Primax Galaxy Dual PV12000+ Max Off-Grid MPPT Solar Inverter
Model GALAXY DUAL PV12000+ MAX
Primax Galaxy Dual PV12000+ Max is an 11000 VA / 11000 W single phase off-grid MPPT solar inverter on a 48 VDC battery bus, taking up to 12000 W of PV as two 6000 W arrays across a 90-450 VDC MPP window. Two independent AC power sources connect and switch automatically, dual outputs handle smart load management, and solar charging reaches 150 A. A built-in current transformer sensor supports self-consumption applications, with a 2.8-inch colour LCD, external BTS detection, optional GFCI, rapid shutdown and AFCI detection, and parallel operation with 6 units.
