    few questions about solar power....

    Sorry out of the country ATM so haven't been so active . They're pretty monstrous 50% heavier than a typical 400w I'm pretty sure china just use SEAsia as a testing grounds there's very little difference in price to the smaller panels so your obviously just gonna buy big rather than try look...

    What was your most interesting recent non solar project?

    I mainly use them for my projects because of the Bluetooth every project I add to the house allows me to map a little better so it's easier to track my car keys when I miss place them

    Has anyone tried to use SRNE (Modbus ?) communication protocol with MakeskyBlue, PowMR or EASUN SCCs ?

    Yes there's a ton of multiplying filters if I remember correctly just had a quick look at the code for voltage and it's somehow offset by current input but not clever enough to work out how. lambda: |- if (!id(grid_active).state) { return 0.0; } return swapBytes(x)...

    Has anyone tried to use SRNE (Modbus ?) communication protocol with MakeskyBlue, PowMR or EASUN SCCs ?

    I'm away from home ATM so poking around my own code would be tiresome and possibly problematic but what I can tell you is I use a max3232m to convert from rs232 to uart I vaguely remember much of the hardware being described badly on the odya github tx/Rx being mixed for starters though with...

    What was your most interesting recent non solar project?

    How's the pwm signal? I gave up using 8266 as it's all software defined but my use case was lights and far more obvious esp32`s are hardware based so I got far better results though it didn't help I already had alot of pcbs that were based on the D1 mini, thankfully I got a hold of a few D1 32's...

    How do you make battery cables fit on battery terminals that are small?

    Cheap here in Asia but almost everything is Not sure I think they sell them in the US places like Walmart might stock them so I would guess they have a decent comparison chart if not awg specific sizes.

    HA on RPi?

    I'd consider these thin clients or sff (small form factor)really, but exactly what I would suggest to run Home Assistant. Micro pc's should actually be micro as in not much bigger than a pi but this is all semantics and better left for another day😉 one thing I would point out is if you intend...

    DTLC crimps are likely your best bet

    Has anyone tried to use SRNE (Modbus ?) communication protocol with MakeskyBlue, PowMR or EASUN SCCs ?

    I know it's for esphome but if you take a look at this it might give you some answers the modbus info is under src/modules/inverter. https://github.com/odya/esphome-powmr-hybrid-inverter

    Stumped: Can't figure out these dips / fluctuations in power graph

    Is this off-grid, are you charging you batteries during the dips, what loads are you using? There could be many reasons for the dips not just clouds your panels will only produce as much as you can load them, if your adamant that there's no clouds I'd put good money on your load dropping off...

    HA on RPi?

    With sd cards and usb sticks it's more to do with the limitations of the nand chip, you might currently have better luck with usb but I would say given time that's going to fail also they just aren't designed for that many writes and will slowly corrupt/die. If you want to keep your data id...

    Long run (1400ft) Fiber Optic Cable vs Starlink Internet?

    Might be hard with a 500ft roll of HDPE, long ass stick

    Long run (1400ft) Fiber Optic Cable vs Starlink Internet?

    HDPE is pretty good tbh I wouldn't go with thin wall because of the dirt but it shouldn't get taken out by the critters. As sparky said get some light strong string tie a plastic bag on the end and use a good shop vac on the other end 1400 ft is pretty excessive never tried it at those lengths...

    HA on RPi?

    Are you worried about power usage? If not I'd recommend an old office thin client they don't use much but considerably more than a DC system like a mini pc or RPi you can normally pick them up for £50 or so like the Lenovo think center, then if one isn't fitted it's matter of a small SSD. If...

    HA on RPi?

    You can install HA core as a docker image, It's far more complex (steeper learning curve) and you would have to install each add-on independently but from what I've heard from others is it's far more stable than OS atleast on RPi 4. look at Home Assistant Container install in the install...

    Solar Assistant graphs freeze up

    Might be possible to emulate a pi on a x86 machine and try to install SA on that but the chances are pretty slim.

    Don't think generations has anything to do with it I'm not 40 yet but I started work in the local outside market at a very early age, I would get up at 5:30 help setup the market stall go home bathe then goto school then return to the market help dissemble then go home and likely work/tinker on...

    Post your Ground Mount Setup

    I grew up in the Welsh valleys where many houses were built of Beaufort bricks which were known to be one of the hardest in the world, the US shipped something like 40,000 of them from wales to NYC for the foundations of the Empire State building. Tradesmen hated them as trying to fix anything...

    The plan so far, thoughts and suggestions please

    So I've changed my mind again.... Current plan: -Deye sun-5kw inverter It has better support for my use case (esphome) compared to the solis and at half the price of the 10kw I can run two in parallel if one isn't enough. -Longi 375w mono panels x16 Two strings of 8 brings me to 6kw total...

    Pretty good price might have to treat myself also looked at the slightly cheaper version and that's the potato quality I though most of the plug phone versions are.

    The plan so far, thoughts and suggestions please

    I can but the domestic market is so much cheaper I'm currently looking at lvtopsun 16s 234ah batteries they come in at 55,000 baht which is equivalent to $1500/£1200. I've also noticed Deye 10kw single phase inverters are on the Thai approved inverter list, double the price of the 5kw and 6kw...

    few questions about solar power....

    Sorry I stand corrected lazada.ph is a minefield of junk best I could see was 560w jinko panels but a single is near $150, not posting a link as I don't know how to break it up from being affiliated therefore against rules.

    Please point out my mistakes

    Others will be much better at pointing out any finer details as I'm still very much a novice but one thing jumps out at me and that's voc with the two panels in parallel the voltage will likely be around the 30v mark, looking at the mppt SSC it only said that voc needs to be below 150v but no...

    Our 10.6kWp grid-tie hybrid system in sunny Thailand.

    Nice setup, hoping you can answer a few questions since you have some experience on the matter. How do you find temps with the Lifepo4 cells I went FLP with my off-grid system but the batteries were only a backup for power outages now I'm looking at a larger system Lifepo4 seems the way to go...

    How can I use Hyundai EV batteries for stationary use?

    I've noticed BYD modules coming up for sale here recently around 25v per pack but the busbars BMS wires are pretty much exposed so converting to 48v and adding your own BMS seems trivial the only issue here is price, people in Thailand don't seem to understand pricing on the second hand market...

    The plan so far, thoughts and suggestions please

    So it's a complete shambles it seems I was thinking the price wasn't that different compared to DIY but after speaking with the supplier the price kept going up and up. It works out at £2000 per unit not including tax which is crazy for the Asian market so I think I'll scrap that idea and either...

    Long run (1400ft) Fiber Optic Cable vs Starlink Internet?

    I've used and fitted a few they have their downsides but generally work well Doesn't apply completely in this case but overhead sling fibre in my area gets destroyed by squirrels regularly, pesky things can't bite through wifi Protection is key especially if op is in an area with ground...

    Long run (1400ft) Fiber Optic Cable vs Starlink Internet?

    Agree with the above post if you have the power available,line of sight and some form of locked enclosure, PTP is a viable option I've seen a few that can work upto 15km and the latency would likely be far less than starlink

    The plan so far, thoughts and suggestions please

    Spoke to the company this morning and got a realistic price of $1200/£1000 per unit which is still very good for a 14.3kwh premade but not the stupid bargain I thought it was, they will get back to me with shipping costs later so I can consider that with my price. Thailand only really has 1 or...
