Hi I am working at research company in Osaka, Japan.

We are currently help our client researching about the current process of high-strength bolting at construction sites. Marking bolts is generally done with a pen with special ink, but they are considering developing a stamp-type product to reduce the workload of workers. For this purpose, we would like to talk to people who actually do bolting at construction sites. If you could cooperate with us, it would be great if you could DM me then I will share more detail. It is really hard for us to find the candidates, we would appreciate a lot if you could cooperate with us!

Below is a detail of the project.

Requirements

• Working in the US on a Highway/Bridge job
• Have experiences using Bolt Markers at construction sites

Summary

• Project: 60-90minutes online interview surevy.
• Topic: The current process of high-strength bolting at construction sites
• Payment: 100USD Amazon Giftcard via email

This is the process:

1. We will ask you a few screening questions. (I will send you a Google form URL via DM)
2. If you are selected, we will schedule an interview.
3. Interview.

I’m looking forward to hearing from you!

We had a Sungrow battery system installed. In theory it's their minimum 9.2kwh battery backup, but we're consistently only able to get about 3kwh out of it from overnight loads (generally 250-600 watts) Is the energy return efficiency through their inverters really just this bad? I'd expect some loses, but not 60%.

Can anyone connect me with a solar electricity vendor in Argentina? Looking to deploy a remote solar-powered industrial system around Rio Gallegos, Santa Cruz and I would like a second opinion on my sizing. I understand it is a challenging area for solar.

I am currently in the process of researching solar power companies to transition my home to renewable energy or Setup in NJ. I am enthusiastic about the prospect of harnessing solar power to reduce my environmental footprint and energy bills and to get of the grid. However, I have heard concerns from some homeowners about solar companies that install systems, but then resell the generated energy to others, diminishing the benefits of energy independence.

I am reaching out to this community to inquire if anyone has experience with solar power companies that respect your energy autonomy and do not resell the generated energy to third parties.

Hi all, this is a small solar power source I have tried to install in an open field, those battery set each contain x2 90ah car battery in series (because those x2 solar panels produce 24v) My problem is that whenever I checkk on batteries they have about 2070% considering what control chargers show are accurate (I check on batteries usually around 13:00 to 18:00), I rarely see if all batteries are at 100%, what can be the problem here, did I have any mistake on how I wired or installed equipment or x2 of 330w panels are not sufficient for this amount of batteries here, as load I have x3 of 24v led lamps and a refrigrater with size of 11ft with A++ energy consumption (197kwh/yearly) Somedays I see that my batteries couldn't keep refrigrator on till morning even, and since we are getting close to winter I feel it will get worse even Whenever I checked the amps delivered from panels to control charger, it was about 13 amps ( I usually checked those numbers on digital screen of control charger and around 14:00 to 17:00) Any help and suggestions is appeciated

Note: I am thinking to get a cheap optimized 12v inverter instead of that old 24v inveter and parralel all batteries for 12v, while I am thinking to buy x2 24 to 12v converter to add them before my control chargers

Is transmission and interconnection engineer position hard ? I’m an intern just started ..can someone answer

Envision a rooftop that not only shields you from rain but also saves you money and helps the environment. Rooftop solar systems, categorized as commercial and residential, have an inspiring tale to tell.

Commercial - Rooftop Solar Solutions: These are akin to solar power giants, gracing large buildings, factories, and offices. They act as solar energy superheroes, generating substantial clean power for businesses, resulting in significant savings.

Residential - Rooftop Solutions: These are the solar systems tailored for homes, akin to your cozy neighborhood hero. Despite their size, they offer substantial savings, helping homeowners cut electricity bills and embrace eco-conscious living.

In both scenarios, the concept is straightforward: harness sunlight and transform it into savings. Whether you're managing a business or unwinding at home, solar power presents compelling financial and environmental advantages.

im new to this sub and have zero experience with solar power. i come with 100% ignorance on the topic. so please be kind.

i live in a country where in the recent weeks, electricity has been going out almost on a daily basis. sometimes it's for 5 minutes, sometimes for a couple hours. it's almost planned i think. not sure what's going on. either way, not important.

i work remotely, and my question is, what type of specs should i look for when purchasing a solar powered generator? keep in mind, this is only to retain my job so only my laptop and router will be plugged in. nothing else. i need something quiet since i will be on calls and something that will last a couple hours. i went on amazon and saw some from $200 - a couple grand. im not trying to spend more than 300. i saw online that people buy the actual generator and then some panels separately? i thought the generator would have its own panels. i guess it depends on the model? again, super foreign to this tech and open to any tips

What factors inspired you to use solar lights?I am just curious about that.

And I am very hesitant to use solar right now.Please give me some suggestions.

Hello,

Looking for a setup that will allow me to run a small cooler (not mini fridge, just a small electric cooler) and small things like phone and tablet charging at night. I'm starting a business that will involve longhaul trips and sleeping outside/ in car to watch over livestock. Wondering what a good setup would be for continual power for small cooler and nightly phone and small gadget charging? Oh, and 2 looping cameras. (Think the cameras can run off car battery but jic)

Thanks in advance!

Hi all, hopefully you can provide me some advice on something I want to achieve.

I have the following PV equipment: -

PV panels – 12 x Longi LR4-60HPB-365M

Inverter – Solax X1-G4-Hybrid 5M

Battery – Triple Power (Solax) T-BAT H5.8

What I want to do is charge the battery from the grid if the p/kWh is below a certain limit (let’s say 10p/kWh), if the battery level is below 100%.

Our electricity usage is fairly low now, so in the summer the battery rarely drops below the minimum set limit level of 10%. It also pretty much always serves the whole demand during the higher price period of 4pm-8pm.

But in the winter, it’s a different story. Sometimes the battery hardly charges. So I’d like to charge the battery from the grid when it’s below a certain price level, and use that during the day / evening instead.

I am told that the Solax inverter and battery “work with Octopus”, but I can’t find very much information on what that actually means. I was hoping I could link my Octopus account and Solax account, and tell it what I want it to do.

I’m no computer expert, so was hoping it would be that easy when I saw that it “works with Octopus”.

Do any of you clever chaps know what I need to do to make my battery charge on cheap grid energy, and then use that when it’s more expensive?

Thanks

A door-to-door salesman from U.S. Renewable Energy gave a sales pitch to my parents, and now I’m trying to confirm this company’s legitimacy. I’ve already instructed my folks to cancel their follow-up appointment and assume that, even if legitimate, the business model is likely to use the home as collateral in a risky contract (equipment financing, utility payment pass through, etc) that they should avoid.

My parents are unsure whether or not their currently installed solar panels are working, and if they are working…how to measure their output (or reconcile against their SDG&E utility bill). What are some good resources to get them started answering these questions? Their inability to answer these questions is what made them even consider a door-to-door sales pitch in the first place.

Talk about the replacement and use characteristics of solar street lights.

In recent years, society has progressed rapidly. We have no time to sigh that before, things are gradually changing now. Even the street lamps that we often see in our daily lives are changing in style and use. The traditional street lamps we used before have all changed. They have been slowly phased out and replaced with emerging clean solar street lights.

Solar street lights are more energy-saving than traditional street lights. The electricity they use comes from solar resources. For solar street lights, it is a zero-consumption and zero-pollution solar road light. In addition to saving electricity, solar street lights have an appearance,which is beautiful and elegant, and is integrated into every area of use, making the installation of solar street lights also form a landscape.

Solar street lights are simple to install, save energy, are environmentally friendly and low-carbon. Solar energy-saving street lights have many advantages when used on urban roads. They reduce energy consumption, make urban road lighting more energy-saving, brighter and more efficient, making people's travel more convenient and safe.
