The series is a long backup type, line interactive, with pure sine wave output. Besides the backup time can be as long as your external battery pack can provide, we also put more protection in the unit. The protection for reversed battery polarity is provided in case of a wrong connection. While if battery polarity was reversed, the UPS just doesn't work without any damage; and it will work until the connection is correct. Smart battery management with two charge modes, quick charge and trickle charge, are provided to maintain the batteries in the best condition.
