Off-grid site farm terms (Pcrit, Popt, local-first)¶
For SITE_FARM when modeled off-grid-first (solar + battery default; WAN optional):
| Term | Meaning |
|---|---|
| Pcrit | Battery-backed loads and controls that should stay up through normal WAN outages and short SOC stress—policy-defined list (water head, gateway spine, etc.). |
| Popt | Sheddable loads: extra RF, dense cameras, Starlink CPE, shop gear—cut first when SOC is low. |
| Local-first | Sensor → gateway → actuator and records paths work without internet; cloud is overlay. |
| DR-* | Stop rules on the farm (e.g. DR-1 metered network load vs battery)—see Off-grid infrastructure stop rules. |
