What battery type is best for solar storage in Nigeria?

Lithium Iron Phosphate (LiFePO4) batteries are the best choice for Nigerian solar storage. They last 10-15 years (vs 3-5 for lead acid), charge faster, discharge deeper (80-90% usable vs 50% for lead acid), require zero maintenance, and work well in Nigerian heat when properly ventilated. While LiFePO4 costs more upfront (₦250,000-₦800,000 for 100Ah-200Ah), the longer lifespan and better performance make them cheaper over time.

How long can a 200Ah battery power my house?

A 12V 200Ah battery stores 2,400Wh (about 1,900Wh usable with LiFePO4). This can power: basic lights (50W) for 38 hours, a standing fan (75W) for 25 hours, a TV (100W) for 19 hours, or a fridge (150W) for 12 hours — but typically you run multiple items simultaneously. A typical evening load of lights + TV + fan (200W total) would last about 9-10 hours on a fully charged 12V 200Ah LiFePO4 battery. At 48V, multiply runtime by 4.

What is the difference between 100Ah and 200Ah batteries?

A 200Ah battery stores twice the energy of a 100Ah battery at the same voltage. At 12V: 100Ah = 1,200Wh, 200Ah = 2,400Wh. The 200Ah costs roughly 60-80% more (not double) making it better value per watt-hour. It also means fewer parallel connections in your battery bank — simpler installation and better reliability. For most Nigerian homes, 200Ah is the sweet spot; 100Ah is suitable for small apartments or single-room setups.

How do I maintain my solar batteries in Nigeria?

LiFePO4 batteries need virtually no maintenance — just keep them in a ventilated area away from direct sunlight and rain. Lead-acid batteries require more care: check water levels monthly (top up with distilled water only), clean terminals to prevent corrosion, and never discharge below 50%. For all battery types: install in a shaded, well-ventilated space (Nigerian heat reduces lifespan), avoid placing on bare concrete (use a wooden pallet), and check connections quarterly for tightness.

Can I connect multiple batteries together?

Yes, you can connect batteries in series (increases voltage), parallel (increases capacity/Ah), or a combination of both. For example: two 12V 200Ah batteries in series = 24V 200Ah (ideal for 24V inverters). Two 12V 200Ah in parallel = 12V 400Ah (longer runtime at same voltage). Always use identical batteries (same brand, model, age, and capacity) when connecting them together. Mismatched batteries will degrade each other and fail prematurely.
