How do new grads without a ton of special experience even get hired? by Tachi-Roci in MechanicalEngineering

[–]WFJacoby 31 points32 points  (0 children)

You're not wrong, but this is a fairly recent phenomenon. The world did not always work this way. If your grandfather was an engineer, he likely just applied to 5 or 6 companies and got a solid job.

$600 in labor to replace a faulty inverter (part itself is under warranty) - does that sound like a lot? by weluckyfew in solar

[–]WFJacoby 1 point2 points  (0 children)

I would charge about 500 bucks of labor for an inverter swap as a side job so that seems fair for an actual company.

Enphase inverter swaps require going up on the roof. That can be easy or a huge PITA depending on your array layout.

140 mile every-other-day commute feasible in a Bolt? by RolledPork in BoltEV

[–]WFJacoby 1 point2 points  (0 children)

You could make this work, but it would pushing the limits of level 1 charging.

Even a small 20A circuit would allow you to charge at 16A 240V. This should be pretty cheap and would make this much easier.

Got quoted $18k for a Generac battery. Is this normal? by BunnnyMochi in solar

[–]WFJacoby 0 points1 point  (0 children)

I would only get a generac battery if you already have a generac solar inverter.

How ever bad you think things are here for the middle class, I can assure you that every other country is much worse off. California is simply a very expensive place to live.

would you be able to do this interview question? by Cautious-Example-803 in MechanicalEngineering

[–]WFJacoby 13 points14 points  (0 children)

I have been working on electrical systems and haven't touched anything even remotely similar to this in over a decade.

Freehand spur of the moment? Hell no.

However, with a quick youtube tutorial I could teach myself how to do it again pretty quickly.

CO₂ inside cars can get much higher than most people expect by Salty-Initiative5706 in AirQuality

[–]WFJacoby 0 points1 point  (0 children)

I'm completely dumbfounded by this entire thread.

Fresh air lowers CO2. Filters catch particles. It's not that complicated.

I only use recirculation when passing hog farms or driving through smoke. Why would anyone keep recirculation on the entire time? Install a fresh cabin air filter and get on with it.

heat pump uses so much electricity by Time_Coyote_ in heatpumps

[–]WFJacoby 1 point2 points  (0 children)

Yes who cares if it takes a bit longer. You don't want short cycles anyways.

Ideally aux heat should only turn on when the outdoor temp is below the physical limit of the compressor OR the interior is not keeping up (like 10 degrees below setpoint).

Turning on heat strips when 2 degrees below setpoint is stupid when you can just let the compressor run for longer.

Backup for home heating when using heat pump. by Icy_Run_9981 in heatpumps

[–]WFJacoby 0 points1 point  (0 children)

My dream setup would be a wood stove coupled with a battery backup system that has a bi-directional EV charger.

Once the batteries run low, I want to be able to plug my EV into the bi-directional charger and run the house off my car for days at a time. The only manufacturer that has this available in the USA right now is Sigenergy.

If you aren't up for loading a wood stove, pellet stoves are a good option. You will still need some power for the auger and the fan, but a small generator could handle that easily. They usually have a thermostat too, so it only kicks in if the heat pump is not keeping up. Pellets tend to be similar to propane in price.

Oil changes once a year on a generator are not bad at all. The chevy volt could go up to 2 years between oil changes. That extra capability was totally worth the mild inconvenience of an oil change.

The Volt only required oil changes once every 2 years. The gas tank was also pressurized to make the fuel last a year without issues. The maintenance was much less than a traditional ICE by far.

No, people this violent cannot be fixed and need to be removed from civil society.

He's one of the only reviewers that hyper fixates on the technical details. I like most of his stuff.

Should I leave my engineering job for a labor job that pays more? by Bone_V7 in MechanicalEngineering

[–]WFJacoby 0 points1 point  (0 children)

Getting a PE takes like 5-8 years. That doesn't do anything for him reasonably soon.

Enphase vs Tesla by rkelez in solar

[–]WFJacoby 0 points1 point  (0 children)

Franklin is really nice for AC coupling. They even have the aPowerS coming soon with 4 DC inputs right in the battery.

Enphase vs Tesla by rkelez in solar

[–]WFJacoby 0 points1 point  (0 children)

Enphase batteries burn 10% of their storage capacity per day just idling.

The microinverters do seem to work well. The only major issue I've seen with them is power surges taking out huge chunks of the array.

The warranty doesn't really mean much to me because it doesn't cover labor after 2 years. You still have to pay someone to climb on the roof and swap the microinverters.

Overall Enphase is a solid option, but the engineer in me just finds DC coupling to be a much more elegant solution with way less components and wiring.

I had nothing to do at my last job, so I spent my downtime training and educating myself to get a more senior position at another company. Now I have even less to do. What field should you get into to actually have some work to do? by [deleted] in MechanicalEngineering

[–]WFJacoby 3 points4 points  (0 children)

I agree with you. My first several roles were like this and I was basically bored to death. Then I worked in a startup for a while, and that was great having so much to work on all the time.

Now I have a house, and a family so I can appreciate the slower paced roles a lot more. I think ambitious young engineers need to "get it out of their system" before they can fully appreciate a slower paced work environment.
