EMERGENCY. If you see / hear / smell smoke, fire, hissing, popping,
sweet/chemical odor, or any temperature alert above 150°F: hit the
EMERGENCY STOP button (exterior, rear-right corner, red/white decal). Then
CALL 911 if there is any fire / injury / smoke, and call Lightnin.
Do not open the personnel door during a fire — oxygen accelerates combustion.
Follow the Emergency Action Plan for full procedures.
For Cabling and Operation, Follow Industry Safety Guidelines.
Ramp the orange dial up incrementally, 30–50 A per step, to Target Rate
Turn off generator at 95% to avoid wasting fuel. Unplug Grid source so ThunderBolts begin exporting again.
Trickle charger can use one or two hot legs. 3‑phase charging only begins below 85% SOC; auto-ignores at 95%.
Load Shedding — Managing The Fleet When Walking Away
Leave ThunderBank On
Keep ThunderBolts in On/Export — excess power helps ThunderBank run longer
For units that are needed, load shed nonessentials — especially air conditioners
Turn off or unplug non-ThunderBolt units not needed
If a ThunderBolt isn't planning to be used, leave it On/Export and shed its loads — it can still provide power to the bank or other units.
If solar will be 0 (overnight, indoors, snow-covered panels), ThunderBolts can be turned off too — likely won't be enough power to export.

ON / EXPORT
Default for ThunderBank operation

Exports automatically when above Min Battery SOC
ThunderBolts temporarily stop exporting while the ThunderBank has another 3‑phase charge source, and will resume automatically. Safe to disconnect a ThunderBolt while it is exporting — anti-islanding tech drops the output.
ThunderBank — Turning Off (Moving Locations or Long Term Storage)
Unplug or turn off exporting ThunderBolts first (Can be Off or On/No Export)
3-position switch slowly through Charge (pause ~3 s) to Off

Troubleshooting (Quick Actions)
Overcurrent while turning TBank OFF. Almost always from not unplugging exporting
ThunderBolts first. Clear with Off → On → Off reset cycle.
Overcurrent / inverter fault at any other time.Don't reset — call Lightnin.
A blind reset can mask a real problem.
Screen glitch on control panel. Press the small blue dot in the lower-left of
the display to reset the screen. Inverters and bank are not affected.
Air conditioning struggling, compartment 100–120°F. Not a fire indicator. Call Lightnin
for service. 150°F+ → follow the EAP.
Temp Sensor missing in VRM. Sensor battery has died. Call Lightnin.
Alternator fault light on. Switch to OFF and call Lightnin.
Victron's fault logic: disconnect → wait 30 sec → retry 3–5 times → then either disconnect
from the fault source for 30 minutes or ignore the AC inputs entirely.
EV Charger
Level 2 AC charger, up to 80 A. The EV picks the charge rate, not the ThunderBank.
Connected to Legs 1/2 — often adds 4–9 kW/leg.
Extensive EV charging decreases ThunderBank runtime.
ThunderBolt Behavior (key reminders)
Exporting appears as a negative AC Input number in VRM (e.g. −1049 W).
Trailer takes a few minutes of automatic safety checks before reaching its normal export rate.
ThunderBank shows ThunderBolt power as PV Inverter in VRM and ESS Charging on Control Screen.
ThunderBolt should be exporting but isn't. Unplug and plug back in to restart safety
checks. If still no export, call Lightnin to diagnose.
ThunderBolt is exporting and shouldn't be. Move ThunderBolt switch to On/No Export
or unplug.
Air Conditioning, Solar, Alternator
A/C setpoint 80°F or less. Sensors ±5°F. A/C can still use the battery in
OFF position.
Additional Solar PV breakers at rear-left (near the ABC extinguisher) —
OFF before connecting or disconnecting panels.
Alternator switch (cab, left of steering wheel): leave ON by default. If the
indicator light comes on, switch OFF and call Lightnin.

168 A/leg is max battery charge (60.5 kW DC). Above that, surplus AC stays available for loads.
(100 × kW) ÷ 270 = Charge % per hour
Use the net charge or discharge at the battery, not AC In or AC Loads.
Negative kW = discharge.
