Seaward Solar Power Clamp
The new Solar Power Clamp is a clamp meter
capable of measuring AC and DC circuit power, in
addition to true RMS voltage and current, resistance
& continuity, diode check, capacitance, harmonic
distortion and power factor.
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 whilst the PV modules are connected to the inverter, giving an
accurate true RMS reading of the power whilst 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 on the PV system after
commissioning. If a PV 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
in the system.
Similarly, the presence of harmonics on the AC output of an inverter may indicate a fault within
the inverter. In addition to power and efficiency measurements, the harmonic analysis function
of the Solar Power Clamp can be used as a means of detecting faults within the inverter.
As PV systems have a lifetime of over 25 years, periodic inspection and testing is necessary to
ensure that they are operating efficiently. Most inverters have a lifetime much shorter than that
of the entire system and so require particular attention as part of system inspection and testing,
to ensure optimal system return on investment and power output.
