Luyuan Technology - Pretty simple to view their website or to enter or register with Alibaba https://szluyuan.en.alibaba.com/index.html Amy Wan is the main contact (you can find her email address in a search of DIY Solar forums). I don't know of other "Amys". Jenny Wu from Docan has had good...

I despised, hated my propane tankless water heater and 10 year experience and finally ripped it out after going solar. Reasons are: needs to be vented which created a large 6" hole in my basement wall and cold air in winter was difficult to keep out. Plus the vent required electricity for the...

The Instant Pot vs regular pressure cooker are like night vs day in energy use due to direct and insulated "in the pot" heating vs transfer heat from the induction plate and energy loss to ambient air temperature and especially due to it's safety, as well as convenience, due to the Instant Pot...

I did not find switching the freezer thermostat for a fridge thermostat to be a good solution. Finding parts was not easy here and then there was the main problem of removing the freezer thermo coupler and the difficulty of routing in the replacement refrigerator unit. That can be a real PITA to...

Have you done the math? You could help by giving the exact specs of both devices that you are referring to. I personally have no idea what the booster pack has for power potential, but my guess that its designed for short high amp output. Like a car battery, it is not designed for long deep...

There are NO DUTIES to pay when importing from USA or China. Only the usual sales taxes which you will pay anyway if you go pick them up yourself. The most I could have saved is the $60 US + sales tax on $60 that UPS charged me to act as the broker to get them through customs in the middle of...

“ If the Sun ain’t shining then what ? It is my experience DIYers then turn to Propane / Gasoline / Diesel ." If the sun ain't shining I use my 100 Ahr LiFePO4 battery to run my 24V to 120 AC small home until the sun / daylight starts again in the morning. Yes heating with anything is costly...

It seems to me, that it is assumed, that one will have direct sun for the entire work day? As well, unless it actually is sunny and you moved the truck or the panels once very hour to keep the sun in a direct line and the panels at the best angle for the time of year, then you would still need a...

What is the Growatt idle consumption (nothing being powered)? These All in One /AiO inverter/charger/ MPPT charge controllers can consume quite a bit of battery power over night and during cloudy days. Personally, I'd go with a low consumption Low Frequency inverter/charger and a separate MPPT...

Go to the Resources section of this forum and read about how to put together and Energy Audit and then present that here. Until you do that, no one knows which appliances you plan to use, what their power draw is at what voltage and for how long you will use each and every appliance, light bulb...

Welcome Kenny! But what you say here and on your website is very vague and no different than what I've read and personaly received from GSL and Felicity and others that have exactly the same products and hype as you do. I've also received worse misinformation and broken agreements and lack of...

Also go to the resources section here and read the article on Low Frequency vs High Frequency Inverters. Have you done an Energy Audit yet? Do you know what it is? Also found in the resources section. You are throwing around high inverter numbers but you provide no numbers on how many watts...

I also use the Ink Bird lined above, now going on 2 years and it has been great, but it does use 110-120V power, so I run my inverter 24/7 which only uses 16 watts. The Inkbird uses very little power and the chest freezer after start surge only uses 50 watts. With the Inkbird, I set the High...

Inverters handle appliance loads. Size the inverter for your required loads plus a % more 25-50%? Charge Controllers handle energy from the solar panels into a battery. Some inverters also have a built in charge controller, many do not. Some with built in charge controllers, like mine, do not...

Richard is correct IME, but I bought my set up from Canada 18 months ago when info was scarce, options in Canada were very few along with retailers, Covid was blocking shipping from USA or travel to USA. DIY options and info were few. My finances were, are low. My 15 year old lead acids were...

Yes heat does reduce panel output or efficiency as does the panel's angle, which if the angle is fixed, will be a compromise for the time of day and time of year for the panel angle and for your location. Meaning, fixed panels will rarely meet their advertised specs unless all variables are...

No other "comparable" seller with variety of choices that I've found. There is a seller of a built 280 AHr battery in northern Alberta, Grande Prairie, on Kijiji that has decent prices, given that he does all the build work, top balancing, capacity testing etc. and his cost also includes...

I use Midnite Solar brand. Also try a search for "combiner boxes", which is usually what the breakers are mounted into. I've seen threads on those before. You also don't mention your country as that may have a bearing on equipment and codes?

Yes a heat pump water heater could be nice but not yet on my poverty level pension. It will take many many months to save for and I'm not sure that for my needs at least, it would be worth it vs another solar panel or 2? Lots of previous threads on hot water heating methods to read through, but...

Are you heating or cooling this 1200 sq ft space with the solar power? Otherwise the size of the cabin has nothing to do with how much solar you need. Your info is extremely vague. Go to the Resources section and read about doing an energy audit, do it, and then post again with any questions?

But looking at the Docan website, they do not offer a "Powerwall". The do offer 1 - 12 volt 100 Ah battery pack from what I could see. In my dealings with Felicity, they out and out lied to me. Meritsun seems unknown here until just recently and it looks to me that their products look exactly...

Wouldn't it need to be attached to an altermator, AC or DC, which would cause resistance and so remove the free spinning you see and which now has no load / resistance. Find, cost out and attach a weather proof alternator may not be affordable or doable. What about bearings and or slip rings...

Wow, I live extremely comfortably with many appliances, gadgets, tools, etc with a 24V, 100 Ahr LiFePO4 battery and a 4 kW inverter. Baking 2 loaves of bread at the moment, computer on, other devices charging. Now if only I had the cash you put into the BattleBorns and will be putting into...

You will need more sustained wind than 5-8 mph (minimum double or 12-15 mph for a few watts) and a wind turbine with large blades and clear foreground of 100+ yards and a minimum tower height of 50+ feet, otherwise, the physics of wind won't have enough power to turn your blades to turn your...

I would would look for a LOW FREQUENCY Pure Sine Wave INVERTER like a used, "old" Trace or Xantrex SW4024 (4,000 watts nominal and which handle much higher Surge loads than cheaper modern high frequency inverters). The newer versions are called Schneider or Context? These older Trace or Xantex...

List your appliances, list how many watts each uses (= the load in watts) and list the length of time that each appliance load will require power. List any known "appliance surge" (search the forums on surge load threads if you are not sure what that is. This is called a basic "energy audit", it...

I wish you could make sales and shipping options to Canada easier. I hate it when a website says to call or email for more info. I tried emailing two different times, one reply took days for vague info not answering my request and the second attempt received no reply. I gave up and eventually...

I've been using Android 10 with a low to mid level Motorola smartphone and which is several years old. I've used the JK App for the last 8 months with the JK_B2A24S20P BMS, with zero issues since activating the BMS and installing whatever that initial version of the app was. The app has been...

I'm not sure what you mean by "vague", as all the info seems there, but there is quite a bit of it, lots of settings that can be made. It took me quite a few readings and figuring out the input settings buttons before it started to make sense. In my user manual - - read page 42 = Control Panel...

Probably. An inverter doesn't know or care what battery type supplies the DC current to invert to AC. Also, the inverter is a bit flexible with the supplied DC voltage to invert out to AC. Your DC voltage however is more applicable to the battery charger, some of which are built in to...
