Xantrex TrueCharge2 24V/20A Smart Battery Charger w/ 3 outputs (804-2420-01)

Sale price$830.00


Building on the success of the TRUECharge™2 12-volt battery chargers, Enerdrive now offers the new Xantrex™ 24-volt battery chargers, designed to meet the specific needs of marine and commercial markets. 

Available in 10A, 20A and 30A versions, each model packs a powerful universal charger (90-240Vac, 47-63 Hz) in an ultra-compact, lightweight package.

TRUECharge2 battery chargers are highly versatile and can be mounted in multiple positions, thanks to their inherent drip-free design characteristics. 

TRUECharge2 delivers outstanding low electrical interference, coupled with efficient, power factor corrected, multistage charging capability. Installation is a breeze, thanks to the easy access AC and DC wiring compartments. The easy-to-read display can be augmented with an optional remote panel.



TRUECharge2 24-volt chargers are available with parallel stacking feature which allows you to double the output current when used with the optional REMOTE PANEL (part #808-8040-01).

Three Stage Charging

Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current delivered to the batteries in three automatic stages:

  • Bulk: Replaces 70-80% of the battery’s state-of-charge at the fastest possible rate.
  • Absorption: Replenishes the remaining 20-30% of charge, bringing the battery to a full charge at a slow, safe rate.
  • Float: Voltage is reduced and held constant in order to prevent damage and maintain batteries at a full charge.

TrueCharge 2 Remote Panel

The TRUECHARGE 2 Remote Panel is designed for use with TRUECHARGE 2 Battery Chargers. This full-function remote allows you to monitor and control battery charger performance from a remote location, including features not accessible from the charger’s onboard display. The TRUECHARGE 2 Remote Panel reads like a fuel gauge and displays critical information on charging of battery banks. It is very easy to install, read and operate, connecting with the battery charger through the included telephone cable.

Remote Features:

  • Gives the user flexibility to set maximum charger output current
  • Allows the charger to be powered on or placed into standby while AC power is connected
  • Programs the charger for battery type and temperature
  • Displays faults and warnings, basic battery level and settings
  • Displays the current status of each battery or each battery bank
  • Simple push buttons to change charger settings
  • FCC Class B compliant

Whats Included:

  • TRUECHARGE 2 remote panel
  • 7.6 m (25′) 6-conductor crossed telephone cable
  • Mounting template and 1 1/2″ NPT locknut for mounting
