October 4, 20223 yr Good Day All , I need some help from someone currently running a SNA5000 or that knows the configs. I am Trying to run my SNA5000 as a "UPS" for now until I can manage to install PV Panels, So Charge VIA AC(Eskom) , and run from Battery only during LoadShedding , At the moment , i have no Load connected to it and it charges to only 99% before discharging for a few minutes and the charging again , in a loop. Ideally i'd like it to fully charge and then bypass from grid to load and only use battery's when the Grid Fails . Below Picture for reference only , shared by another forum member but mine is doing the same. I have browsed the forums and managed to find a few threads regarding the SNA5000 , however I'm still running into some issues , so i know I've got something incorrectly configured . Some of the Threads i have found , but no real answers . I have changed the below settings as suggested on one of the Threads , My SNA is Connected to a single Dyness B3 , The comms between the two from what i can see , seems to working , No Errors being reported , I'm able to see SOC and battery details on the inverter side and on the Web interface, I'm not Able to do firmware update as i only have an EndUser account for the Luxpower Website, But i do see your able to do manual Firmware VIA the Mobile App, However there is a few firmware options available on there and sure which is applicable to the SNA Any Help here would be much appreciated .
October 4, 20223 yr Author All the Settings on my side from Luxpower remote management portal. Firmware available from App -
October 4, 20223 yr Author Current After LoadShedding Battery is on 93% and not being charged , been the same since 10:00 until now 13:44, So it's not dropping or adding to the capacity
October 4, 20223 yr Running into the same issue this side. My current setup: Luxpower Inverter Hubble Lithium x101 battery Using the CAN cable I had to manually set the battery settings on the Inverter and not use the comms between the battery/inverter. In order, to get it to work. PS: I am new to Solar! so still learning. Edited October 4, 20223 yr by JpRoux

October 4, 20223 yr Author Ok , Seems to be working , i had a round of load shedding in-between as well , Drop me a DM with your details , I'll walk you through the settings ,
October 5, 20223 yr Author Ok so i thought id add this on here as a few people asked , Note that this seems to be working for me , your milage may vary , If you do make the changes , please let me know how it's working for you and if you pick up any inconsistencies, Do note , I've only had my inverter since 28 September 2022 , So I'm still very new to this , and running the system with the "New configuration\Settings" since yesterday only. My Setup is as follows , 1 X LuxPower SNA5000WPV 1 X Dyness B3 1 X Can\Comms Cable a Screengrab from my interface this morning , 5 Min Later It Looks like it doesn't dip below 100% on the SOC from what i can see, Whether this bad for the battery i am unsure , Hopefully someone on this Forum can comment , As for the settings , the SOC and Voltage based charging does work , On SOC however it will only start charging once your battery dips below 90% (Available) , "-10%(Used)" , and will charge back up to whatever you set it to , My issue with this however is , you wont always have 100% battery available , again , not sure if having 100% available all the time is good, bad or doesn't matter. The Settings i use is as follows . Please keep me posted on how it works out for you , Or if there is someone out there with better ideas \ suggestions \ settings \ advice ,
October 5, 20223 yr @Burtthanks for the heads-up. Mine is already set with the above. However, only charges until 86%

Can is still connected, I see whichever option you chose , According to Time According to Battery According to SOC Will disable to other options , Eg. If you select According to Time it will disable the Battery \ SOC options If you select According to Battery , The Battery options become available , So from what i can gather , It will ignore the other option based on what you select , So even if the CAN Cable is connected , it should go on voltage and not SOC . Unless im wrong .
October 5, 20223 yr Author So every now and then it does go into "Bypass" but Very seldom , So you can see the BATT is full @ 100% and then it kick over to Grid only , But then a few minutes Later . It Starts Discharging from the battery again . Take a look at the Battery Voltage ,
October 5, 20223 yr Author I have 2 manuals , They are too big to upload here , but according to man , and on the other manual
October 5, 20223 yr 10 hours ago, Burt said: and now it's kicking into Full Charge mode , Nice work! I had to do manual settings. The cable scenario is only allowing the battery to charge to maximum of 88% im waiting to see what LuxPower support can assist with.

The cable scenario is only allowing the battery to charge to maximum of 88% im waiting to see what LuxPower support can assist with. The charging portion is fine.. Whats bothering me is the fact that once fully charged it immediately starts draining from the battery again . So it starts blending battery and grid . From my understanding it should not do this . Once the battery is fully charged its suppose to go into "Bypass" and only use grid .. then once eskom fails (Load Shedding) only then should it star using battery .. If you have a look at the older posts youll see . The battery is constantly being charged and discharged which doesnt seem right. If your system is charging to only 88% im assuming you have it set to either volatge or soc ? . Mine did the same untill i changed it to time based charging. SOC setting only starts charging the battery once it has dicharged to about 90%. If you want i can take a look at the settings with you . But it almost seems like the system is ignoring the "On Grid EOD settings"
October 6, 20223 yr Greeting. I am new to the forum. Also having the same problem. Battery will not maintain voltage after charge
October 6, 20223 yr Author It's Also a pity that we don't have access to all the settings via the Web Management portal . Seems like only Installers have access to manage these settings

October 17, 20223 yr Thanks Gents, I'm struggling with the same....charges and discharges even if Grid is available. Will try out the time settings without SOC. This is my current setup with SOC
