• The whole system is composed of rotten-proof components, not
  containing any oily lubricant and definitely environmental-protection
  without harm.
• Use the electronic power generated by solar energy battery plate,
  through steps of strongest power point following-up, alteration and
  control, to drive the direct current permanent-magnet machine of
  brushless non-position sensor or highly-active asynchronous machine
  to spur the highly-active water pump, to move the water underground
  up for drinking by persons and animals or irrigation.
• Lower than 180W, the effect of direct current permanent-magnet
  brushless diving machine is ≥ 80%; lower than 1000W, the effect of
  direct current permanent-magnet brushless diving machine is ≥ 90%;
  the stability of insulating resistance is ≥200MΩ.
• Over-current and over-pressure protection; thunder-proof protection;
  unfolding protection.
