dc to dc charger

Bernard Dubuc on Sep 26th 2021

I am very happy with my purchase I built my van in the south west where it never rains, this summer i drove to Quebec Canada and it rained for 5 days straight, my batteries ran empty so I purchased this unit and it saved the situation, highly recommended.

Love It!

I own a Prius and camp/road trip a lot. I run a lot of devices like a portable fridge and needed something to keep my fridge running while I camp but able to charge my battery at the same time. This device recharges my batter in 2 hours while I drive but the coolest part is I am able to solar charge my battery thought this. The ability to have 2 devices in one (DCtoDC Charger and MPPT) took up less room in my car. That means I can camp for days and my fridge will run the whole time.

Order online and with quick delivery. This will replace my existing MPPT charger to control overall charge profile from all sources. Great price for RV application.

DCC50S. B2B chargeur

Benoit on Aug 5th 2020

Je viens juste de compléter l’installation et je suis impressionné par le bon fonctionnement du chargeur. Fournit un peu plus de 50amp. au début et abaisse progressivement la puissance en fonction de l’état de la batterie. Ma batterie sera dorénavant complètement chargée et maintenue par mon panneau solaire lors qu’à l’arrêt. Grosse déception cependant, ce chargeur est conçu pour aussi gérer le panneau solaire d’une façon vraiment intéressante mais comme la tension de mon panneau excède 25 volts je ne peux l’utiliser (Max solar input voltage : 25V), une spécification que je n’avais pas considéré :(. Je devrai songer à remplacer mon panneau.
