If the motorhome is parked outside and has a solar panel fitted, it is recommended to keep the leisure battery connected, to have the power supply unit (PSU) turned on, and turn off the control panel over the door. The solar panel should provide enough energy to keep the leisure and vehicle batteries charged, and the tracking/communication unit will monitor the batteries and let you know if they need charging (if you have enabled email and SMS alert or have a tracking to determine if it needs charging).
If the motorhome is parked undercover in a building or carport or has a storage cover fitted that blocks the solar panel or the vehicle doesn't have a solar panel installed, then it is recommended to turn the PSU off and leave the leisure battery fitted and connected. The leisure battery is required to power the tracking unit over an extended period. The tracking/communication unit will monitor the leisure battery and let you know if they need charging (if you have enabled email and SMS alerts or have a tracking subscription).
