You could call and insist

Even though I have a sunsynk, they did it. I did take about 10 emails though... 

And still going in circles....

SA is worth the money. Stop begging them the access. I dont f'king understand why wouldn't they allow the end user to remotely access the settings of their inverters.
Whatever an enduser could access a setting physically, is what you get on their remote access (solarman). There is nothing special that could start a nuclear holocaust. So I dont understand the restriction.
If an end user f'kd the settings remotely, there is a higher chance they would f'k it first physically.

Hi everyone,
We have had a rough couple of days. We have been made aware that SA Solar Suppliers (sasolarsuppliers.co.za) have been using our VAT and Company Reg No. 
This is fraudulent and we have opened a case against them.
Our hardworking team is in NO WAY AFFILIATED WITH THEM and it is causing reputation all damage to our company. 
This comes after the fact that we were broken into last week and COMPLETELY cleared out. 
 
Please spread the news and if anyone has any info please contact us at the number on our website.

None. Their approach goes like "its a trade secret".

5kw inverter, 10kw battery and 14 x 455w panels

Some of their staffs now asks if there is a problem with the inverter on why one requests an update. I mean.. why is there an update in the firmware in the first place? Isn't it firmware updates usually means there is something to fix? I'd rather have that "fix" than wait for the problem to occur.

I am assuming you have solar panels as well? Generally Lithium batteries don't like being at 100% all the time - unlike Gel. It might be worth setting up a schedule to use them then recharge using the panels - basically some form of cycling for the batteries - this would also start to payback your investment in the system by reducing reliance on Eskom

Hey guys, 
Just had my 5kw updated, looks like theres a new MCU version out, moved from 3.3.7.4 to 3.3.8.0

Also a great month in Pretoria
 

Also biggest month for me in 9 months.

All you will get here are rumours. Wait until your municipality submits their application to NERSA and then you can evaluate from there. 

OK... Try to get that down. I use about 13 to 15 kw/h a day. I was averaging 13 before we switched to solar.
If I define a "night" as "the time I don't have much useful PV" then that comes to about 16:00 to about 7:00 right now. I would usually use 40% of that that 10kw/h battery over that time, with a setup similar to yours (LED lights, 3 fridges, LED TV, electric fence, alarm, phones charging). So in my scenario a 5kw/h battery is going to get pushed to the edge of it's usefulness overnight, and if we had load shedding early in the morning then we might run into problems. At 7am (at the moment) our heat pump kicks in. By about 7:45 I'm getting some useful PV, but still less than the heatpump is drawing.

This morning we got down to 51% SOC at 8:40. A 5kw/h battery would now be useless for powering the house. If load shedding had started at 8, we'd have had problems for a while until PV came back on line. 

NB! We have a gas hob and oven, and we have a rule that we don't use an electric kettle between 16:00 and 8:00. 

So I think you will have to give up something here. Either set a reasonable reserve on the battery (enough to get the essential circuits through a 2.5 hour load shed) and use some municipal juice during the night, or try to get through the night and hope that there are no outages in the early morning.

You can leave the geyser and oven on non-essential. They will get no power when grid goes down, but if there is grid, and your geyser kicks in at (for eg) 06:00, it is going to have to draw from battery or grid (probably battery at first). You will need matches or something else to light your gas stove.
[EDIT] You should be saving money though. You have more PV panel power than I do, and on a good day I use a fraction of a kw/h.
