Seaward Solar Power Clamp
 
The Solar Power Clamp is especially designed for installers and technicians interested in power measurement and analysis on AC & DC systems and carrying out diagnostic checks.
 
In order to ensure the maximum yield from a PV system, it is important to check the efficiency of the conversion of DC power generated by the PV modules to AC power fed into the electrical installation. Efficiency is determined by measurement of both the voltage and current on the DC and AC sides of the inverter and using the measured values to calculate the DC and AC power.
 
Alternatively, the DC or AC power can be measured directly on either side of the inverter in seconds using the Seaward Solar Power Clamp. The Power Clamp simply clips over the cable to measure current, and the supplied in-line connectors can be used to measure the DC voltage while the PV modules are connected to the inverter, giving an accurate true RMS reading of the power while the system is operational.
 
The Solar Power Clamp can be used when installing a PV system to ensure the inverter is operating correctly, or for maintenance and troubleshooting after commissioning. If a system isn't generating the expected level of power under known irradiance and temperature conditions, this may indicate a fault with one or more components. Furthermore, the harmonic analysis function can detect faults within the inverter by identifying harmonics on the AC output.
 
As PV systems have a lifetime of over 25 years, periodic inspection is necessary to ensure they operate efficiently. Most inverters have a shorter lifespan than the system itself and require particular attention to ensure optimal return on investment and power output.
