Dheven Posted May 25, 2022 Posted May 25, 2022 (edited) 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 Edited May 25, 2022 by Dheven Quote

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. Quote
Dheven Posted May 25, 2022 Author Posted May 25, 2022 Hi Coulomb, i have attached pictures of my inverter. Quote

Reuben Posted July 9, 2022 Posted July 9, 2022 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, Quote
BobrowFarm Posted July 16, 2022 Posted July 16, 2022 Good morning Dheven. I just bought a unit like yours. I'm interested to find out if you came right with yours. Quote

Terai Posted September 28, 2022 Posted September 28, 2022 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 Quote
Leom Posted November 19, 2022 Posted November 19, 2022 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? Quote
MaDMaX Posted December 4, 2022 Posted December 4, 2022 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.

PsyWulf Posted December 4, 2022 Posted December 4, 2022 Does it have USB or RS232? Might want to try connect it to a laptop and inspect the settings with WatchPower/MultiSIBControl Quote
krish naidoo Posted December 5, 2022 Posted December 5, 2022 Hi I am also having problem with the same inverter. Must program 1 be set ti inverter or USB. Program is currently on utl priority. Batteries are not charging while on inverter in program 1. Also the on off switch. What position should it be on.please help. Quote
rk88 Posted December 6, 2022 Posted December 6, 2022 After searching for hours.. this is the closest I could get to a manual for this inverter [its a FIvestar Manual for another type. Abreviations etc on the settings are the same/very similar. Hope this helps. Fivestar Manual - another type - same setttings.pdf Quote
Hamanth Posted December 16, 2022 Posted December 16, 2022 Greetings change 02 to PUL this way solar use is prioritized, then baytery them as last resort the grid Quote

May you not get LS the moment you went to grid as the last resort and sit in the dark Quote
Ramson Posted May 19, 2023 Posted May 19, 2023 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 Quote
Simbarashe Hove Posted May 27, 2023 Posted May 27, 2023 Hi? I'm desperately in need of the manual for this inverter. Based in Johannesburg south Africa. Quote
Eurard Posted May 27, 2023 Posted May 27, 2023 (edited) 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. Edited May 27, 2023 by Eurard Quote
Donzo Posted June 16, 2023 Posted June 16, 2023 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. Quote
