Explaining the RedVision Load Disconnect feature

What does the RedVision load disconnect feature do

 

The RedVision Load Disconnect feature allows you to automatically switch off the 10 RedVision channels, and a REDARC RS series inverter if connected to RedVision. This feature is intended to be used as Load Disconnect for non-essential loads and can be programmed to switch off the channels and Inverter based on your auxiliary battery State of Charge, or Voltage (The State of Charge is only available if you are using RedVision in conjunction with the REDARC Battery Management System).

 

The RedVision Load Disconnect requires programming through the REDARC Configurator App, which gives you the option to select either the battery State of Charge, or battery voltage to trigger the disconnection. Also, in this set-up you will be required to set the reconnect trigger, which determines how much the battery must be recharged before the channels can operate again.

 

Please note:

 

If a channel has been selected as Master Switched within the Distribution Box Channel configuration, this is considered a non-essential load and will be switched off when the Load Disconnect is active. Any channel that is NOT Master Switched will remain active and continue to draw power from your battery. For this reason, it is recommended that the load disconnect is set higher than the minimum battery State of Charge or Voltage that you wish to eventually discharge to – leaving your essential loads to run a little longer until this point. It is within this period between Load Disconnect and minimum State of Charge/Voltage that a charge input should be sourced to prevent over-discharge of your auxiliary battery.

 

For the purpose of the below examples, we will assume that the fridge is set to “not master switched” as per the below image, and that all other channels are set to “master switched”.

Example:

 

The recommended depth of discharge for most AGM Batteries is 50%. To avoid potentially reaching this level of discharge it is recommended that you set your Load Disconnect to 60% or higher. Setting the Load Disconnect at this level will still allow the essential loads such as your fridge to run for a period before your battery drops to the minimum recommended state of charge. Within this time period, a charge input should be sourced to prevent over-discharge of your auxiliary battery. The reconnect setting should be at 65% or higher to allow the battery time to recharge before loads are active again

>60% = Everything running
<60% = Only the Fridge Running
<50% = Battery Flat (nothing running)
return to >65% = Everything running again

 

 

A LiFePO4 (Lithium) battery typically has 80% usable power, and will self-protect at this level. For this reason, it is recommended to set your Load Disconnect to 30% or higher. Setting your Load Disconnect above the battery self-protection level will allow the battery to remain “powered”, continuing to run your essential loads. Keeping the battery above the self-protection level allows the REDARC Battery Management System to retain your battery settings and State of Charge calculations. The reconnect setting should be at 40% or higher to allow the battery time to recharge before loads are active again.
