Důležité úvahy:
- Ensure appropriate fuses/breakers are installed on all positive lines as indicated in the diagram.
- The ACC ignition wire is recommended for vehicles with smart alternators to ensure proper charging initiation.
- Maintain proper cable gauge for the current draw to prevent voltage pokles a přehřátí.
6. Návod k obsluze
6.1. Výběr typu baterie
Stiskněte tlačítko "SELECT" button on the charger to cycle through and choose the appropriate battery type for your auxiliary battery (AGM, Gel, Calcium, Lead Acid, or LiFePO4). The selected battery type will be indicated by an illuminated LED.
6.2. Reverse Charging Function
To activate reverse charging and revive a flat start battery from your auxiliary battery, press the "REVERSE CHARGE" button. This feature ensures your starter battery remains charged for off-road use.

6.3. DC Charging Priority
The charger is configured with DC charging priority. When both the vehicle's start battery (DC input) and solar panels are connected and meet the startup conditions, the charger will prioritize the vehicle battery input. If solar charging is already active, the system will continuously monitor the DC input and automatically switch to DC power if conditions are met.
- Startup Conditions:
- DC vstup: 13-24V
- Solar Input: 13-26V

- Check the condition of fuses/breakers regularly and replace if necessary with the correct rating.
8. Řešení problémů
Pokud narazíte na problémy s nabíječkou, postupujte podle následujících běžných kroků pro řešení problémů:
- Charger Not Activating:
- Verify that both DC input (from start battery) and/or solar input meet the minimum voltage requirements (DC: 13-24V, Solar: 13-26V).
- Zkontrolujte všechna připojení, zda jsou správná usazení a polarita.
- Inspect fuses/breakers for continuity.
- Ensure the ACC ignition wire (if used) is receiving power when the vehicle is running.
- Nízký nabíjecí výkon:
- Confirm the correct battery type is selected on the charger.
- Zkontrolujte nadměrný objemtage drop in wiring due to undersized cables or long runs.
- Ensure solar panels are clean and receiving adequate sunlight if solar charging is active.
- Verify the alternator is functioning correctly and providing sufficient voltage.
- Přehřívání:
- Ensure the charger is installed in a location with sufficient airflow.
- Remove any obstructions around the cooling fins.
