Version: 1.1 Prepared For: Field & Deployment Teams Platform: Raspberry Pi / Linux Tool: mbpoll / pymodbus 1. Purpose Complete reference for the SRNE ASP48120SH3 three-phase hybrid inverter over Modbus RTU: what can be READ, what can be WRITTEN, and the tested...

Validated Modbus register map for the SRNE ASP48120SH3 three-phase hybrid inverter, verified register-by-register against the live Nansana unit, including a grid-off / grid-on transition test on 2026-07-27 that resolved the previously-unknown registers and cor...

Purpose and scope This page documents the SRNE ASP48120SH3 safe settings write feature (story #53): the ability to remotely change a bounded set of inverter parameters over Modbus, with every write guarded, verified by read back, and never retried. It records ...

Date: 8 August 2026Attendees: Aaron Tushabe, Dansturn Kimbowa, Hillary ArindaDuration: ~2 hours 5 minutes 1. Nansana Pilot & Battery Backup The Nansana battery backup system is now live and billing has proceeded without major issues. Initial operation indica...

Summary We self-decoded the SRNE ASP48120SH3 settings registers (V1.7 protocol PDF + a live read-scan of the pilot inverter, firmware v925, 2026-08-09). The key result: time-of-use charge/discharge scheduling is implemented and writable, even though real-time ...

Authoritative page for NFE's role in the IEEE Smart Village meshEMS / Street-EMS initiative. Compiled 2026-08-10 from the Element room "Smart Village Energy Interest Group" (full history back to 2026-04-24), the ISV Dev Kit BOM sheet, isv.wiki, and the Rev B/...

Traceable explainer: how metering data actually moves, where DLMS/COSEM, OBIS, Modbus, MQTT and HTTP each sit, and how NFE's live CHINT registers map to the OBIS standard vocabulary. Compiled 2026-08-10. Companion to "NFE metering strategy + Glen Street-EMS"....

How the NFE inverter-monitor decides what to alert on, and the 2026-08-10 hardening pass that killed the nightly "Battery low" noise and closed several alert-integrity gaps. Source of truth is the code + ADR-012 in nfe-modbus-energy-logger; this is the team-f...

The plan to turn on time-of-use battery arbitrage on the Sezibwa/Nansana SRNE inverter (logger issue #67): charge the battery from the grid off-peak, discharge it to the load at peak, using the SRNE charge/discharge SCHEDULE registers written through the guar...

Problem When the site runs on battery (grid outage, typically evening or night), switching on a large single-phase load such as a heater or fan trips the inverter off until the load is removed. This causes an outage for the whole site. Evidence (2026-08-11) Pe...

Data provenance Underlying data: the aggregate meter meter_100 plus the 10 customer sub-meters, over 2026-03-19 to 2026-08-10, from the modbus energy-logger archive (sources: pi-direct and nextcloud-import), i.e. the pre- and early-OpenEMS period. Load basis i...
