100Ah Solar Batteries FAQs

A 100Ah battery provides 1-3 hours of essential backup (lights, WiFi, phone charging). For longer backup or to run a fridge, you'll need multiple batteries or a larger capacity option.
Yes! You can connect batteries in parallel (same voltage, more capacity) or series (higher voltage). For example, 4x 100Ah 12V batteries in series-parallel gives you 24V 200Ah (4.8kWh).
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.
