  1. Just had 4 a/c units cleaned inside and out by my air con man. They had a miniature water blaster and purpose made bag with snout that fed the waste water into a bucket. Spotlessly clean after they had finished. I would change my a/c service guy if your not happy with the job or tell them you want a guarantee they will not to make a mess while cleaning. Its amazing how much <deleted> gets past the first screen filters. I would much rather pay someone to do the job than me doing it.

  2. So my quote came in for a 30KWH Huawei battery storage system. Click and Play... Sit Down before you read on... 790,000Bht.. Includes 6 x 5Kwh batteries split over the two Inverters + Power module and Battery Module...  A link to the  spec page...

    It is killing me watching excess power just being wasted. ~20 +Kwh per day. The Grid Smart Meter will help I hope but it is looking like only 50% return on what is being exported... Time will tell... So research on installing batteries other than Huawei with their ridiculous cost has become a priority so I don't end up with a white Elephant. By not using Huawei Click and Play modules I can see it is going to be a challenge for me setting up a battery system which would obviously be cheaper than their quote.

     

    A question for the Gurus which shows my limited knowledge.

     

    The simple formula  W= Amp x Volt. If I have 5 x 24V x 260Ah batteries.  260Amp/h x 24V x 5 Batteries = 31,200Kwh. So will this supply the 30kwh at 220V I want? (I cant understand how at 24V production and then using power at 220V the Kw can be the same if you know what I mean??) I can not get my head around it!!

    solar panels could be placed direct on the roofing, the shapes on the roofing works as rails. If i go that route i need some way to fasten the panels, any ideas?

     

    Many ways to fasten. I would rather build up of the roof to keep the PV's cooler and more efficient. TOA sells aluminum braces 15Bht per meter. Right angle brackets to fix PV'S 5 Bht each.. Not sure of price of tech screws but needed... Less holes need drilling through the roof to fix this way....

  4. Monday 31/5/21 and PEA turned up and installed a new meter. Yep no feedback to the grid. Hindsight!! Should have set system to non export around meter read time. Anyway no hassles and no fines.. Was exporting low 20kwh to sometimes 30Kwh back into the grid so now it is just wasted power going nowhere. Obviously a big bight on ROI also!!! So now still waiting on the already purchased Smart Grid Meter 4 and a  half months ago to come from Korat PEA so Nang Rong PEA can install. I don't know how the new meter still waiting on works with feed back into the grid. I am hoping it is 1 for 1 and the leftover when the meter is read you get the rebate 2.2bht p/Kwh. In other words I hope it is not ratcheted so export Kw is the same as whats being fed back into the Bahn..

     

    My monthly output below.... Averaging 40kwh production per/day. Can't complain about that with a lot of cloudy days and rainy afternoons..On the 1st day of the month the grid was down for 5 hrs...and of course a sunny day... 1.24Mwh production for the month.

     

    For the hell of it I am getting a quote for a Huawei Battery with 25KWH supply for overnight consumption.. I know the cost will be over the top...

    I have not thought of using a car radiator fan for the roof. What a brilliant idea! 

     

    Car radiator fans cost me 500bht each from wreckers.. I had 3 x 12v x 40watt PV panels laying around doing nothing. Not sure of price as I bought them years ago for a dam oxygenator. The radiator fans can handle 80watts so mine are way under powered. I'm deaf but I have asked the Issan Luv Machine if she can hear them running which she said she can but not a bothersome noise. A bonus side is we used to have a rat problem in the roof space which the fans seem to keep them away now. I have not worked out air displacement. I have tell tails hanging outside the vents so I can see the fans are working. 

  6. @4myr. Everything you are looking for is in my system I just installed Feb 2021. As @Crossy mentioned have a read of my thread. I could not fault the contractors workmanship they were organized. I did have some software issues which you can read about in my thread. The inverter I installed is a Huawei brand with connections to install batteries at a later date. Part of the installation quote included a Grid Smart Meter (PEA). I was told it could take up to 6 months for PEA to install. I was/am planning on selling power back to PEA for 2.2/1.9 bht p/Kwh. PEA say verbally 2.2bht but I have read and also heard 1.9bht? I have been warned that to install the smart meter there is a lot of paperwork and a PEA inspection of wiring. The reason I am mentioning this is in hindsight maybe I should not have ordered the Meter. One reason is because I have not been exporting as much as I expected. The second reason more importantly is the meter I have already is an older style which spins backwards with export power acting like a battery storage for overnight.   It is illegal but common practice. The Huawei inverters have no fans and does get warm but that is the design. The cooler you can keep the Inverter the more efficient it will be also the longer the cables the more power you will lose over distance. For roof cooling I have set up 3 x 12v car (brushless) radiator fans bought from wreckers and mounted them to the vents. I power them with 3 x 40w solar panels. Good luck if you can find a sparky to do the installation correctly. I have 5 years warranty. @Crossy is on the money with his answers to you. Feel free to PM me.

  7. My production for April.... 1.15MWH. I had my software issue with readouts sorted on the 6th so a bit dubious about accuracy although my manual readings from the Grid Meter appear to agree with the production. As you can see consumption is higher than production. A few words where had with the "Freeloaders" end of month about maybe they could close windows and doors while the A/C is on and turn the lights off when not being used!!!! etc etc etc. (Need to make a note to myself to count no solar panels missing). The wet season has kicked in early this year with afternoon cumulus build up and lightning to boot. I'm happy with production....

    OP, how difficult was it to obtain permission from Oz gov to exit Australia?

     

    It is the easiest part of the application. Make sure you give a good reason why you wish to travel ie to be with spouse....Do not say Tourism. Also make sure you tick the box that you intend to stay outside Ozz for 3 months or more.. You will get a reply within 24hrs.... Copy the approval and show at the airport.

  9. Anyone wondering if The Ozz government ie. Bangkok Embassy is going to help out Ozzy's in Thailand with getting a Vaccine shot have a read below. Im not sure if link will work?? You might have to copy to Browser??

    COVID-19 vaccines: Frequently asked questions

    Will Australians overseas be included in the vaccine roll-out?

    Australia’s COVID-19 vaccinations will be available to people in Australia. The domestic rollout does not extend to Australian citizens while overseas.  

    If I have a vaccination overseas, will I still be required to quarantine on return to Australia?

    At this time Australian Government advice for international travellers remains unchanged.

    Australia’s borders are closed. The only people who can travel to Australia are:

    Australian citizens

    residents

    immediate family members

    travellers who have been in New Zealand for the previous 14 days.

    Passengers travelling to Australia must be tested for COVID-19 72 hours or less prior to the scheduled flight departure, and display evidence of a negative test result at the time of check-in. 

    At this time, vaccination against COVID-19 does not change the requirement for mandatory quarantine for 14 days at the port of arrival. Travellers might have to comply with other state and territory travel restrictions. For more coronavirus advice for international travellers, visit the Department of Health's website. 

    What is the Australian Government’s advice to Australians overseas on seeking or receiving a vaccine offshore?

    You should consult your local health professional for advice on vaccine options that may be available locally. 

    The Australian Government cannot provide advice on the safety, quality and efficacy of vaccines that have been approved for use outside of Australia's regulatory process. 

    I’ve been provided by Home Affairs with an exemption from the overseas travel ban to travel overseas, how can I access a COVID-19 vaccine before I’m scheduled to depart Australia?

    The Australian Government is committed to providing all Australians with access to safe and effective COVID-19 vaccines as soon as they are available. Access to vaccines during the early period of the rollout will be made available to highest priority groups. 

    Find out more about Australia’s COVID-19 vaccine rollout strategy and priority groups for COVID-19 vaccination in Australia.

    Will the Australian Government provide me with financial assistance to access a COVID-19 vaccine while overseas?

    Do you mind to share your installer for your place as I am keen in this Huawei system as well.

     

    No problems.... The link to their homepage is below.. I will PM a direct phone contact also.

    Good to see someone happy to stick with the Huawei product after a previous installation.

    64 too high, 16 too low ...........

    Let's hope for a sunny day so we can see if my prediction of 35 units/day is correct.

     

    Another day as it happens.... Noticed production not as good again as I would have expected even with clouds the last few days.. Slowly getting in sink with what I would expect with the installation performance..  Even though all lights blinking green like " Thunderbirds are Go" Something appeared amiss. With software operating now I picked up that one of the inverters was not operating since the tech guys were here. A phone call to Contractors and 30 minutes later the errant inverter is back working again. All rectified by internet connection. I could see that the inverter had not started up as the software tells you down to the second the start up time and shutdown time. The production attachment below shows a bump in production around 1430 hrs when 2nd inverter was kicked in by Contractor and the other attachment shows hours etc inverter online for the day..  

     

    I hope I beat 35 units... I'm confident I will.... In fact I'm sure I will....

    reminder it is strictly forbidden to connect your installation to the public network without authorization from the unencrypted operator to run the meter upside down
    the risk of sanction if the operator finds out about the thing, he will install a way acronym at your expense, i.e. around 10,000 baht and may, in accordance with the regulations, recover the amount of sums that have escaped him by the drastic amount of the counting

     

    SPREX it looks like you have already done the hard yards getting set up to sell extra KW back to PEA. I have been warned it is a mammoth task. I am on the waiting list for the smart meter already paid for in the installation.. Maybe 1 month to 5 months to go now. In hindsight after 6 short weeks of installation I am wondering if the smart meter was the way to go. On average I have been consuming 10KWH more than what has been produced in a 24 Hr period. The old meter I have appears to spins backwards at the same speed as it does forward with similar Amp's. I was of the understanding that the meter would be ratcheted and spin backwards at a slower rate. The Smart meter may go backwards at a slower rate.... ie be ratcheted?? I don't know.. Time will tell... What I do know is the old meter is a great storage of excess power. I'm sort of wishing to keep it now. The installers and My Issan Luv Machine are not concerned about the feedback of power back into the grid and PEA finding out.  (famous last words)!!!

     

    On a bonus side of not exporting excess power back into the grid means I have not over capitalized with a 10Kw system. I am effectively getting a return of 4.2bht/KWH produced instead of 2.21Bht/KWH selling price. I was quoted by Nang Rong PEA 1.96Bht purchase price P/KWH verbally but I would agree more with your purchase price of 2.21Bht (2021). I read that also in some PEA literature.
