Glad to help. My units were very much the first edition I purchased from Hubble. 
If they have stuck to the recipe then they are absolute beasts! No problems nothing funny happening. 
They just work.
Sincerely

Still working perfectly.

Many points have been covered. Just ensure you choose inverter aircons for their reduced and kinder starting power when on battery power. Also they use less during running. 
It might assist to get a Kill-o-watt meter so that you can for instance measure what power items like aircon, washing machine per cycle and fridges are using per 24h.
Try and record the actual readings and keep a log of them. This way you can build up info of time of use and be helpful. It is really the after sunset kWh per day that is important to guesstimate battery requirements. 

Thanks for the replies.
So at our current place, my statement is showing usage at 34kwh/day. But here we are still on an electric stove and use it a few times a day to prep kids meals etc. Then its the washing machine probably 6-8 times a week.
3 aircons in this place, 2x18000btu and 1x12000btu. 2 of the 3 get used for probably 12 hours a day total in summer.
Day useage is high, at night its just 1 AC in summer.
So its difficult to guess what it will be at the new place, but we are willing to change and adapt to the system like using the high draw appliances during peak hours only, skipping washing on cloudy days etc. The heat pump and pool pumps can be on a timer to be used only during peak sunlight hours.
So yes, we are open to change our way of living.

Given your requirements, I'd much rather go with either 3x10kwh or 2x15.97kwh batteries - Sunsynk or Freedom Won. They are of course massive items but it's so much better with regards to installation of cables and communications. Freedom won actually recommends going with the larger batteries instead of multiple smaller ones. Price wise it might also be cheaper I think. Just my 2-pence.
EDIT: The Pylons are just plain Lithium Ion whereas the sunsynk and freedom wons are LiFePo4 technology batteries. I choose the latter for safety reasons. YMMV.

It's difficult because when we start we don't know much. I wish I knew then what I do know now. But still, you can try to find out about the installers. Ask around, ask for references, ask for recommendations.

There will always be somebody who can do the job cheaper, but often that involves cutting corners. So ask about protection. Will they include surge protectors to protect the inverter? Will there be protection against lightning strikes? It's not small change you are spending, so spending a bit more to have it done properly makes sense. 

Also ask them about the location of the panels. Some new systems have gone up in my neighbourhood with south facing panels. I would bet that those guys are not enjoying the full benefits of solar power.

Try to get an idea of the after sales service they provide and how long they've been doing this. My installer was doing this pre lockdown, kept on going through the lockdown, and 3.5 years after installation still gave me support. Not for free, but still helped me out. So that's worth something too.

Hi All.
I am currently building a new home and about 3 months away from moving in. I am looking to invest in a good system upfront and have this installed before moving in.
I have been in discussions with a few companies in Durban, but I feel the advise from them is not all that great.
The house will be a 450sqm, 4 bed, with a pool, home office and gym. Gas stove, heat pump for geyser and a heat pump for the pool. Aircons in all rooms.
We are a small family, 3 of the rooms will be used, and not more than 3 aircons will be used at the same time.
 
What would be the ideal system for this.
I was given the below as a guideline. I am just wondering if this is maybe an overkill ?
I was told that if we use the batteries everynight to run the house, on days with low sunlight we will use alot of Eskom to top up the batteries and thats going to cost us alot more in the long run.
I would really appreciate some input as this is quite a large investment and I need to be sure its done correctly.
 
2x8kw inverters, Deye or Sunsynk
26x500w black panels, has to be black due to estate rules.
