The invention relates to an octagonal battery-equipped array upright post micro satellite configuration. A satellite is designed into a non-equilateral symmetrical octagonal upright post structure; simultaneously, the octagonal configuration and the internal space design of the satellite are optimized; the satellite is partitioned into a platform cabin and a load cabin; a cabin section between a top plate and a middle plate is the platform cabin; and a cabin section between the middle plate and a bottom plate is the load cabin. Each cabin section is partitioned into three regions through a +Yclapboard and a -Y clapboard; according to equipment enveloping size, reasonable layout and arrangement are performed, the design of a main force transfer path is optimized and cable direction and the insertion space of an electric connector are fully considered, so that a compact and reasonable structural space can be ensured; simultaneously, an enveloping space provided for carrying rocket is fully utilized and the solar cell installation area of a satellite body is enlarged to the greatest extent.
