@CallumWK these switches are sooo cheap, particularly if you just buy the actual switch element itself, that it really isn't worth your time messing about.
-
To be honest with the level of knowledge they're showing, by far the best course of action for our OP would be to continue his replacement of like for like.

The ratings on these switches are just the maximum voltage the switch contacts can handle, therefore makes no difference if low voltage AC or DC
Unless it's a hall-effect switch, in which case AC will kill it.

Partly correct.
I just measured, and when put meter on AC I measure ~8V, when put meter on DC I measure ~5V. I measure at the PCB contacts
So how I know if it is AC or DC, as I think that will matter. Not?
What happens if you measure a 9V battery with the meter set to "AC". Some (mainly cheap) meters will measure "something" if set incorrectly, I suspect your 5V DC is actually what you have.

OK so now we know it's an issue on mobile.

Go for one of the known brands, Panasonic, Schneider/Square-D etc. and you should be good to go.
We bought everything Panasonic initially, but over the years Haco and Chang have crept into the mix mainly due to the configuration we needed being in-stock.
By the way, a cooktop/hob should have a dedicated circuit unless it's just for the igniter on a gas one.

We’re about 15 minutes out from landing.
The Pilot tells us to look down and that we are passing over the co-pilots house. the copilot was happy to be coming home and to see his wife and kids.
If we looked carefully, we could see the house and amazingly enough the blue van in the driveway.
A minute or so passes and the Pilot comes back on, “I am told he does NOT have a blue van.”

I'm in two minds here.
The gallant-knight in shining armour on a big white charger (pun intended) in me would immediately gallop to her assistance.
The sceptic in me says "honey trap", get me out of my vehicle then bop!!
In a temple parking with lots of people about the knight wins hands down, on a dark country road ...
This is what Roadside-Assistance is for.

I don't think any of the digital meters have that but they have a button to switch between display mode, they can display P and Q in both directions.
Depending upon the installed firmware and settings the meters can monitor and record many parameters.
Common settings would include: -
- Import and Export energy
- Time of Use (on/off peak) usage
Pressing the blue(?) button switches between at least two display modes.

For information, this is the latest list of PEA approved inverters.
It's good to see an increasing number of hybrids being approved including my intended Deye 5kW units.

How do you know they (PEA) are monitoring his solar output?
The solar output is effectively isolated from the AC side of the inverter by loads of electronic components.
Sound like a silly story to me.
If he's grid-tied and exporting the meter is quite capable of recording the energy exported.
There have been other reports of the second meter channel recording solar export by default, and even a couple of reports of customers being billed for that exported energy!

A few members have in the past commented that there are no real consequences if you get caught for having a grid tied solar system which has not been approved and your system spins the old style meter backwards. If I recall correctly those members advised that at worst the PEA will just change the spinning meter for a new electronic one so that you can’t spin the meter backwards in future and that they never take any action against that solar system owner.
Thanks for this, this is the first report we've had of actual serious consequences from spinning the meter backwards.
I'm not sure about the legality of the PEA actually damaging private property but the home owner permitted it so ...
I would certainly not recommend the owners of large systems relying upon simply not getting caught which is the main reason we are in the process of upgrading to hybrid inverters with energy storage, if it were grid-tie our system would be well outside the allowable system parameters.
I suspect he's well above the 5kWp permitted for single-phase grid tie, maybe that's what upset PEA, looks like two arrays of 18 panels each.
By the way, it's not exactly difficult to replace those cut off cables and bring the array back into service. He would need a new hybrid inverter and energy storage of course.

you need a license/permission to export to the grid
it can be dangerous to export to grid when not supposed toIt is important to understand the difference between exporting to a live grid (no hazard) and back-feeding a dead grid (hazard to linemen).
All domestic-level grid-tie inverters implement anti-islanding which will kill the inverter should the grid go down.
I'm not aware of any instances where a correctly installed grid-tie inverter has caused a hazard to linemen.
There are documented instances of inverters that are not intended to grid-tie and domestic generators being incorrectly wired to back-feed and worker deaths have been reported.
It is vital to use the correct type of inverter and connect in the approved manner.

With no cash how to I buy the nice Thai policeman his "tea"??
Seriously, I'm >90% digital payments of various flavours, even the local Mom-n-Pop shop and food shed have PromptPay QR codes displayed.
But I always carry enough cash for a tank of diesel, just in case.

Could you make alternative mechanical arrangements but still using micro-switches?
