  • Page 7: Unpacking

    STERLING POWER UNPACKING WHATS IN THE BOX Understanding the Product Before we proceed with the install it may be helpful to understand what the Vulcan is, what it can do, and what a very simplified system will look like. What is a Vulcan? The Vulcan range offer a selection of high powered inverter/chargers with photovoltaic (herein called PV) input capability built in.

  • Page 11 STERLING POWER INSTALL FIRST INSTALL - AC AC install precautions We don’t want to be boring - but it is very important that we re-iterate here, very clearly, that carrying out an AC install can be dangerous if you do not ‘respect’ it. Please read and understand the following forewarnings before going through with an AC install.

  • Page 12: First Install : Ac

    STERLING POWER INSTALL FIRST INSTALL - PV / SOLAR Solar/PV Precautions This solar circuit is non-isolated. Do not share multiple Vulcans to the same solar array. Please ensure the inverter and PV circuit is fused and has an installed circuit-breaker so the system can be isolated if needed.

    STERLING POWER INSTALL SCREEN AND SETUP Post install celebration We’re there. You’ve done it, the Vulcan is now installed (hopefully) without any damage. Cables are secure, contacts are tight, all is well in the world. Now let’s get to understanding and actually using the Vt485500 Power ON/OFF Once the install is complete, you’ll find the ON/OFF toggle switch on the right hand side of the Vt485500.

  • Page 15 STERLING POWER INSTALL SETTINGS LIST AND PARAMETERS LCD settings To access the settings, integral to the control and configuration of the Vulcan, press and hold the ENTER button for 5 seconds. You will be able to move UP or DOWN through the setting parameters list by using the UP or DOWN buttons.
  • Page 16 STERLING POWER INSTALL SETTINGS LIST AND PARAMETERS OVER-TEMP RESTART : 07 Similar to (06), this dictates how the Vulcan recovers from an ‘Over-Temperature’ event. AUTO RESTART DISABLED (Default) - Vulcan must be manually recovered from an over-temp state. AUTO RESTART ENABLED - Vulcan will self-recover. If the fault is not resolved it may repeat. AC OUTPUT FREQUENCY : 09 Configure the AC output frequency - according to what your appliances require 50Hz is the default.
  • Page 17 STERLING POWER INSTALL SETTINGS LIST AND PARAMETERS Decides the behaviour of the Vulcan screen’s backlight. BACKLIGHT CONTROL : 20 Light ON (default) Light OFF AC ABSENCE ALARM : 22 Decides if the Vulcan should alarm/beep if the AC IN line is interrupted ALARM ON : Vulcan will alarm if the AC in-line suddenly disappears (default) ALARM OFF : Vulcan will not alarm This setting dictates whether the Vulcan returns to AC priority in the event that a battery overload occurs.
  • Page 18 STERLING POWER INSTALL SETTINGS LIST AND PARAMETERS If this voltage threshold is exceeded, one of two events will follow. If battery power is the only source available the LOW DC VOLTAGE : 29 inverter will shut down. If PV is available the Vulcan will focus on charging the batteries rather than providing AC to your domestic circuit.

  • Page 19: Parallel/Three-Phase

    STERLING POWER PARALLEL/THREE PHASE COMBINING MULTIPLE VULCANS VT Parallel and Three-Phase The VT-485500 has the somewhat unique feature of ebing able to combine their capabilities to meet and overcome otherwise impossible to meet conditions. By utilising the communication lines on the VT you can combine their output power in either parallel single phase or three phase configurations.
  • Page 20 STERLING POWER PARALLEL/THREE PHASE COMBINING MULTIPLE VULCANS Parallel process and instructions The cabling for the VT-485500s, in a demonstration set of three (so the remaining configurations can be inferred) Notes: is as follows. All inverters must be set-up with identical output parameters before being ran and configured in parallel. IE, in sequence, turn an inverter on, set up the parameters to what you need them to be, turn them off.
  • Page 21 STERLING POWER PARALLEL/THREE PHASE COMBINING MULTIPLE VULCANS Three phase configuration As before - Solar arrays cannot go to any more than a single Vulcan in the set. All Vulcans must share the same notes battery bank. All parameters must be shared. Do not connect the current sharing cable. When setting the system up in three-phase, set each inverter up independently, one at a time.
  • Page 22 STERLING POWER PARALLEL/THREE PHASE COMBINING MULTIPLE VULCANS Three phase configuration For systems larger than 3- you expand the array repeatedly. notes I print, below, a system incorporating the maximum (nine) number of Vts running in three phase, so it may help you understand the modularity a bit further.
