Why operators move

Why operators move from lead-acid to lithium

Lithium costs more up front. Whether it pays back depends on site visits and the grid.

  • 01Less weight and space in shelters and cabinets.
  • 02No watering and fewer site visits.
  • 03Many cycles where the grid is unstable.
  • 04Remote monitoring of state of charge and faults.
