Quick update, my issue has been resolved. I reached out to Hubble who assisted me in updating the firmware of the battery. It's been 2 weeks and no issues since. Thanks for all the advice.

Yup, I'm going to ask him when he gets back from holiday, he mentioned to me why he couldn't remove the kitchen but I can't remember exactly what the reason was. Here is the board (he replaced the breakers for me as the originals were super old). The flat was built in the 60's, with less than 10 plugs in the whole place.

😞 unfortunately, I'm in a very old flat and there is only 1 breaker for all the plugs so I don't think the kitchen can be removed off the inverter but I will get an electrician to check it out. It's a Whirlpool fridge and only about 8 years old and I see it says 280w on the sticker (attached) so using Scorp's calculation it could max out at about 2.8kw then. Oh well, thanks for the input, looks like I'm doing some shopping.

Thanks Scorp, Last night it tripped while watching TV (TV (+-100w), Media Center PC (<100w), Router (<50w)) so the fridge must be pulling a lot of power during the start but it makes sense. So my options are: Upgrade the batteries to allow for higher peak draw, take the kitchen off the inverter or replace the fridge. 😞 Thanks guys for all the help

Thank you for the response Douw. I've done some more testing and if I unplug my fridge (about 5 years old) the issue stops happening, I've tested this over multiple load-shedding cycles. During loadshedding the only appliances connected are my desktop computer (+-500 watt under max load) or TV (100w), Router and maybe one light. Randomly when the fridge switches on it will "trip" the battery. I tested the fridge with a watt meter and it hits about 1000w when the compressor starts. Testing with a very high powered device like a toaster (1.5kw) or air fryer (2kw) will also trip it but not every time. I've adjusted the CV settings accordingly and will test over the next few days. I've also double-checked and the BMS and it is disabled (Ed5=Disabled according to the manual) Thanks, Michael

Hi all, I've recently had an inverter/battery (no solar) installed and running into an issue. While running off the battery, the battery will go into error mode randomly whenever the load seems to be more than about 1kw. The ALM light turns a solid red on the battery and switching it off and on fixes the issue until the next random trip. While connected to Eskom I don't have this issue, I can even run my kitchen appliances with no issue. Hardware: Battery: Hubble AM-4 2.75kw Inverter: AC/DC Dynamics PV18-3K (3kw) Inverter settings: Maximum charging current: 40, Maximum Utility charging current: 20, Battery Type: User defined, Bulk Charging Voltage (CV Voltage): 29, Floating charge voltage: 28, Battery stop discharging when grid is available: 23.5, Battery equalization: Ed5, Battery equalization voltage: 28.8 My electrician has been in contact with Hubble and we have tried their recommendations and nothing seems to help. I'm wondering if this is not possibly an inverter-related issue and what the best way to figure this out would be? Cheers, Michael
