About this item

  • 【DC to DC Charger Function】Flexibly provide two charging methods for service batteries. One is by connecting the starter battery of a car's alternator, and the other is by connecting solar panels to charge home batteries. Provide proper charging for AGM/GEL, Lead acid, Lithium and Calcium batteries.
  • 【Smart MPPT Charging】With built-in Maximum Power Point Tracking (MPPT), the DC-DC car charger will achieve high charging efficiency from solar panels at a suitable voltage. The MPPT solar energy intelligent control management system has a charging memory function that can record according to the user's charging habits.
  • 【One-Way Charging】The addition of primary and secondary battery isolation achieves greater safety performance. In order to prevent the loss of power from the life battery, we have added one-way charging to prevent the life battery from back-charging and power consumption.
  • 【Complete Protection Measures】It has multiple protection functions, including engine start battery low voltage protection, input and output reverse polarity protection, solar input overload protection, overcharge protection, short circuit protection, and over temperature protection.
  • 【Easy To Use】There are wirings for solar panel, alternator and battery. Normal charging wiring will be indicated by light to better determine whether the connection is abnormal.

    I bought the 40 amp DC to DC charger a few weeks before my battery arrived. The charger arrived quickly and the product looked good quality. Once the battery arrived the return date had already passed for the DC to DC charger. I installed everything as per the instructions, but unfortunately there was an issues with the charger. I emailed Eco-Worthy with the issue and they were very responsive. They walked me through several troubleshooting steps, but in the end there was something wrong with the unit. Eco-Worthy apologized for the inconvenience and are sending me a replacement unit. I requested them to downsize the unit to a 20 amp, which they agreed to and will also be refunding me the price difference of the two units. I'm very pleased with my interaction with Eco-Worthy. The customer service was second to none. Highly recommend dealing with them.

    Is not sealed and there is moisture in the window where you are supposed to get your reading. This is mounted on a wall beside an inverter. Inverter is fine so product is not sealed.

    so far the unit is doing what I needed to perfectly. I had confusion from the book on setting it for lithium batteries but turned out that switching it is easy and you don't have to do the hold for button for 5 seconds to set it unless your lithium is has no charge in it. After finding that switching the selector to Lion was all that was needed. I installed this in my semi to have a seperate system for my inverter and my starter batteries. Only a couple days but with a 200ah lithium everything works so well. At first I thought it was weird having all those wires just sticking out but in the end it was brillant as you can make a very neat and tidy install with a few mounted fuse blocks and bush bars.

    I won't install this device for a couple of months. I do have Eco Worthy gear on my boat and it performs perfectly. That in mind, I don't hesitate to purchase their gear because it's actually well made, safe and durable.
    I have no doubt this DC to DC charger will perform flawlessly once installed between my 280 ah Eco Worthy LiPO4 battery and 200 ah lead acid starter batteries.

    They advertise a 40 amp DC to DC charger and controller when really it's a 20 amp DC to DC charger for my vehicle and 40 amp from the solar. I thought it would be 40 amp from the DC to DC and also from this sort that would make sense but if you start reading their tech support sheets it does not support for the amps from the DC to DC

    Fonctionne très bien! Support à la clientèle moyen! Il m’a été difficile de comprendre si la gestion du solaire et du chargement à partir de l’alternateur et des conséquences (risques) sur l’alternateur serait bien pris en compte. Les instructions sont simplistes et les réponses du support aussi. En plus l’ajout d’un moniteur a été nécessaire pour bien gérer le courant et la charge. Donc oui il gère les deux mais un contrôleur solaire et un Mppt Dc to Dc ferait aussi très bien l’affaire!
