FWIW as a comparison. My batteries (2x 5.1kwh SS) coupled with 8kw SS are currently on 100% (I had disabled timer last night, rainy day forecast in cape town).

Caveat: I don't know much about this inverter except that it's a 3-phase. It's a 12kw inverter (not kwh) which relates to the maximum power at any one point in time. Production "in a day" has the time element to it, so that would be kwh, and would / can be a multiple of that. It can accept around 15kw PV across its two MPPT inputs, so under ideal conditions and with enough panels you can produce a lot of solar in a day. edit: posted concurrently

It was certainly R500 less last night still, now gone up to R2760. Trust the price was correct at the time, albeit PFS quotes prices on request, it's not an online purchase at a displayed price.

Clips are required for the battery - becomes pretty self-explanatory connecting the DC cable to them (the gland offers a tighter fit - insert the cable into the metal hole, and then screw the plastic lid at back over it all (bit like shrink sleeve, place cable through it first). I had to slightly reduce the size of my 35mm cable to make it fit. Then it just clips into the battery. Think it's called an ESS connector. Comms cable to battery comes with the inverter, IIRC. Pretty sure they're dead easy to make up yourself with a lan cable crimper, the required 'pin' schematic is on the site somewhere.

Great outcome, well done all. How do you manage to have such a low house load though ☺️

Interesting, so after the breaker (load being removed), it's quite safe to wriggle out the PV fuse(s) if needed, and replace it again, on a sunny day. I haven't, but was just curious, as above seemed counter-intuitive to me. Thanks!

Out of interest, if the breakers are downstream of fuses as suggested above, how would one remove or change a PV fuse during a sunny day (bearing in mind house loads and incoming DC current/voltage from the strings)?

Thanks Talia. Are you suggesting that the Eaton Bussman and Jean Müller fuselinks commonly sold with the disconnectors are not appropriate for use between inverter and battery? They're rated gG/gL but not gS...

Sorry for butting in here. What you say makes sense; however my SS inverter setting is priority battery and when I have PV available, the house loads get fed first, and any surplus PV charges the batteries, not vice versa with battery first etc. This is obviously the way I want it. In similar scenario, if I’m already at my preset minimum SOC, with grid present, then PV goes to house loads first, but if there’s insufficient PV it draws the shortfall from the grid. No battery recharge prioritization over load/house ever. Does this make sense? In terms of limiting grid usage per the OP, the two most critical things for me were to shift loads to a little later in day and try to stagger (and have a sufficiently low SOC setting for daytime to accommodate the swings of power usage), and having the „limit to house“ setting permanently enabled (with a bit of battery SOC setting intervention) so that non-essentials benefit from the sun during the day. All assuming CT coil etc are correct obviously.

Possibly. I set up my SunSynk dongle / wifi pairing / account myself, with full „privileges“ (I think installer level), as I wanted it that way. Glad to hear that you found a solution to upgrade and that you now have 60s sync. Good looking install by the way, and nice to see you’ve got individual DC connectors/fuse links for each battery. I also went that route, and in fact, my two batteries go to a common busbar after the DC disconnectors, and then onward to inverter (one inverter).

Mine is set to 20W. I thought it was mainly for frequency synchronisation, but not sure. Check my post here:

You can set the synchronisation updates to 60 seconds (via sunsynk.net login). Less sore thumbs on the app refresh!

I recently retrofitted the wifi geyserwise (one needed a drop-in PCB, and the other one a new display) to my two geysers. 5 minute jobs. Previously had the standard TSE1 and Delta models. PlumbIt online had great service and best prices amongst all (or so it seems). Geyserwise now runs via Tuya app and is great for remote enabling as PV dumps. If your existing geyserwise has a three digit temperature display (i.e. three digits showing even though temp shows without decimals) then the PCB retrofit works, else you need a new screen (a few hundred rand more). Is the Geyserwala basically a geyserwise "copy" / third party product with additional functionality?

That's a lot yes, others can comment about replacing the element with something smaller. Mine are 2kw and 3kw respectively, and one really notices the impact on the 3kw unit when used in combination with a few other power users (8kw inverter/ 10kwh battery setup). When there's 3-5kw winter PV available - haven't experienced summer yet - it's obviously ok.

You can reduce the refresh rate to 60 seconds (default is 5 minutes, I think). So it seems - thanks for the P-External-CT-L1 headsup, i hadn't added that as my preferred charting metrics and nice that it's included there at least (I'd still prefer it on the main display). I was doing same - and have since kept things on the "limit to home", so all data shows on main display, and while grid is present any load beyond the 8kw inverter rating just gets drawn from grid. As mentioned earlier, I now have a slightly more conservative battery regime, and/or am timing geyser use in an early morning time bracket where de facto it will take from grid, as I've hit the minimum SOC already (or am close to it). I've just retrofitted my two geyserwise displays with the tuya wifi option (one needed a new display plus power box, while the other just needed the PCB), and can now add them into the mix remotely via app when there's excess PV and I need to dump / utilise free energy that would otherwise go to waste. I've also set timers to a slot where there's most likely to be excess PV available. Yes there are ways to automate this, but my setup is actually quite simple. Since both are solar geysers, in the summer months it will mostly be moot, as the geyers will be hot enough and hardly be able to be used as excess PV energy dumps.
