Taking lights and internet off the Grid (mostly)

New to this thread so forgive my stupidity.
Wouldnt that Ellies system be goos for a home to run non solar , maybe TV ans a few other things for a few hrs ?

little risky with modified sinewave. But the technolgy is getting better.
In the old days running a hifi or a tv on modified sinewave was terrible as you heard a humming sound come from the speakers. Very annoying indeed.
But I hear some brands nowdays are pretty good and you hear no humming.
I havent tested it myself

I only hear a hum when I put my lamp on then there is a hum from my speakers, otherwise I hear nothing and I'm on modified.

What's Victron? I don't have anything with or by that name.

I'm almost certain I read somewhere you said you have Victron inverters? If not, apologies, I'm probably mistaking you with someone else.

So how long can that box run for? Let's say I'd use 150w?

1200w / 150w will give your answer in hours, thus 8hrs would be 100% DoD which means that next months you have to buy new batteries.
4hrs = 50% DoD
2hrs = 25% DoD
etc

If you want the thing to power your stuff until jesus comes, get another string of batteries. That charge controller should easily be able to handle it.

Calculations are pretty simple:
The 2000 W one comes with two 12V 102 Ah batteries
At 240V, that 150W load uses 150/240 = 0.625 Amperes, but we are drawing this at 24V, so the draw at the batteries is 150/24 =6.25A(1)

The two batteries have 102 Ah worth of energy each, which means that at 6.25 draw, you have 204/6.25=32.64h(2)

Now that is assuming 100% of the batteries energy is given to your load. This is not the case in reality. According the specifications, the DC to AC conversion is about 80% efficient.
This means that in order to deliver 150W of usable power, the inverter has to draw 150/0.8=187.5W

Plugging this into (1) and (2)
204/((150/0.8)/24)=26.112 h



edit: ok, fixed it.

^ Very nice, pure sinewave, your electronics will love you :thumbsup:
Love the option of adding a solar panel as well

Nothing wrong with the Axperts. They do what they're supposed to, and what to cost to do.

I know.

That's why I ordered one, but Ari sent me a must (new version). On paper, the must looks better: https://www.mustups.com/new-arrival-80a-mppt-controller-5kva-must-power-solar-inverter/

It - together with my panels, microinverters, batteries, etc - is still lying in its box in the garage until I get money for someone to mount the panels. I'll do the wiring myself, but I want all cabling to run inside the wall. So I need someone who knows how to use a grinder because I'm scared shirtless.

It would be best to consult with a building engineer on this, as you might weaken your building if you grind into the walls. Where are you based? I do installations.

How much did everything set you back?
Who is Ari?

Can this thing be upgraded with Lithium batteries down the line? How much capacity can be added without overly straining the thing? (charge controller?)

It doesn't have a lithium charging circuit, of that I'm almost 100% sure. If you buy that, I don't see why it won't work.
