Energy storage lock auxiliary contact

What are auxiliary contacts in IQ system controller?

In such situations, auxiliary contacts in IQ System Controller can be used to disconnect (shed) excess solar or heavy loads. In addition, low-priority loads with high power requirements may deplete energy storage. Auxiliary contacts can be used to shed these large loads to help maintain energy in the storage system.

What are energy storage systems?

Energy storage systems are made up of different components that all contribute to the function of the overall system. Benefit from our portfolio of PCB connections, connectors, and electronics housings that demonstrate our strong innovation power.

Why is no1/no2 auxiliary contact not energized?

NO1/ NO2 auxiliary contact is not configured. As a result, there will be a voltage drop across NO1/NO2. The contactor is not powered. Diagnosed by measuring AC voltage on the contactor coil. The contactor is not energized. Faulty wiring between auxiliary contact in IQ System Controller and definite purpose contactor.

Why do you need a power-to-X energy storage system?

Contact our energy storage expert, Dr. Rüdiger Meyer Batteries and Power-to-X concepts increase security of supply and enable consistent sector coupling in the energy supply industry. Phoenix Contact provides you with internationally certified connection technology designed to meet the high demands of energy storage systems.

Why do energy storage devices need a strong electrical connection?

Energy storage devices compensate fluctuations in renewable energy, thus guaranteeing a stable energy supply. For a huge range of applications, energy storage devices must operate safely, reliably, and efficiently. Resilient and durable electrical connection technology is necessary to satisfy these requirements.

What is an auxiliary contact?

An auxiliary contact can be used to intercept the “cool” wire from the thermostat to the air handler. The “cool” wire may also be called a “cool call” wire. Once this is done the IQ System Controller auxiliary contacts need to be configured to shed loads automatically in off-grid as outlined in the sections above.
