    Hello, consumption meaussurement over three pases would be usefull in any way you try to realize a zero-export function at an common three-phase household. One phase meaussuring isn't helpful in most cases.

    MPP Solar / Infinisolar MPI 10k hybrid inverter died - fuse goes off when synchronizing with grid

    Last weekend I changed the mainboard and yesterday I startet the inverter. But as I turned the solar-input switch at the bottom of the inverter to "on" I heard a sizzle at the same second and a little smoke came out of the right upper side of the inverter. Now the inverter goes in an endless...

    The new mainboard for my MPI 10k arrived positive: shipping war very quick and took only 1 week from Taiwan to Germany negative: 110 USD shipping costs have to paid from me Here it is. Seems that it's a new revision with a slightly different pcb layout I 'm going to insert the new...

    MPP Solar / Infinisolar MPI 10k hybrid inverter died - fuse goes off when synchronizing with grid

    no this aren't cracks, it's a kind of white dust. I can't find the missing resistor. Either it slided deep inside the inverter while carying it the way through my garden to the shed, or it exploded completely

    MPP Solar / Infinisolar MPI 10k hybrid inverter died - fuse goes off when synchronizing with grid

    after several discussions MPP solar is willing to provide a new mainboard for free but with shipping costs of USD 110. They do not accept it is within warranty time but a one-time goodwill. I think it is because I write the process of warranty transaction of MPP Solar public at this forum (and...

    MPP Solar / Infinisolar MPI 10k hybrid inverter died - fuse goes off when synchronizing with grid

    I had contact via mail with MPP-Solar. They told me to make some tests and I made a video of this and send it to MPP-Solar. After analyzing the video they suggest that the mainboard is defective. It is sad for me that the inverter dies after 11 month of usage only, but much more sad that...

    test 1300w grid-tie inverter

    Hello, did anybody compared the GTI 1000 / 1200 / 1300 models? Maybe they are the same inside. It's just speculative but 1st I saw this with the cheap GMI micro inverters, I tested the 260 / 300 / 350W models and they are all the same inside and deliver 300 watts. 2nd on ALiexpress I only can...

    für das Lademanagement ist der Wechselrichter zuständig, das BMS überwacht die Zellen. Das sind zwei unabhängige Prozesse, dazu müssen WR und BMS nicht kommunizieren.

    MPP Solar / Infinisolar MPI 10k hybrid inverter died - fuse goes off when synchronizing with grid

    I installed a 3-phased circuit breaker and swapped two phases, thats why the "phase loss" error sowed the first time. I changed it back but there are some new warning messages
