Inverter Size: 1000W (with 2000W surge), 12V compatible Adding Load and Battery Expansion If you plan to add more batteries or higher AC loads in the future, select a modular inverter and oversize your solar system slightly to accommodate growth.
Rule of Thumb: The inverter’s rated power (kW) should align with the battery’s capacity (kWh). - A 5 kW hybrid inverter typically pairs well with a 5–10 kWh battery. - Oversizing the battery can lead to underutilization, while undersizing may limit performance. Internal Link Suggestion: Learn more about Hybrid Solar Inverter vs Off-grid Inverter.
The size of a solar inverter is crucial because it determines how much energy can flow to your home and battery at any given time. More specifically, the inverter ensures that enough energy can flow from your solar panels to the grid and load or if installed with a battery, from and to the battery.
Example: If your home consumes 20 kWh/day, and you want backup for 6 hours, you’ll need roughly a 5–7 kWh battery system. Your inverter and battery must work seamlessly together. - Rule of Thumb: The inverter’s rated power (kW) should align with the battery’s capacity (kWh). - A 5 kW hybrid inverter typically pairs well with a 5–10 kWh battery.
