SunWize Series X 60 watt Power Online System
SunWize Series Y 600 watt Power Online System
SunWize® Power Online Systems
For continuous loads of 1-1000 watts
Available power supply is paramount for system networks such as microwave and cell repeaters, Wi-Fi and WiMax networks, and RTU/SCADA. Critical loads must remain operational during power outages and when utility power is not available 24 hours, 7 days per week. To address this reliability requirement, SunWize developed a utility-based solution with battery backup for outdoor applications. How does this solution differ from traditional uninterruptible power supply (UPS) systems?
What does the system provide?
Power Online Systems provide continuous DC power with battery backup from an AC source. The weatherproof units convert AC primary power to charge a 12, 24 or 48 volts DC sealed battery bank while powering the DC load or an AC load with an inverter. These systems are ideal for applications using bank switched street lighting where utility power is only available while the lights are on at night and not at all during blackouts. The daily blackout cycle can be as long as 14 hours in summer months due to extended daylight hours. Power Online Systems ensure power is available 24 hours each day and provide up to 5 days of backup power during power outages.
How does the system work?
Upon loss of AC primary power, the battery powers the load with zero transfer time since the loads are connected to the battery bank 100% of the time. A Power Online System uses a grid-powered battery charger to charge a battery bank. The battery can be 12, 24 or 48 volts DC. The charger is sized to operate the load and maintain enough reserve power to ensurethe battery can be fully recharged from complete discharge within 24 hours. Since load and battery sizes vary, systems can be configured from as little as 45 watts to as much as 2 kilowatts of charging power. Backup time can be as little as 1 hour to as much as five days depending on the critical nature of the load. Standard configurations are 8, 24 and 48 hours. Since the components used are common to our photovoltaic (solar electric) power systems, they are proven for reliable operation in rugged outdoor conditions.
