PS12030B: 3000W on/off grid ESS


12030B: 3000W on-grid and off-grid solar system  specifications

  • Good anti-deep discharge performance for on-grid and off-grid solar system
  • Electrolyte: gel state, no stratification of electrolytes in the battery cycle performance; low electrolyte density, slow to grid corrosion, long battery float life
  • Plate: radial rib design, the paste type active material, high-current discharge performance
  • Special gel battery separators for on-grid and off-grid solar systems, internal resistance, high porosity, and long service life
  • Excess electrolyte design: high carrier liquid electrolyte volume: filled with plates, partitions and the housing cavity to protect battery heat.
  • Less prone to thermal runaway
  • Colloidal tight-coated plate group to prevent material shedding
