Types of Batteries (Storage Units)

There are many battery types based on structure. The most common are: PB, Li-ion, and LiFePO₄.

• PB (Lead-acid) – same as car batteries. Suitable for solar systems only in UPS (backup) mode.

• Li-ion – suitable for solar systems. When used correctly, they cause no issues.

• LiFePO₄ – ideal for solar systems. They are non-flammable, have a high cycle life,
  but are more expensive.

• Battery Types in OFF-GRID / HYBRID Systems:

  Batteries are typically classified as:

  • LV (Low Voltage)

  • HV (High Voltage)

  These two systems are not compatible with each other – inverter selection must consider this.

  • LV batteries – low voltage, usually in the 12–48 V range

  • HV batteries – high voltage, typically in the 120–650 V rang
