13 years of experience in measuring and controlling photovoltaic installations!

Since 1982 Seaward has been manufacturing electrical safety test equipment and distributing it throughout the world.

Since 2007, the solar branch has been developing and producing the PV150, 200 and PRO products, which are measuring devices and IV curve plotters specially designed to meet the expectations of solar power plant operators.

Sundays Data System partner Seaward !

Thanks to our recognized expertise and acquired through our supervision activity, we have been able to integrate Seaward products into our range.

Seaward have placed their trust in us and we are proud to count them among our partners!

PV current clamp - AC / DC inverter tests

The Solar Power Clamp can be used when installing a PV system to ensure that the inverter is working properly and to measure its efficiency rate.

> DC and AC power is measured directly from each side of the inverter in seconds using the Seaward Solar Power Clamp.

> The power clamp simply clips onto the cable to measure current and the in-line connectors provided can be used to measure DC voltage while the PV modules are connected to the inverter, giving an exact accurate RMS reading of the power and efficiency of the inverter.

> In addition to power and efficiency measurements, the Solar Power Clamp's harmonic analysis function can be used as a means of fault detection in the inverter.

MC4 T-Cable Set for Seaward Clamp

The cables connect to the clamp and pick up DC volts while the clamp simultaneously reads DC amps.

Thanks to the reading of currents, voltage and DC power allowed by this tool and thanks to the same reading on the AC side, the efficiency of the inverter can be checked.
