Hi All,
 
Just thought I would show off my system.
I haven't had much luck with installers and this is the third time this system has been installed.
The outcome is great and he wall exceeded my expectations let me know what you all think.
Originally the system was in a cupboard but a lot of people on the forum told me to pull it out and that is exactly what we did!
 
If anyone needs a good installer in Cape Town that knows Luxpower send me a message. 
 
Many thanks
Daniel 
 

On a sunny day you'll notice the difference

It's hard to know what your consumption really is. Can you quote it in units (kWh) per month or per day?

I have an SNA5000 installed at both my homes and one setup at my office with Dyness batteries.
Very happy with them they have not let me down.
At one home I have 10 panels and two SNA5000 working together an honestly I could not be happier with the systems. My only recommendation on the battery side would be to go with a 1c battery and not 0.5c batteries like I have now.

Nothing wrong with the way it was installed if the battery cables are the same length.

Lets see if they can assist. I don't think there is anything WRONG per se (happy to be corrected) - it just might over time lead to an imbalance where 1 battery works harder than another

Hi there Daniel
I have an Mecer Axpert inverter (not the same model as yours) and the same Dyness battery.  I have BMS comms to the inverter and the settings as set by the BMS comms is as follows:

To grid and back to battery has been set by me.
If you want to save yourself a lot of headaches and get some really cool stats and other stuff from your system have a look at SolarAssistant.  Paired with Home Assistant you can create plenty automation and dashboards like this:

Bob is my Robotic vacuum 🙂
Let me know if you want some more info.
 

Thanks very much @jumper & @Psy we have figured out what it is. The battries are perfectly fine. If I set the cut off to a safe 46 47 the unit sits on two bars as load shedding hits. If I adjust the cut off way lower the unit stays on all four bars. I am assuming it does this so that when the unit goes through those two bars it turns off as it hits the bottom. The Synapse unit was set to the default 21 and I am assuming like you have said that is very low? I have also just order a dyness 5kw battery now so quite excited about that. I am also glad there is no issue with the new inverter. 

Axperts use dip switch 2 with that dyness battery

Yep, it is now showing you more accurately how much of the battery you should be using if you want it to last. With LA you should only be using 20Ah out of a 100Ah battery whereas with the dyness you will be able to use 80Ah. So one dyness is technically the same storage as 16x12V 100A lead acids... now you see why the price of lithium really makes sense and why so many are running their 'cheaper' lead acids into the ground so quickly. The default settings are for maximum inverter runtime, not maximum battery life.
Enjoy the new inverter, it should be running cooler and quieter as the 48V uses half the current of the 24V inverter for the same load.

Thank you and what is the best way to do that? 

Look, to be honest I have seen people drive batteries into the ground a week after purchasing... there are ways that it could be the battery but do the test and check the currents. No point speculating and guessing, check the current draw and compare...

Thank you very much @Psy @jumper @Kalahari Meerkat I have adjusted all those settings and 15 minutes into load shedding it's jumped down a bar. I am not to worried about it but just hopping when I have a lithium battery installed it won't damage it. It worked perfectly with the Synapse unit so can't imagine the battries are bad after 4 months of low watt use. 

42=10.5V per battery a tad low, I would set it no lower than 46, which would be 11.5V per battery and if you have a multimeter handy, just check that all 4 batteries are at the same Voltage level when charged and toward the end of a loadshed...

Thank you, I have changed bulk to 57v left float to 54 and is there anything that needs to be adjusted on the equalization side or leave it all as the standard settings? I see cut off settings on this inverter was set up to 42 should I change it up to 47 or leave as is? Can you think of anything else I should adjust or just leave everything else as standard? Thanks once again @Psy& @jumper
