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.

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...

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

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...

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...

Hello, because the prizes for solar equippement raises very high I am looking for a cheap grid tie inverter. The cheapest one on market are the "GTI" series. Different models with 300W / 500W / 600W (not enough power for me) 1000W 1200W 1300W Maybe they are the same inside. It's just...

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...

Question to the Revo owners: I am thinking about buying a Revo 5.5k I am going to build a new solar system which I am planing at this moment. It will be something like this, on the ground but with 9x 380 watts But I am uncertain with some facts - I am reading several times that the Revo has...

this can be found at the 2nd answer in this topic:

me too after knowing hoch much this work is :-D Oh wait, just building some more powerwalls with another 7.200 cells right now. I guess I am unteachable...

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

was genau erhoffst Du Dir davon?

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

my MPP SOlar MPI 10k seems to be broken :cry: Maybe someone can help? -> MPP Solar / Infinisolar MPI 10k hybrid inverter died - fuse goes off when synchronizing with grid

Hello, after one year of usage my MPI 10k seems to be defective. You can see the whole project here -> 100KWh DIY 18650 Powerwall in Germany Without grid connection it runs fine, but when I connect to the grid then the external fuse (Siemens 3x B16A) goes off. at minute 0.50 - I...

Hello, does anybody modified the CT of a single Revo2 so it can meassure 3-phase?

I guess you have to find out if your system is able to communicate with the battery or have to communicate with the battery. I don't know Pika but the voltronic inverters (MPP Solar, Infinisolar, AXpert ...) have a communication-port for some batteries e.g. the integrated bms inside the battery...

prices, location and shipping costs would be helpfull - for you and for possible buyers

sorry, but the point of view of the picture above is not very good, but at the following picture below you can see the gap between roof and modules better. It's bigger than the roof overhang and shadow comes only when sun turns over to the west side. The balcony is exact east sided

these effects appear when combining small amounts of cells in parallel befor connecting them serial - in combination with huge currents. I don't do both of this. I am using huge amounts of cells in parallel (60pcs or 120p per system, and because I have several complete 14s systems parallel...

Can you please explain that? In my opinion different manufacturers won't be any problem, electricity doesn't know about brands ;-) And different internal resistances will cause that the cells with lower values will have more load than the ones with higher resistance. Same thing with...

sorry, I did not wrote clearly. I meant: running in parallel is not the problem, but starting the bms via a 5V impulse on B- and P- while there is some external voltage on the P- too may damage the bms. I guess you have to cut the external voltage before starting the bms. you are totally...

here we go, the three systems inside the locker at the garden shed the moment of connecting now that it works I can do some cable management cables for the voltmeter and...

on the right side the two older systems, left the two new with identical capacity at the app there are four systems now because the voltages didn't fit there is a huge current at the moment of adding the two new systems to the older ones 4,5V difference...

the last two weeks I finished my powerwall project. On the ToDO list: 28 batterie packs 60p At the end it's more effort then the bigger 120p packs because of twice of the amount of busbars I solder the fuse wire in one piece and at the end I cut the...

after some research I only found two charge controllers which will fit the 65V. - MakeskyBlue v118 and v119 (maybe the clone from PowMr can do as well) -> round about 160USD for the 60A version - EPever Tracer AN series -> round about 300USD for the 6415AN = 60A version Last weekend I found on...

oh, that's interesting, never heard of some failures before, I guess I will search the forum to find this cases. My guess (not proofen): when starting up the BMS while there is a voltage on the "P-" (maybe because you have two or more BMS in parallel or because the charge controller is running)...

I went to the doctor because I felt ill. Good news: it's not the Covid-19 virus - but another kind of virus The Doctor has no idea how to cure the symptoms ? maybe you do? Please help.

ready connected and running now there are 50 KWh of total capacity up and running the next batterypacks with an estimated total of 20 KWh I will try to complete this build within the next week

then carrying all the parts to the locker equipping the shelfs and walls with the prepared fermacel plates...

for those who lost overview what's going on in capacity: actual there are 50KWh read to use 11 KWh in the old pigsty at the Infinisolar E 5.5KW with 2,8KWp on the wood storage 27 KWh for the garden shed at the MPP Solar MPI 10k with 9,3KWp on the roof of garden shed. The battery packs are not...

despite it's -8°C work goes on. Sanding the locker for new painting some holes for the 35mm² copper wires black metal protection paint while the paint is drying I prepare the inner parts 10mm...

40mm / WLG 0,32 / fire proof 1.000°C and above preparing for welding the shelfs are 300 x...

before the next step starts here a video of the actual project status (you may activate subtitels) disassebling the last few ebike battery packs their are all chinese OEM cells from FST, BAK or noname disassebling of most...
