The photovoltaic combiner box is IP65 protection grade and is suitable for outdoor/or indoor installation.
The installation location should meet:
- The installation location should fully consider the overall size and weight of the combiner box to ensure good heat dissipation and sufficient space for daily maintenance.
- Vertical installation, lt is forbidden to install this product up side down.It is recommended to use wall-mounted installation or pole-mounted installation.
- Ambient temperature -25°C~+60°C, altitude ≤3000m.
- Try to install them as close to the photovoltaic modules in series as possible to facilitate better convergence and reduce the use of cables.
- Avoid installing in a location exposed to direct sunlight.Excessive temperature will not only reduce the power generation of the system, but also affect the life of the combiner box.
