Specifications per Greaves Power's official "CPCB IV+ Genset Technical Specifications" table (Excel export titled CPCB IV+ Genset Technical Specifications_20.07.2023.xlsx -- dated right at the July 2023 CPCB IV+ mandate rollout), covering the brand's current CPCB IV+ line from 5 to 500 kVA in both mechanically-governed ("Mech") and CRDI (common-rail, electronically-governed) variants. At 100/125/160/180/200 kVA both variants are offered as genuinely different physical products (different engine sub-model, governor architecture) sharing the same kVA/kWe headline number -- modeled as separate rows disambiguated -mech/-crdi; every other rating in this table is offered in only one variant. Cross-checked via bore x stroke x cylinder-count vs. stated displacement for all six distinct engine families (0.51L/0.612L/3.66L/4.87L/7.31L/10.04L/16.8L) -- all matched exactly or within rounding. Ratings from 75 kVA up require DEF/AdBlue (ISO 22241, DIN 70070) for SCR aftertreatment; below that, DOC or DOC+POC only, no DEF system. The source states two enclosure dimension sets per model ("As per TA" [type-approval/testing configuration] and "Overall") -- this row uses the larger "Overall" figures. No noise dB(A), warranty, or price data is stated anywhere in this document -- left null rather than assumed. The 57 kVA rating's stated kWe (50) doesn't follow the ~0.8 power-factor ratio seen on every other row in this table -- recorded as stated, not corrected. 400 kVA and 500 kVA share the identical 12V14TAG31 engine and kWm/HP figures despite different kVA output -- a retuned/differently loaded configuration of the same block, recorded as stated, not treated as a data-entry error.
