January 21Jan 21 Popular Post 28th-29th January @ BITEC Bang Na, Bangkok - Free to attendhttps://maps.app.goo.gl/3rbjoSDQbt7DhLs39https://www.terrapinn.com/exhibition/solar-storage-live-thailand/index.stmI hope to identify any new or interesting renewable technology available in Thailand and will share what I find here. Anybody else going? I am sure someone will say that it's a B2B event only but I have attended several times before and have successfully registered again this year, my job title is retired at retired.In 2017 I was quoted ฿150,000 for a 5.6kWh Li Battery!
January 21Jan 21 We are going, flight arrives 10am although I’ll be at the show on my own, staying overnight on the 28th at the Thomson Residence and flying back 29th afternoon.Happy to meet up for dinner on 28th if you like, probably a restaurant in Mega Bangna.

I will DM you. I don't fly internally in Thailand now that I have an EV. We are staying at the HOP INN in Bangna with lots of parking and only a few minutes walk to BITEC.

January 21Jan 21 Popular Post Just to meet up would have been nice but still completing our 3 phase 20kW solar installation. Waiting on a replacement phase protector for the ATS.Today changing the EV charger position and from single phase to 3 phase.I will detail the installation in the Alternate Energy Forum when I finish.
January 27Jan 27 I'm going today, I hope the Fahrenheit buffet is open, last time I was there it was not open.
January 28Jan 28 Author Popular Post Some photos from the showChaweewan had a Sigenstor Inverter, Battery and 25kW EV DC bi-directional charger stack, which was nice to see in the flesh.They have recently installed a double Sigenstor stack for one of their customers.

There seemed to be more people in the food court than walking the floor. Could be the market is saturating, and the exhibiters did not see any real return last year. We used to do the Bangkok RVAC show, and while I loved doing it, it was a big loser for us.
January 28Jan 28 Popular Post It was our first show. I was surprised at its size. But I found what I was looking for, an installer introduced by Bandersnatch at the show (thank you Paul) and 2 Chinese manufacturers of inverters and energy storage systems, these latter 2 I think will provide some competitive quotes.
January 29Jan 29 Make sure that anything that you import to Thailand that requires some sort of testing/approval is quoted delivered duty paid (DDP), to your door.If a product is not already approved for use in Thailand, you can get stung for the testing/approval fees which are not insignificant.

January 29Jan 29 Author I really like the SigenStor setup, but the inverter size for single phase is limited to 12kW while it's 3 phase is 25kW. The bi-directional charging needs to be confirmed for either my BYD Seal or BYD M6 EVs, will wait and see.The price of high voltage stacking batteries systems seems to be over double what you pay for low voltage stand alone batteries.This is my current setup Main system:20kW + 30kWhIt can't be expanded any further.Backup system:Luxpower 10k + LVTopSun 10kWhI've been very happy with the Luxpower + LVTopSun4x16kWh =64kWh ฿65Kx4 =฿260KLVTopSun also do a high voltage stack but it's twice the price.
January 29Jan 29 Author Just now, Yellowtail said:Wow, that's impressive, and a lot of power!Thanks, but my main system dates back to 2021 and my house is off-grid with 2 EVs to charge.I plan to replace the 4 x 5k Growatt inverters and the 4 x nRuit batteries. As with previous upgrades I am donating them to a friend.Current plan is to add another 25kW of PV, 4x16kWh LVTopSun batteries and 4 x Luxpower 14kW inverters. Next week the plan might be different

And might be why they are more costly and also considered the built in safety?

I might incorporate a "small stack" in my system:12kW single phase inverter linked to 12kW of solar25kW DC bi-directional charger2x10kWh batteries With top up AC input from my main system replicating a grid connection It could be positioned between my 2 EVs
January 30Jan 30 Author Having mentioned the LuxPower inverter, I thought I should also mention that they are very popular in the US. They are rebranded but you can still see the green LuxPower logo in the corner
February 3Feb 3 @Bandersnatch - may I ask how much you've spent on your hardware and what sort of payback time you estimate?Did you buy everything in Thailand?How about telemetry of the various components in terms of the data provided and the ease of acquiring and saving the data?Interesting thread by the way.

But it was a good learning curve and equipment has all got cheaper and more reliable.So I just chucked it and spent 20kbht on new panels and inverter which fills my entire household and driving needs (3 year warranty on inverter).The people on these threads all have grand plans costing $$$$$s, but you can get a good return on quite a small investment.

February 3Feb 3 3 minutes ago, Yellowtail said:Do you use batteries at night?I used to, but now I use grid tie, and turn off for the days when a meter reader is coming. The battery from my old system are still connected, but only get used if the grid fails (16x CalB 200ah, must be 15 years old now, maybe still good for 50ah)
