pcb has 2 channels . i bought it in case i have second inverter in the future. splitter is used to divide power to 3 fans so only one channel is used. whole enclosure is DIY connected with piece of aluminium and wood

that pcb is a controller and a thermostat and cost like 2$. (PWM smooth control) For me overkill is involving software and programing but you still need switch for the fans. also using home assistant for collecting data from solarman. Used it to calibrate termostat to desired temp. After that you can forget it.

temp sensor connected to heatsink also. fans starting to speed up above 39C. with this pcb fans idle always (1.3w) i thought it was strange but room could benefit from ventilation. monitoring internal temperatures with home assistant.

i added extra exhaust to the outside . 3 pc fans automatically controlled by dedicated pcb. Room gets ventilation and inverter stays cool. since installed internal DC temperature never allowed to reach 70 C

quite a upgrade. I got half cuts bifacials on the roof (p type) and is is possible to briefly get more than 100% out of them. Once i got 5650w out of 5400 array. i dont think that would be possible on 1 faced panels

do you provide work permit? what is a compensation?

whatever Deye cloud ( and home assistant using deye data) calculates is is off by like 2kwh a day. (pea meter spinning disc meter showing more consumption) i wonder if its worth to add meter like chnt ddsu666 (seen on aliexpress for like 15$) - would it calibrate deye calculations? also i dont want to look outside at the meter every couple of days , neighbor looking at me funny * i already tried to change CT ratio settings to calibrate it up and down and still error is the same,

type panels and stuff you like on FB search . Some wholesaler near you probably posted some advertisement. Respond. Might be necessary to chat to negotiate prize (use translator). Many times you can do cash on delivery or pickup yourself from warehouse. prices will be better than Lazada/ shopee that is what installers do anyway, if you find right people they will pass the savings to you and just come with all stuff and install. (happened to me)

facebook group โซล่าเซลล์ รับงานติดตั้ง และหาช่างราคากันเอง that's where wholesellers advertise to installers. Price not always include VAT tho

actually looks like batteries coming down and you can buy 300ah for something like 50k after all adds like that poops on my facebook

agree that for faster return on investment everything you mention can be done and working fine. for me Devil is in details. Deye likely to last longer and has more flexibility connecting generator/microinverter/ smart load ( ups mode has no delays) also is modular . Can expand system and connect additional inverters .Battery comms can be cloud backed and remotely accessed, including errors. so piece of mind , futureproofing system , and of course play with bells n whistles too. Couldn't help it

example? i think you talking DIY. OP might not want headache of dealing with that ready batteries that communicate with deye are something like 70K for this kind of capacity

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

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
