  • Post in thread: Wondering why're many people still building 12/24v system ?

    Going over 33 volts means your system falls under a different set of regulations in some places ( maybe not in some or all of the USA ) You may not be able to get insurance unless you pulled a permit and had it inspected. You may run afoul of local electrical authorities with a grid tie system...

    I could be wrong about the pill maybe I watch too many old movies In every spy movie there is a poison pill and somehow you trick the bad guy into drinking the poisoned glass and the good guy manages to board a train and escape to West Berlin
  • Post in thread: Is it possible to protect your Solar System against EMP?

    I used to do business with an old order Mennonite “uneducated religious extremist” Hardly Pacifists and generally charitable, deeply moral and their greatest concern are not about worldly things but rather doing things the right things that will allow them to enter the kingdom of heaven when...

    Early mornings I get up and wonder do I really need to pee or or is my prostate going to give me a hard time. Sometimes I get more gas that urine, no matter how hard I push... Sometimes I have trouble telling gasses from solids...

  • Post in thread: Class T vs ANL fuse

    Fancy stuff I had.... Past tense an old timey resistance bridge for doing leads wingdings and connections. I don't recall the resolution on the meter but it needed calibration from time to time and this was never done in a timely manner so when people tell me resistance figures as low as you I...
  • Post in thread: Stuff does not last forever.

    At least once a year you should cycle all your breakers Unloaded of course… Breakers don’t age out They wear out from hard use If hit constantly overloading a circuit they will slowly wear out The harder the use the more quickly they will fail Oldest breakers I deal with daily are sone...

  • Post in thread: Help with installing a DC fridge

    10 is plenty 12 might even be ok. Your goal is to keep the voltage drop under 3%. Assuming the compressor runs at a 4 amps or so Options could be to use a normal AC fridge and an inverter with a stand by mode. The costs of DC vs conventional fridge with inverter is worth running the numbers on
  • Post in thread: New Tariffs in the States

    The USA has the US dollar. Oil is sold in Dollars, most international trade involves a Dollar... This is because of the post war way things went and the US dollar was seen as honest. And its was an economic and political sledge hammer used to steer the world PAX Americana To this day I think...
  • Post in thread: Many here say that an alternator should not be connected to LiFePO4 and that one should use DC-DC Charger

    This is a Chinese electric vehicle range extender. Nothing like it on this side of the pond I am aware of and no venders of this style of generator charger. It uses a PM head so there is no need for field control. The voltage and current regulation is managed by a computer that monitors both...

    HA HA Coders When I was in school we had micro processors. I was trained on the Z80 and the 6800 and those required you to understand what was going on inside the black box.. Every generation of processor since has done the same thing as the one it replaced and it has done it with ever...

  • Post in thread: 24V DC wiring in the cabin worthwhile?

    I'm off topic and really want to apologize for this but I want to add some more about pressure lanterns white gas and low compression engines. I'm sure everyone here has heard of lead in gasoline. Back way back in the past gasoline was very hit and miss stuff. it was not refined to a very tight...

    I have trees that belong in Appalachia that no one here has ever seen this far north.

( big black...
  • Post in thread: AIO High Frequency Invertors. Warning They don't Have An Iron Core Copper Wound Output Transformer.

    There was a time when the chopping speed of inverters caused issues with motors in industry. The jagged wave forms caused voltage spikes and the motors had to be inverter rated, and considerations had to be made around cable terminations because of the spikes... ( radio guys will be familiar...

    How you end up developing a load shed system is up to you This is a LOGO There are some as cheap a 60 bucks if you shop around I used these 20 years ago to do simple jobs that in the old days would have required a lot of relays and wires and devices that in todays money would cost maybe a...
  • Post in thread: NiCad anyone

    There they are all in there glory shiny and new and not mine... Of interest is this also has been upgraded the batteries are larger than the unit replaced the new charger does not have a equalization button. New heavier duty DC rated breakers too. I hate to disappoint, for the most part these...
  • Post in thread: Many here say that an alternator should not be connected to LiFePO4 and that one should use DC-DC Charger

    Alternators are not good battery chargers for any application. The right way to charge a battery requires you to limit the charge current to a level the battery can except for its state of discharge. Alternator regulators try to regulate voltage only. Also your likely to smoke the regulator...

  • Post in thread: AWG considerations

    Free air tables can be confusing If it’s a manufactured cable with multi conductors Or armoured cable your rating will be lower than free air. Inside a battery box might not be considered free air You might have to derate based on ambient temperatures or heat generated in devices Lots of...
  • Post in thread: 24V DC wiring in the cabin worthwhile?

    No don't do that. Octane is too low ( maybe an Onan LK or CCK with 5:1 heads could deal with it but its a bad idea with other sets ) When talking pressure lanterns gas generator is the vaporizer that turns liquid fuels into gas through vaporization and thermal cracking. This gas is then mixed...
  • Post in thread: Refurbish process for forklift batteries

    Cant see the big chargers in this photo.... After a while motor crews get lazy and don't charge enough. After deep discharges the batteries get weak and are starting to sulphate. That's when they start calling about a dead loco on the track without enough power to get to a charger It seems to...

  • Post in thread: Massive Texas power outage

    It makes sense on a residential are when building new infrastructure. Personally I rather be on the ground working on a pad mount transformer than in a bucket truck working on a can. This is a really old combination of parts. As long as your under 5000 volts it’s relatively easy to do cable...
  • Post in thread: Let's fight about aluminum wire!

    They make aluminum split bolts for that application Best thing to do is use all the same metal. I like to pack split bolts with duct seal. Then wrap in cotton friction tape and top with a layer of layer of rubber or vinyl tape. This never gives me any trouble It’s air tight, water proof and...

  • Post in thread: Possible laundry solution

    BE REAL CAREFUL what you buy. Modern machines are very cheaply built and they designs have been made with a consideration towards low water use and efficient motors. This does not equate to a long life or even a good job washing. Your WP is probably a late model of the DD system. These were...
  • Post in thread: Sol-Ark 15K + Generator

    All the electronics and sophistication in the world don’t mean a dam thing if you don’t have the power to drive it You need about 2 hp per kw to run a small generator with good regulation and wiggle room for surges Typically you don’t get that today You typically need a minimum of about 2...
