## Description

Renogy's MPPT charge controller with alternator power input is designed with multi-stage, multi-input charging. It can charge a service battery from a starting battery linked to an alternator or by utilizing solar panels connected directly to the unit. While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first! With multi-stage charging and multi-chemistry functionality, Renogy's 50 Amp MPPT charger has you covered whether you're using Flooded, Gel, AGM, or Lithium batteries. Innovative MPPT technology with high tracking efficiency up to 99% and peak conversion efficiency of 97%.

Review: Works well - Works as advertised. Takes input from the solar panels or the 12VDC aux from the 7pin trailer connector. We can now charge the trailer battery when on the road.
Review: Best deal if you don’t have a lot of solar!! - Recharges batteries while driving fast and handles my 120watts of solar NP. Way cheaper than buying them separately unless you have more than 400watts of solar. I’ve used it for 2 years now and have had no problems. Being able to monitor on phone is super handy. I would highly recommend this DC charger if you plan on using solar as well but it’s still a good deal for a 50amp dc-dc smart charger. Love it!
