Applications

Energy

Current, voltage, power and energy, with pulse inputs and analog signals to measure what is running.

Both ends are here: the electrical installation that draws power and the solar plant that generates it, from field diagnostics to continuous tracking.

The problem

Load shifts through the day, and harmonics, imbalance and losses only show up when measured over time, at the right point. At a solar plant, output depends on radiation and on panel soiling: without measuring both, you cannot tell whether a drop comes from the sky or from the panels.

The variables

Power quality: harmonics, imbalance and transients
Current, through Rogowski coils, clamps or split-core transformers
Battery internal resistance and insulation resistance
Global, diffuse and direct solar radiation; module soiling and I-V curves

How to choose

For diagnostics, use a portable three-phase analyzer with flexible coils; to watch a switchboard, a fixed meter with Modbus. A USB logger records one signal; multichannel loggers combine several, and some transmit over cellular, Wi-Fi, Bluetooth or LoRaWAN, with email or SMS alarms. For pyranometers, compare the ISO 9060:2018 class (A, B or C); silicon cell models respond faster but are less accurate under cloudy skies.
