  1. 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
  2. The colours have changed because I've moved my strings around so the shaded panel only effects 6 panels instead of 9
  3. 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
  4. No Problems, Any one on here willing to share their label and firmware from factory. Ideally MPP Solar Branded. for an 8kw
  5. 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
  6. 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
  7. 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.
  8. Hello columb the older firmware 57.60 the only difference I found is that it would stick at 115v instead of 90v which it did on the original firmware it was shipped with. After looking at it for a couple days although I think it may be a little too early to tell still it does seem much improved. It stayed at 100v until midday yesterday but it was extremely dark and miserable. Besides there was only 0.5a so not a huge amount to gain. Once the sun did start to come out it shot up to around 290v and stayed there pretty much without fault for a few hours until the sun started leave my panels. See photo 1 Today, bit of odd behaviour on mppt1 regarding amps comparing it to mppt2 but I shall continue to monitor and get back, like I said a bit too early to judge. Photo 2
  9. After moaning that the firmware previously sent didn't fix the issue it just moved the voltage up to 115v they have now sent me another version 57.61. Please see attached. I will get back in a few days with how it responds THIS UPDATE IS FOR THE 11KW Max 1 (with removable display) ONLY. DO NOT USE ON 8KW MODEL Reflash.zip
  10. Hi coloumb, are there.many cases of this inverter getting stuck at high voltage then? I seem to read that it's main low mppt voltages
  11. Right I'm just spit balling here so correct me if I'm wrong. I think that possibly looking at the "minimum voltage" and adjusting that could be the wrong way to look at fixing this. After watching this all morning I have found that it will stay at 115v-120v until exactly the point it hits 3a after this it seems to want to keep 3a or more so increases the voltage SLOWLY until it sits at 3a. This behaviour I think would be fine on newer panels with a short circuit of 10a+. But with my older panels with a short circuit of around 7a in ideal conditions could very quickly drop below 3a with indirect sunlight....I suspect. So potentially lowering the amperage at which it "releases" to something older panels can easily output shorted. Any thoughts on this? I could be way off.
