How to handle power fluctuations with miners?

This is really getting frustrating, and I can't shake the feeling that I might be the only one dealing with this unless someone else from my country chimes in. It's been three days straight of struggling with these power fluctuations from the grid. Things are getting worse since my ASIC miner keeps shutting down randomly. Any miner pulling over 1500 watts in my place shuts off because of these fluctuations. Is there anything I can do to fix this? I have a solar setup that helps during the day, but once the sun sets, it becomes a nightmare trying to keep my miners running. Just last night, I thought they were fine, went back to bed, and a few hours later, they shut down again. I've never tried using a stabilizer since I'm not sure if it could handle the power draw from an ASIC miner safely. Plus, I've never seen anyone online use a stabilizer with ASICs in any videos.

You are on the right way, you need a stabilizer. In rural areas of Russia, where voltage is often unstable, miners use these types of stabilizers. I've given examples for a single-phase and a three-phase network. https://resanta.ru/odnofaznyj-stabilizator-elektronnogo-tipa-s-cifrovym-displeem-resanta-asn-5000-1-c/ https://resanta.ru/trekhfaznyy-stabilizator-elektromekhanicheskogo-tipa-resanta-asn-150003-em/ Find an equivalent in your country. The stabilizer operates in the 140-260 volt range, meaning that in this range, the output will be a safe 220 volts for your ASIC in a single-phase network. However, if you experience power outages, you need a UPS.

Flaky mains usually trip the PSU's under-voltage protection, so the miner just dies and reboots. It's worst at sunrise/sunset when your solar/inverter hands off and the line sags for a moment. A 1.5 kW rig at 230V is around 6.5A. A 10-15% dip spikes current and many ASIC PSUs say "nope". You should isolate your mining device from the power grid with a UPS and/or a hybrid inverter that always outputs a steady voltage. Size this at least 2x bigger than the miner's wattage per unit.

You need to use a stabilizer that's specifically designed for the equipment you're using. Some have more power than others. Choosing the right stabilizer is the best option. Another good practice is to ensure that your home network is properly configured and installed to avoid overloading circuits. Also, check that you have adequate circuit breakers for the ASICs' power consumption. Everything can influence network stability.

Power outage is not a problem, I've gotten used to that and I don't need UPS since my inverter is capable of switching from grid to solar or vice versa when one is down, thanks for your helpful replies FP91G, I know that stabilizer are built for such things but I wasn't sure it's safe for asic miners, thanks for clearing that doubt. The Stabilzers you dropped are not available in my country, the manufacturer/brand is very suited for Russia consumers only, so I will have to find a brand that's available for my own country only or maybe I can buy from Amazon and ship it into my country.

Depending on your country or region I think you can install a mini step up transformer and a stabilisers circuit like others mentioned. Another alternative I've seen some persons apply is use a solar powered inverter system where you don't even notice power fluctuations and even when there's a power outage from the main grid, you'll not notice the switch to the inverter power immediately. The major problem is mining wares draw a lot of power depending on your setup and setting up a solar system that can power them can be relatively expensive depending on your region also.

Main point to keep in mind is that when sizing ANYTHING electrical is that you must NEVER have a constant long-term load exceeding 80% of what the device (or wire) is rated. This applies to wiring, circuit breakers, stabilizers/UPS's, ect. The short form is to take your miners' maximum power rating and add 20% more then pick a stabilizer rated for at least that power, preferably substantially higher. eg for a miner rated 3,500w the stabilizer should be rated for at least 4,200w.

Keep in mind that a good safety margin should always be left, ensuring that equipment never operates near its limit. This increases wear and tear and exposes the equipment to potential power surges. Any electrical equipment or installation can have a stabilizer, whether for mining or other types of use. Therefore, in highly unstable locations, the installation of stabilizers should be considered, not only for mining, but for the entire house and all electrical equipment.

This is exactly what I did, it will be stupid of anyone to buy a stabilizer that's the same wattage as the asic miner, there will be a big problem for sure if anyone tries this, even a non techy person should know this, but thanks anyway I appreciate your quality opinion. I've got a 15KVA relay wall mount style stabilizer and this calculation is based on my asic miners I have running presently right now, I am in the range of 10,000 watt power consumption for my available miners, so I believe I am good this way, shipped and on the way, thanks for your contributions everyone.

I've already written that this leads to more serious problems. Hot ASIC chips are immediately left without cooling, which leads to chip degradation. Simply put, the chip will fail faster. ASICs are unforgiving of this kind of error.

I actually disagree about the 80% safety number 70 or 75% is better. I have run dozens of models of asics. Almost everyone runs over its wattage rating. Ie lets take the s21 it claims to pull 3500 watts. so 3500/.80 =4,375  and you are safe. But if the room is hot it can pull 3700 to 3800 watts which means 3800/.80=4,750  is the better number and 4750 watts is more like 3500/.735=4,761.905  so a .735 or 73.5% is safer. Also and this is complex lets say your 240 volts drops to 190 volts depending on the quality of the voltage regulator it may only boost back to 212 or 220 volts. I prefer to use a 5000 watt regulator for a 3500 watt machine.. which rates to 70percent I have not had a failure with any 70% derate the unit below with some proper rework inside is good enough to run a 3500 watt unit even if power drops to 190 volts https://www.amazon.com/Norstar-DAVR-5000110-transformer-Automatic-Regulator/dp/B07169Z3XX/ref=sxin_17_pa_sp_search_thematic_sspa? but if you do not know what you are doing do not open it to alter the wiring a bit.

It too so long to get my stabilizer   but it's finally here Few days after, grid power becomes stable I guess they fixed the problem after making some complains but I will still install this stabiliser because of another day, it doesn't take very long for same grid problem to come back, can't waste weeks shutting down my miners again. Cheers

When you hook it up show us a few photos Thanks for the followup so far.

This is a voltage issue on your end, and you'd better consult a local electrician to resolve it.

it is more likely the grid lacking stability. I have run at places where 220 would drop to 190 one to two times a month for an hour at a time. Not much I could do about as it was the backup power test of NYC NASDAQ exchange which was routed to the substation where our mine was.

If you don't understand (how to handle it), it's best to contact local electricians to come and conduct an on-site inspection.

It isn't necessary for you to find everything on Google or YouTube. Any other country's or area's power system wouldn't work like your area's, and most probably you haven't found the solution for that reason. Unless someone else faces similar issues, or any YouTubers haven't faced similar issues, they will not create any tutorials about it. So you have to find the solution yourself. Good to see you post the problem here. Hopefully you will get your solution from here. I have worked abroad as an electrical foreman, so I believe I will have a solution for you. I am not sure how many ASIC mining setups you have. First of all, you need to separate the power circuit for ASICs and your household. Then ASIC load won't affect your household. If you use a stabiliser, then most probably you have to use a separate one for each setup. You have to buy a stabiliser according to your setup demand. So you will be out of problems. But for all the setup, if you have voltage issues, then you may use transformers as well. It will always stabilise the voltage; it doesn't matter what the power transformer is receiving.

Explain why a transformer is used in the home. In my country, a transformer is an industrial piece of equipment that steps up or steps down voltage. For example, a transformer produces 220/380 volts from 10,000 volts. If the transformer is overloaded, the output voltage will be lower or fluctuate depending on the load on the transformer. I remember about 30 years ago, my parents used an old voltage stabilizer that had a transformer. It made a loud humming noise at home. Modern voltage stabilizers are based on transistors and control boards.

That's right, a transformer and a voltage stabilizer are not the same. The voltage stabilizer I use is this one and it works perfectly. SONAPA SPM-3000VA

The electrical system can flactuate based on how the power grid is setup and what equipment is being used even such as grid switching storm issues and even motors starting can cause this flactuations. Did you know the voltage SAGs lasting les then 100 millisecods can end up costing millions of dollars damages resulting in outages lasting several minutes. Installing a piece of equipments called the SAG RIDE THROUGH DEVICE can significantly reduce inrruptions in your electrical system. UPS systems is great for back up power. Computer loads and even power conditioning but they required batteris costly oversizing in rush current and a high maintenance cost. That's why SAG RIDE THROUGH devices are great solution for larger essential loads.
