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 socket 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.
