Hit EMERGENCY STOP (or unit trips it automatically)
EMERGENCY. If you see / hear / smell smoke, fire, hissing, popping,
sweet/chemical odor: 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
At 95%, unplug Grid source or turn off generator — avoids wasting fuel and lets ThunderBolts resume exporting.
Trickle uses 1 or 2 hot legs. 3‑phase charging begins below 80% SOC, auto-ignores at 95%.
ORANGE DIAL — External Charge Rate Control
3‑phase AC input: 30–275 A/leg · Trickle: 10–50 A
Trims AC output voltage for long cable runs
After any AC power loss, dial resets to 60 A (3‑phase) / 15 A (trickle)
Ramp the 3‑phase dial up incrementally, 30–50 A per step
ThunderBank — Turning Off (Moving Locations or Storage)
Unplug or turn off exporting ThunderBolts first (Or set external switch to Normal Ops/No Export)
3-position switch slowly through Charge (pause ~3 s) to Off
EMERGENCY STOP is not approved as a method to turn the unit off — emergencies only.
Load Shedding — Managing The Fleet When Walking Away
Leave ThunderBank On
Keep ThunderBolts in ThunderBank/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 in ThunderBank/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 = 12V lights + inverter live, loads run, normal operation
OFF = charge-only, not truly off. 12V + inverter down. Battery still accepts solar/shore. Only truly off when unplugged. Loads still run if plugged into a power source.
External switch (by charge plug)
NORMAL OPS / NO EXPORT
Required when plugged directly into grid or a generator
ThunderBolt powers its own loads normally
Won't export to a ThunderBank
External switch (by charge plug)
THUNDERBANK / EXPORT
Default when paired with a ThunderBank
Exports automatically when above Min Battery SOC
Pauses while TBank has another 3‑phase charge source, then resumes
Safe to disconnect while exporting — anti-islanding drops the output. Also handy in No Export: before turning off the TBank, when on grid/genset, or when testing cables.

Troubleshooting (Quick Actions)
Air conditioning struggling, interior compartment 100–119°F. Call Lightnin
for service. Monitor closely and mitigate by reducing loads / charge rate.
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.
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 external switch to Normal Ops/No Export
or unplug.
Air Conditioning, Solar, Alternator
A/C setpoint 80°F or less. Input/output panel sensors run
~+20°F above interior compartment when in use. 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.
