Dutch photovoltaic grid-connected protection switch
The GS protection measures the grid voltage and grid frequency and switches off the PV system via the integrated interface switches as soon as the switch-off conditions are fulfilled. The grid and system protection activates the interface switch. The interface switch usually consists of two electrical switchgear. As electrification accelerates, installers need to offer solutions that help homeowners maximize self-sufficiency, leverage dynamic tariffs and implement overload protection to avoid exceeding their grid connection limits. Protective and isolating switchgear equipment is particularly important and ABB offers a full range of these products both for circuits branched from photovoltaic panels, where the high direct voltages typical of these installations are. All new PV plants over 1 MW in the Netherlands will have to use a real-time interface to make their facilities better communicate with the grid operator starting from next year. Utrecht-based Withthegrid, has developed an interface that is compatible with a number of brand-name inverters.

Using a clamp meter to test a photovoltaic DC cable
This guide explains how to correctly measure DC current in PV systems, what to watch out for, and how to obtain reliable results in real-world solar applications. In a PV system, DC current is measured by clamping a DC-capable clamp meter around a single DC conductor. Traditionally used by electricians for measuring current without breaking the circuit, a modern clamp meter, particularly one with DC voltage. Unlike traditional inline measurements, a DC clamp meter allows you to measure current safely without disconnecting the circuit, making it the preferred tool for live PV systems. This helps determine the panel's efficiency and identify any performance issues. Testing is usually conducted under standardized conditions to ensure accurate results. You may also use an IV curve. A clamp meter is a clothespin-shaped instrument that can be clamped around a live wire in order to measure the current it's carrying.
