The EPEVER XTRA series is advanced maximum power point tracking (MPPT) charge controller for off-grid photovoltaic systems, with optional display units (XDB1/XDS1/XDS2). It is designed according to the international standard with higher quality, reliability, and safety. The limitation function of the charging power, charging current, and automatic power reduction function fully ensure stability when working with oversize PV modules(max.1.5 times of rated power) and operating under a high-temperature environment.

Can the lithium battery type be chosen via the LCD and button on the controller?
Yes, the XTRA series charge controller (softwareSV200 or above version ) supports choosing lithium battery type via LCD. But WiFi/Bluetooth module or PC is required if the user wants to customize the voltage setpoints.

Can multiple units be connected in parallel to charge the same battery bank?
Not recommended. the battery voltage that every controller detected has a minor difference. When the battery is nearly full, it is possible that some controllers are charging, and others not, or some are charging with a big current and others are charging with a small current.
