1. Are both 6.5KW and 10KW models compatible with 120V/240V systems?

Yes. Both models support split phase 120V/240V output, allowing compatibility with a wide range of residential and commercial electrical equipment.

2. Can users upgrade from 6.5KW to 10KW in future system expansion?

Yes. Many off-grid system designs allow users to expand system capacity over time, depending on battery configuration, solar array size, and installation requirements.

3.What is the advantage of a split phase off-grid inverter?

A split phase inverter can provide both 120V and 240V output, allowing it to power standard household devices as well as higher-voltage appliances such as air conditioners, pumps, and power tools.

4. Is the OSP Series suitable for North American power systems?

Yes. Split phase output is commonly used in North American residential electrical systems, making the OSP Series compatible with many local applications.

5. Which model is better for larger energy demands, 6.5KW or 10KW?

The 10KW model is more suitable for larger homes, workshops, or systems with multiple high-power appliances, while the 6.5KW model is ideal for standard residential off-grid applications.
