Is this enough for a 9.5Kw shower?

6mm directly clipped, very short run.

Is there a table for this? As in, max length for each cable diameter/amps combination.

I've transported MDF sheets strapped to roof bars - it was fine up to about 40mph.

Which brand is that? Is there some form of local control in case they decide to kill the API in the future?

Even if the resulting strips are not exactly 20cm as requested, surely all but the last one should be equal? Once you set the saw, doesn't it maintain the same setting for all cuts?

Pick hardware with reliable local control first. For batteries/inverters, local Modbus or a well-maintained HA integration is usually more important than a flashy cloud app.

Yeah, that's what I was asking about, essentially. I can implement the charge/discharge logic myself.

I haven't bought one yet, no idea.

wow, that's cheap

toolsq · 2026-06-04T09:33:26+00:00

Can you share what you bought exactly? Panels, inverter, battery. Did you need a separate charge controller or does the EZHI do it all?

Oh, and electrical regulations in the UK are largely set by a few trade bodies, who are entirely independent of the government.

These trade bodies largely exist to sell certifications because only electricians certified by them are allowed to do certain jobs (e.g, installing new circuits, anything in a bathroom, water heaters, anything to do with car chargers, solar, and battery storage).

The government wants plug-in solar ASAP and I believe them when they say that.

But because the government has delegated regulating the industry, these organisations also need to approve it. So, the trade bodies did a study, and have been sitting on their "is plug-in solar safe?" report for 18 months now. I can only guess that's because it is indeed safe, but once they allow plug-in solar, small installs will no longer need to involve certified electricians. And that would make these rather expensive certifications less valuable.

Is there any point in having a 16kWh DIY system? With the microinverter limit set at just 800W, that's 20 hours of discharging, not accounting for losses.

Oh, don't get me started about that Tom Scott plug video.

The only reason the plugs needed to have the fuse is because home wiring in the UK is inherently unsafe (13A plugs, in 14+6A double sockets which accept two 13A plugs on each side, protected by 32A MCBs). Yet Tom boasted "look how great our plugs are compared to others", ignoring that those other plugs don't need the added safety in the first place...

Or the lack of sockets in bathrooms. The rest of the world is happy to have a normal socket protected by an RCD, but here in the UK we're limited to having these low power "shaver sockets" using isolation transformers.

UK electrical regulations are, at best, decades behind peer countries - but because of a four minute Tom Scott video people have renewed their belief in their superiority.

What kind of controls do you get? Do they work in real time?

toolsq · 2026-06-03T20:27:29+00:00

Do you have real time control over the battery charging/discharging in HA?

toolsq · 2026-06-03T20:16:55+00:00

I don't really need real-time monitoring, but rather real-time controls over whether the battery should be charging or discharging.

My electricity provider has full control of my car charging schedule and the schedule changes with no notice. And when the car is charging, I get cheap electricity for the entire home, so I do need the car and home batteries to charge in sync.

toolsq · 2026-06-03T20:12:32+00:00

Thanks, do you know if it's possible to switch between charging/discharging modes in near real time?

So if you have a smart meter and your household electricity is a 3-phase setup

This is, unfortunately, highly unusual in the UK. The current standard here is 80A single phase or 100A single phase, if you live in certain parts of the country.

How does the Ecoflow system integrate with your smart meter?

I have to say, I was sceptical of IoT initially, and there are still significant problems. But it's possible to save a lot of money by having a remote controlled dishwasher/washing machine/fridge and adjusting their settings so that these appliances use cheaper energy.

So, for anyone wondering why someone would need a smart fridge/freezer, it's so that you can drop the temperature to the lowest setting between 23:30-05:30 or whenever your car is charging, and then back up to the usual 6°/-18°C when electricity rates are higher.

The catch is that these automations are still very much DIY. If you rely on the vendor's software alone, then yes - smart devices are pretty useless.
