I've got Infinisolar IV 5600 hybrid inverter. It uses the Solarpower app for monitoring but it is just horrible. Is there any way for me to get the usage data from the inverter so that I can do my own data manipulation in something like Excel? Or are there alternatives out there that can do a better job?

Cool thanks man. I have changed it and will monitor it. For the money you'd think these things are moerse clever

@Eurard Ok will do thanks. That is an odd number. Is there a specific reason?

Float = 53.6v Low DC Cut Off = 44v

Ok, just an update. I reached out to Hubble and got a response within minutes, very impressive. But basically what they said is that it is normal behavior and nothing to worry about. Thanks for all the comments, at least now I know it's not going to detonate

@MeepMoop Yes it is just too consistent not to be some predefined behavior. I'll continue investigating to find if there is some inverter or battery setting that is causing it.

Thanks I will try that

As in my original post - the settings are correct as per the Hubble specs. No issue there.

If I understand your question correctly @zsde , I use the User setting, i.e. I do not specify a specific battery type, so that I can override the float etc., so that is probably what you refer to as Voltage Control mode?

Will do that (was going to say tonight DUH) later today or tomorrow and see what happens. What I did do in a similar vain is to disconnect the grid and battery, switch on a whole lot of smaller stuff (don't have any high-power devices just yet) and the PV power did go up, BUT (and this I find strange) it still fluctuated with the peaks now much higher due to the extra load. The lows were definitely lower than the total load yet everything just ticked over without an issue.

Thanks @zsde, none of those sound/look familiar to me and I went through all the settings to see if there is something that might point to this but I found nothing.

Thanks @Bobster., unfortunately, I do not have a graph. I use really crap solarpower app but mostly observe this behavior by watching the display in the inverter.

Thanks @mzezman. Definitely not shade, clouds, etc. What do you mean when you say it could be due to load? The load is fairly constant but I'm going to ask a very stupid question now - does the power shown on the inverter normally show what is being used or what is generated i.e. if it reports 230v, 55W is that what is currently being used or is that what the panels are generating?

I have a Hubble Am-2 on a hybrid 5.6Kw inverter. I noticed that when the grid goes off the battery level quickly drops to 94% but thereafter it seems to have normal discharge. During the day when solar is available, the same happens but it then stays at 94%. Whenever the grid returns it charges up back to 100% fairly quickly. Is this something I need to be concerned about, is it maybe caused by a setting? The inverter settings is in line with the Hubble specs.

I had 10 x 560W panels installed in 2 strings on my 5.6kw hybrid inverter. I noticed now that the power on the PV input keeps on fluctuating resulting in the battery charge being switched between the grid and PV constantly. Why would this happen? Panel specs - 49.9v, 560W, 13A Inverter Specs - max PV open circuit v: 450V, 27A
