Renogy 12V 30A DC-DC On-board Battery Charger with MPPT for Gel, AGM, and Lithium Batteries Using Multi-Stage Charging, in RVs, Cars, Boats, Yachts, Recommended to Match with 40A ANL Fuse

Very useful and well built item which combines all the features of several components (that other manufacturers would sell separately) all in one compact unit.

Gone the full Renogy set up and this dc to dc charger and mppt is absolutely quality. For the money it’s hands down cheaper than buying them seperate and with the Bluetooth connection you have everything you need.

Simple and easy to install, straight forward instructions included.

Easy to install and well worth having in the winter konths when solar panels struggle

Purchased this item after changing my solar van system & replacing battery with lithium. Unable to get system to register Solar charge. After completely replacing all wires, terminals, connectors, fuses etc & getting multimeter readings to point of contact with controller, it seemed the controller was at fault as all other issues for troubleshooting where address & replaced. Renogy replaced item after 3months of me trying to get to the bottom of the issue. However, replacement had exactly same issue. I have spent MONTHS trying to sort all this out & now find they will not refund as from a third party seller. I am so annoyed as this is a very expensive purchase to just waste so much time & money on & not get it fixed. Just rubbish!

Excellent product

No mention of the solar voltage limit in the listing. My panel p creating 33v puts the unit into fault and causes it to be useless. I bought it ages ago so unable to return. Do not buy unless you are certain your panels will not provide over 30v. (Very low)

Update on 20 September So renagy finally replaced the faulty unit , new one arrived and I set it up couple of weeks ago and system now up and running again. So I would say that the same length of warranty should be granted on Amazon as of the website, on the web site it says 3 years but on Amazon it says 2 years. And customer service is disgusting in the way they made it out to be that I was at fault and not the unit , I sent them every thing and they still came back to say it was my fault , I went through Facebook, Instagram,Google by leaving my negative reviews before any one givin me any help . Have now given 3 stars only cos it taken someone from there Facebook book time to get them to replace the faulty unit. . Cheep and not good quality, unit stopped working for no reason it's a over price paper weight no longer charges system This is a disgrace of a company there unit failed and the company will not help , I sent videos and images as they requested and given me stress as that came back saying I wired the unit up wrongly witch I clearly have not , worse customer service.

Very happy with these batteries.
