  1. All the big solar panels, [300+ watts] made in the 10 years have bypass diodes. These greatly reduce the effects of shading. Have run panels in parallel and series in the same situation, and find not much difference in output. The bigger panels are a much better deal per watt, but are higher voltage and require a MPPT controller. Many charge controllers today will take 150 volts, and a couple 250 volts. Most home grid-tie systems run up to 600 volts in series, so it is now mainstream.
  2. Have had 6 of them for about a year, Not cheap, but probably the last house batteries I will ever buy and many advantages over Lead acid. Many inverters and converters can be programmed to charge them. Call Battle Born and they can tell you if you can use the charger you have. Biggest advantage is you can charge at 1C in bulk, till battery reaches 100% SOC, and of course can use the full capacity, so my six 100 amp/hr batteries at 180 lbs total, will more than equal the usable output of four 8d agm batteries at 640 lbs total, and take up less than half the space and charge 4 times faster. Only drawback is the second mortgage I had to take out to buy them
  3. If you run your panels series/parallel, should be about 80 volts nominal, so about 15 amps to the controller, so #10 wire is okay, if designed for that voltage. Have to make sure your charge controller will handle that voltage also.
  4. For me the very best feature of lithium ion, is the ability to charge at up to 1C to 100% SOC with no absorption stage. So if I have used 200 amp hours out of my battery bank, and I can get 80 amps from my panels, and 120 amps out of my inverter/charger, in 1 hour, I am fully charged. With my old agm batteries, that would have taken 6 or more hours. Of course, unlike Lead Acid batteries, lithium batteries never have to be charged to 100%.
  5. Thinking he made a typo.More likely outtahere has something like these. https://www.solar-electric.com/rec-n-peak-series-320-watt-monocrystalline-solar-panel.html?gclid=Cj0KCQiA5NPjBRDDARIsA
  6. Right, 100 watts, not unbelieveabe 1000 watts..
  7. I am impressed Carlos, not sure how it relates to solar power.
  8. Carlos, must be back in the day technology, no need for dumps or heaters etc to use up solar power anymore. Solar controller just opens circuit. No voltage, no current, no heat. I have 1500 watts, and even when batteries are only taking 10 or 20 watts, have no need to dissipate extra power.
  9. Most grids are multiple panel, so imagine much, much bigger than 10x8.. Just can not understand the 48 volts? Most big arrays are panels in series to up to 600 volts.
  10. Thinking that with present technology, a 1000 watt panel would be well over 200 cells and well over 100 volts. A buddy that installs grid tie, says a panel that big would be like 10' by 8'. and size and voltage would not make it paractial. Biggest panel I have ever heard of is 420 watts with 60 volt VOC and is over 6x4 ft, but they haven't been sold for a while.
  11. Love to see a 1000 watt panel, do you have a link to any manufacturers?
  12. I watched it too. The Chinese government appears to really back EV development. But, on the other hand, most of Tesla's Model 3 production is going to China now.
  13. Ran 4 of them for 4 years, still loaded tested them at 95% when I sold them. Bought for $400 each at O'reilly's, [on sale], [worked good for deep cycle use. [only brought them down to 60% SOC only]
  14. Went from a 2200 lb Samurai to a 3600 lb CRV and can tell the difference. Not so much in cruising, but sure can in acceleration.
