It features automatic alternator detection via the D+ signal or voltage sensing. We recommend using 10mm² to 16mm² cabling (depending on length) to minimize voltage drop. A Battery Temperature Sensor (BTS) is included to optimize charging based on real-time conditions. Questions & Answers Is this a genuine original part? This is a premium quality TBB Power part, supplied by Solarika, manufactured to meet or exceed original equipment (OE) standards for vehicle battery management. How do I know if it is compatible? If you have a 12V vehicle system (Euro 5, Euro 6, or older) and need to charge a leisure battery bank at up to 45A, the DM1245 is an ideal fit. Check your required charge current against your battery manufacturer's recommendations. Does this unit include a solar MPPT input? No, the TBB-DM1245 is a dedicated DC-to-DC (alternator-to-battery) charger. For dual solar and alternator charging, please look for the TBB Nemo or DMT series units. Note: Please verify your system voltage and battery chemistry requirements against the specifications above before purchasing.
