Rytheric posted:I can charge the battery of battery powered power tools. I do have a weak sauce battery powered hand drill because the manual hand drill disintegrated before my eyes while I was drilling bolt holes for the rudder through plywood. I can not however power a corded circular saw. My current power system is 1380 watt/hr and my inverter is 1250 watt/hr. A circular saw is like 1400 watt/hr and would draw like 120 amps from my 12 volt system prior to transforming without considering loss. No thanks. If a 10 amp draw will tax your system too much, that means that we're in agreement that your current situation is woefully inadequate in regards to effective, reliable electricity supply, correct? What is the cheapest, easiest, most portable solution to the issue of not having a reliable supply of electricity? And just incase you missed the detail in Motronic's video, I'll also tell you that my circular saw, sawzall, and jigsaw are all cordless, and so were all of the tools of all of the carpenters in my company

A 10 amp draw won't tax my system a 10 amp at 120 volts will or 100 amps at 12volts prior to the transformer.

Rytheric posted:You literally missed the first sentence. 10 amps @ 120V is 1200 watts, which your inverter seems to be able to handle. Regardless, if you go with battery-powered tools, you can have a few batteries charging all the time and comfortably rotate them as needed. Most systems have one battery type that fits an array of different tools.

I love this thread. Also, ry, this is the type hand drill you need:  I made a planter box last year and mounted my security camera with a drill like this. I bought a new ryobi a little while back that is much easier to use, but its nice having a backup.

Deteriorata posted:10 amps @ 120V is 1200 watts, which your inverter seems to be able to handle. That is what I do when I use my power drill. I have multiple batteries charging for continuous use. The point I was making is yes my inverter may be able to handle the corded 10 amps watt wise. But I only be able to run it for an hour because my battery capacity is 1380 watts. But more importantly that would be expecting my battery to supply the inverter with 100 amps which is not safe nor good for my deep cycle battery. I wouldn't want to subject my battery to more than 50 amps. My inverter recommends a 60 amp fuse between it and the battery. To make effective use of a 10 amp corded one, I would need to get a second 12 volt battery and run them in series to up the voltage to a 24 volt system and to drop the current down to 50 amps.

Elviscat posted:You don't run saws continuously. Lol that was interesting, but super loud. I wouldn't run it continuously but I would run it long enough to blow the 60 amp fuse protecting my battery. I chose the 1250 watt inverter because my max expected load at the time was 600 watts and as a general rule of thumb an inverter should be twice the expected max load as a safety factor. The inverter itself can handle a spike up to 2500 watts so it has a safety rating for itself, but that doesn't mean it's safe for my battery.

The Door Frame posted:100 DC amps, we can ignore because there aren't widespread DC power outlets, hence the inverter The "outlet" my inverter would be connected to is my battery. The inverter draws from my battery. The max output of the inverter Is 1250w, but the max draw of my battery is 50 dc amps which is half of 100 dc amps my inverter would need to invert to 10 Amps at 120 volts for corded power equipment. I can use battery powered equipment, but I can not use corded power equipment. Which means I'm not shirking away from powered equipment because of a lack of power since I can use battery powered equipment. I just don't like the dust and noise they produce.

I've missed part of the conversation. Is the battery the truck battery? Because if it is you can just run the truck, then the inverter is actually drawing from the alternator which should easily provide 1250W.

My alternator is in the same boat. It gives 60-80 amps iirc. I haven't added the alternator to the charging system yet. Looked it up stock my alternator runs between 50-95 amps depending on the rpms. Idling is on the lower side. There is a 130/140 amp upgrade. Rytheric fucked around with this message at 03:36 on Feb 25, 2021 |

I can somewhat get that, but when I talked about my electric system I pointed things out initially and if I recall clearly and seriously as electricity shouldn't be taken lightly. And pointed out that I have a house battery and a vehicle battery (rv speak). But I realize that is still confusing because both batteries are in the vehicle and I realized that people aren't going to recall my electrical set up section because I can barely recall it and im the author, so I was hoping Groverbattery and Trukbattery would differentiate and help people remember which one is in the engine bay and which one is in my closet. Plus things are suppose to be entertaining. What's the point of anything if it's not entertaining.

I spoke to an engineer because I was genuinely getting a little frustrated that people were suggesting I power something that would in my mind potentially damage my battery. Apparently in this rare instance I erred a bit more on the side of caution. He said it wouldn't be a 100dc amp draw, but that its a terrible idea. I was under the assumption that operating above .4 to .5 the C of the battery would cause severe damage to the battery, but he said that using the battery would cause degradation and using it above .4 to .5 C would just cause more degradation. So it's not as bad as I thought. I still don't want to do it though. I didn't design the system to do that. I only designed my system to temporarily heat the bedroom at most, run electric blankets, to charge my batteries, and to run my sleep apnea machine not for running tools and that's all I'm going to use it for. I may charge a set of power tool batteries at most in that realm. Edit: changed 100 dc volt draw to the intended 100 dc amp draw. Rytheric fucked around with this message at 05:04 on Feb 25, 2021 |

Lol you typically don't stamp a phone a friend particularly if your intention is to use less current than tolerable. As a reference, I didn't ask my uncle the question, but my uncle is an electrical engineer and helped me select my inverter. I was only wanting a 750w, but he insisted and got the expensive inverter for me as a birthday and Christmas present.

Just wanna check something here, you do realize that automotive/rv/marine electrical systems run on 12v (barring 24v bullshit setups) and an inverter converts to 120v, right? How the gently caress did you get 100v out of either of those ends?

I was only correcting your math on the power draw. I wasn't expecting you to actually power a circular saw off a 12V battery. The larger issue is that your productivity with only hand tools will be extremely low. You're going to need a source of electric power other than the alternator of the truk if you're going to get your houses built before you die.

How the gently caress did you get 100v out of either of those ends? I meant to say amp draw in that one paragraph. The object drawing power is a saw drawing 10 amps at 120v or 1200w which is being supplied by the inverter. The inverter is drawing the 1200w from a 12 volt battery system which equals roughly 100amps from the battery system.
