40L-100L equal 100L-300L Solar 72V DC Photovoltaic Water heater
Features:
  1. 1st Solar PV DC water heater in the world and extremely efficient
  2. Incredible 10 Year Warranty!
  3. Does not require an inverter or any other equipment
  4. Water Heater functions like a Thermal Battery storing energy throughout the night and remains hot for your morning shower
  5. 72V DC+220V AC at the same time
  6. AC power just a backup, even in winter nearly no need for grid electricity
  7. 2 grade higher than the best water heater standard on Energy consumption and heating insulation each 24 hours temperature loss less than 8 degrees!
  8. Nearly no need for grid power in winter only with 400w-600w solar panels for different areas.
  9. Efficiency Data: 2 levels better than the best top standard.
  10. 24H Intrinsic energy consumption coefficient only 0.46.
  11. Intrinsic energy consumption coefficient Level 1<=0.6;Level 2<=0.7;Level3<=0.8;Level 4<=0.9;Level5<=1.
  12. The hot water output rate is as high as 94.8%; the highest level 1, is only more than 70%.level 2 should be more than 60%.
  13. Power consumption is only half of the traditional electrical water heater if only use grid power.
  14. No need to worry about water leakage anymore!
  15. No need to waste minutes of cold water before hot water!
  16. Constant water temperature for more comfort!
  17. Easy installation/Safe usage!
