Hi one and all,

 

was sick and tired of all the loadshedding and took the plunge with solar. I am struggling to get my system to work in sbu mode. 

I have the following, 

10Kva Fivestar grid-tied 48v inverter (looks like the AXPERT/MERCER/VOLTRONIC inverters)

2 x 10kva 48v Narada lithium batteries (connected in parallel)

12 x 450w Mono panels

here is my issue: when the system was powered up it used the solar as primary source, in the evening the batteries took over but i got an alarm/fault (ok!! thought that when the sun rises and the solar starts generating power again the fault will clear, nope it didn't), then early hours of the morning when my geyser kicks in for the morning shower the utility takes over but does not fall back onto solar when the voltage/watts has increased with the panels.

here are my setting on the inverter:

Al r (00) APL

AFr (01) HI

_ (02) SBU

_ (03) CUt

ACP (04) 100%

SCP (05) 100%

CU (06) 14.2v

FLU (07) 13.5v

CoU (08) 10.5v

dtA (09) 11.6v

Atd (10) 13.5v

oU (11) 220v

CSt (12) 1 dE

oF (13) 50hz

rA (14) tE

bLC (15) Lod

bEC (16) AoF

bol (17) oN

LL (18) oN

LEL (19) oFF

bAU (20) 00

odt (21) 220

r5 (22) oFF

installer says when set it's set to SBU it should work according to that setting. BUT it does not, PLEASE, PLEASE help.

 

Regards

Mmm. Maybe it's an Infini (made by Voltronic) or clone thereof.

I don't recognise most of the settings. I'm concerned that many settings seem to relate to a 12 V nominal system voltage, but you seem to be using it at 48 V, and surely a 10 kW inverter would be at least 48 V nominal.

i have attached pictures of my inverter.

That doesn't look like any model I know of, sorry. Googling VR10048MFL doesn't seem to turn up anything either.

Did you come right with the settings? I have a similar inverter and yes the settings are a bit odd. Try to change from sbu to ac/uitilty. If fault comes you have to switch off the inverter and restart.

 

What time of the day are your pictures? Are you batteries fully charged daily. What type of batteries do you have,

My guess is you need to adjust these settings to suit your 48V battery, they look like they are for a 12V battery setup which means it won't be charging the batteries.

i have the similar system and i am completely of the the grid..i only mage 3 to 4 percent of usage at night from those batteries..i have separate solar geezers...here are my settings...Cu..51.8,Flu..51.6 CoU..42...this will fully charge your batteries and will be good

Hi. I also have a 10 kva fivestar. The scp and acp settings is at 100% when the inverter comes from the factory. What is the meaning of these abreviations and what should they be set at? Also where will I find the DOD setting?

Hi,

 

I am also having some trouble with this inverter as the settings aren't even remotely close to the user manual that came with it.

My client is constantly having issues and not knowing what some of the settings even mean really don't help.

does anyone have a updated version of the user manual as that might shed some light on the extra settings

the user manual only shows 15 settings and it states that you need to save after altering anything, thus not even close to the inverter settings that has 22 settings.

any assistance would be greatly appreciated.

Greetings change 02 to PUL this way solar use is prioritized, then baytery them as last resort the grid

Interesting that we still think about solar then battery and then grid. May you not get LS the moment you went to grid as the last resort and sit in the dark 🤔

Hi. I have also bought this five star inverter and it has the same 12v settings which will not change to 48v . Please let me know if you have found the solution to it

Something ain't right, it shouldn't even give 12V options options.

Where did you buy it? Cause I am sort of familiar with the products and haven't seen that one before, also only a single site I can pick up has it listed. Not even the Fivestar dealer has it on his catalogue.

 Hi All

Has anyone managed to get the correct settings for this inverter. I am trying to help my cousin out. He has the same inverter, as per the photos posted, connected to two CFE 5100 batteries. 

The batteries keep going into fault. I have logged into the batteries via wifi and the APP, but not picking up any error codes. 

Hoping someone has the answer to the settings.
