Issue
Procedure/Remedy
Vulcan - Blank LCD display,
no AC output power and
power button light not
illuminated.
Vulcan’s battery management system (BMS) has shutdown
Vulcan due to a low battery voltage from discharge. The battery
needs to be recharged.
1. Plug the Vulcan into an AC power source at the AC input
plug located at the back of the unit or,
2. Attach solar panels with a minimum open circuit voltage
of
22Vdc
to the MC4 connector plugs,
Figure 5
.
3. If the system does not recharge, contact
Vulcan - No AC voltage
output displayed and no
voltage at the output
receptacles.
Turn on the power on/off button located at the upper left of the
enclosure. The button will illuminate with a green glow and the
voltage display will activate after 10 seconds. If this does not
solve the issue proceed to the following segment.
The Vulcan system is experiencing one of the following
conditions:
●
Inverter Low Battery Cutoff condition. In order to
preserve battery capacity, the AC output power will shut
off when the battery voltage discharges down to
11.2Vdc
.
Recharge the system to clear the condition.
●
Inverter overload condition. Vulcan has a built-in
automatic restart on an output overload. However, If the
inverter is shutdown and does not restart, remove the
load and cycle the power on/off button. The output
power will be restored.
●
Power save mode. The AC output will shutdown after 25
hours of no-load/idle. The power on/off button must be
cycled to restart.
System not charging from
solar panels.
●
Check the connections and cabling between the solar
panels and the Vulcan/Smart Store MC4 connectors.
●
Ensure the Vulcan is not fully charged. If the battery is
fully charged then the charge controllers will not harvest
energy from the solar panels. A load must be added in
order to activate charge controller energy harvesting.
●
Ensure the solar panels have a minimum open circuit
