  • Post in thread: Replacement for Growatt 5000 ES needed ** Too many issues **

    Thank you for your comments. This is my point. There is no support for the Inverters. Ordinarily there should be some form of guidance from the manufacturer, but this is not the case here. You are left with trial and error. Like you said it is about continuous fiddling. And that gets tiring...
  • Post in thread: LiPO 48V 200ah in parallel with more than 2v Voltage difference. Growatt 5000 ES Inverter.

    Thank you all for the responses. The BMS cut off the discharge. So hopefully that was done at a safe SOC. The expectation was for the Inverters to have done that which did not happen since it was set at 42V. I will monitor the batteries for a week. Fingers crossed.
  • Post in thread: Growatt 5000 ES SNU Charge Source Priority Not Working ...

    @timselectric I think I am getting more clarity. Please look at the attached. I have 642W being pulled from PV, 509W from the Grid, Charging is using 425W and 468W being consumed. From your post it appears .... the Grid is powering consumption in Bypass mode while it is the PV ONLY charging...
  • Post in thread: Growatt 5000 ES shutting down during peak solar/PV periods (11am - 1pm)

    I am still observing. I have turned down the voltages as well. Now at 57,55, 45. https://diysolarforum.com/threads/growatt-spf-5000-es-ghost-error-code-07.52860/#post-708126 Also look here. Appears similar to my case.

    Hello all .... Would like to revisit the USE vs USR2 I have 2 Growatt 5000 ES installed in Parallel with 2 x Blue Carbon 48V 200Ah Lithium Battery Pack For Solar Home System. PVs are Mono 10 x 550W. 5 panels each in series to each Inverter. Priority is set to Solar, Utility and Battery. I...
  • Post in thread: Growatt 5000 ES SNU Charge Source Priority Not Working ...

    I am recently observing a fault with my Growatt 5000 ES charging behavior. My Charge Source Priority is set to SNU – Solar and Utility. However, over the last few weeks – Solar is restricting the power being pulled from the Utility source. Prior to this Solar and Utility would always combine...
  • Post in thread: Growatt 5000 ES SNU Charge Source Priority Not Working ...

    Thank you for your response. Do you have any documentation on this? I have had my system for over 6 months and I have certainly observed over 1000W going into the battery at the same time from BOTH PV and Grid - Concurrently. I do stand to be corrected.
  • Post in thread: LiPO 48V 200ah in parallel with more than 2v Voltage difference. Growatt 5000 ES Inverter.

    Thank you @timselectric . How long do you think this should take to balance? There is minimal load on the batteries on a day to day. They are strictly for back up. Are there other things that can be done to accelerate the balancing? Or should I just leave things as they are if there is no...

    No. I wasnt. I have always been in SUB mode.

  • Post in thread: Replacement for Growatt 5000 ES needed ** Too many issues **

    Thank you @timselectric. I could most certainly use any help I can. Thank you for offering. Please let me know how to get in touch and a good time. I am currently in Barcelona but will return home over the weekend.
  • Post in thread: Replacement for Growatt 5000 ES needed ** Too many issues **

    The other point on the overcharging is that this happens only when the PV is charging. I shut down the Grid source before leaving home this week. So this tells me the Charge controller is not working right. Only option to further explore is to calibrate the Voltage reading between the Batteries...

  • Post in thread: Replacement for Growatt 5000 ES needed ** Too many issues **

    Not sure how to verify the battery cell readings. However I also notice a 1.5V difference in the Voltage reading on the Batteries vs what is showing up on Inverters. Inverters are reading higher voltage than the batteries. So, can this be calibrated or adjusted ? So when the Inverter is reading...
  • Post in thread: Growatt 5000ES - Cant set Low DC cut-off voltage

    Dear all, My Low DC cut-off voltage is resetting and allowing only 42 V. This is a new situation. So not sure what is going on. The settings for the key parameters are: 1 Output source priority: To configure load power source priority– SUB 2 Maximum charging current: – 80A 5 Battery type – USE...
  • Post in thread: Blue Carbon lifepo4 batteries

    Hello ... I have 2 of these batteries. 48V 200ah. With Growatt 5000 ES Inverters. Please kindly advise on how you set up the Bulk and Float Charging Values. The Inverter Voltage is also out of synch with the Batteries. Inverter shows 75% SOC while the battery is at 54.4 V which should be 100%...

    Thank you for the comments. I have noted the comments re. 30A. I have the Technician coming in tomorrow. However, I have attached 2 pictures. One for the Wiring from the Batteries and one for the Wiring from the Grid and the Internal distribution board. Please do note ... this issue only occurs...
  • Post in thread: Replacement for Growatt 5000 ES needed ** Too many issues **

    I am off grid i.e. I am not sending power to the Grid. But I get power from the Grid and PV. My issue has also involved the installation. I have slowly worked my way past the installation issues (breakers, wire gauge and so on). The persistent issue now is that the Growatt continuously...
  • Post in thread: Help with Growatt Maximum Ac Charge Current. Low Voltage output doing Bulk Charge from Utility.

    Replying further Battery to Inverter Run is less than 6 Meters. Inverters are at most 2 Meters from the Distribution Board. You may have a point on the Grid Voltage. I have attached additional pictures.

    Hi Radurus... I'm in interested in your set up. Please kindly provide links and or guidelines. I've been using Shinephone but would like to set up the alerts via Solar assistant.
  • Post in thread: Blue Carbon lifepo4 batteries

    Thank you @benjieg. You are correct %SOC from the Inverter is hit and miss. Goes from 100% to 75% back to 100% within 30 mins with no Load !. Do you happen to have a Voltage to SOC or % Capacity Table for this Battery. Re. 55.2 for Bulk ... the Battery Specs allows Standard Charging voltage...
  • Post in thread: Growatt SPF 5000 ES Implementation

    Hello @Alooma .. Something to note. As long as you have PV you cant charge from Grid. The only way to accelerate charging from the Grid is to turn off the PV. Even though the setting is SNU. It's not Solar and Utility at the same time. @timselectric explained this quite well in one of my...
  • Post in thread: How to read Growatt 5000ES Firmware Version

    Hello Friends, I am trying to confirm my Growatt FW version. But the numbers I am getting are very different from what is posted online. Please assist. Is there a different way to get the FW?? Please confirm.
  • Post in thread: How to read Growatt 5000ES Firmware Version

    @timselectric Thank you. That FW came with the Inverter and that was installed about 9 months ago. The latest FW as posted by others in the last few months is 41++ or in that range. Something doesn't seem right.
  • Post in thread: 2 Growatt 5000 ES in parallel. One is charging the other from the same battery!

    I have 2 x Growatt ES Inverters as well. The Growatt apps - Mobile and Web show the Batteries jumping from 75% - 100% - 75% within 15 mins with no load on the batteries. Please share guidelines on calibrating Growatt Readings with Batteries' Voltage. Thank you.
  • Post in thread: Help with Growatt Maximum Ac Charge Current. Low Voltage output doing Bulk Charge from Utility.

    Wow. I thought it was too low. Setting 11 - Maximum Utility Charging Current is set to 30A (Range is 0 - 80A) OK. Will try this out. But please explain why this could help. Sorry. Newbie.
  • Post in thread: Growatt Shinephone - Changing Inverter Settings/Parameters SPF 5000 ES

Is it OK to just update the settings and the inverter...
  • Post in thread: Growatt 5000ES - Cant set Low DC cut-off voltage

    @ @timselectric thank you again. Yes. It worked ! I set 12 to 48 and it accepted 46V for 21. I didnt think it was relevant to the other parameters. Do I need to adjust 13?
