ECI Nova Modular Inverters 48 Vdc 1.25 kVA

Nova ECI is a small modular inverter offering many opportunities to design a solution that perfectly fits your needs. The ECI technology offers both AC and DC inputs to provide a perfect AC power while reducing the number of power conversion (the module operates under normal condition with the AC input delivering a 96% efficiency)! In conjunction with the DC input, it provides an excellent AC backup solution.

From 1 to 32 modules, with several options available (manual external by-pass and AC distribution), the Nova ECI is also hot-swappable meaning a very easy and cheap maintenance. The modules are delivered with our new monitoring solution.

Applications

  • All business critical applications from 1.25 kVA to 40 kVA.
  • The module can be integrated into shelves to design 1 phase (230 Vac) or 3 phases (3×400 Vac) configuration with different power output.
  • We already designed 3 shelves configuration: 5 modules (6.25 kVA, 1 phase), 4 modules (5 kVA, 1 phase) with the monitoring included and 9 modules (11.25 kVA, 1P) with the monitoring.
