I will post some updates as soon as the second battery is installed.

Interesting graph. LS ended at 00:00. Grid started bringing my battery back to 60% SOC and geysers kicked on for a quick heating boost, as per my timers that were installed in the DB. LS again between 06:00 and 08:00. PV started to bring my battery up to 100% SOC. Geysers kicked on at 13:00 for their normal heating hour, again as per my timers in the DB.

Hope the second battery with help to reduce the grid usage during the night. Will also have to look at changing that midnight geyser timing.

@TheJman, I suspect you need to add the essential load draw of 394 and the battery charge draw of 738 to that non-essential draw of 4731. The grid draw should only be 20 and I am not sure why that is reading 120.

Newbi queation, please could you explain.. You're producing 6kw, your load is 4.7kw, why are you drawing 125w from eskom?

Looks like the inverter is feeing only 4.6kw of solar to load?

394w load + 4731w non-essential = 5125w
The inverter max inverting is 5000w, so the 125w grid draw is the difference to cover all ac requirements.

What I'm not entirely sure about is why the 1045w (6045-5000) isn't all going to the battery.
Maybe losses of the charge or the inverter is pulling 307w to stay powered on.
I think it's most likely the inverter power consumption because it's hitting near some of its maxes ie inverting was 100%, mppt 500w below the max. The only things not maxed out are the charging currents and the ac passthrough

The 307w is not all powering the inverter, any conversions between AC and DC, as well as changing voltages, are not 100% efficient so there are always power losses (part of the reason inverters get quite hot when running near full capacity).
 
@DawieZA nice setup. Thanks for sharing photos & configurations! As I'm typing this, the guys from Inisium Solar are busy installing my 5kw Deye setup.

Have you gone through applying for the Connection of Embedded Generation? If so, how did you go about doing it?
