FAQ

Q1. Can it work without a connection to the electrical grid?

Yes, a 12kW Off-Grid Solar Inverter is designed to work independently without a connection to the electrical grid. Off-grid solar inverters are specifically designed for standalone solar power systems that operate in remote locations or areas where a grid connection is not available.

In an off-grid system, the solar panels generate electricity during the day. The 12kW Off-Grid Solar Inverter then converts the DC electricity produced by the solar panels into AC electricity, which can be used to power appliances and devices in your home or business. Additionally, the inverter manages the storage of excess energy in batteries for use during periods when the sun is not shining.


Q2. How many solar panels are needed for a 12kW system?

The number of solar panels needed for a 12kW system depends on the individual capacity of the solar panels being used. On average, for standard efficiency solar panels with a capacity of around 300 watts each, you would need approximately 40 solar panels to achieve a 12kW system. 

Number of Panels= Panel Capacity (kW per panel) divided by System Capacity (kW)

The actual number may vary based on factors such as the efficiency of the panels, local sunlight conditions, and any losses in the system.
