The ES22 series is an advanced online-interactive uninterruptible power system that produces pure sine wave power; Unlike traditional UPS, the series provides very short transfer when blackouts occur, and zero transfer from AC mode to battery mode and vice versa. The ES22-10/15/20 / 30K SOL series, includes 2 charge controllers Solar with MPPT technology, this series provides a low harmonic output sine wave and a short transfer period when there is a power outage.
The series voltage regulation is similar to an online UPS; however, the series provides greater than 98% efficiency under normal power conditions. Two charging modes are provided: fast charge and trickle charge, to keep the batteries in top condition.
