Quick answer: 24V is best for smaller systems under 5kW or budget inverters. 24V lithium batteries are ideal for small to medium solar systems (1-5kW). They work with most budget-friendly inverters and offer a good balance between capacity and cost.

When to Choose 24V

24V systems are best for:

  • Small homes and apartments
  • Essential load backup (lights, WiFi, TV, fridge)
  • Systems under 5kW
  • Budget-conscious installations
  • Existing 24V inverter systems

24V Lithium Batteries FAQs

48V is more efficient for larger systems (5kW+) due to lower current and thinner cables. However, 24V is perfectly fine for smaller systems and has more budget-friendly inverter options. For most South African homes with essential load backup, 24V works great.
24V lithium batteries range from R15,000-R40,000 depending on capacity. A typical 24V 100Ah (2.4kWh) lithium battery costs R15,000-R20,000. For more capacity, consider multiple batteries or stepping up to 48V.
For most South African homes, lithium iron phosphate (LiFePO4) batteries are the best choice. They offer 10-15 year lifespan, 80-100% depth of discharge, and require no maintenance. Popular brands include Hubble, Pylontech, and Dyness.
Lithium batteries last 10-15 years (4,000-6,000 cycles). Lead-acid batteries last 3-5 years (500-1,200 cycles). Gel batteries last 5-7 years (1,000-1,500 cycles). The lifespan depends on usage, depth of discharge, and maintenance.
Yes, most lithium battery systems are modular and expandable. Pylontech, Hubble, and Dyness systems can stack multiple units in parallel. Make sure your inverter supports the expanded capacity.
