mZ Anderson invented a method of electricial connection commonly used by the solar industry with perhaps other applications.

Lithium IRON, vs Lithium ION, is this just a typo or is Lithium Iron a thing? ECO-WORTHY (2 pack) 12V 30Ah LiFePO4 Lithium Iron Deep Cycle Rechargeable Battery with Built-in BMS, 3000+ Life Cycles, Perfect for RV, Boat, Kids Scooters, Power Wheels, Tool Trailer, etc

Look Out, Relion has lifepo's that charge at -20 C (-4 F), there is a battery God after all! https://relionbattery.com/blog/lithium-battery-cold-weather

For the best connection I solder, do you? Why not?

You can say what you want about the moral compasses of the villains of the old west, but when government directs people to wear face masks to reduce spread of flu during a national panic, they are responsible enough to comply.

Don't forget to wash your panels now and then. Simple dish soap and water and a soft cloth for panels you can reach. For rooftop or pedestal mounted panels, if you can reach them from a ladder using a 10' piece of 1" pvc conduit with soft cloths tied on the end using soft twine, use plenty of...

Is "constant trickle" a bad thing when using a battery charger to long term maintain the charge of lifepo's?

The BMS shut my batteries down overnight because the battery voltage fell below 11 volts. There has been extremely low solar gain for the past few days and my batteries were already on the verge of shut down when night fell and the small current draw from my idling solar controller pushed the...

Greetings and salutations from the Southern edge of the Great North Woods of North America's East coast on the cold, wild North Atlantic! :cool:

CANCELLED It is heartwarming now that the Federali's have offered to provide free corona money, (we the people will get the bill for it in the form of national debt and program cuts), to businesses that have been disrupted by a flu panic-demic, how the sports entertainment industry, the...

just read the comments on the previous foam battery post, I'm not so excited anymore. Wish I could delete this thread but there's no deletion option. ://www.emarineinc.com/categories/Firefly-Battery

I had two,12 volt, 100 watt panels in parralel producing 16 amps and when I connected the same two panels in series to make 24 volts, it cut the amperage down to 8 amps, yet, less amperage is somehow supposed to be more amperage. How is less more?

Making the jump from a small beginner/learner PV system to a larger system that provides more power, without excessively wasting money along the way is a challenge, but with the right attitude it can be a fun challenge! ~ The next move I want to make is to add two more 100 watt solar panels for...

ONCE UPON A TIME, a crack shot bench technician with a gift for troubleshooting complicated electronic circuitry to component level said to me, "troubleshooting is 90% observation, 10% skill". As a mere mortal, I continue to find his statement truthful & comforting beyond words. I enjoy reading...

I just want a simple, big ole three pole, 100 amp switch that I can manually throw to switch between a 240 VAC generator and a 240 VAC invertor, nothin fancy. The output of a switch would feed a simple service panel with a hundred amp main breaker. A plain ole switch in a metal, outdoor rated...

Just a test to see if I can post photos and links, sorry this wasn't all totally about solar, blame it on my A.D.D.. ? Peace https://www.webstaurantstore.com/guide/600/how-to-calculate-amps-volts-and-watts.html

I was thinking ... when lifepo's are shipped and end up for periods of time in unheated warehouses, delivery vehicles, shipping containers and such in temperatures well below their rated tolerance, doesn't this mortally wound them? This ten year old forum time capsule on, "The effects of...

A friend loaned me this power bank and it's been really helpful in taking the strain off of a small solar system when I want too run a lap top, USB fan, radio and charge a few small things. As a beginner I am confused, this Polymer Lithim Ion battery bank is rated at 50,000 milliamps. If one...

If one has a 12 VDC inverter that produces 2,000 watts AC, how does one use the 2,000 watts AC output to to compute the DC current draw at full 2,000 watts output? Or does one not do that? Note: I know that about 90 watts = 1 amp current draw @ 120 volt AC, so 2,000 watts AC = about 22 amps...

The aunt's will love it.

My solar system is so efficient that it harvests full panel output even in total darkness. It has a 47 geekahertz opto isolated dynamic coupler which operates in the translucent light spectrum and loses no energy when transmitting power from the panels over fiber-optic cable. Sure it costs over...

Hold on to your hats, Solid State batteries could give lifepo a run for the money. https://www.androidauthority.com/solid-state-battery-978899/

The homestead was all abuzz upon the arrival of one out of six 160 watt panels purchased directly from Rich solar. Breaking the one dollar per watt threshold, the panels cost $140 each including the "free" shipping. FURTHER ADDING TO THE EXCITEMENT, the homestead executive purchasing officer...

When exorbitant motor freight charges add 1/2 again the cost of the item to the purchase price, wouldn't it behoove the manufacturer to offer a kit option for skilled, energetic, aspiring individuals that could be shipped in small boxes, thusly saving $250.00 +/-...

Because of geographic locale, climate & personal health situation, the opportunity to exercise can be challenging to infinite, varying degree. Move what ever you can every day, get outside when you can every day, if you smoke make it 1/16 less cig. every day, make healthy food choices as the...

Will and the moderators as well as other solar enthusiasts have been an invaluable resource for fact checking and information, THANK YOU. This is my hand drawn series parallel arrangement for a simple PV array that I have been working on as time allows. If it is incorrect and/or there are...
