Battery Bank Preparation
The Conext XW+ 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.
Choose Flooded, AGM, Gel, Lithium-Ion, or custom batteries for your installation.
Consider the following recommendations for battery use:
• Use only deep cycle types for inverter applications.
• Use the same battery type for all batteries in the bank.
• Use only batteries from the same lot and date in your battery bank.
This information is usually printed on a label located on the battery.
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.
• Always use and connect the Battery Temperature Sensor (BTS).
• Always verify that the configured battery type matches the battery type
being used.
• Custom battery settings should be configured by qualified personnel only.
• When using Lithium-Ion batteries, ensure that the battery pack being used
includes a Battery Management System (BMS) with safety controls.
• Do not use wet type Lithium-Ion batteries.
Failure to follow these instructions can result in death or serious injury.
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+ 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 damage to equipment.
