*******UPDATE******* Nive from Lithium Batteries South Africa (LBSA) made contact with me on this forum and offered to look into the matter. She had the battery collected from my house. The battery then received a full service and they found a loose terminal to be the cause of the issue. My battery was returned to my house same day and is now working perfectly. I cant tell you how impressed I am with LBSA after sales service. Their excellent reviews on Google reviews back this claim up. Do yourselves a favour and check out LBSA products and support a local business with excellent products and after sales service.

Thank you all for your detailed and kind words of wisdom. The original installer is coming next week to do a full service of the system and to check for any problems that could be causing this issue. I will provide an update once he has been round. Thank you

@Kalahari Meerkat Thank for your reply. I am connected to the Grid This rapid discharge when using the kettle etc happens during sunny days and at night. Once the battery rapidly discharges itself to around 6% the grid / solar does charge it up again. It charges up to around 30% then next thing its back at 100%. I have no idea if its RS485 or CANbus I have never changed any setting on the inverter or battery apart from some TOU times and %s. This issue started a few months ago randomly and now it happens every time I use a kettle/microwave Thank you @Kalahari Meerkat Thank for your reply.

Hello Members Your assistance would be appreciated. I have a Deye 5kw inverter with a 5kw LBSA lithium battery and 6 X550w solar panels. For the past few months each time I switch on an appliance like a microwave or kettle even for less than a minute the battery drops from fully charged to around 6% instantly. This happens when there is no load shedding, very little other loads apart from a few LED lights. If not switching on an appliance like a kettle, the battery works as it should and discharges correctly as the house usually is drawing around 400w all the time. When we have outages the battery keeps going all night without any issues. The issue only arises when a kettle or microwave or hair dryer is turned on for a few moments. I have had this system for 3.5 years and only in the past few months this has started happening. Your advice would be greatly appreciated. Regards, Giulio

Hi 87 Thank you for your confirmation of settings. I will touch base if and when they decide to replace the batteries. Thank you also for spending so much time reading my posts and for all your answers, its much appreciated. GBF

Hi 87 Below are the current settings that the inverter company inputted when they installed the temporary loan Lithium battery last week. Prior I have only been running 4 X 100ah 12v batteries which cant hold the charge for more than a few seconds when load shedding starts. My settings you asked for are as follows (Version U1 72 30): 00 ESC 01 UE1 02 40A 03 APL 04 5d5 05 USE 06 LFD 07 TFD (the middle letter was a weird looking symbol that was almost an F?) 09 50Hz UE1 11 40A 12 47V 13 51v 16 SNU 18 60N 19 ESP 20 LON 22 AON 23 byd 25 Fd5 26 54.6v 27 54v 28 51G 29 45v 30 ONE 31 56E 32 AUT 33 Ed5 34 58.4v 35 60 36 120 37 30d 38 dl 5 30 Ad 5

Hi there, thank you so much for your reply. So the inverter eventually switched on again by the tie i got home from work. The batteries must have drawn down to zero and switched off the inverter. As I sit here, its been 36 hours since the inverter switched off and the Lithium battery has managed to slowly charge itself up to 75% according to the BMS on the battery. I am assuming this is far too long for a 2.4kw lithium to charge to 75% so could it be that my inverter is simply not charging up the batteries properly? When I had the 4 X 100ah batteries hooked up previously, I suspected that they were just never charging which is why the inverter kept flashing Error 04. Unfortunately the standard AGM batteries dont have their own BMS to verify their charge. The screen on the inverter would show them as fully charged within a minute of charging yet they couldnt supply power for even a couple of seconds. We may have load shedding again at 10pm tonight so I will wait and see how the replacement lithium battery reacts this time. I will note down all the settings you mention and post them here shortly. Could it be a case of a burned fuse or wire somewhere inside the inverter which caused it to weak charge the batteries exactly one year into owning it?

This is on the temporary lithium battery they put in yesterday. Inverter wont switch on at all.

Hi, it just showed a continuous red LED light. Every 30 seconds or so it makes a tick tick sound for a split second with a flashing green led light then immediately returns to just a red light.

Good morning fellow members. I am new at this so please excuse my ignorance. In November 2019 I had a Voltex 5kva 48A inverter installed with 4 X 100ah 12v Batteries. All worked well and in December 2020 it started flashing an Error 04 when there was load shedding and it would shut down in a few minutes, even when we switched off everything in the house and it was only drawing 50w. After begging the installers for 7 months to test the batteries they eventually came out and found the batteries were weak. 2 weeks ago they replaced the batteries with a brand new set of the same spec. That evening as load shedding started the exact same thing happened again flashing Error 04 and the inverter switched off and we were in darkness. Yesterday they came and placed a temporary 2.4kw lithium (50A 50ah) battery to see what happens. As soon as load shedding started the whole system switched off and we had no backup power. Now the inverter wont even switch on again. Does anybody here know what could be the cause of this? Could the inverter perhaps be not charging the batteries leading to the batteries dying instantly? I am at a loss here. Thanking you for your inputs.
