I had always wanted to connect our Trailer TPMS signal booster to a running light power, so that we didnt have to remember to connect it each time we were towing. SUCCESS ! The DC-DC battery charger is installed between the starter battery and the house battery. Its a great MPPT Solar controller/DC to DC battery charger. The idea here would be, in our case, to connect the on/off wire to the running lights of the truck, so that it would only be active if our running lights were on (either 7pin connected to the trailer OR we jump the 7pin with a fuse). WIth Built-in Maximum Power Point Tracking (MPPT) technology, this battery charger with MPPT maximizes the solar power when charging from solar panels, and ensures that the loads receive maximum current to be used. Why do we need Smart DC-DC chargers? The RV came with a mechanical solenoid isolator b. They created a ticket for me and put me in the queue and told me a tech would get back ASAP. I have also read some strong feelings against Renogy. 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. We decided to try a DC-DC charger from Renogy. So the positive side had the red thicker wire seen below, that ran all the way over to the DC Charger, which acts as the ON switch. We dont anticipate using this very often (since our Solar is always on), so we wanted to have a way to connect and charge as needed. Opened up the hood of the truck and flipped the breaker to ON which means we were sending power from the truck battery to the DC Charger. step 14 : Well, our travel plans were such that we had to get on the road, even though this install wasnt done. Since we had plans to head down to Arizona in late April 2020, I hit up Eddie Glonek of Mobile Homestead Solar Services to see if he was available to do this install for us. The D+ Ignition cable is capable of identifying whether the generator is started, to prevent over-discharge of the starting battery and protect the generator. Luckily Eddie had a fancy pneumatic ring crimper, perfect for this #4 wire size. If you have any questions, please contact us in time. This manual showed me the two connections points I needed to make on pages 245 thru 248, one for 70 amps of power going to my DC to DC charger located in the rear of the van and the other was a small 12v signal wire that is used to turn the DC charger on ONLY while the engine is running. Compatible with a multitude of alternator types, the DCC12 offers correct charging for AGM, Flooded, Gel, and even Lithium deep cycle batteries! This would complete the Truck positive and ground for the power output from the battery. There are two LED lights above the dip switches, and if it was powered on and working properly, we should have seen a green light on the left side. For RV solar panel installation with limited space, we'd recommend going with monocrystalline panels for the most bang for your buck. Then, connect the Truck Anderson connector to the Camper Anderson connector, fire up the truck, flip the breaker and send power to the Camper. Please allow up to 1 to 2 business days for processing and 3 to 5 business days for shipping. This was puzzling to me, since it would seem that a 40amp DC charger wouldnt draw more than 40amps. B2B chargers are hands down the best way to charge if you drive regularly IMO. Renogy's DC to DC charger packs all the same capabilities as any other manufacturer's, at a lower price point. and charging drops to 6A then back up to 46A every few seconds.

Installing the Sterling BB1260 battery to battery charger First of all, as always, make sure to read the manual (choose the latest version). For the RV system, The generator ensures stable power supply to the starter battery, and uses the extra power of the starter battery to supply power to the house battery. Is it necessary to connect? When the generator is started, a signal will be obtained on the D+ Ignition cable, which will light up the indicator light of the charger. I have a 2018 Winnebago View in which I recently installed lithium house batteries, an inverter charger, MPPT solar controller supporting 4, 100watt panels, xantrex monitor and a dc-to-do charger. The DC-DC battery charger isolates the input and output to prevent voltage transmission errors and interfere with house battery charging. I use a small fan to help it stop overheating. This is a good quality hose, very pliable and wide. The charger is overheating in Scotland in Mid winter and where the charger sits its about 15c and it has plenty of air. 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. We just played phone tag, then email tag (with brief, non-answers to my questions). These are very reliable connectors (used for things like powering winches and snowplows), have a nice weatherproof cover, and are rated for 50amps of power. They take the voltage and current of the input and transform it to a usable voltage/current for the output. 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). 12V 40A DC to DC On-Board Battery Charger.
