DC/AC Inverter 1500VA / 1200W

The OPUS Inverter system is a redundant, fault-tolerant system. Inverter system is an optimal solution when long autonomy time and long battery service life are required. Inverter system is compatible with several battery configurations. Inverter system fits in the standard 19″ racks and cabinets. DUAL inverters efficiencies are high, up to 90%.

The OPUS Inverter system has a modular construction. The inverter modules can be combined with static switch, manual bypass, AC distribution and 3-phase synchronization modules based on customer’s needs. Additional integration options include the advanced VIDI+ controller, temperature sensors and battery monitoring.
