Off-grid system prices from Solar Advice

Switching traditional incandescent light bulbs with energy-saving LEDs

Bit late with this advice, 99% of the people went over years/decade ago.

I bought myself a geyserwise solar kit, last week. My geyser will only get electricity from the sun, now. Hope this cuts big time from my pay-as-you-go electricity.
R11k for the kit, keeping my old geyser, just converting.

I have 10KW, and in deep winter, I needed more, as I use about 4KW / day, and a few days of crappy weather would put me under.

I have added another 10KW of panels, so that obviates that issue now. I will be adding more storage though.

I should reiterate - I am completely offgrid.

Have been for a good few years now.

It's so cool when you are the only one to blame when there's no electricity :laugh:

Grid-tied, so when the grid goes down, so does your home. Manual changeover to batteries gets it back, but you have to set the microwave clock and hope that you saved your work. When grid comes back, rinse and repeat. No-one wants to live like that.

Are these inverters not Online?

I had no idea grid-tied is manual, that is stupid, can it be?
 
Can I be honest with you?.... R100K is not gonna get you far.
For a decent set up you should be looking at three times that much.... at least.

If you buy an overpriced Victron and the most expensive batteries money can buy yes . . . . else i don't agree with you. You can get a pretty decent setup for between 100 and 150K.

I think you are wrong sir, this unit switches automatically.

Are you saying there is no anti-islanding?
 
Has anyone installed panels
1 string (8) East
1 string (8) West
instead of 2 strings (2x8) North?

200k and you can easily get a system with 20KWhr of Lithium and 10KW of panels. Plenty for most people.

Should give you well over 50KWhr of generation in summer. and 20KWhr in winter.

why on EARTH would you need that much electricity - there will be SO much waste....

I say this because you don't run EVERYTHING in your house all the time surely ???

I don't need that much (in summer), but i need to provision for winter, so...

Plus, solar panels are the cheapest part of the system, why not overprovision.

I currently use around 4kw / day. (Less at the moment as I'm not there).

Some older details -


I have more generation now (14kwhr of panels+-) and 10KWhr of LFP, but I will be finishing off the 2nd house at some point, and will need it. The panels and inverter are in place, and wired in, just not really necessary at the moment...

Will be adding aircon and underfloor heating + pool + heatpump, so why not have enough to support all of that.
