Let's walk through a complete example: Daily power usage: 2,000 Wh. With LiFePO₄ at 80% DoD: 200 Ah ÷ 0. You'd need at least a 12 V, 250 Ah battery bank.

A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems. For more accuracy, divide the load by the actual battery voltage and adjust for inverter efficiency (typically 85%).

Grid-tied solar dominates the market for good reason: With 2025 system costs ranging from $2. 00 per watt installed and federal tax credits of 30% through 2032, grid-tied systems offer the fastest payback periods (6-10 years) and highest returns on investment without requiring.
