Certification

1. What type of alternator is this on-board battery charger compatible with?

This battery charger is compatible with both traditional and smart alternators. However, since standard/traditional alternator has a fixed voltage when charging, while smart alternator has a controlled charging output based on operating conditions, it is required to connect the charger to the smart alternator through the Vehicle Ignition Port by the IGN Signal Wire comes with the package.

2. What will happen if the service battery is fully charged?

This Renogy's DC to DC MPPT on-board Battery Charger has a built-in Voltage Sensitive Relay (VSR), thanks to which the charger will Trickle Charge the service battery and maintain its fully charged status, and will also Trickle Charge the starting battery via solar panels. The VSR also ensures reliable isolation between the starting battery and service battery, avoiding charging interference.

3. What types of battery does the charger support?

This controller supports Gel, AGM, Flooded, and Lithium battery, but please make sure to set the correct battery type once it is installed. For battery settings please refer to the Manual Book on page 12&15.

4. How do I set the battery since there is no display screen?

To change the battery type you will need to press the push button that is located on the PV+ and ALT+ side of the DCDC, then continue to press the button and the LED will display different colors with each representing a single type of battery. Please refer to the manual on page 15 for Battery Type LED.

NOTES

1. Do not reverse the polarity since the reverse polarity of the battery connections can cause injury and damage to the device.

2. When connecting the charger and the battery, make sure the battery poles are clean when connecting the terminals, select a sufficient cross-section for the connection cable, tighten the nuts and bolts with proper torque as loose connections may cause overheating.

3. Be careful not to over-torque the terminals on the DCDC as over-torquing may cause irreparable damage (Do not exceed 16 N-m / 3.3 ft-lb).

4. Use the following cable colors:

Red: positive connection

Black: negative connection

5. If the battery charger is connected to the starting battery and solar panels at the same time, the maximum input current will be 15A for each; if the battery charger only connects one of the two DC inputs, the maximum input current will be 30A.

Brilliant with room for improvement - but easy to DIY

Dan on Feb 10th 2023

Love it. But in the UK, PV output isn't great. So added a 60A rated relay to cut off the PV input, controlled by the D+ (engine on) feed on my Sprinter W906, so can charge LiFePO4 batteries at 50A from ALT input (need appropriately sized cable from starter battery) when the engine is running. If Renogy added this already, or adjusted the charging algorithm to accommodate such scenario (low PV power) it would be perfect. Haven't observed any overheating issues, but may add a 12v computer fan to help shift some air across the rear just in case. Also would like an option to dual charge [from PV] both starter battery and leisure battery (eg before leisure battery is full) in case static for some time to keep starter battery topped off, but would need dual charging logic (lead acid vs LiFePO4) so maybe a bit much to ask.

A brilliant charge with some issues and one major heating issue

katey jane andrews on Jan 3rd 2023

Been using the 50 amp charger for almost 2 years to charge 2 AGM batteries, No issues to report for these batteries. Bought a 170 lithium battery from renogy 4 months ago and one major issue shows up every-time. The charger will overheat and go into error 6 mode when driving using the alternator. Why it does this, the lithium battery will take the full 50 amps until it reaches 14.4 volts. I use a solar cut off switch to gain the full power when driving, this is causing an overheating issue and is the same when the solar has turned itself off when dark. The charger is overheating in Scotland in Mid winter and where the charger sits its about 15c and it has plenty of air. Renogy you need to have active cooling like a small inbuilt fan to fix the overheating? I use a small fan to help it stop overheating. The large terminal screw bolts are far too short for large cables and is a struggle to get the cables screwed down, All you need to fix this problem are longer terminal screw bolts. In countries like the U where the sun is low or never out at all, you need to add a solar power cut off switch, this will fool the charger in thinking its nigh so will go from 50% 25 amps per 50 mode to 100% mode. So if you leave the solar on on a cloudy day, yo will get 25 amps from the alternator and maybe 1 amps from the solar, you are then losing around 24 amps. I would like to see the charger use an algorithm when driving, so it measure the solar output which would gain what ever it needs from the alternator. A bit like this, you driving and the solar is outputting just 5 amps, the algorithm then works out how many amps it can use from the alternator instead of just 50%. so would be 45 amps from the alternator and 5 from the solar making up the 50 amps. I give it 5 stars because I have fixed all the faults apart from the short terminal bolts, but TBH I shouldn't have to fix any!

DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT(New Version)

Roy on Nov 29th 2022

This is a great piece of kit that is very easy to wire up. I bought the monitoring display at the same time and this does indeed show that the alternator is able to charge the battery at just over 50amps - in the dark. If the solar is producing any power at all - it splits the charging capability equally between the two sources. This is clearly not a problem when you're parked (not running your engine) or driving at night - no solar. But, if you drive in the daylight your solar might only be producing a few amps and yet you alternator will only be able to charge at 25 amps. The system prioritises solar but in my opinion it would be better if it prioritised the alternator. I solved this problem by installing a switch to isolate the solar when driving and in this way the alternator side produces and charges at 50 amps. I've only got 125 watt solar panel and the best I ever see is about 7 amps. So driving in full sun and an empty battery the best the charger would put in is 32 amps. Isolating the solar solves the problem. If there's a setting to change how it works then I'd be grateful to know about it.

DCC50S

Nick Mead on Jun 27th 2022

Considering which equipment to buy I downloaded instruction manuals from various manufacturers and found Renogy was the most straightforward to understand so I bought from them an ac-dc charger, a lithium battery, the dc-dc DCC50S with a BT2 and a 1000w inverter. I went for a photon universe 200w solar panel since Renogy didn’t have a comparable device available. Everything was connected up and it just works. Their app is easy to use and understand so I am happy with my choice of purchase

No temp adjustment for Lithium

Guido on May 29th 2022

Brilliant charger, easy to connect up so long as you use a ground bus bar, but disappointed by the poor instructions regarding the smart alternator, & that there's no temperature adjustment if you have a lithium battery connected (even a Renogy one).

12v 50A DC - DC MPPT Controller with Bluetooth option

Ron Butler on Apr 9th 2022

Well after having this fitted for just over 2 weeks I can honestly say how easy it was to fit. Solar is to be fitted over the next couple of months again we will be getting a renogy kit, well worth the money our last big item will be 3000w 12v inverter to run all our electrical equipment, We are well pleased with all our purchases.
