Whether you need a sophisticated solar  (wind, air, water) setup wired into your main panel with smart inverters and Wi-Fi and or Bluetooth control and remote diagnostics, or just a few of those one size fits all batteries to keep the lights on during a bad storm. Lithium Solar can easily meet all your expectations and provide you with the best solution and let you keep some of that hard earned green by going green. I only source class A cells and top of the line BMS systems so you the consumer can benefit the most.  If you want even more savings, like up to 48% off new, I have several hundred 18650, and I can get thousands more, that I can build to any scale that you want.
