Provide Protection for Off-grid photovoltaic power generator Energy Storage Systems
Clean energy products have always been an important part of GRL’s product system. Photovoltaic power generator has significant energy, environmental protection, and economic benefits, and is one of the highest quality green energy sources.
As an important part of the photovoltaic power generator system, the photovoltaic combiner box is an important product of GRL.
Customer Needs
Our Customer needs to provide solar DC combiner boxes for independent photovoltaic power generator systems. The solar DC combiner box energy storage equipment provides isolation protection to form a photovoltaic system that can operate independently.
Customer Challenge
The voltage of the photovoltaic power generator system has reached 1500V, which has higher requirements for the performance of the fuse. The power generated by the photovoltaic system needs to be boosted and stored in the energy storage system, which requires an additional fuse and DC isolator switch.
Solution
GRL supplied the solar panel combiner box and dc fuse box for this project.
Solar Combiner Box
GRL engineers use DC MCCB as the main switch, 40 amp DC fuse, and DC1500V fuse holder as branch circuit protection. Each PV combiner box adopts a six-way design and uses busbar connection clips to condense the current to the copper bars. The in-phase combiner box adopts stainless steel casing to ensure the temperature rise performance and protection level.
