well if you can afford it, get a powerwall,

Im sure Teslas would sell very well in the nicer parts of town, if they imported them locally.

So it's just because of brand power? I recall the local inverter buffs up in arms at how crap the Powerwall supposedly is when it was first announced.

It certainly out-performs a Chinese made inverter and so-called "Deep Cycle" lead-acid batteries. Have 12 batteries, two failed before the end of the second year, big split at negative terminal and huge blob of blue powder. Supplier (Communica) were useless and eventually refused to exchange them

I didn't know solar panels were as cheap as R1600 each.

I just bought one of these from Takealot:

Much better than the Ellies power trollies. It's pure sine wave, and the SPS-1000 model can have solar panels attached to it as well if you don't want to charge from mains.

Yeah they also forget the thing has a crazy warranty of 11 or 13 years and 80% power at that point.

Meanwhile they need to replace all their kit in half that time.

Is there an offering with Lithium batteries instead of deep cycle batteries?

In my testing with deep cycle batteries, they are not very efficient.
I read the Lithium are +90% efficient.

From who?

The Tesla Powerwall is exactly that. Which is why it’s so expensive.

And like I said above has an insane warranty which is really the sales driver to someone who can use their brain beyond the purchase price.

Excuse my ignorance but is 1.5KVA enough ?
The Ellies trolley is 1200 W

Ellies Power Inverter DC 1200w/2000va 24v

Mustek also do / did something similar ( not sure if still supplied ? )

Mecer Power Solutions

I have FOUR various UPS's <ouch> One -- a TESCOM failed last week and the local rep says I must get a new one as the one I have is too old -- WTF

An all in-one solution like the above would be great -- I am however thinking I need something like 3 KVA ?

What does a Tesla Powerwall cost ?

It's more than enough for my purposes. I just want something to get through load shedding for a few hours. I'm just powering my tv, laptop, adsl router, a few led lights, etc. All fairly low power consumers.
