  • Post in thread: Convincing your Daly smart BMS to balance your battery

    Well that would be one way to solve the problem but I was trying to find a 'fix' that involves keeping my Daly while making it function more like I want it to. Not everyone has the option of simply replacing their bms. Thank you.
  • Post in thread: Growatt 5000es AC voltage detected on PV input!

    Hi, everyone. Thank you for reactivating the discussion on this topic. After posting my original question, I also posted it on a different forum. I got a very detailed answer from someone who seemed to know what he is talking about. I will copy his reply here so everyone can benefit from it...
  • Post in thread: Flooded lead acid battery life if not used

    Hi. I have a large lead acid battery bank (12 tubular deep cycle flooded lead acid 12v batteries connected as 48v system). They are fairly new (probably 75 cycles max). Then I decided to switch to lithium iron phosphate with which I'm very happy. However I don't want to get rid of my lead acid...
  • Post in thread: Growatt 5000es AC voltage detected on PV input!

    Hi. I have two growatt 5000es hybrid inverters connected in parallel. All connections are correct as per instructions: For each inverter: AC input: 230v L and N and ground Ac output: 230 v L and N and ground So ground of input and output are connected to same ground wire. PV input: 300V...
  • Post in thread: Growatt 5000es AC voltage detected on PV input!

    A quick follow up to my previous post. After posting my question, I contacted a few people who do repairs on inverters (including growatt inverters). And they all said it is normal to measure an AC voltage at the PV input of the inverter even if there is no PV connected... I don't understand...
  • Post in thread: Daly BMS balancing leads (connecting / disconnecting)

    I have recently connected a Daly bms (16s, 120amp discharge, 60 amp charge ) to my lithium iron phosphate battery bank. All is working as it should. However, I have a question. If I need to do any work on my battery bank / BMS, can I disconnect the balancing leads (the plug with 17 wires) from...
  • Post in thread: Growatt 5000es AC voltage detected on PV input!

    Hi. I already checked and there is no AC or DC current back feeding into the panels at night. Also, I just wanted to clarify something in case it wasn't clear in my original post. Both the PV+ and PV - inputs of the inverter give a reading of 230V AC compared to ground. They are both at the...
  • Post in thread: Convincing your Daly smart BMS to balance your battery

    Hi, everyone. I was so excited when I found this post because I was looking for a way to get my 16s Daly bms to balance after done charging (at zero amps). However I was very disappointed to find out that the sinowealth software does not work with the 16s Daly bms (I read this and tried it but...
  • Post in thread: Growatt 5000ES

    Hi. I bought two growatt 5000ES inverters. They both come with the wires required for parallel operation. I followed the instructions and connected them and programmed them to parallel single phase (one is a master and one is a slave). All is working fine (since yesterday). However, ever since I...
