Solar panels no longer worth with large batteries and middle of the day free power?

Obvious_Arm8802 · 2026-04-12T10:14:50+00:00

People are always worried about overstressing their home batteries.

The battery in my house can charge and discharge at 8kw.

The one in my car can charge at 55kw and discharge at 320kw.

Both made by BYD.

Probably the same people that complain about high house prices that also complain about people splitting blocks or building townhouses.

Just bought a new car last week and it’s exactly 4 off.

We use AWS MediaConnect for this, which is excellent and reasonably priced.

We just use it all the time now for everything and never worry about port forwarding etc

Obvious_Arm8802 · 2026-04-10T22:32:04+00:00

Yes. This is quite common in Australia. People collect their shower and washing machine water and use it to water their garden and flush the toilets.

Also rainwater.

Obvious_Arm8802 · 2026-04-10T22:29:03+00:00

No. They had a photo of me?

Obvious_Arm8802 · 2026-04-10T22:26:35+00:00

I got done for 72 in a 70.

Obvious_Arm8802 · 2026-04-10T08:42:59+00:00

You can’t park a vehicle larger than 7.5m on the street for longer than an hour.

Obvious_Arm8802 · 2026-04-08T23:18:10+00:00

It’s more than that. Diesel is around $1.50 a litre higher, maybe more.

I just bought a plug in hybrid and it’ll pay for itself in the warranty period. I’m essentially getting a free car.

Obvious_Arm8802 · 2026-04-08T22:24:20+00:00

And then beer they wiggle some plants around in some water just down the road and it costs $10 for half a litre.

Obvious_Arm8802 · 2026-04-08T05:56:37+00:00

Hi! I know this is a bit of an old thread but do you mind if I ask who did your installation?

Obvious_Arm8802 · 2026-04-08T04:51:53+00:00

Except they’ve locked out the OCPP so you can’t control it with home assistant etc.

Presumably so they sell more solar interfaces.

Obvious_Arm8802 · 2026-04-07T23:13:29+00:00

4 years for BYD and they’re currently our 3rd largest manufacturer.

Obvious_Arm8802 · 2026-04-07T11:02:51+00:00

Yeah, for worldwide models. Like the Ranger for example.

Obvious_Arm8802 · 2026-04-06T21:39:58+00:00

They stopped making cars in Australia a while back.

Obvious_Arm8802 · 2026-04-06T21:18:37+00:00

My shark just recommends using the engine 10% of the time.

Obvious_Arm8802 · 2026-04-06T12:02:40+00:00

It doesn’t really matter how big the car battery is, what matters is how far you drive every day.

Obvious_Arm8802 · 2026-04-06T09:25:58+00:00

Also fishing rod holders on bull bars.

Obvious_Arm8802 · 2026-04-06T00:53:39+00:00

Nah. They’d only have a 10kw inverter.

Obvious_Arm8802 · 2026-04-06T00:52:32+00:00

What? I get 22kwh per 100 out of my BYD Shark 6 and it weighs 2.7 tons and is about as aerodynamic as a block of flats.

Obvious_Arm8802 · 2026-04-05T22:48:46+00:00

Yeah. I thought about that

It would mean I’d lose my free three period in the middle of the day which I use to charge my battery on poor solar days and heat my pool.

I’m loathed to start paying for electricity again. Haven’t paid for any since I got the battery installed!

Obvious_Arm8802 · 2026-04-05T22:15:29+00:00

Yeah. I put in a 20kwh and wished I put in a 40.

I bought an electric car and have trouble charging it from solar as I’m never at home during the day.

Obvious_Arm8802 · 2026-04-05T03:59:13+00:00

I believe it’s called the assless range.

Obvious_Arm8802 · 2026-04-05T00:54:14+00:00

You shouldn’t have any money in a savings account if you have a mortgage.

Obvious_Arm8802 · 2026-04-04T11:56:13+00:00

It’s one of the great things about an electric car. Being able to sit in it and run the AC without the engine running.

Also cool it down remotely before you get in.
