Solar Panel Combiner Box for Dual MPPT Inverters up to 600V. 2Ways In. 2Ways Out

Solar Combiner Junction Box for 2x MPPT Input Off Grid & Hybrid Inverters - 600Vdc

Why do I need a combiner box? First of all for protecting the installer and later the users. During the installation of solar panels or when maintenance is required, the strings of solar panels carry up to 25Amps at voltages that are lethal for humans (up to 550Vdc).

Before a high-voltage PV array is connected to the inverter, it is important to install fused terminals and DC isolators that will give adequate protection against short circuits and surge voltages.

The 2/2-600V is a waterproof combiner enclosure with two fully protected independent solar strings and two independent outputs. The PV input with a maximum 25A, 550V goes into the box and the same strings is connected to the MPPT charger of the inverter.
