MPPT Charge Controller 30A 12/24/36/48V with EPEVER Display
MPPT 30 A charge controller XTRA3415N-XDS2: 12/24/36/48 V Auto, PV 150 V min.; 138 V a 25 °C.
For off-grid systems; verify panels, battery and protection devices.
Need to manage battery charging in an off-grid solar system? The XTRA3415N-XDS2 handles up to 30 A on 12/24/36/48 V Auto systems, with PV limits that must be checked before wiring.
Check module open-circuit voltage, current, power and battery profile. Cables, fuses and isolation must be sized by a competent installer.
Why is a solar charge controller needed?
The controller manages energy between modules and battery and keeps charging within configured parameters. PWM requires modules matched to battery voltage; MPPT tracks maximum power within its range.

Frequently asked questions
Is it PWM or MPPT?
The XTRA3415N-XDS2 uses MPPT; the two technologies require different panel-to-battery matching criteria.
Can any solar panel be connected?
No. Voc, current, power and series/parallel configuration must follow the manual, including cold-weather voltage rise.
Is it suitable for lithium batteries?
Compatibility depends on available profiles and BMS requirements. Always check both controller and battery manuals.
Is a temperature sensor required?
For lead-acid batteries, temperature compensation adjusts charging voltages; check whether the sensor is included or optional.
What is the connection sequence?
Normally connect battery first, then PV array and finally loads, following polarity, fuse, cable and manufacturer instructions.
