Seems to me like there are many different ACH systems, but perhaps the one referred to colloquially as ACH is specifically FedACH, the American system.
ACH is a US-centric term that seems to be used for both the general concept of netted/batched customer-facing interbank transfers, as well as the US-specific set of agreements, rules, participants, and regulating body that together implement one such network.
There are many national and international equivalents, but the linked Wikipedia page gets many of the examples pretty wrong, listing e.g. card acquirers/processors and central banks as examples for other such networks.
Direct equivalents would e.g. be SEPA Credit Transfer (but not SEPA Instant) and SEPA Direct Debit in the Eurozone or FPS (credit push only) in the UK.

Giro might be the other, possibly broader term for something similar:
