Thanks @GreenFields. It looks like 25mm thick cable between batteries and towards the inverter. My cabling is very neat, tidy and properly done. Cable trunking between everything. Battery fuses are 125A each on positive & negative connections. For now, I've set the following: Max discharge current = 75 A Max charge current = 50 A Thanks again to all for the advice & insights.

@GreenFields and @Oom Tas - Thanks guys, really appreciate your help and insights 👍 Bitter baie dankie. 😎 Based off this screen, it is limited to 50A (Charge) and 75A (Discharge) - probably defaults. From the Deye manual, it looks like 120A maximum for the inverter. What would your recommendations be?

So...I did more searches and research, and I believe the dip switch configs are incorrect. I have followed the "solar system shutdown procedure" and switched the entire system off. Changed the dip switches correctly for Deye & Dyness for Master/Slave according to the Manual, followed the "solar system start-up procedure" and got the system up and running. Now my Li-BMS is reporting much better - Charge & Discharge current is 150A and 150A 🙌 Thank you guys 😅

Thanks @GreenFields, @JayMardern and @Oom Tas, I think you all pointed me in the right direction here. I've looked at the battery dip switches now and I've mapped them out below. Current Battery 1: 1 - down 2 - down 3 - up 4 - down Current Battery 2: 1 - down 2 - up 3 - down 4 - down Current Battery 3: 1 - down 2 - up 3 - up 4 - down By comparing this to the Dyness manual, it looks like they configured it as "Master 1, Master 2 and Master 3" for all the different inverter manufacturers 😲 Shouldn't it have been Master 1 (Deye), Slave, Slave? In other words, my settings must look like the below? Proposed Battery 1: (Master-1 for Deye inverter): 1 - down 2 - down 3 - up 4 - down Proposed Battery 2 (Slave): 1 - down 2 - down 3 - down 4 - down Proposed Battery 3(Slave): 1 - down 2 - down 3 - down 4 - down

Just took these photos - not seeing anything saying 300Ah.

Dear PowerForum users, I wanted to ask for some advice, please. I have a Deye 5kW inverter with two Dyness BX51100 5kW batteries (200Ah) running perfectly for the past year. My Deye inverter is set to 200Ah on the battery setting. My installer installed another Dyness BX5110 today, so now I have three of the exact same batteries with a total of 300Ah battery capacity. My installer said that on my Deye inverter settings the battery must not be adjusted to 300Ah, it must stay on 200Ah. He spoke to his distributor to confirm this setting. Is this best practice? Insights on this will be much appreciated.

@LudwigL - Thanks for your inputs. I've been playing around seeing the same thing. I've created some automations on Home Assistant to switch on my geyser during Sunny days, when I have more than 3kW of PV and my batteries are on 100%. I'm only pulling 600W off the Grid for my 3,2kW geyser element, but I need to replace the element soon. I should be able to run a 2kW geyser element fairly effortless 😁

Thanks @GreenFields - appreciate your 2c. I'm still learning the ropes 😅

My electrician used "cabtyre" cable for my 10 meter CT extension. Similar to speaker cable and works well. Struggled with the CT wiring and direction but figured it out eventually 😅

Hi guys, I'm very new to solar - my system was installed last week. From the word go, I bought Solar Assistant for monitoring and Home Assistant for automation via my Sonoff switches. My CT is installed correctly (thanks to these forums) measuring all electricity at my Main electricity in-feed. My 3kW geyser is connected on the non-essential loads, but I need to replace my element soon so I can run it properly off solar. When my automation kicked off tonight to switch on the geyser, the "Load percentage" on Solar Assistant went to 81%. On the screenshot below, you can see that my non-essentials is on 3267 W and my essentials is on 762 W totaling 4103 W. I am therefore scared that my inverter will trip if something else goes on and my load going over my 5kW. I ran to the inverter and saw the following on the LCD. This tells me that Solar Assistant is not reading the "Load" correctly, but I'm not sure. My inverter settings is on "Export to CT" but "Limit to Load". Question: Am I correct in saying that the CT purely measures the Grid input and that the non-essentials are not going through the inverter? Any insights will be appreciated.

@anthonyhugo - My Deye 5kW inverter was installed last week. Do you see the battery information on LCD screen for BMS? It could be issues with the CAN cables.
