Awesome, thanks!

Hi all Will appreciate thoughts on this. There are some good prices out there (Inverter Warehouse, for example) but the courier fees to get it to Cpt adds up. Any good prices in Cape Town?

I purchased locally manufactured batteries that are now giving some issues. I've all but given up being helped by the original builder / supplier (may create another posting on this). Are there anyone on this forum that can refer me to someone please?

Hi everyone Any thoughts on the question re CT coils etc in this topic?

Hi everyone. I have been using a Sunsynk 5kW for a number of years with great success. I recently completed installation of another 5kW unit and are running these in parallel. It all works very well, but I have noticed that I am feeding small amounts back to the grid. Additionally, the draw from the grid is also more than needed (as batteries are full and panels are producing, as per pic). CT coil is as it has always been, as old inverter is now the master. See pics of various random draws and feedback, settings as well as picture showing erratic grid draw and feedback. Any thoughts?

Hi I boight a Luxpower inverter for my parents. Have had issues from the start (topic for another post), but have been struggling for weeks now to get Solar Advice (where I purchased the unit - again, their lack of service is a topic for another post but safe to say BEWARE) to “unbind” the wi-fi dongle so that my installer can access it. Can anyone help with someone else I can contact. It’s really ridiculous that I paid money for this unit but yet I am being held hostage by Solar Advice

Still available?

Hi I will appreciate any recommendations as my previous installer is not getting back to me. I simply need 3/4 panels moved from East-facing to North-facing.

Thanks for the info Leshen - in my case we have done the latter (i.e. use only one of the three phases)

The way I understand it my DB board was split into it's three phases with critical loads going on one, the oven on the second and the geyser on the third (with the latter two not working when there is load shedding). The geyser is now also on the first, but on the Eskom side of the inverter. The CT clamp is then on the Eskom side of the geyser. Or something like that...

Cannot for the life of me find an edit button (only "share" or "report") so will do one by one. This was after the changed settings

So I had the installed back today to try and fit the CT clamp correctly and re-did my experiment. Full sun on panels, load 400ish W and PV the same. Switch on the geyser.... Nothing happens. Fiddle in the settings and un-tick the "Limit to Load only" box on the first picture. Redo the experiment and get the following before and after pics (for grid view and flowchart view). Does this look correct to you?

Any idea how this will have to look different when there is a three phase power supply?

Thanks all!

Thanks Brani. Any chance of posting a link, or editing the pic so that the sides are not cut off (or perhaps it’s just me?)

You said you are not using AUX port, so I understand you have critical loads connected to Load, and noting on aux. Your inverter is connected directly to the mains from Eskom? Yes where is your geyser connected? Directly to Eskom. So if Eskom goes down my geyser does not work

Thanks for the quick response Tariq. So still not on a critical load? Is this the standard way of installing these?

Hi all Just had my new inverter installed and want to confirm that my understanding is correct I have critical load circuits, and non-critical load circuits. The former are all connected to the inverter, the latter only consist of my oven and geyser. I understand that it is possible to direct excess PV power to off-set the grid draw on non-critical load circuits (like my geyser). Is this correct? So let’s say PV generates 3000W, essential circuits are drawing 2000W and batteries are full. Geyser switches on and draws 2500W - the excess 1000W of PV is used to off-set draw from the grid and as such I only use 1500W from Eskom. This can be done without pushing back to the grid, through use of the CT clamp. Note that I am also not looking to use the Aux port for this. Is my understanding correct? I have been told that the inverter is correctly set up, but did the following test: Load from the house - 700W PV generates 700W Then I switch on the tumble dryer and load goes up to 2700W, with PV going to 2200W. OK, all good. Switch off tumble dryer and load and PV drops back to 700W. Now I switch on my geyser, and the house load stays on 700W (as expected, as the geyser load does not go through the inverter). I would, however, expect the PV generation to go back up so that it off-sets some of the geyser draw. Can someone please explain the flaw in my logic?

Yup

Hi - does anyone have experience using one of these? https://www.earthwiseproducts.co.uk/solic-200/ I would like to use this to divert excess PV energy to my geyser, which will be on a non-essential circuit. In addition, I plan on using my geyser wise controller to "top-up" to a minimum temperature when there isn't enough excess PV. Any flaws in this plan?

Thanks @Tariq . Is there not a way to wire it up so that you don’t need manual intervention on cloudy days? Or did I not understand correctly?

Thanks very much for the responses. I am not familiar with the aux function, how does this work?
