Overview
About the Optima Series
Optima Series is the premium tier of the Energia Max range. Output power factor 1 means 6000VA delivers a full 6000W — no capacity lost to the power factor gap. A 160–276V input window holds full load, the inverter runs at 95% efficiency, and there is no power derating anywhere across the operating temperature range. Battery voltage is configurable from 192 to 240VDC and charger current is adjustable from 1 to 12A directly on the LCD, so runtime design is genuinely flexible.
