    MultiPlus-II 12|3000|120-50 2x120V 2. DESCRIPTION 2.1. 120/240V input and output, or 120V input and output (always 120V output when in inverter mode) The AC input can be supplied from a split-phase 120/240V source or a single-phase 120V source. When an AC source is available, the MultiPlus will feed through the AC to its output. The output will therefore mirror the AC input.

  • Page 6: Li-Ion Batteries

    MultiPlus-II 12|3000|120-50 2x120V The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries. The adaptive function automatically adapts the charging process to battery use. The right amount of charge: variable absorption time In the event of slight battery discharge, absorption is kept short to prevent overcharging and excessive gas formation. After deep discharging, the absorption time is automatically extended in order to fully charge the battery.
