Selecting the right battery bank can make or break your solar system's ROI. Trojan offers versatile deep-cycle solutions that integrate seamlessly with modern inverters and charge controllers. Here's your guide to getting it right.

Step 1: Assess Your Needs

• Capacity: Calculate Ah based on daily kWh draw (e.g., 5 kWh/day at 48V = 104 Ah bank at 50% DOD).
• Voltage: 12V for small setups; 24V–48V for efficiency in larger arrays.
• Type: Flooded (cheapest, needs watering); AGM (sealed, portable); Gel (deep discharge, hot climates).

Top picks: T-1275 (12V, 162 Ah) for RVs; SPRE Series for premium gel performance.

Step 2: Sizing & Compatibility

Use Trojan's online calculator: For a 3 kW off-grid system, 8x 6V L16 batteries yield 6 kWh at 48V. Pair with MPPT controllers (Victron SmartSolar) for 20% faster charging.

Step 3: Installation Tips

• Mount in ventilated enclosures (flooded types).
• Series-parallel wiring: Equalize cables (<3% voltage drop).
• Add a hydrometer for flooded maintenance.
• Safety: Fuses, disconnects, and proper grounding per NEC 2023.

Maintenance & Longevity

Trojan batteries last 8–15 years with monthly equalizations. Avoid over-discharge below 50% for max cycles.

Incentives & Savings

2026's 30% ITC covers Trojan banks when tied to solar. Expect $1,000–$5,000 rebates via utilities.
