Complete Turnkey Battery Backup System SolutionsMission Critical

SunWize® Power & Battery Power Online Systems provide continuous DC power with battery backup from an AC source. These fully integrated, weatherproof units convert AC primary power to charge a 12 or 24 VDC sealed battery bank while powering a DC load or an AC load with integral inverter option. Since the loads are connected to the battery bank 100% of the time, there is zero transfer time in the event of a loss of AC primary power. Various battery sizes are available to provide increased backup capability and improved filtering of the charger output. Systems are housed in a weatherproof aluminum style enclosure with passive filtered venting, a universal key lock and tamper-proof hardware suitable for pole, wall or optional tower mounting.
