Trojan 22-AGM · Solar battery 50Ah AGM

Solar battery Trojan 22-AGM 50Ah 12V

For off-grid photovoltaic installations and storage systems, the Trojan 22-AGM stores 50 Ah with AGM technology through daily charge and discharge cycles. Its 228 × 139 × 204 mm make it the exact replacement for the 50 Ah battery fitted as standard to many off-grid PV systems.

• Compatible with common MPPT and PWM controllers.
• Maintenance-free in off-grid installations.
• Low self-discharge during the darker months.
• AGM: faster recharging and better cycle resistance than a conventional battery.

What the Trojan 22-AGM is for

The Trojan 22-AGM is designed for off-grid photovoltaic installations and storage systems. Size the capacity so as not to discharge more than 50% daily and you will greatly extend its life. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 18 kg and 15 terminals.

Size, terminals and hold-down of the Trojan 22-AGM

It has external dimensions of 228 × 139 × 204 mm and weighs 18 kg. It uses 15 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

Technology inside the Trojan 22-AGM

Within the Trojan catalogue, the 22-AGM is the 50 Ah model designed for this application.

AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

Trojan: the maker behind the 22-AGM

Trojan Battery is the world reference in deep-cycle batteries: golf carts, cleaning machines, aerial platforms and solar systems rely on its T2 technology and longevity. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Manufacturer's warranty

The Trojan 22-AGM comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

Care and maintenance

Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
