This looks to be the mob Dottie is talking about and they do household solar
https://chriselec.com.au/solar/ fortunately, there are no door to door RV solar sales people .... yet.
This looks like a very long read, sit down with a drink of choice and read it bit at a time, it will be a real eye opener to many people.
Anyone thinking of going solar/battery/grid connect should first look at the success rate of the products offered. Many of the cheaper solar quote mobs use Chinese solar panels that don't have a great life expectancy is history is any guide. Teir 1 is great line many of these mobs roll out, but don't be fooled into thinking that means they have any sort of record relating to be being 1st quality. Best Google just what Tier 1 means if you are using that as a guide.
Next is the inverter, look up the name and model and see what list of failures pops up .... including catching fire or simply not working correctly from the day they were installed ...... then follow up how the problem was solved. The actual back up provided by the company you dealt with can often be less than excellent with the complaint just being pushed off to the manufacturer .... in China naturally .... Brcause you weren't the person who they dealt with when they filled the purchase order, you get the "lost in translation" run around till you give up ... or try the legal system solution .....
Next comes the solar battery. The B/S being pushed across South Australian TV at the moment really brings the whole advertising rules into question ..... Read through this and see what you think they are saying

I know I mentioned Tindo before, but at least they will back up what they sell, but don't be mislead into interpreting
Whether you’re watching TV, blasting the air con, charging your phone or just boiling the kettle, you’re adding to your power bill. The power that you generate during the day from your solar system can easily be stored in a battery for use during the day or at night
Into meaning, you can power the TV, blast the air con, boil the kettle ..... the only true bit out of that is you could charge your phone, so not a completely misleading I guess.
The first thing to understand is the capacity one of these batteries offers:
kWh means little to most people, but it says 1,000w energy for 1 hr. Still eyes rolling? Look at the kettle base, 2400W? Still head spinning ....
Lets break it down further to watts per minute, that might make it easier. 1,000 watt hrs x 60 = watt mins = 60,000 watt mins ....don't give up yet, 2400w means that it will require 2400 watts for as long as it is powered, in this case, boiling the water. So, 60,000 watt mins will power the kettle for 25 mins ..... so a 7kWh battery would theoretically boil the kettle for 7 x 25 mins ..... sounds a lot doesn't. The other things mentioned was the TV and blasting the air con, but being after the sun has gone down, you might want to turn the lights on and a few other things ....... start adding up each appliance, how long it is turned on and how many watts it uses, add them together and then divide that huge number, 7 x 60,000 = 420,000 mins at 1 w, or how many minutes at the number you just came up with .... if you are power conservative, maybe 1 hr if all that 7 kWh was available ..... which it isn't.
Generally they want to keep 20% in "reserve" they like to call it, so only 336,000 of those watt mins is left .... but wait, there's more ... or worse in this case.
They say they don't charge to 100% for longer battery life ...... about 95% is the best you'll see, the top end is kept for "balancing" purposes .... you need to understand a lot more about the battery chemistry to really understand what they are saying between the lines, but basically, the cell balancing system used is "limited" in just how much it can move in a given space of time, so the proper full voltage is never reached so no cell goes over voltage and is damaged ...... the same reason for 20% held in reserve .... plus the over rating of the true battery capacity .... but that's another matter.
So now you really only have a usable capacity of 75%, or in this case 315,000 watt mins or 5,250 kWh.
But, it gets worse.
To get that govt subsidy, you promise to make that 315,000 watt mins available for the grid to use when ever they need it, and peak load, that period when you are paying over 40 cents a kWh, is the most likely time they'll need it, the same time as you need it ...... bet you can't guess who gets first dibs on it, you did sign it away after all ......
There are no free lunches, the govt is not here to help you, keep this in mind when ever you see a great deal ..... the fine print says otherwise .....
