Hi. We've been having the same issue with Luxpower and Hubble. We've only been able to sort it by setting to Lead Acid and setting voltages and currents manually. BMS Cables are perfect. If anyone has a solution, please let me know. Thanks.

Hi. I've installed a Luxpower SNA 5000 Eco Hybrid Inverter with a Pylontech US2000 battery (50Ah). There are no solar panels at present. The inverter and battery are communicating fine. However the battery charges to 100% then the system switches to battery until the battery discharges to a certain level and then switches back to charging. Does anyone know what settings I should apply to keep the batteries charged so that when there is load shedding, the user has 100% capacity to work from. I also want to discharge to 10% SOC when there is no Grid AC. Note: I also set setting 14 (AC Charge settings) as follows: Start 00:00, End 23:59 for all 3 settings. I haven't set 15 (Utility Source to take load) yet. Should I apply the same as 14. Lastly, how do I get an installer code? This is the first Luxpower unit I have worked with but I can't setup the Wifi without the installer code. I would prefer to have my own Installer code.

Hi MikeP Please email me at [email protected] and give me your firmware version. I have the last 2 versions and can mail them to you.

I tried changing setting 12 on another Growatt connected to a Pylontech battery, and it changes without issue. My inverter software must have a bug. I have written to Growatt for help.

Let me understand you. I want my battery to only discharge to 80% of full capacity under normal utility conditions as it cycles between battery and mains. So are you saying that setting it at 20% means a 20% discharge? This is not setting 21 which is 20% and the point at which the inverter shuts down. Anyway I tried the 20% and it still defaults to 50%. No joy.

So as per the above photo it changes on the app, but when you go back to the inverter, setting 12 shows 50%. Try to change it on the unit and it defaults to 50%. Either there is a firmware issue on the inverter, or the setting has changes via the app, but doesn't display properly on the unit. Setting 13 changes on the inverter no problem. Since I set the above parameter to 90% on the app, the battery has not been discharging below 90%. My supplier has also been trying to resolve this with me. I'll monitor for a day or 2 and let you know. thanks for the help. IMG_3635_404x720_iPhone 4.mp4

@Buyeye. With BMS, settings 12 and 13 can’t be changed. 12 defaults to 50%. My issue is ensuring the battery has enough capacity when a mains power failure occurs. The issue with SUB us that when load exceeds PV production, only Utility supplies load, not solar as well. In SBU, battery goes through charge and discharge cycles and could be in discharge state when the grid goes down, giving me limited backup capacity.

Not sure if anyone can assist with this one. I think this topic deals with settings and firmware that could help with my problem below. I have a Growatt SPF5000ES Pro and 1 x Pylontech US3000C battery. They are connected from ACAN to BMS on the Inverter and I am using Profile 36 = L52. I also have 13 x 440W solar panels in 2 strings. The problem I have is related to setting 02 - SBU The battery continuously charges and discharges. Where I live, we are prone to a number of power outages that last several hours due to a problematic substation. Most of these outages happen between 1am and 3am and can last 8 - 10 hours. Today the power went off at 2am and it is now 6pm and the power hasn’t returned. My battery shut down at 6am. Now if my battery is in discharge state, and assuming it’s at 70% and there is a power outage at that point, then I basically have 50% of battery capacity to carry me through the power outage (70% to 20%). I would much prefer if my battery would not discharge below 90%, but using profile L52, I cannot adjust setting 12 (default 50%). Is there any way I can select 12 = 90% and 13 = 95% or 100%? If I set 02 to SUB, Then the battery remains charged, but as my load goes higher than my PV production capacity, my inverter switches all loads to Utility and I don’t get the benefit of savings from PV.
