5.4 Kwp + deye 5kw + 7 KWH battery = 160k

Inspired by others sharing their projects I thought I'd share mine. Solar was on my mind for long time so I was plotting everything just for fun.
came up with ideal solar panels size for my roof and inverter MPPTs. Was researching what inverter make sense for me , knowing outages are annoying around here and ups batteries for my office only lasted a year 
i decided it has to be hybrid. Also thanks for this forum knowledge I definitely don't wanna do business with PEA. So the plan was small battery for outages, spinning meter backwards responsibly when nobody's looking.
Plan was to cover my bill 100% but here where I was wrong. I had this done since may but i am constantly 25% short on production. That might actually be a good thing. because i don't wanna raise suspicions suddenly having zero bill
Anyway... with my setup i can overpanel current inverter, add another inverter and another batteries. This could be done cheaper but I value functionality of Deye inverter and properly communicating lithium batteries too much.
i found my crew on facebook group โซล่าเซลล์ รับงานติดตั้ง และหาช่างราคากันเอง posted picture of my roof and exactly inverter and panels size i wanted ( no battery no PEA certification). I got a lot of messages  
  One nice lady gave me estimate with exactly what i wanted done for for 113K. For contrast other big company gave me estimate for 180K + 5k  discount voucher. You know which one i went for. I have experience in electrical and construction so i know i could supervise this project. There was little quality problem that was fixed with extra  6k bath and extra day of work for them. Basically  they went against my plan and started placing solar rails one row lower because it was easier to remove tiles. Went with this for first part of day which i regret  then talked with them and we decided to redo this with extra payment. They showed up with panels, inverter did nice  electrical work, questionable but corrected roof work  and i am happy. Battery i added by myself later . Also i helped with hanging inverter and combiner box and separated circuits so their work is easier,

SO:
inverter deye 5k + solar 12x bifacial 450W + labor = 120K
battery 7kw  = 40K
total 160K

i recommend browsing this facebook group , there is a lot of advertising from wholesalers  and prices for installers are very good 
you can catch good deals for panels too

Thanks for sharing!

That is a very clean and neat electric installation you have done in that cabinet, very professional.

I love DIN-rail. :biggrin:

I think we are both using the same temperature controller for external fans, I replaced the temp sensor with one looking like a cable lug that I screwed directly to the inverter.

those combiner boxes comes ready with installers all you do is connect your solar grid and inverter. I was pleasantly surprised how cool it is. didn't even know i will get load meter and v/a protector. 
this is how i solved sensor connection (pic) paper clip and thermal paste 
using double pwm controller (in case of future second inverter ) triple pc pwm fans connected to splitter. Only consumer 1.3w at idle and 11w at full steam. works great
