Trojan 31-AGM SV AGM Reliant · Solar battery 100Ah

Solar battery Trojan 31-AGM SV AGM Reliant 100Ah 12V

For off-grid photovoltaic installations and storage systems, the Trojan 31-AGM SV from the AGM Reliant range stores 100 Ah with AGM technology through daily charge and discharge cycles. It replaces the original battery without adaptation in off-grid PV systems with a 325 × 173 × 238 mm format: same 100 Ah capacity.

• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Optimised for daily charge and discharge cycles.
• Good tolerance to extreme temperatures.
• Long life on float and moderate cycling.

Will it fit your current battery tray?

It has external dimensions of 325 × 173 × 238 mm and weighs 30 kg. It uses 6 15 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

What the Trojan 31-AGM SV is for

With 100 Ah, the Trojan 31-AGM SV stores the energy from your panels for the night and cloudy days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 30 kg and 6 15 terminals.

The Trojan 31-AGM SV: AGM Reliant range and AGM technology

Within the Trojan catalogue, the AGM Reliant series groups the references designed for this use. The 31-AGM SV is the 100 Ah model of that family, with the same performance as its siblings in other sizes.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. In the darker months, check the voltage periodically and avoid full discharges.
