Efergy Pro vs Meridian Elevate

View your production and consumption from anywhere! The Efergy Pro allows you to track not only your solar panels’ daily energy production, but you can also track your home electricity usage, how much energy you’re importing and exporting. This can save you a huge surprise when the electricity bill arrives! Without the information that the Efergy Pro provides, you can easily dramatically underestimate how much power you are drawing from the grid.

This application performs geometric line-of-sight (LoS) analysis between two elevated structures using a WGS-84 Earth ellipsoid model. It calculates the required Height Above Ellipsoid (HAE) along the straight-line path between two radio masts, accounting for Earth curvature using a mid-chord spherical approximation. Inputs: Mast A base elevation (HAE) and antenna height (AGL) Mast B base elevation (HAE) and antenna height (AGL) Geodesic distance between masts Interpolation position along the path Core computation: Linear interpolation between mast tip heights Earth curvature correction using: d(D − d) / (2Rₑ), where Rₑ = 6,378,137 m (WGS-84) Required HAE at any point along the path Outputs: Required line-of-sight height at selected distance Real-time interactive profile of Earth curvature, ground surface, and LoS chord Visual indication of relative position along the path The model is purely geometric and does not include terrain elevation data or atmospheric refraction. It is intended for engineering estimation of direct geometric visibility between fixed radio infrastructure points.
