Ah vs kWh Explained
Amp-hours (Ah) measure charge; kilowatt-hours (kWh) measure energy. To convert: kWh = (Ah x V) / 1000.

In depth
That is why two batteries cannot be compared on Ah alone: 200Ah at 12V is 2.4kWh, while 200Ah at 51.2V is 10.24kWh - four times more.
Marketing often quotes Ah because it is a big number, but what matters is kWh, and then usable energy after depth of discharge.
Quick rule: always multiply Ah by nominal voltage before comparing prices.

Common mistakes to avoid
- Comparing amp-hours only and ignoring voltage, ending up with four times less energy than needed
- Discharging lead acid below 50%, which cuts life to less than half
- Picking a bank that does not match the inverter voltage, so charging fails or runs inefficiently
- Thin cable or a long run between bank and inverter, causing voltage drop and lost power
- Mixing new and old packs, or different capacities, on the same bus
Next step
Send your load list and required hours over WhatsApp, or use the on-site system calculator to size the battery bank and array.
Technical advice is free, and the recommendation is based on your real consumption, inverter voltage and installation location rather than on the largest battery in stock.
Frequently asked questions
Which is better, 200Ah or 300Ah?
Unanswerable without voltage; 200Ah at 51.2V holds more energy than 300Ah at 12V.
How do I compare prices?
Compute cost per kWh: price divided by usable energy.
