Solar Battery Lifespan and Warranty

In depth

Three things cut real life short: high temperature, repeated deep discharge, and charge or discharge current above the rating.

Warranty terms are stated with each product and follow the store's published warranty policy, covering manufacturing defects rather than misuse or incorrect wiring.

Keep the datasheet and the inverter settings you used - they are the first things requested in any warranty claim.

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.
