This is a automatic AC-DC and DC-DC charger that can charge the main battery through the and starter battery, or Solar panels charge the main battery (some models), DC-DC battery charger designed specifically for motorhomes, campers, ships, etc.
AC Charge
AC charging has priority. When the charger is connected to external AC socket, the AC charging mode will start immediately, stop solar charging or B2B charging. When the AC socket is removed, it will automatically switch to solar charging.
B2B (Battery to Battery)Charge
It means to charge the board battery through alternator and starter battery.
The "D+" signal of the alternator activates the charging converter automatically and switches it off in case of an engine stop.
You can also use DIP switch 2 to achieve automatic charging without D+
1. When the vehicle is running, the vehicle alternator can quickly charge the main battery through the charger at full power
2. The charger can charge the main battery according to the specified voltage and current by boosting or stepping down to ensure that the main battery is in accordance with the standard charging curve charging

MPPT Solar charge controller
Remove the AC connection, stop the engine (D+ low), orientate the solar panels towards the sun. The charger works, the LED "Solar" is lighting.
Controllers according to the MPP technology are continuously and automatically calculating the maximum power yield (MPP) of the solar modules several times per second. The voltage surplus of the solar module will be transformed to a higher charging current for the battery (realised by high-frequency switching controller technology with high efficiency). This surplus of charging current ensures short charging times and the best possible power yield of the solar system.

Other functions
1. Fully automatic charging: In order to continuously charge the battery, the controller can always be connected to the car battery. When the charging energy is stopped, such as the car stops driving, the battery will not discharge in the reverse direction.
2. Multiple protection functions: with overheating, overvoltage, short circuit, wrong connection protection
3.External temperature sensor: The ambient temperature will affect the parameters for charging the battery. The controller needs to perform parameter compensation according to the temperature of the battery, especially in places with large temperature changes. It is strongly recommended to install a temperature sensor.
Note: Lithium batteries do not require temperature compensation
4. Lithium battery automatic wake-up function: When the lithium battery BMS is protected for some reason, the controller can automatically wake up the BMS and continue to charge the lithium battery

!Battery life and efficiency
1 Ensure that the battery installation environment is ventilated and dissipated. The LiFePO4 battery is recommended to work in an environment above 0 degrees Celsius, otherwise the battery characteristics will drop a lot
2. The battery must be fully charged and stored, and it must be charged regularly to ensure that it is not stored under power, otherwise it will affect the battery life
3. Lead-acid batteries that are completely empty must be charged as soon as possible, otherwise it may cause permanent damage!
4. The lithium battery must have a BMS (Battery Management System). Try to avoid completely emptying the battery.
