Feed your solar into the grid during day & charge on night tariff .
Your wife might be able to organise a 15Amp powerpoint at work to help out as well ??

There is software available which manages the system to secure maximum benefit for yourself.
With rebates so low for grid delivery it may be that the first priority is to fully recharge batteries, then heat water, then charge electric vehicle and only then send surplus to grid for piddling rebate, usually less than the cost of buying power from the grid, so a low priority.

Any thoughts of a cobalt shortage affecting battery production are making sea floor mining a viable proposition.

Unfortunately I doubt her work would be interested in supplying her vehicle power and the carpark isn't close to the building.

Feeding solar back into the grid makes almost nothing these days and I have an issue with 10 other houses in the street already have solar, so local voltage is high during the day and none of the installed systems push anywhere near what they are capable of back into the grid. I work with supply authorities intergrating diesel generation into the live grid so understand its limitations here. For solar to be effective here, it's either load shift to the day or store the energy for later. Happy to do either if I go down this path.

We need to sort a few things out first as we aren't sure hiw long we'll be in this house for at the moment, so not goong to tip bucketloads into a system like this if we are going to sell in the next few years.

Recharge and heat water during the day, run on batteries at night, if you need to draw do it when the cost is lowest seems to be the way to go. That's what I'm planning.
Consider a small wind generator too, mainly to benefit at night.

Homestar , since you work in this field I think you are qualified to answer this problem I have. Not too far off topic.

My E-Landy goes 80km per charge has a 3.3kw charger , For the purposes of discussion lets say it takes 8 hours to charge from flat. In reality it takes about 6 hours as I never go fully flat .

I charge from Solar , but if I was to charge from the grid @ a tariff of $0.25 kwh x 3.3 x 8 = $6.60

I saw a Redback RB4 5kva inverter generator ($1800) that weighs only 33kg the seller is adamant it will put out 3.5 kw all day long, 9+ hours infact from its 6.5L petrol tank , Dubious claim I think, Lets say it uses 6 Liters of Petrol to charge the E-Landy @ 1.50 per Liter x 6 = $9.00
Thats not bad since with a petrol Engine to do 80km The LandRover would have used at least 15L = $22.50

Does that sound about right ???

Unfortunately not - no way it will get 9 hours running at 3.5KW - closer to half that I would estimate without knowing what engine it was. Most of these style gens have a tank to run 8 hours at 50% load, so about 8 hours at 2.0KW woukd be closer to the mark - I'd guess around 4 to 4.5 hours at 3.5KW.

Sorry to burst your bubble.
