Vszerda 30A 12V 24V Solar Charge Controller LCD USB

SKU CH-AP82-1T1T2

30 A PWM solar charge controller handles 12 V or 24 V systems, supports 32 battery types including lithium, and provides dual USB outputs up to 2.5 A

  • Auto-detects 12V or 24V systems for simple setup
  • Charges 32 battery types including lithium and LiFePO4
  • Three-stage PWM management protects battery health
  • Dual USB ports deliver up to 2.5A for devices
  • Multiple protections guard against short-circuit, overload and reverse current

Solar charge controller for multiple battery types

The Vszerda 30A unit manages charging for 12V and 24V systems and supports 32 battery profiles, including lead-acid, lithium-ion and lithium iron phosphate. It uses three-stage PWM regulation with an industrial microcontroller to control the process. Maximum solar input is 23V for 12V batteries and 46V for 24V batteries.

LCD display and dual USB outputs simplify

A built-in LCD shows real-time data and allows one-key adjustment of floating, discharge and recovery voltages. The controller remembers settings after power loss. Two USB ports supply up to 2.5A combined for phones or small devices. Multiple protections guard against short circuit, open circuit, reverse polarity and overload.

Check panel voltage and battery string count

Ensure your solar array open-circuit voltage stays below 23V for a 12V bank or 46V for a 24V bank. Verify the battery chemistry matches one of the supported profiles — three lithium-ion strings at 11.1V or four LiFePO4 strings at 12.5V. The controller handles up to 30A charge current, so size wiring and fuses accordingly.

Questions about this item

What battery types can I add or replace later with this 32-type compatible controller?

It supports 32 battery types including 12V or 24V lead-acid, 3-string 11.1V lithium-ion and 4-string 12.5V LiFePO4, all auto-detected.

At what solar voltage does the 30 A limit stop accepting more panel power?

The controller accepts up to 23 V on a 12 V battery or 46 V on a 24 V battery; above that the 30 A ceiling is reached and excess power is clipped.

How warm does the dual-MOSFET design get when both USB ports supply 2.5 A continuously?

Dual MOSFETs and PWM charging keep heat low; with 2.5 A USB load the unit runs cool enough for enclosed mounting without active cooling.
