Yeah no worries: 1. First one is PV watts produced 2. This is the voltage value from the PV produced 3. This is the amperage from the PV produced. Will try get a landscape view for you.

Voltage estimate SOC - still waiting for a good pay check so I can get the proper stuff on those batteries for measuring and battery balancing

So the balancing act seemed to pay of a bit, produced more solar today just by changing the geyser timer, only problem is that my batteries are not full yet. So more balancing lol

@Bobster This is what I also thought, logic would have said that instead of putting the panels on the same cable, you would rather split them into their respective MPPTs. But I guess the installer is also looking at costs, because they sell a "complete system", might have them come over and re-wire so I can monitor the performance of the different sides. To all the others, I forgot to change my timer last night on the Geyser, will change it to later in the afternoon and see how the difference is on the production and use of power.

I was thinking the same thing, it is a Hybrid system

Ok so here is a bit more info on the system installed. 1. Axpert King 5Kw - 48V - 80A MPPT Regulator 2. 8 x Narada 200ah 12V - model 12NDF200 3. 12 x Renewsys 270w panels

Sinoville - Pretoria

Thanks @Pietpower Got all the info at home, so just trying to find it out Yes using a bit of Eskom power, the batteries unfortunately don't last through the whole night at the moment and its not really for a lack of trying. We have snake cases so everyone is on heat pads during the winter.

I feel like a complete blond now, I see that as the battery is approaching full charge and the load on the house stays stable the system is pulling less power so obviously the PV load and the amp starts fluctuating. Popped onto the system now to check and it started doing its funny graph thing again even though the geyser was off about an hour ago already. So next question, I would obviously want to maximize this PV production, apart from running appliances during this time could I get another set of batteries without upgrading to much.

😂 What so when I need boiled water I can just take it out the fridge again . . .

@DeepBass9 Basically I just want to understand why there is such a huge taper off into the afternoon, but as per above I want to check if the load has anything to do with it because the battery should be fully charged.

That could explain it, I never thought of that, guess an easy way to test is change Geyser timing to the afternoon and see the effect.

Currently making use of the Axpert King 5kw, this is being used to charge the batteries and run the whole system. As for the wiring of the system, I am waiting for the guys to get back to me so I can see what i happening, short of climbing on the roof to see. Yes, Geyser comes on, but pulls max 2000 watts at a time - the load from what I can see from ICC is pulled directly from the batteries first.

Hopefully you guys could assist, been lurking in the dark for a while now and finally comfortable with asking the questions without seeming like a complete noob. I had solar installed by a local company probably about 5 months ago already, however they did not have the ICC software which i managed to install and started actually checking out the finer details of my install. I noticed that there might be a fault in the way my system is setup because every time just after 12 there is a big drop in my PV yield through the system. Because I live in a complex I did not make use of the full roof space and ended up having them install 4 of the panels on the west facing side. But those who know ICC will also know the relative graph values, so I have been watching these values and every time those 4 panels on the west start catching the sun it pulls my PV yield down as well as the Amps. I am waiting for the guys to get hold of me, but any recommendations as to what the problem could be ? My assumption is the way the panels are wired . . . .
