I have a Deye 5KW hybrid inverter, it came with a wifi data stick in the box. I connect to it via the solarman.cn web interface. Currently it writes a line every 10 min or so, Is there a way to reduce the frequency of these? Alternatively what other tools are available to me to review this date. Currently I dump it all into Excel and load it into a home made PowerBI dashboard.... any help would be awesome.

Thank you.

Thank you Coulomb, super helpful. I almost never top out over 3k Load. I had actually sized my system for a 3K inverter, and only once the install was complete did the installer notice it was a 5k unit. The batteries are under 5 years old. and have not been through many cycles. I keep it ready for the inevitable power outages, rather than to drive value out of the solar set up. If i have the premature float bug, how can that be dealt with, other than through a firmware update? Thanks for all the help.

Hi all. I hope someone can help me understand a weird occurrence last night. My Set up. I have a Kodak 5kw hybrid inverter 48v input it is being fed by 4 12v 120 ah gel batteries. When the power went out. in very short order the display on the unit read a very low battery (18%) and shut down. My load was around 230w during the period and the whole set up should have been able to manage a 4 or 5 hour run time, not the 2 hours I got. When all came back online, the watch power app told me I had a EEPROM fault. I have seen else where in the forums that changing settings (to force a re-write to the memory) or flashing the firmware might help this, but the files are no longer available. In looking at the log data this morning I see two oddities. the first section has data that I have not been able to decipher, but I see a number of 1's cropping up at the time the fault occured. The second section I can read, and what is interesting to me is the variability of the battery voltage reading (Second last column). It is all over the place, telling me that there is some issue there. Can anyone provide additional input? 53005535.TXT

Thank you so much....

Thank you. Just to make sure I understand, 0.2 (for me) means I should not be drawing more than around 550w at any one point. This is independent of the time period it is drawn over. This relates to the out (or in) flow of electricity from the battery, not how long it can sustain this output. So to keep my battery in the best nick possible I should avoid stressing it by trying to draw too much from it at any one point...

Thanks for the input guys, But please can you decode 0.2C? this is a new suffix. I initially thought is was Coulomb (the measure, not the man ) But then I saw another definition that talks about Capacity/Hour. So I am a little confused. Does the size of the load (mine is pretty paltry) impact this number?

Thank you for the input. The Inverter was an error. I ordered a 3Kw, but only realised that a 5kw had been sent once installation was done. So now I have a massive Inverter. What I am kicking myself for is not swallowing the cost and taking on a Goodwe or similar that offer much better management of what gets power when the utility supply drops away. Thanks again.

Hi Coulomb, thank you for the settings I have put them into play. One question, the above statement, can you elaborate? is this due to the 'overhead' of running the inverter itself?

Thank you Coulomb, extremely helpful. I will take a close look when I am perched in front of the device and can rework the numbers. Your help is way above and beyond.

Hi All. I have read this thread and a few others on PF that relate to inverter settings. I have done my best to bring myself up to speed and the basics, but I do have a few questions to ask. First the back story and equipment details. My install is around 2 months old. My reason for posting is to confirm some of the settings that the installer put in place. I have 4x 120ah AGM/Gel hybrid Omnipower batteries in Parallel 6*335 JA solar Pv panels wired in series a Kodak 5Kw Off grid inverter VMIII (OG 5.48) My aim at the moment is to run my Study and internet during loadshedding. so the set up is to prioritise keeping the batteries at full charge in case of planned or unplanned outages. My settings are (The values I am hoping for help on are in red) 1 - SuB 2 - 20A 3 - UPS 5 - Use 6 - LTD 7 - TTD 9 - 50Hz 10 - 230 11 - Uti 20A 12 - 46v 13 - 54v 16 - SWU 18 - BOF 19 - TEP 20 - LOF 22 - AOF 23 - BYD 25 - FEN 26 - 28.4 27 - 54 29 - 45.8 30 - EDS 31 - 58.4 33 - 60 34 - 120 35 - 30d 36 - ADS 37 - NTT My questions are I aim to be as conservative as I can, my system is way overspecced for my current needs, so I can tend towards lower DoD - say 40% or better i.e. 60% remaining) For program 12 It is set to the default 46v. I have also selected SUB in Program 1 so not sure if this is even relevant. My question is, I have seen settings recommended up to 49v, what is the impact of changing this, and how does it impact DoD Program 26 The installer seems to have set the bulk charging rate WAY to low (28.4v) If I look at the spec sheet for my battery the Cycle (bulk) charge voltage should be between 14.4 - 14.7 I assume a value of 57.6 is the lowest this should be (14.4v*4 batteries). Is this a good value and does setting this higher/lower impact battery life? Program 27 The default value is 54, I have seen 56 recommended. the spec sheet says floating charge should be between 13.6v and 13.8v would 54.4 - 55.2v make more sense, and what is the impact of a higher setting on battery life program 29 This one has caused me the most confusion. As I understand it, this is essentially where you control DoD (having read that these inverters are pretty useless at calculating this correctly) A number of the regulars on the forum seem to point out that on the AExper (which mine is a rebadge of as i understand it) messing with this value messes with the batter % calculation. As it stands, the minute Eskom goes out my battery % immediately shows 50%. which cannot be right. To preserve battery life, I believe this value should be higher. I have seen recommendations that this is set to up to 49v. The most common recommendation is between 45 - 46v What should I set this to to preserve my battery (bearing in mind that I do not have the ability to buy a BMV or wire in any other relays or jiggery Pockery. I hope some one can shed some light. Many thanks. Lyle
