Is this a good deal?

Surely you can get them to come over and do a site inspection for a final quote? Don't buy the kit only to be told about the extra costs after, if they show some hesitancy dump them.
Very important this.

Also @Quintrix you need to satisfy yourself that they are the company that you want to deal with not only for the purchase (happy times), but also times when things go wrong. This is not a short-term investment, somewhat longer than the average life of a car, and when something stops working, or maybe even bigger drama (blue smoke) you want to be happy that they will firstly be around, and secondly be willing to listen to your tale of woe, and offer support and assistance with warranty claims. Same with the installer, reputation is everything, and installers are only as good as their last 3-4 installs. Will they be available to take telephonic queries after being paid? Will they come out to assist if / when things go wrong? How good were their previous installations? Do they have at least one contactable and verifiable client installation that is over one year old?

Seems decent enough, its the same inverter i have in one of my larger setups.

If budget can stretch, i'd look at 20KWhrs instead of 5, will likely cost 75k more though.
5kw of storage is only going to be ok for mild grid tied load shedding.

, I have a total of 4,8 kWh worth of battery storage, used essentially for my night time loads and load shedding, the batteries last through both sessions, during the longer nights in winter, I might need to top up from the grid with a kWh or so .
Batteries are quite expensive, but are easy to add on if you really feel that you need more, I would suggest start with one.

The total kWp is derived from adding the wattage of all nine panels up, i.e. 9x 540W = 4860 kWp. That means maximum production under pristine conditions (STC). What you are referring to is consumption (kWh).
Nono I am refering to the estimated daily production which seems to be over estimated.

This is based on my actual sun hours for each month per day at my location. My panels are not optimally tilted though so I'm summer it's a lot higher but very little in winter

From a 6.4 kWp array, I have managed to get 34 kWh, but that is with using all major appliances, two geysers and pool pump, sadly no spinning meter

The powers that be should really get their arse into gear and install smart meters to make use of this valuable resource. Imagine pumping steenbras during the day then come 22:00 not have loadshedding or 1 stage less, shock and horror

Yep, on most days, I don’t have washing, tumble drying, etc and probably end up wasting a good 10 to 15 kWh a day
