much since it is a momentary readout and must be used as a guide only. We always encourage the use of the state-of-charge readout for accurate battery monitoring.

Besides the main function of the Xantrex Battery Monitor— displaying the actual battery status—this monitor offers other features. The readout of actual battery voltage, current and temperature (with optional temperature sensor), the ability to store history data, the PC computerlink and the Super-lock function are just a few features of the Xantrex Battery Monitor. These features are more specifically explained in the corresponding sections of this manual.

2 Setting up the Xantrex Battery Monitor

Before proceeding with this chapter, please make sure your Xantrex Battery Monitor is completely installed according to the enclosed installation guide.

When your Xantrex Battery Monitor is installed it is time to adjust the battery monitor to your battery system. But before discussing the functions in the setup menu, four important items are explained in the next sections. These four items will help you become more familiar with battery monitoring. The actual setup menu functions are explained in “Function overview” on page 4.

Charge Efficiency Factor (CEF)

Not all energy transferred into the battery during battery charging is also available during discharging of the battery. The charge efficiency of a brand new battery is approximately 90%, meaning that 10 Ah must be transferred to the battery to get 9 Ah actually stored in the battery. This efficiency figure is called Charge Efficiency Factor (CEF) and will decrease with battery age.

The Xantrex Battery Monitor automatically calculates the CEF of the battery as the battery is discharged. The level at which the CEF is recalculated is variable and is linked to the discharge floor set in F05. The CEF algorithm starts operating when 10% of the difference between 100% and the discharge floor is discharged from a fully charged battery.
