Does the Xantrex EchoCharge work with solar chargers?

Yes, it pairs perfectly with solar charge controllers. Once your house batteries reach the trigger voltage, it directs excess solar amps to the aux bank without interrupting the primary charge.

Can it handle lithium batteries?

It works with various types including AGM, flooded, and lithium, as long as both banks are the same voltage and chemistry. Monitor profiles match standard absorption/float stages.

What if my house bank is 12V and aux is 24V?

Both banks must match in DC voltage (12V or 24V). It's designed for identical systems to ensure safe, balanced charging.

Does it charge from an alternator?

Absolutely—connect it post-alternator or through your battery combiner. It activates when house voltage hits threshold, using alternator surplus wisely.

Is the EchoCharge waterproof for marine use?

It's rugged for boat environments but not fully submersible. Mount in a dry compartment and seal connections for splash protection.

How does it prevent overcharging the aux battery?

Smart voltage limiting caps output at 14.4V (12V) or 28.8V (24V), and it auto-disconnects below trigger levels, mimicking a dedicated float charger.

What's the difference from a traditional battery isolator?

No diode voltage drop (0.7V loss), fully automatic digital control, and it only uses excess current—preserving full power for house loads first.

Imagine heading out on a weekend adventure in your RV or boat, only to find your starting battery dead because the house batteries drained it overnight. That's a common frustration for off-grid enthusiasts, but the Xantrex EchoCharge changes the game. This clever device acts like a smart middleman, channeling excess power from your primary house battery charger straight to your auxiliary or starter battery—without the usual voltage losses that plague traditional setups.

Unlike bulky diode isolators that rob precious volts from your charge cycle, the EchoCharge uses advanced digital sensing to kick in precisely when your house bank hits 13V (12V mode) or 26V (24V mode). It then delivers up to 15 amps of clean, efficient charging to keep everything topped off, automatically switching off to prevent overcharge or interference with your main bank.

Why Choose the EchoCharge for Your Dual Battery Setup?

RVers, boaters, and solar power users swear by this unit for its seamless integration. It taps into spare current from your inverter/charger, alternator, or shore power source, ensuring your engine-starting battery stays ready while your house batteries power lights, fridges, and gadgets. No more babying your batteries or worrying about cross-drainage—it's all handled automatically.

Zero Voltage Drop: Digital design bypasses the inefficiencies of diode-based systems, delivering full-strength charge to aux batteries.
Universal Fit: Handles both 12V and 24V systems effortlessly (as long as both banks match).
Safety First: Over-current, thermal shutdown, and reverse polarity protection keep things reliable in harsh marine or RV environments.
Plug-and-Play Simplicity: Just three wires to connect—positive from charger, positive to aux battery, and a ground. Install it in minutes, no electrician needed.

Perfect for RVs, Boats, and Off-Grid Living

In an RV, pair it with your converter/charger to keep the chassis battery happy during long boondocking trips. On the water, it ensures your thruster or generator starter battery mirrors your house bank's charge from solar panels or the alternator. Off-grid solar warriors love how it maximizes every amp from limited panels, preventing starter battery neglect.

Users report extending battery life noticeably because it maintains optimal float levels without constant cycling. Think of it as your battery system's quiet guardian, working invisibly until needed.

Quick Installation Guide for DIY Success

Disconnect all battery negatives for safety.
Connect the red wire from your primary charger's output to the EchoCharge input.
Run the output wire to your aux/starter battery positive.
Ground the black wire to a solid chassis point.
Double-check polarity, reconnect batteries, and test—charge should flow above trigger voltage.

Pro tip: Mount it away from heat sources and use appropriately sized wire (10-12 AWG recommended for 15A runs) to minimize resistance.

Frequently Asked Questions

Convenient Dual Battery Bank Charging

Xantrex digital echocharge (part#82-0123-01) is designed to charge auxiliary or starting batteries from an inverter/charger or other charging source with limited voltage drop. The Xantrex echocharge detects when the house battery bank is being charged and directs a portion of the charge current to auxiliary or starting batteries. The maximum charger current offered by echocharge is limited to 15 amps.

Product Features

15 A maximum charge current
Automatically adjusts for 12 or 24 volt battery banks (both battery banks must be the same DC voltage and battery type)
Automatically switches on/off without affecting the in-house battery bank or over-charging
Utilizes excess current from the primary charging source
Built-in thermal and over-current circuits
Reverse polarity protection
Easy three wire installation
