    Connecting battery to inverter, sparks then low-voltage disconnect?

    Despite me reading same, buying a resistor to precharge the inverter capacitors, in my excited haste i forgot all about that and did same as you. Mine was a 2000w 24v to 120v inverter (for a US bought AC vacuum packer) and it also blew all the internal 24v blade fuses inside the inverter so...

    Store temperature in ice?

    Thanks for taking the time to read and reply. Sounds like your location will have none of those issues. Only bit I can't get my head around is freezing inside out vs outside in being different expansion. Guess I need to brush up on that one.

    Store temperature in ice?

    I love building construction rabbit holes so just ignore if you want because it is a big off topic digression. I wrote it because the concept is a really neat (dare I say "cool"?) idea. A construction design to compensate for internal ice expansion so as not to crack the concrete would be...

    Cable lug crimping tool for 8AWG - 1/0AWG

    I should have given some context. It's the total cost inc ship and tax to Thailand. Very surprised to see the TH1818 hydraulic is cheaper than the TH0012 manual though. Saves me buying an electric impact driver for the little one.

    Cable lug crimping tool for 8AWG - 1/0AWG

    Nobody answered my post about the 3 point crimper with an electric impact. So much cheaper than the Temco

    4p4s 304ah... build starts today

    I know you will turn your 1500w x hrs into a capacity in watt hours but do a quick spot check on the battery cable amps with your clamp meter and also take the voltage just after you take the amp reading. It will tell you actual watts you are using throughout the test including inverter losses...

    Cable lug crimping tool for 8AWG - 1/0AWG

    Has anyone used this? You got my blood boiling reminding me of all my crappy big crimping efforts. I can get the Temco mechanical lug crimper but I think I saw Will in one of his videos use this one in with an impact driver? It says it also does up to 4/0

    Cable lug crimping tool for 8AWG - 1/0AWG

    I have that one (AWG) and a hydraulic crimper (mm2) and all my crimps are mm2 but as BobCollins said they all have to be designed to work with each other. Obviously the AWG has issues but I was disappointed the mm2 crimper doesnt work with my mm2 crimps. Also my wire perfectly filling the crimps...

    Nickel plating lessons

    Thank you to @FilterGuy for the resource on nickel plating. Worked great for me after some learning that had nothing to do with the resource information. Beautiful colour with nickel welding rods: Fake nickel strips because only plated: I first bought nickel strips paying very careful...

    Advice for Shopping on AliExpress Please

    A few years ago I happily bought inflatable boats, 5kw trolling motors, IR monoculars but NOT brand names (unless you count PARD as a luxury brand) but since covid hit their revenues their business ethics have changed drastically and even small value purchases are a minefield. Their dispute...

    Alarm to show if fridge circuit looses power?

    Both my upright fridge freezers have a standby light plugged into same socket so if the circuit they are on trips we know to reset it. It has a 12v 7Ah SLA internal battery but it is loss of AC mains that triggers it. Internally I think the circuit goes AC to 12v DC and the light trigger is DC...

    connecting gas/propane/natural gas generator to all in one solar system through 12v input of the all in one system

    It has been used historically to power cars / trucks / buses in needs must situations, IE no access to processed hydrocarbons. That was before solar panels existed. So it depends on your objectives. The main downsides to me are the energy density difference ( a LOT of wood to process and 10x...

    connecting gas/propane/natural gas generator to all in one solar system through 12v input of the all in one system

    Oops - i was just talking about how to charge your LFP with wood gas. For solar you are better connecting that to an all in one so you can do MPPT thru all in one to LFP or mains AC to charge LFP. Engine > alternator > Lead acid and DC DC to LFP was just for wood gas to manage the wood gas...

    connecting gas/propane/natural gas generator to all in one solar system through 12v input of the all in one system

    Have never done it - i am only a paper tiger - i dont mean to avoid the answer but before you go wood gas route you first need to quantify fuel type, how you are going to reduce moisture content before you use it, how to sort the chips so they dont clog, whether you are going to manually shake a...

    RV Air Conditioner tripping inverter after start

    I ran a small chest freezer for 2 years no issues 230vac then it sat unplugged unused for a few months. Finally got around to buying one of those power outlet adapters that you can put a clamp meter on to meassure current. Plugged it into a mains extension cord, turned it on to measure inrush...

    connecting gas/propane/natural gas generator to all in one solar system through 12v input of the all in one system

    Wood gas - another of my future build plans ? The calorific value if wood gas is lower than propane and from what I read some generators are more suited to wood gas than others. Propane 14kWh / kg Wood gas depends on what wood and moisture content of the wood but ball park 1.6kWh/kg It means...

    Which app?

    I bought an 8S JK but have not used it yet. I ssumed it was built in bluetooth. When I scan the QR code on the front of the BMS it takes me to a Chinese site with videos and one shows phone app connecting via BT with no external BT module having been plugged in during the video.

    Freezer to Fridge Conversion: Good performance or shitty Freezer Selection

    F_CF and F_DCF chest freezer comparison helps me. I see how all AC vs DC diverge more as ambient temps increase favouring DC so I can see in my case with a freezer indoors in a long term power failure in Thailand (so mid 30degC ambient due to no aircon) the DC would truly stand out in terms of...

    Tiny House Truck Finished with Build process.

    Ahaa IC. If your existing one is 240v can you check output voltage and whether it is a combined AC DC and ballast or seperate ballast? If combined you would need a complicated control for the AC side but if ballast seperate then you can cut off the AC plug and provde DC input to ballast and a DC...

    Tiny House Truck Finished with Build process.

    Yes you can either buy one with the flow sensor as a package with the steriliser or buy seperate. They are cheap as chips. Depending on your flowrates if you need a bigger one just get an aquarium one. So long as it is stainless steel body for better internal reflectance. They all have DC...

    Lived 6 years in Perth, WA so I know the dry heat well. Absolutely ❤️ your build thread and your choices. Clearly you spent a lot of time researching before you started. Fantastic results and stealthy as it should be. I am a bit of a water filtration geek in terms of energy water conservation...

    Freezer to Fridge Conversion: Good performance or shitty Freezer Selection

    Many different perspectives on this. I joined this forum because it is geared towards a robust and safe build that avoids the system becoming an ignition source. In the fridge / freezer threads I have not come across discussions on considerations for their selection to avoid them too being an...

    Designing car system for road tripping/camping - 12V or 24V?

    If you go the ammo box battery route so it still fits behind a seat i am pretty sure you can fit close to 200ah 12v plus BMS and wiring, fuses, etc depending on which brand of cells you buy and carefully getting the correct internal dimensions of the ammo box before you buy everything. My 8 x...

    Ping pong solar panel

    Solar panels on a ping pong table frame, not playing ping pong on solar panels. Question is on PV panel grounding / lightning protection requirements if I have temporary solar panels not fixed to the house structure but connecting to an SCC and an inverter inside the house. No code in Thailand...

    Questions with my DIY setup and charging via Car

    Those 12v cigarette sockets are wired with thin wire so aside from a low amp fuse to protect the wire, even if you change fuse you will risk fire and also see a big voltage drop when trying to pull a large current. However, 500wh is small so you dont need a large amp charger. I also think a 30A...

    Designing car system for road tripping/camping - 12V or 24V?

    Also a flashaholic and now spend my money and time learning this new hobby. You can get 12v hairdryers about 180w or cordless hairdryers with more oomph that you can charge at lower amps. Also easy to get lower watt kettles, just longer to boil but end result the same. Even 12v kettles are...
