I want to find a way to use two old home theater subwoofers with failed amplifier boards. I also have two Jensen XDA92rb car audio amps which run on a typical 12v car battery, around 240w rms @4ohm (600w peak) which matches well with the subwoofers. I have a 24v 200ah lifepo4 battery charged...
I'd like to know what these people are comparing the electrodacus sytem to.
Some do not like that the electrodacus system (sbmsX) is limited to 24v and 8s. This is due to the chip he designed the entire system around.
It may be frustrating to have someone say "ignore MPPT" after decades of it...
I found a local supply for a few of these panels but when I searched reviews I find only the same videos I watched years ago. Stion 135 with a frame is the model. I realize the company is gone.
Can anyone comment on expected vs real solar output? Longevity? Issues?
Thanks,
Maybe not exactly what you are after, but I often use a charger made to charge various size lipo batteries. ISDT is the brand, and mine does 8s at 20a. It also has a "DC bench power" function that can use anything over 12V and can downconvert as low as you want or upconvert to 30v at 10a. They...
Check electrodacus's site as he just posted some info comparing 3 x 255w and 3 x 260w panels on a sbms0+dssr50 vs 6 x 260w panels on a sbms+Victron 50a mppt charger. It looks like on a sunny day the mppt was around 5-6% more efficient. It will be interesting to see his results on overcast days...
I just wanted to add I've been using 16 of these 32650 premade packs for over two years as a 24v system and they've worked well. I haven't checked the capacity lately but haven't felt the need. My guess is batteryhookup stopped selling them because they sold out, but I'll maybe have to read up...
MyK3y, is this inside your house or underneath and outside?
I was leaning towards water for storage because I can keep a tank in my basement, then use a dc water pump to circulate hot water through some pex tubing. I was going to mount the pex tubing underneath my wood floor, then attach...
Since they are 7ft long and cheap, I've actually considered replacing an old fence with these things. Any chance they could be securely/safely "mounted" vertically with some 4x4 or 4x6 posts on either side?
Thanks for posting the videso and sharing.
It isn't specifically designed for hooking up to a grid, is probably what I should have said. I would lump rv, boats, vans, into the general "off-grid" category, because while they could be charged with mains power at times, they aren't connected to the grid. I should have been more specific...
There is a local supplier of some damaged 235w 60 cell panels. The "damage" seems to be mostly the broken front glass. MC4 connectors seem intact. I will be able to visually inspect each one, and I'm sure I'll at least check voltage, etc. If someone has a great checklist of things to look for...
In 20yrs the solar output on every panel will be 0w? People wishing for 455w output on day one or at 20yrs just haven't read about the technology. There is always the possibility they could all be destroyed in a tornado, etc. Or they could still be outputting 50-60% in 40yrs, which I'm not...
Thanks. I know they have a ton of videos on youtube updating people, but I haven't heard much about their newer 6kw and what it can do that is different other than the physical layout being almost the same as the 12kw.
I wonder if it still has this voltage sag you mention. I got a powerjack...
Am I not wrong in thinking "when conditions get worse" almost nothing you can do will get you much heat? Doesn't that account for a very small percentage of total heat production?
It sounds to me like most of the time 1000w of panels will give 600-900w of solar. Those bad times you are talking...
I'll admit pouring my dehumidifier condensate into the toilet tank after a flush.
I'm less excited about using it to shower or wash my hands or drink because I've read too many in depth discussions of what these companies coat their radiators/coils with.
Not the way I'm proposing it isn't, but if you can't access underneath the floor it would complicate things for sure. My issue with air sand is you have to still somehow move the heat around with fans. I have just heard too many people gushing about radiant floor heat and I've liked it the...
I have an sbms120 in use. I'm curious why you decided to use a dssr20 and a separate mppt controller? I'd rather have two or three dssr20 or a dssr50 that takes up no space at all. I've been more than happy with the built-in charge controller of the sbms120.
I also have a u-shaped midea 8000btu...
I bet the reference to 12v and 24v panels is because when you look at prices of used panels, 60 cell solar panels can be 1/4 the price of 36 cell solar panels. I had my heart set on these cool, thin, all-black glass solar panels only to discover the open circuit voltage would require equipment...
I was about to suggest having something like a pi zero with camera attached close by so you could view the LCD over a network, but I guess you'd have to add some type of servo to adjust the buttons to get out of the screensaver mode of the lcd... ha.
Did you ever get anything more elegant than...
You can use a DC to DC Boost converter to raise voltage. You can use a DC to DC Buck converter to lower the voltage. Neither are 100% efficient, but it is done quite frequently for various reasons. Many circuit boards input 12v or 19v, but then down convert to other voltages to safely run...
I'll throw out some ideas and you all can laugh.
If you already need water storage, solar panels could mounted on top of some "IBC totes" that are used to transport liquids. Filled with water those won't move. Not for everyone.
I have a long (12ft) pallet for some reason, and it would be...
Not Likely,
There are hybrid hot water heaters which use heat pumps, and one benefit is they dehumidify the space they are in. Could be helpful in your situation or maybe not.
Another thought is in the summer you may have more solar power than you know what to do with, and throwing that...
Much depends on the exact layout of your home, but my plan is to eventually build an island of solar power in a carport or detached garage next to my house. There is no power in that location now and adding it requires a decent chunk of work and cost anyway. Putting solar right there saves on...
Santan was pretty good with me on accepting my offer. It was less than they list on ebay by a decent amount. Not positive where I will get more when I do. I need 60 cell panels for my electronics, but the 72 cell seemed to be a better cost/watt ratio for a long time. And if you can utilize...
I had a longwinded explanation typed out, but the short answer typically is, "get one more panel." I am aware this is often not available or affordable on other solar setups which have panels in series to get higher voltages. This flexibility is another advantage for the Electrodacus system...
