Mines mppsolar but I believe they're basically the same. But yes mine acts exactly the same. There only 3 months old. But firmware version is 73.07

I'm using 64kwh of lf280k 2 x 2p16s with 2 seperate BMS I will check but I think they're both set higher

Hello My inverters won't charge the batteries at more than 100a each 200a combined even with the max charge rate set to 150a. There seems to be some sort of hard limit they won't go past no matter what. Solar panels will produce more power if building demand goes higher so I know there's more capacity to charge but it just won't draw over 100a from the panels

H̶a̶v̶e̶ a̶l̶s̶o̶ d̶i̶s̶c̶o̶v̶e̶r̶e̶d̶ t̶h̶a̶t̶ t̶h̶i̶s̶ f̶a̶u̶l̶t̶ o̶n̶l̶y̶ h̶a̶p̶p̶e̶n̶s̶ w̶h̶e̶n̶ t̶h̶e̶r̶e̶'s̶ n̶o̶ s̶o̶l̶a̶r̶ This was incorrect I must have just fluked a couple of times I have however found out: Inverter one in single mode set to sbu with grid switched on has really unstable current draw from the battery however if I turn grid off it goes very stable. Inverter two in single mode set to sbu is extremely stable no matter grid position. Please see videos showing this https://photos.app.goo.gl/6q1UgCzXPgCEi9758

I have an issue now my system is all commissioned where one inverter throws a f60 and the other throws an f08 sometimes other faults. This only happens when switching the grid on to inverter one (left inverter) What's strange is I had this system working as far as I could tell on a previous battery (only 3kw) but only using sub mode while waiting for the main battery to arrive. Now with my new battery (64kw) I'm unable to have the system fully running without throwing the above fault codes. The only way I can get the system to run is switching grid off to inverter one. With everything else connected/on it works. As soon as I switch on grid to inverter one it trips. Please see video of what happens here: https://photos.app.goo.gl/tGYDiB2pFky5EhhPA Regards, Jeran

Basically as per the title, my loads arnt perfectly split down the middle so ideally parallel would suit me better however are there many benefits to running them separately besides transfer time? Inverters as 2 x 11kw max's

The colours have changed because I've moved my strings around so the shaded panel only effects 6 panels instead of 9

Bit of a weird thing I've realised. When one of my strings becomes shaded they both drop off before one recovers but jumps up and down on volts and Amps The first photo is what is what I would expect and the the other two are the issue I'm referring to

No Problems, Any one on here willing to share their label and firmware from factory. Ideally MPP Solar Branded. for an 8kw

I have contacted them regarding a fixed firmware for the 8kw would either @Coulomb@Georg594 be able to send me a photo of your label and firmware it shipped with, Ideally a photo? And I shall try get a fixed Firmware for yours too

I'm really happy with this latest firmware update still not perfect but it's massively better than the shipped firmware. Anyway these fixes could be ported to the other inverters? @Coulomb @Georg594

Not sure on the 7.2 I'm afraid

What model inverter do you have? 8kw 11kw? Removable display?

Based on what I've witnessed over the past couple cloudy days I would consider this 95% fixed. It still sits at around 100v longer than I would say is perfect. However it does get going much quicker without missing out on too much power. I would say that over the course of the day I'm loosing no more than 2-300wh. Not sure if this fix can be translated into the 8kw model but that is beyond my scope of knowledge.

No, the update I supplied is for the 11kw max 1 ONLY
