What it does (in plain English)

• Charges your house battery fast (up to 75A) using any available combination of AC, DC and solar.
• Prioritises solar when it can, to reduce load on the alternator.
• Shows your battery state of charge, charging stage, current flow and more on the RedVision display.
• Includes smart features like Start Battery Charge (top-up) and Start Battery Recovery (jump-start assist), when enabled and configured.

Quick Highlights

• Charging sources: Solar + Vehicle (DC) + 240V (AC).
• System modes: Touring Mode (everyday use) and Storage Mode (parked up for weeks).
• Monitoring: RedVision display + Bluetooth phone apps.

Before you start

• Settings matter. If the battery type/size settings don’t match your actual battery, state-of-charge and charging behaviour can be wrong.
• Install & wiring: Battery management systems should be installed/configured by a qualified auto electrician.

Understanding the RedVision display (the basics)

• Left/Right arrows: move between screens.
• Up/Down arrows: scroll through items/options.
• Soft keys: the buttons beside the screen that change depending on what’s displayed.
• Power button:
  • Press once: opens the power/menu dialogue (includes Touring/Storage switching).
  • Press twice: activates a “Master Switch” (only if a TVMS/load-control system is installed and configured).
  • Hold: puts the display into standby.

Touring Mode vs Storage Mode (which one should you use?)

Touring Mode (normal use / travelling)

• Use this when you’re actively using the van or travelling.
• Runs a 3-stage charge profile (Boost → Absorption → Float) and continues supplying power (unless a fault is detected).

Storage Mode (parked up for weeks)

• Use this for medium/long-term storage when you’re not really using the van.
• Maintains the battery with float/maintenance behaviour and may go into a low-draw sleep mode if there’s no charging source.
• Tip: Storage Mode is best when the van can still receive solar or mains power, or when loads are disconnected and you check it periodically.

How to switch modes

1. Press the Power button once.
2. Select Touring or Storage on the screen.

How to check charging + battery status

1. From the home screen, use the Left/Right arrows to find the BMS / Battery information screen.
2. Look for:
   • State of Charge (SoC %)
   • Charge stage (e.g., Boost/Absorption/Float)
   • Current flow (what’s charging in and what loads are drawing out)
   • Solar input (when available)
3. If you have performance/log options on-screen, you can use the soft keys to view trends (day/hour) depending on configuration.

Battery setup (important after a battery upgrade or replacement)

If your battery has been replaced (especially moving to lithium), the Manager Alpha should be configured to match your battery manufacturer specs.

On the display (Battery Settings screen)

• Chemistry: set the battery type/chemistry.
• Capacity (Ah): set battery size.
• Max Current (A): set the maximum charging current.
• SoC Alarm (%) and Voltage Alarm (V) as desired.

Via RedVision configuration (common installer settings)

• DC Input Trigger: determines when the system starts/stops charging from the vehicle side.
• DC Input Current Limit: can reduce alternator load (often set by an installer based on alternator capacity and cabling).
• Start Battery Charge Mode: can be enabled/disabled.
• Fan Night Mode: can reduce fan noise at set times (may reduce charge output if the unit heats up).

Start Battery Charge & Start Battery Recovery (if enabled)

These features can be incredibly handy — but they depend on correct configuration (and are generally for 12V start battery systems).

Start Battery Charge Mode (automatic top-up)

• When the house battery is full, this mode can automatically charge the vehicle start battery using solar and AC sources.
• It can deliver up to 25A (depending on current limit settings) and targets around 12.8V.

Start Battery Recovery Mode (manual “jump start assist”)

• Manually initiated feature to help recover a flat start battery using the auxiliary battery.
• Runs a recovery cycle (commonly 15 minutes). After completion, you should be able to start the vehicle.

Important: These modes may only be available when the DC Input Trigger is set appropriately (commonly Auto or 12V) and the system is configured for a 12V start battery.

Connecting your phone (Bluetooth)

1. Install the RedVision app (for monitoring/control) and/or the Configurator app (for configuration).
2. On the display, go to Display Settings → Bluetooth Pairing.
3. Open the app, select your display from the device list, and enter the pairing code shown on the RedVision display.

If pairing is painful

• Make sure Bluetooth and location services are enabled on your phone.
• Clear/unpair old RedVision connections on both the phone and the display, then re-pair.
• Avoid having multiple phones connected at the same time.

Quick troubleshooting tips

• Battery % looks wrong: confirm the Battery Settings (chemistry + capacity) match your real battery setup.
• No/low charging from the car: DC Input Trigger and Current Limit settings may need checking by an installer (especially on smart alternators).
• Stored for ages: use Storage Mode and ensure you have a charging source (solar or mains), or disconnect loads and check periodically.
