PWM charge controller 60A 12V 24V 36V 48V with display
PWM 60 A charge controller VS6048AU: 12/24/36/48 V Auto, PV 96 V.
For off-grid systems; verify panels, battery and protection devices.
Need to manage battery charging in an off-grid solar system? The VS6048AU handles up to 60 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.

Add the Voc of series-connected modules and apply the temperature coefficient for the coldest conditions. Voltage, current and power must remain within controller limits.
Frequently asked questions
Is it PWM or MPPT?
The VS6048AU uses PWM; 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.
