Off-Grid System Components

• Solar panels – sized for your worst-month (winter) production
• MPPT charge controllers – maximize solar-to-battery harvest
• LiFePO4 battery bank – 3-5 days of autonomy
• Off-grid inverter – 120/240V pure sine wave output
• Backup generator – for extended cloudy periods
• Monitoring – track production and battery status

Off-grid system design is critical—undersizing leads to power shortages, while oversizing wastes money. Our experts help you calculate your daily energy needs, size the array for winter sun angles, and design a battery bank with adequate days of autonomy. A backup generator provides insurance for the darkest winter weeks.
