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. Featured with Remote Temperature Sensor Port, the Voyager can measure the temperature at the battery in real-time and uses this data for very accurate temperature compensation for both too high or low battery temperature, and thus adjust charging voltage to assure stable and constant charging to the battery. I had seen Ray over at Love Your RV do this upgrade on his 5th wheel, so we were hoping to do the same. step 11 : slippery silliness ! Renogy 40A DC to DC Battery Charger ; Nominal Voltage: 12V: Rated Charge Current: 40A: Output: 500W: Idle Power Consumption: <0.4A: Input Voltage Range: 8V-16V: . This design method can well prevent the starting battery from being over-discharged during the charging process. I am trying to see if it ok to have the 7 pin doing the trickle charge and using the DC to DC at the same time. Do not reverse the polarity since the reverse polarity of the battery connections can cause injury and damage to the device. 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. 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. It has multifunctional safety technology including over-voltage protection, over-temperature protection, and reverse polarity protection to make it safer for use. See photo 5.8. Connecting to the DC+ lug for a light power source that is only powered when the engine is running. Ensure that the maximum charging current provided by the DC-DC battery charger does not exceed the maximum charging current allowed by the house battery. Step 7: mount the breaker to the Truck compartment, and pull the new #4 wire for connection to the breaker. Eddie and I thought it was indeed possible that the specific unit we installed could have been faulty, we had no way of knowing. This means that, all I had to do was run a #4 cable from the shunt, snake it through the existing wiring, and terminate that cable in the back of the DC Charger, on the Input side. Now it was time to test our setup ! renogy dc to dc battery charger 20a, 40a, 60a Victron has many versions available for 12, 24, and 48 Volts. Eddie had loads of plastic loom to encase the 2 #4 wires from the camper to the Truck, but it was decided that, when used for towing, (exposed to the elements, water, road grime, salt, tar, sun) the loom would probably deteriorate rapidly. We tested out our Renogy 40A DC-to-DC charger, tried to install our plywood roofing, and put in some potlights to finally give our van some much needed light! With this in mind, the NLDC-40 features a 600W MPPT solar regulator, unlike the NLDC-25's 375W MPPT.

Hey guys, so I've been meaning to figure out how to properly have my alternator charge my house batteries. Probably when youre towing, the truck battery voltage is higher hence its not happening. Due to afternoon shade and an AC-power heavy dinner (toaster oven, microwave) and heavy use of the 3 DC fans in the camper (it was 93F), we brought our Battle Born batteries down to 54% after morning coffee and a toasted bagel. A RedArc 1240D can do 40 Amps. For added safety to personnel, the DCC12 isolates the input from the output preventing incorrect voltage transmission. This was puzzling to me, since it would seem that a 40amp DC charger wouldnt draw more than 40amps. I wanted something which could be a simple current limited charger for a LFP battery and yet only be on if the alternator was running (D+). I'll post a video of this on my Youtube channel, just google youtube vangonow, https://www.youtube.com/channel/UCqYGzyL-IjKkQRi2IDnbGIw. The VSR also ensures reliable isolation between the starting battery and service battery, avoiding charging interference. It also isolates the input and output to prevent voltage transmission errors and interfere with house battery charging. My search stopped at the Renogy with the DCC50S, not Australian made but, because it was precisely what I wanted and at a sub $350 price (at the time). We chose the 40amp charger, one because it was a little bit cheaper than the 60amp charger, but also, we wanted to play it safe with extra strain on our alternator in the case that we end up using it more than anticipated. Obviously we can change our power consumption habits to adjust to the lack of sun (not using the microwave, not using the electric water kettle etc), but even then, after 3 days with no sun, our batteries start to dip down to low levels.
