10200W Hybrid Solar Inverter 48V MPPT On and Off Grid

Top of the STM hybrid range, model STM102248 delivers 10200W from a 48V battery bank. It is the choice where the 8200W unit runs out of headroom: boreholes and irrigation, workshop tools, hotels and larger commercial premises that want solar first, grid second and batteries overnight.

PV input is tracked by a single MPPT working across 90 to 450VDC, nominally 360VDC, with a 500VDC open-circuit ceiling and a maximum PV charging current of 160A. Keeping the string between 360 and 450VDC holds full-load tracking, and peak DC to AC conversion efficiency is quoted at 98% with power factor better than 0.99. Nominal AC output is 220, 230 or 240VAC at 44.3A, and grid feed-in is accepted from 195 to 253VAC at 49-51Hz. Loads split across two outputs: a main output carrying the full 10200W and a second rated to 3400W for non-critical circuits, with main load cut-off at 44VDC.

Installers use it for hybrid, on-grid and off-grid builds on farms and commercial rooftops.
