For a couple of grand investment you can't go far wrong. It even has a phone charger built in.

Sorry guys, but I see absolutely zero value in this thread. If you can PM myself or any on-line mod with a really (really, really) good reason to re-open we will consider.

Do add up any other stuff too, you may want lights etc. A proper energy budget calculation would avoid disappointment ????

A very "finger in the air" guesstimate:- Assuming off-grid (no mains power) you would need batteries to even out the solar energy. If you say a fan of 120W or so then you should be able to run that all day from one 330W panel with around 500Wh of battery to handle the peaks and troughs in the solar. So something like:- 330W poly panel. 50A MPPT solar charge controller. 300W inverter (or a 12V fan). 12V 100Ah deep-cycle lead acid or 12V 60Ah LiFePO4 battery pack. Of course if you are going to want your PC, phone charger, power tools etc. etc. then that's more panels and more batteries. If you want A/C, say a minimal 9,000 BTU (in a small room of course), that's going to use about 0.3kWh per hour of use, about 3-4 times what the fan would. So multiply the above by 3-4 ???? BUT you would want an inverter type A/C due to regular A/C units having a large start-up surge which would need an over-sized inverter. To do it properly you need to do an energy budget calculation taking into account everything you want to run and how long without sun you want to run for.

Oddly enough our actual overall energy consumption hasn't really changed (30-40kWh per day with a peak on the weekend when we have family over), we are just buying a lot less from PEA ????

My site is dust I'm afraid, however you can still find old versions on the WayBackMachine and the plans are still there and downloadable. The site that @Jai Dee links to does contain most of them plus some new ones. I sometimes wonder if we should have built this (floating house):-

Meanwhile, back at the ranch! Note:- I've not verified that this is actually correct, please check before travelling. https://milelion.com/2022/06/06/thailand-pass-entry-window-tightened-to-3-days-again/

If you can't find the correct thread then simply drill and tap the fitting that came out of it to any size you like???? EDIT 3/4" NGT or NPT do seem to be the standard https://www.bestmaterials.com/PDF_Files/propane-fitting-threads.pdf

Yeah, our baby "starter" system has ballooned from 4 panels to 32!

@itsari Do you have a rough budget? As with all this kind of system the batteries will be the limiting factor budget wise even with generic 48V units. A 10kW system will generate about 35-45 kWh per day during the solar active hours (2-3 hours either side of mid-day). We are getting just over 1,000kWh per month from our 10.6kWP system just north of BKK. How much will you need to store? Try reading your meter at say 4PM and again at 8AM next morning to get an idea just how much energy is being used during the non-solar period. I'm thinking going grid-tie hybrid (see my pinned thread for the different system types) with the inverter "emergency power" (UPS) output feeding your essential services. Probably go 2 x 5kW inverters for your 10kW system.

Even the old "weatherproof" meters do have limits

Definitely put it in a suitcase, cardboard boxes do seem to attract attention, pack your clothes around it. In the naked box it also stands a good chance of getting damaged in the airline luggage mangling system. The airport customs chaps are after the easy targets, booze and tobacco (fixed limits, easy penaties) so the chances are that even if you declare it they will simply wave you through after some head scratching.

2450 MHz or 2.5GHz is the frequency band in which the microwave "broadcasts", the same area as your 2.5GHz router does. It's not unknown for the microwave to screw your WiFi, move the WiFi to the 5GHz band.

Efficiency. 800W of cooking power using 1159W of input energy, so about 70% of your input energy goes into the food. Maybe!

A grammar/spelling police post and response has been removed. Fixed the topic title ????

The way today is going I suspect I'll be working tomorrow ???? At least it will be from home.

Just Friday.

Will he also arrange to pay the 30 billion (yes, billion) Baht that is owed to BTS for operating the Green Line extensions??

Yup ^^^. Do you have butter and cheese? On my way round ????

What's the power of your pumps?? How long do you need to run for?? You may need to consider a genset as backup for the backup.

An off-topic post (and sensible reply) deleted.

We DIY'd a system with (now) 10.6kWP of panels, grid tie with 10kWh of batteries (going to expand "soon"). Thread here https://aseannow.com/topic/1120934-how-about-a-solar-car-port-on-a-budget/

I assume from the silence that you have had no progress on the batteries or export meter front? ????

Have a read of this thread https://aseannow.com/topic/1207148-my-issan-10kw-on-grid-solar-project-fully-installed-by-contractors-337500bht/ @Thaifishwas going to update to include batteries but I think has run into battery supply problems. The contractor looks good but I would avoid the Huawei equipment as it requires special (expensive) high-voltage batteries. A more genereic 48V system should prove more economical. Are you looking to go off-grid or merely use the batteries as a UPS for critical power? How about selling excess to the PEA?
