Battery Bank Preparation
WARNING
BATTERY TYPE AND SET UP HAZARDS
Incorrect battery configurations or settings for battery types can lead to dangerously high
battery temperature, fire and explosion.
To avoid damaging your batteries during charging or equalization, and to minimize the risk
of fire or explosion consult battery manufacture's documentation before setting battery
parameters and follow the battery manufacturer's recommended settings.
n Always use and connect the Battery Temperature Sensor (BTS), except when an
external Battery Management System (BMS) that can fulfill this function is present.
n Always verify that the configured battery type matches the battery type being used.
n Custom battery settings should be configured by qualified personnel only.
n When using Lithium-Ion batteries, ensure that the battery pack being used includes a
Battery Management System (BMS) with safety controls.
n Do not use wet type Lithium-Ion batteries.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
The Conext XW Pro Inverter/Charger operates with batteries as its source of DC power.
If DC power sources are connected directly to the inverter, the DC rating of the inverter
can be exceeded and the inverter can be damaged.
NOTICE
OTHER SOURCES OF DC POWER
Do not connect DC power sources, such as PV arrays, wind turbines, or micro-hydro
turbines, directly to the Conext XW Pro Inverter/Charger. Connect DC power sources to a
charge controller and then to the battery. DC surge protection should also be installed.
Failure to follow these instructions can result in equipment damage.
Choose Flooded, AGM, Gel, Lithium-Ion, or custom batteries for your installation.
Consider the following recommendations for battery use:
n Use only deep cycle types for inverter applications.
n Use the same battery type for all batteries in the bank.
n Use only batteries from the same lot and date in your battery bank. Thisinformation is
usually printed on a label located on the battery.
