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
