Midnite’s 1,000 amp battery combiner box is the ideal solution for high-powered systems with a large number of DC conductors. For example a large off-grid or battery backup system with several inverters and charge controllers will likely require a big DC positive and negative bus to combine all of the inverters and controllers for connection to the battery bank. The Midnite MNBCB-1000/50 battery combiner is the best solution we’ve found for large battery-based systems. There are plenty of conduit knockouts and breaker slots for installing a large number of battery conductors with overcurrent protection.

The Midnite MNBCB includes positive and negative 1,000 amp bus bars and this version (MNBCB-1000/50) includes a 1,000 amp 50 milivolt shunt which works with the SMA Sunny Island inverter system. Most other inverters (Outback Power, Magnum Energy or Schneider Electric) will require the MNBCB-1000/100 battery combiner.
