Hey guys, so I've been meaning to figure out how to properly have my alternator charge my house batteries. Charger Bob L on Jun 23rd 2022 I had our grey water hose, which I was willing to chop, knowing I could replace, re-cap when we got back to town. Similar to the 7pin connector on a travel trailer or 5th wheel (that runs the camper running lights, brake controllers, and actually can send a little bit of dc power to your camper, but mainly for trickle charging at a low amperage), the idea is to run another high-amp connection from the tow vehicle (on an additional / separate cable to the 7pin towing cable) which is capable of delivering much more power directly to a DC charger which is connected directly to the house batteries of the camper. 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). For example, the Renogy 40A DC to DC battery charger may draw up to 60Amps whilst charging (40 amp x 1.50 (50%) = 60 amps). The DC-DC battery charger will charge your house batteries from the starter battery by 3-stage charging (Bulk, Boost, and Float), to make sure it optimally and automatically charge to 100%. This implies that various levels are employed while the battery charges. I verified that, even IF the DC Charger has its red DC ON wire connected to power, the unit will NOT turn on, unless it has incoming DC power. The D+ Ignition cable is a design method used to identify whether the generator is started. 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. 2. I will try and ask Eddie if a smaller gauge wire would work. They are available on Amazon as well as directly from Renogy. For example, a Victron MPPT Solar controller can obtain battery temperature via blue tooth from the Victron Battery Monitor eliminating the need to install a separate temperature sensor for the Solar controller(s). 1.

So I chopped the alligator clips, and these wires had an impossibly small #20 wire. yowza. The Renogy hides the input cables and uses posts to connect the ca. Meaning your panel array can be much larger when using the NLDC-40. This design method can well prevent the starting battery from being over-discharged during the charging process. 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%. Below is a proud Eddie, and his new Load side Anderson connector. Easy to install and well made. here is a closeup of the anderson connector on the tail of the Truck (source) and the trailer side (load) the garden hose connector. If Renogy added this already, or adjusted the charging algorithm to accommodate such scenario (low PV power) it would be perfect. Why it does this, the lithium battery will take the full 50 amps until it reaches 14.4 volts. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); im out at Hartman Rocks, just outside of Gunnison, CO.
