Hello MarconiRe: Program 13 page 19 'Setting voltage point back to battery mode when selecting “SBU” (SBU priority)' in program 01' of the manual reference in my #77 - what voltage do you have set as the threshold for point back?
I have the voltage set to the default value of 54v I believe. I have been reluctant to alter too many things until I figure out their effect on the other settings and to be honest I have found the manual a bit hard work with the descriptions of some of the settings. I have noticed on other comments on this forum that Axpert call something one thing and then someone else says it is actually this or that or is described as a different parameter
I managed to get the inverter working yesterday while we had a bit of sun with the pv and a load out to a kettle. The kettle was only a 1 Kw but it allowed it to take some power from the batteries as well as the PV and then when the kettle had finished the pv added power to charge the batteries alone This is the first time for some time that the pv has put this much charge into the inverter and has over the period it was working 20 mins approx. charged the batteries to 100% albeit I got a number of f12 faults. The first occurred when I was getting 6.4 amps from the pv and after it occurred it re set and carried on charging. Once the batteries were fully charged and I had had a few more f12 faults I had to go out so I shut it all off.
I did video it, albeit the whole 20 minutes but I am trying to find a way that I could add it as an attachment that was not the 2 Gb it currently is.
I suppose it is some kind of progress to get the pv charging the batteries although the issue of the f12 fault seems to then stop any charging when it occurs. I am going to try to draw off more from the batteries over the coming week and see if when they are at 50% or so the pv will re charge them even with the f12 fault occurring.
Regards the noise from the inverter, it is not so much a tonal whine as such but more like the noise of an electrical connection being made, like a buzzing sound but it may be some part on the inverter kicking in to do a specific thing it just struck me as an odd sort of noise but it may be normal.
As ever I am grateful for the help and assistance
Regards
Tonyboy
