    Is my water tank safe?

    Well water here (well bore water) is considered non potable where I live, and is allowed to only be used for agricultural purposes (plus it tastes bloody nasty as hell lol)- anyone relying entirely on bore water for potable purposes has to have a 'treatment plant' fitted and undergo regular...

    Is my water tank safe?

    It is actually a legal requirement in many council areas that tanks have an approved standard fitting that the bush fire brigade can connect to... (in my case a 65mm Storz outlet is required at the tank itself...) One of these Basically, a T fitting is fitted to the tanks outlet valve, one line...

    Is my water tank safe?

    They are quite ok for drinking water as well, if kept out of the sunlight (I ended up wrapping mine in shadecloth- also kept their temps down in 40C plus temps) plus add either 'tank treatment' tables (widely available from most hardware stores or rural suppliers in Australia, or even a small...

    Advice for lifepo4 in very hot temperatures.

    One way is avoid using LFP (only common in the southern states in Australia lol)- LYP or LiFeYPO4 cells are FAR superior in both hot and cold conditions (they are a little more expensive than LFP, and have a lower energy density than LFP (so slightly bigger than LFP) but can be used at their...

    Running 240V water heater on 120V?

    At least in Australia, most HWS are rated for external use, so if yours are similar, then just run pipes outside to it (at worst you might have to built it a little 'leanto' to house it in...

    power supply

    I have two of those identical units (sold under a different brand name ie QH, they are all the same I have found though) and they are NOT a charger, but a power supply (although they can be used as a 'dumb' charger) I use as my 'extra' bench PSUs (they are actually quite a good little unit-...

    Raspberry PI Power Supply

    The PI has a bad rep when it comes to its 'USB power input' it demands 5vdc, but the USB spec is 4.5v to 5.5vDC unloaded, so you can have a 'legal' USB power supply that won't run a Pi... Plus many 5vdc supplies are woefully underfiltered and will add 'hum' to the output supply, in which case...

    Is my water tank safe?

    Food grade IBC's are commonly available and quite cheap (I paid under $180 for my four) they used to contain canola oil used for cooking at 'fish and chip shops' but were pressure cleaned before I even got them... On the way to the campsite on my then new property 3 were used as 'storage', the...

    Mounting panels with unistrut

    Done 'far too many' marine installs on panels on ocean going boats, and I can say with certainty that panel mounts are an issue wherever they are exposed to sea spray... My personal favourite installation method is to use rubber strips to separate the panel from the 'usually' stainless frame...

    Grid Tie Victron ESS with DIY LiFePO4 Battery in Australia - Regulatory Issues?

    I suspect it is simply a cost/benefit tradeoff- Victron don't sell that many inverters (and most of their users are offgrid anyway) and getting compliance testing done is EXPENSIVE!!! I don't know what it would cost to get it done, but it is BIG $$$- I know just for a simple testing done for...

    New Tariffs in the States

    BYD doesn't currently sell ANY hybrid in Australia, or indeed anywhere else but China AFAIK, although that is about to change this year with them bringing out the 'ute' to Australia The BYD Shark, the first BYD ute, is supposed to be on sale in early 2025, there are at least one and maybe two...

    New Tariffs in the States

    You REALLY need to vet your sources more carefully- I didn't even need to watch it to know immediately that was a video by a utuber named Sepentza- a notorious antiChina (and rabid anti EV) utuber with a long history of 'distorting the truth' aka lying... (he is a far rightwing supporter, born...

    New Tariffs in the States

    And to address the 'lack of red tape'- a gridtie or hybrid system in Australia requires installation of one of the 'Australian Standards Tested and Approved' inverters only (which can cost between $50k to half a million to get an approval per model, no approval, no install it)- to install the...

    New Tariffs in the States

    LOL- you yanks get much larger rebates than we do- in my state (Qld) there is no state rebate at all for a gridtie solar, and the federal government rebate is $400 Au (some states do provide a small rebate as well- two match the federal rebate $ for $)- that $8000 rebate was when the scheme was...
