20A AC Battery Charger
Key Features:
- Multistage Charging: Fully automatic charger capable of charging 3 separate battery banks.
- Separate Battery Banks: Isolated charging design ensures battery bank one is independent from banks two and three.
- Programmable: Customize battery bank 1 with a different charge algorithm compared to banks 2 and 3.
- Current Control: User-adjustable current output (e.g., reduce the 60A unit to run off a 1kVA generator).
- Smart Charging: Automatically regulates output based on connected loads.
- Wide AC Input Range: Operates on both 110V / 60Hz and 240V / 50Hz.
- LED Display: Intuitive “set and select” menu with scrolling charger status.
- Silent Mode: Disables cooling fan for quiet operation, reducing charge output by half for up to 12 hours.
- Temperature Sensor: Includes a battery temperature sensor with a 7.5-meter cable.
- 5-Year Warranty: Backed by an Australian company renowned for excellent customer support.
Multistage Charging Process
The Enerdrive | Dometic 20A Battery Charger is a fully automatic, “set and forget” charger designed to quickly and accurately recharge batteries while maximizing their service life. Its multistage smart charging technology allows permanent connection to your battery banks.
Four Primary Charge Stages:
Bulk/Boost Charge:
Charges at full rated output until the battery reaches its absorption voltage.
Recovers approximately 80% of battery capacity as quickly as possible.
Absorption Charge:
Maintains steady voltage while replacing the remaining 20% of capacity.
Current gradually decreases as the battery approaches full charge.
Float Charge:
Reduces voltage to a safe, constant level to prevent overcharging.
Supports additional loads like DC lighting and refrigerators.
Allows the charger to function as a DC power supply.
Maintenance Charge:
After 7 days in float mode, the charger switches to bulk mode to agitate the battery electrolyte.
Helps extend battery service life.
Priority Charging
The 20A Battery Charger prioritizes charging Bank 1 (main house battery bank) to recharge it quickly before transitioning to banks 2 and 3.
Flexible Battery Chemistry:
Supports different battery types across banks (e.g., AGM for house and lead calcium for start banks).
Override Function:
Recovers all 3 banks evenly when needed, then resumes prioritizing Bank 1.
Lithium Battery Compatibility
Designed to meet the unique requirements of Lithium batteries, the Enerdrive | Dometic charger delivers a constant current/constant voltage charge algorithm.
Efficient Charging:
Every amp-hour delivered is accepted as one amp-hour into the battery.
Maintains constant current until voltage peak is reached, then switches to power supply mode.
Display Panel
The LED display provides essential information at a glance:
- Charger amps, battery voltage, and charge state alternate continuously.
- In float/power supply mode, load amps are displayed for real-time monitoring.
- Allows programming of all charger settings and activation of silent mode.
Silent Mode
Activate silent mode by pressing the “SEL” button for 5 seconds.
- Fan-Free Operation: Ensures quiet and safe operation, ideal for nighttime use near sleeping areas.
- Limited Output: Reduces current output to 50% for up to 12 hours before returning to normal mode.
Battery Temperature Sensor
Included as standard with all Enerdrive | Dometic Battery Chargers, featuring a 7.5-meter cable for accurate temperature monitoring.
