What's the net metering situation in Thailand. I assume not that good if you decided to get storage. Did you get a lifepo4 battery?

- jpgvm 3y agoThere is net metering but it has two major problems. 1) It's hard to get approved, doubly hard for a DIY installed system, even if I could jump through the hoops (eletrical engineers drawing etc) there is also a quota so there isn't a gaurantee it would be approved. 2) The rate isn't that great, it's about 30% of retail. However all of that is moot in my case because my power needs exceed that of the available utility power at my location. So I essentially have a 3 phase completely off grid solar system. So why did I say hybrid? Well that is because I do have a utility supply but it's a 15/45A supply but it's got horrible voltage drop (I'm 2.5km up a mountain from the transformer) and it's 1ph and I need 3ph power for my EV charger, air conditioning and pool pumps. So what I did was add an AC charger that is configured to charge from grid if the batteries drop below 30% state of charge. So it's essentially a hybrid system, DC coupled to the 48V batteries but really the grid supply is just a backup, the system is specced to operate completely off-grid. Yes the battery system is LFP, I went for 5 x 48V 200AH server rack mounted packs in parallel. I'll probably also eventually add a diesel generator so that there is no way I will ever lose power but for now the batteries + grid charger are going to be enough.
