Great product

Rohan Matthews on Aug 4th 2021

I installed the unit over 3 months ago and it has outdone my expectations. It charges my 2 135 Ah batteries faster than my old unit on solar, slower via the alternator. I think I will see even more that 10 years out of these batteries, that's what my previous Renogy system saw me achieve with a constant voltage solinoid rather than DC DC. Highly recommend this unit. Will be adding more solar in the near future and will be buying the panels from Renogy, don't touch ebay panels unless you like getting a 10th of what you paid for. The bluetooth is a great feature as well, just a pitty it's not built in in this day and age, and allows me to see both vehicle and house battery status. I love seeing the vehicle battery charging when the house batteries are full, such a great use of the power.

Review on the 50amp charger,

Harsha Dissanayaka on Oct 19th 2020

Awesome product & looking forward to use these products more regularly with my customers . Only one disappointment was the very delayed postage/delivery which I had to put a customer on hold for quite awhile. Apart from that great product looking forward to dealing with you again. Thanks, Harsha Dissa, Director , Yakka ATS Pty Ltd Australia.

50A DC-DC Charger

Kate Fraser on Mar 4th 2020

I upgraded my vehicle to 400 ah Lithium Batteries, when choosing a DC-DC charger I was very interested in being able to maintain my vehicle start battery during long off-grid trips. The Renogy DCC50S came in at a great price and has all the features I was looking for. I have comprehensively tested my new Lithium charging system and am very impressed with the performance of the DCC50S, the only issue I would advise on is to mount the unit where heat can be dissipated, this unit can get very warm when pushing the full 50 amps through it.
