MidNite Solar MidNite Solar MNEDC250RT

Midnite’s MNEDC-RT shunt trip breakers are designed to work with the MNBirdhouse rapid shutdown system. When installing rapid shutdown in a battery-based system the inverter main DC disconnects need to be replaced with Midnite shunt trip breakers which are controlled by a battery disconnect module (MNBDM-24 or MNBDM-48 depending on battery bank voltage.) Once the MNBirdhouse disconnect switch is activated the shunt-trip breakers are going to disconnect, cutting off battery power to the inverter system. A battery disconnect module is required for use with Midnite’s shunt trip breakers.Note: using the MNBirdhouse without a disconnecting combiner will require the MNFAUX cable to work in place of the combiner box in systems where only the battery breakers are being disconnected. Add the MNFAUX cable when a Midnite rapid shutdown combiner is not being used with the MNBirdhouse.
