Well the river level doesn't really seem to be doing much, 110cm below my reference "worry" level. It's high and plenty of areas are flooded but it's not really moving much, at least not yet.

Meanwhile, on our side of the same river, in the same area we are now 140cm below "worry" level. Yes, many of the village houses are using boats but the occupants just get on with life. What's coming from the north ... EDIT Madam has suggested that some jealous (flooded) people "might" have opened some floodgates! This happened last time too.

Yup, that's the beast. Arrow points towards the meter (incoming supply) if it's installed on the live wire as per the instructions. It WILL work on the neutral but needs to point the other way.

Working from memory here but IIRC disconnecting the CT will NOT make it export unless the solar input is zero (the inverter stays at whatever power it was generating at the time.). Connect the CT at any time and it will stop export immediately. We only change our CT connection at midnight coz that's when the auto system does it.

Yeah, I've had a couple of refunds to card take rather a long time, but they've arrived eventually.

Could be the wrong setting? On your inverter it's "Reflux Power" or "Anti Reflux" I think, check the manual. "Reactive" is something else and should be left as default (it's used for correcting poor Power Factor).

Yeah, and I see the new house on the other side of the road where you hijacked the crane from to install them ????

Yellow Pages is much better

Cable length won't be an issue ???? To isolate the CT you just need to break one of the wires, it's low voltage/current** so any cheap switch will do the trick, I used a 125V rated miniature toggle switch. ** Do note that these high-frequency "transformerless" inverters can often give a "tingle" on the interface pins, so do kill the power to the inverter before handling the wiring. It's not going to do you any harm other than making you drop the screwdriver, but best to be safe.

Yup ^^^, sticking another pack of the same voltage and chemistry in parallel will work just fine. Of course, the combined packs will take longer to charge assuming the UPS charge current remains the same.

I shall refrain from further comment until the results are in unless someone posts something that is hazardous to life.

The problem is that "zero" fits nicely into the "up to 30%" bracket. I'm afraid that 110% of the devices promising to save on your energy bill with a simple plug-in device are all smoke and mirrors. By the way, the water demo works just fine with an unprotected supply. Reasonably pure water is a pretty poor conductor. Ask him to get hold of a live conductor and I might take notice.

Start here:-

Meanwhile I have a system that saves me up to 90% of my electrical energy bill. Documented and verifiable in my thread in the Alternative Energy forum.

This is a major red flag!!! It will be most interesting to see what actually occurs. But there is no way that a device as shown in your photo could be anywhere near fast enough to prevent a lightning induced surge. Sustained over-voltage yes, but there are plenty of those on Lazada. Please do post your better video.

Meanwhile the wet is also piddling in through the roof of the Pink Line Operations Control Centre, not made it into the news ???? Same civils contractor!

Borrowed from another Asean Now forum...

Not cheap indeed, but most definitely not that expensive either. A decent quality on-grid hybrid inverter which incorporates the MPPT controller, DC-AC inverter and battery charger runs to about 48,000 Baht (1,100 squid or so) for a 5kW unit, there are cheaper units available of course. We have one of these https://www.lazada.co.th/products/solar-sofar-hybrid-on-off-inverter-hyd-5000es-50kwpea-list-approve-i2064152396-s6736374882.html I wouldn't use Li-ion batteries, they have a nasty habit of going whoosh if abused, LiFePO4 packs are much safer (although they still need appropriate safety precautions), a 48V 100Ah pack (About 4.5kWh of usable storage) runs to anything upwards of 50k Baht, DIY a pack with second-life cells and you can go cheaper if you like. Panels are about 3-4,000 Baht for 340W polycrystaline, a bit more for mono. Most panels incorporate bypass diodes which will mitigate shading to some extent although not as well as panel optimisers (but IMHO spend the $$$ on more panels) or micro-inverters (good luck adding storage).

They even say they have supporters around the globe!!

Conclusive proof!!

Late update today (some of us have to work). 112cm below "Worry" level, currently reasonably stable. We shall see what happens when the latest deluge arrives from the north.

The 10 and 25A ones are readily available in the DIY places, bigger ones from your local electrical emporium. There are my go-to connectors for pretty much anything, put solid, stranded (with or without a ferrule) or even a lug if you feel that way inclined. I've seen box blanking plates in both plastic and "metal" just add a cable gland and you're good ????

Leaving aside the 50/60Hz issue I really don't see that you need this box as you are using LED gro-lights rather than HID. 8 x 1000W lights is about 40A (around 5A per light) so you could easily run them off 4 cheap timers (2 per timer). Setting the timers to slightly different start times would mitigate any switch-on surge issues. Something like this https://www.lazada.co.th/products/timer-kg316t-ll-timer-switch-220v-25a-i995590076-s2170728068.html A local sparks should be able to install a suitable breaker in your box and wire up the timers. One other important point. What size meter does your place have, most of us have a 15/45 unit (it's marked on the meter) which maxes out at 45A officially (many use a 63A breaker) leaving you with precious little for any domestic stuff, do your plants need ventilation for example. 8000W of LED is a lot, how big is your growing area, are you sure you're not going to cook the plants? EDIT By the way, 8000W of lighting is going to suck up 8kWh of energy every hour, so a 12 hour grow day would use 104kWh or about 450Baht at today's rate. Why an indoor grow when there's a great big fusion reactor in the sky blasting out up to 1,000W per m2 for free? Help it along with lights if you wish but the energy savings would be significant.

Has there actually been any further new on this discount? Such as the actual discount breaks in the 301-500 unit group.
