subcategory	high-voltage battery MODULE for a stacked tower system (96 V class)
variant_note	MODULE-level record. 96 V / 37 Ah / 3.552 kWh per module. Do NOT confuse with the tower system energy (7.10-21.31 kWh). Used only in the Tower T7-T21 series; the manual's successor part for Tower S3 is HV9637S and for Tower Pro it is HV9640, and per an ONSA Plus retailer note HV9637 and HV9640 modules cannot be mixed in one tower.

installation_notes	Manual prints the module dimensions as '(W x D x H, mm) 380x504x240'. NOTE this labelling puts 380 in the width column while the assembled tower is 504 wide and 380 deep, so the manual's W and D labels for the module appear transposed relative to the system table. Recorded verbatim; treat the 240 mm figure as the per-module height step (it matches the 200 mm-per-module enclosure step only approximately, so do not use it to derive stack height).
