Meatrol Mi550 vs Fluke 1736/1738: Three-Phase Power Logger Comparison
The Meatrol Mi550 and the Fluke 1736/1738 are portable three-phase power and energy loggers used for load profiling, energy audits, solar PV sizing and power quality screening. Both log voltage, current, power, power factor, energy and harmonics up to the 50th order, and both meet IEC 61000-4-30 Class S. The practical difference: the Mi550 is…

Power Factor Formula: How to Calculate Power Factor (With Examples)
Power factor is the ratio of real power to apparent power: PF = kW ÷ kVA. A reading of 1.0 means all supplied power does useful work; below roughly 0.9–0.95, most network operators start charging penalties. To calculate it, measure real power (kW) and apparent power (kVA) with a power analyser and divide. The Invoice…

Using logged energy consumption data to plan solar and backup power system
To size a commercial solar or backup power system correctly, log the site’s actual consumption — per-phase power, peak kVA, and power factor — for at least one full operating cycle. Measured data exposes phase imbalances and true peak demand that utility bills hide, preventing undersized inverters and overcapitalised arrays. Designing solar and backup systems…

Solar Self-Consumption Analysis with PVSyst: Importing and Analyzing Consumption Data
Solar self-consumption analysis is essential for anyone looking to maximize the value of their solar PV system. As feed-in tariffs have declined and the value of exporting electricity to the grid has dropped, analyzing and optimizing how much solar energy you use on-site has become crucial.

The significance of energy load profiles for designing efficient photovoltaic systems
A load profile is a record of a site’s power consumption over time, typically logged at 1- to 15-minute intervals for at least a week. In commercial solar design, it shows when and how much power is actually used, so the PV array, inverters, and batteries can be sized to real demand instead of estimates….
