Seaward
Seaward is a British test equipment manufacturer, and the product here is a photovoltaic installation tester rated to 1500 V.
Complete PV commissioning needs more than a multimeter: I-V curve tracing, insulation resistance at array voltage and irradiance with module temperature so results correct to standard test conditions. Confirm the maximum system voltage supported, since modern strings exceed older instrument ratings.
The Seaward SOLAR UTILITY PRO is a high-capacity solar PV tester rated for 1500V and 40A, designed for efficient testing of parallel strings. It features a large sunlight-readable display, stores up to 999 records, and pairs with the Solar Survey 200R irradiance meter for comprehensive single-person testing.
