Mecer Inverter Settings

TheChamp said:
I have always been surprised by what normal households look like on MyBb, on backup, 3 TVs all on at the same time during loadshedding, some animal thing that also needs to be powered, frequent kettle and microwaving, hairdryer, a massive gaming PC, 3 fridges and an aircon plus a couple of fans.

All I long I thought a backup means the bare minimum, a single TV, lights, PC, laptops, routers etc, but it looks like some people have different ideas.

Hi, What do you think my Inverter settings should be, I have six 330 panels, kw Mecer Sol-I-AX-5P inverter with a Freedom one E5000 Lifepo 4 Lithium Battery. The system works fine except if the battery shuts down during load shedding it doesn't reboot whem the Utility comes back on, I cannot fine out what the correct settings should be.

I have noted the post, will respond later.

It's not supposed to "reboot". The battery is going into protection mode to prevent you from damaging it further, because your electrical loads are drawing too much power. Try to reduce the loads that you place on the inverter and battery during load shedding.

I don't think he's getting that part.

Can you post the current settings of your inverter?

Well in fairness to gramps, it does sound a bit cryptic: "Shed your loads when there is loadshedding". Especially for a layperson whose primary reason for getting the setup was to achieve the exact opposite. :ROFL:
 
what options do you have for setting 05 on the inverter?
What are you current settings for 02, 05, 12, 13 26, 29, 27

how is the battery communicating with the inverter?

Thanks for getting back to me. The current settings are,1. SBU,/ 2. 50A,/ 3. APL,/ 4. 5d5,/ 5. USE, /6. LTE,/ 7. t?e, 9. 50A,/ 11. 60A, /12. 49v,/ 13. 51v. /16. SNU,/ 18. 60f, /19. ?ep,/ 20. LON,/ 22. AOF,/ 23. BYE,/ 25. FD5,/26. 54vCu/ 27. 54v FLu/ 28. 51G/ 29. 48v Cu/ 30. ONE/ 31. 5bd/ 32. AVE, / 33. ED5/ 34. 58.4 Eu/ 35. 60/ 36. 120/ 37. 30d/ 38. DL5 nec / 39. AD5.

There's really nothing out of the ordinary that could be causing the battery to shut down, but then we don't know the battery specs, I asked you about the battery manual earlier, do you have it? Try lifting setting 29 to a slightly higher figure and see what happens.

Something also looks odd with your bulk voltage(26), it should be higher. Also set the alarm on (18)

29 will just make it cut over to Eskom sooner and he doesn't want 18 on as it will be constantly beeping on solar

Oh, I thought it was the low battery alarm and he could check at what voltage it goes off.

He can set 29 to where it was before, no big deal, it's all for testing purposes. The problem I know with Axpert inverters is there usually is some under-reading or over-reading of the values, especially when there is no comms between battery and inverter, so the value he sees on the inverter might not necessarily be the true value of the battery voltage causing such issues.

Or maybe the battery has dome settings of it's own?
 
I have a Battery manual, it says 29, Minimum cut off 49v & 26 Max Charge Voltage 55.5. The Specs are: Total Capacity Kwh = 5, Energy 80% DoD 1=4, Energy 90% DoD 1=4.Current Capacity (Ah)=100. Max/Cont. Charge Current (A)2 = 80/70. Max Cont. Charge Power(kW)2 = 4.2/3.6. Max Cont. Discharge Current(A)2 = 100/90. Max Cont. Discharge Power(kW)2 =5.2/4.7. Max Inverter total Rated Power = 5kVA. Nominal Voltage = 52V to suit 48V inverters, min 47V, Max 56V. Is that any help? I should mention there are 6 lights on the battery ,when all on the battery is fully charged, but if it has been cloudy in the day and the battery isn't fully charged by the time the sun goes down ( maybe only 4 lights on ) after approx. 1 .5 hrs the battery shuts down. all we have had on is 1 TV, Fridge/freezer, fridge and 3/4 L.E.D. lights. But the problem is that when the utility does return the battery does not reboot and I need to do it manually. That's not a problem but if we are on holiday and that happens all the fridges and freezers etc will just thaw out.

Has it always been like that or it used to work okay previously? There is a way of mitigating your problem for when you go away, we'll get to that in a minute, I just want to understand what exactly is happening, because it seems as if the battery goes into idle and doesn't detect the power draw.
 
While we are still looking for a solution, if you are going away, set Program 1 to utility to only use solar and battery if the mains is off.

This doesn't sound right at all, a 5kWh battery is supposed to cruise through that. Maybe your battery is not getting charged properly? Set Program 26 to 55.5V as your battery indicates, up the current to 60A, and disable power saving mode in prrogram 4.
 
Do you own a multimeter? Can you get us the battery voltage when full and when nearly flat?
