Practical advice for solar power systems

A remote weather station runs on its batteries day and night. Fit a fuse or breaker close to the bank on the main positive cable. After many years of daily cycling, every solar bank eventually fades.

Why choose the Trojan 31-GEL

Here is the Trojan 31-GEL, a battery for solar power systems. Identical batteries in a bank age at the same pace. Installers buy batteries online by exact model to match their designs.

Among batteries for solar power systems, 102Ah is at the smaller end.

Your questions answered

Can a battery be stored before use?

Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.

What size is the Trojan 31-GEL and how much does it weigh?

Measurements are 329 × 171 × 245 mm, and it weighs 32 kg. Check the height under the bonnet or seat as well.

Is the Trojan 31-GEL suitable for a 12V system?

Nominal voltage is 12V and capacity 102Ah. Wiring two in series doubles the voltage, while parallel wiring doubles the capacity.

Before you order: a quick checklist

  • ✓ Grab a tape measure: 329 × 171 × 245 mm is what this case needs.
  • ✓ 102Ah sets how long the battery can power things with the engine off.
  • ✓ Set your charger to gel before the first charge.

About the technology: gel

Gel cells contain no free liquid that could spill. Gel batteries lose little charge on the shelf, which suits seasonal equipment. Do not equalise gel batteries.
