Maxon offers a host of industry-leading charging solutions for auxiliary batteries. Some of these solutions help optimize the re-charge of batteries by making the most out of the power that is available (generated by the alternator). Only solar panels add additional power beyond what the alternator generates and only solar panels can charge when the engine is off. The optimal auxiliary battery charging solution depends on a fleets specific needs and re-charge profile (e.g. run times between stops, climate, etc.). Contact your Maxon sales representative to discuss the best solution for your application.
