OBO PVG-C1000K 110 PV Generator Connection Box 2x1 String 1000V DC IP65

Photovoltaic installations demand reliable, safe, and efficient connection of solar strings to inverters. The OBO PVG-C1000K 110 generator connection box solves this by providing a robust, pre-wired enclosure that consolidates two PV strings and feeds them to two MPP trackers of a central inverter. This eliminates messy field wiring, reduces installation time, and enhances system protection with integrated surge arresters and a DC disconnector.

Who is it for

This connection box is ideal for solar installers, EPC contractors, and system integrators working on residential, commercial, or industrial PV systems up to 1000 V DC. It suits projects where two strings need to be combined and connected to a dual-MPPT inverter, ensuring compliance with safety standards and long-term reliability.
