARC fault

    I am not sure AFDD could catch little arks like these. Here they tested (with DiY lego tester) after how many Watts will the AFDD disconnect if there is an arc. Also ... epic AFDD song ?

    Do they want to kill grid-tie solar systems ? Now when the whole EU is in energy crisis ? 20 French nuclear reactor is shut down for maintenance ... Germany blow up 3 .... propane prizes gone through the roof ... Russia stopped propane export to EU. So this winter we have enough in storage...

    Worst than horrible ? Which country is this ? It makes no sense to sell a Wh with these conditions.

    You have a 1:9 sell/buy ratio ? Where? Residential or industrial tariff ? Horrible :o The almost 1 EURO price too. The 1:6 ratio in Germany is bad enough. But this ... really makes no sense to sell anything to the grid. And the utility company sells it to your neighbour with 9x profit.

    Here in Hungary we have a balance tariff. And it is a yearly balance. So what you sell on summer you can consume on winter. If you overproduce and the sell-buy is positive then you got almost nothing for that. But who cares if you can heat the house in winter from the summer PV generation.

    The price was about 0,37 €/kWh for 2021. Now I made a price calculation for a yearly 5.000 kWh in different cities in Germany (2023 prices). Berlin : 2.583,30 € -> 0,52 €/kWh Hamburg: 2.619,30 € -> 0,52 €/kWh Frankfurt: 3.538,49 € -> 0,71 €/kWh München: 3.592,37 € -> 0,72 €/kWh...

    This is not EU. It is global. And you still do not understand the hybrid inverters. Only AC coupling. No other workaround. If you know any other, please name it :) You are completely wrong. Still ... you do not understand the "WITH GRID SUPPORT" part :D Did you never saw an MPP Solar...

    How to solve N/G bond problem with my cheap AIO ?

    First hybrid means grid-tie + off-grid. That can sell to grid. Please learn first the name of the system EASun started this marketing BS that they sell Hybrids ... because it sounds "better" Really they only misleading the customers. They sell Off-grid (with grid support) inverters...

    How to solve N/G bond problem with my cheap AIO ?

    Does EASun have a support ? :devilish: My only experience is that they want to get rid of you. And even when you reach them ... non working Firmware upgrades, do not want to replace dead on arrival inverters ... etc

    Nope. You did not read my post thoroughly. EU is basically Grid-Tie only. Different types of grid-tie ... but only grid-tie. Again, read my post. Off-grid with grid support systems HAVE GRID ! And this is nonsense. If you have a simple Grid-tie like Fronius Symo/Primo, SolarEdge, Huawei...

    Ireland is a part of EU that I know very little. Germany, Austria and the neighborhood I know. Here there were the off-grid installs non existent. Only for some farms or chalets which is too expensive to connect it to the grid. Grid-tie's however are common (5-50 kW average 9kW). Like in a...

    Newbie from Portugal building a house :)

    Nope. EU is waaaay behind US in off-grid system installs. We have a LOT of grid-tie ... but off-grid way less (hybridized grid-tie's without backup box count as grid-tie, sincs in a blackout they stop working even they have a battery installed). In the last 2 year it changed but still there is...

    Hybrid Inverters - Split load between PV+GRID

    Not recommending EASun. Not because it is a cheap clone of the MPP Solar inverter. But we had a lot of problems with them. Loose screws making short circuit inside. Cables not connected in the inside. Dead on arrival ... etc. And EASun does not like to replace it under warranty. If you fight for...
