1. 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. 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). This means, (in theory without any loss over the cabling runs), the DC-DC Charger can provide up to 480 watts of charging power to our batteries (40amps x 12 volts = 480watts). The compact and robust design makes it suitable for all conditions. This 20A DC to DC Charger is designed to charge secondary batteries while driving using the primary battery connected to the alternator. I then bought a wirthco battery doctor, but then found out that is not really designed for deep cycle batteries. If you have any questions, please contact us in time. However, these batteries cost about $900 each !

Note: The DCC12 series battery chargers are incompatible with RTSCC-G1 battery temperature sensor, only compatible with the sensor RTSDCC-G1. We had the opportunity to test our setup yesterday. Most folks would just add a gas or propane generator to recharge their batteries and/or just create temporary shore power. Eddie suggested the Anderson connectors (and boot covers), pictured below, for the connection between the Truck and the Trailer. Please allow up to 1 to 2 business days for processing and 3 to 5 business days for shipping. 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. This one took a few more steps to complete after the fact than normal. 1. The DCC12 Series battery chargers are the most effective way to charge your auxiliary or house batteries from the alternator/starter battery. step 10 : connect the long #4 wire from the tail of the truck to the breaker in the engine compartment. Make sure that the plug cannot tough the post by pushing it down out of the way. This multi-stage, multi-input battery charger can charge a service battery from a starting battery linked to an alternator or by utilizing solar panels connected directly to the unit. 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. It has multifunctional safety technology including over-voltage protection, over-temperature protection, and reverse polarity protection to make it safer for use. The DC-DC battery charger isolates the input and output to prevent voltage transmission errors and interfere with house battery charging. Note: Our product department found that there are some errors in the paper manual attached to the battery charger sold before March , and now the manual on the website has been updated. Of course, this step got repeated a few times on the cabling on the Truck and inside the camper, just showing his current method. 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. CaptainMitch. Is it necessary? Hey guys, so I've been meaning to figure out how to properly have my alternator charge my house batteries. Renogy's DC to DC charger packs all the same capabilities as any other manufacturer's, at a lower price point.

Easily install the compact yet sturdy DC-DC battery charger on RV's, commercial vehicles, boats, yachts, and many more applications! This means, (in theory without any loss over the cabling runs), the DC-DC Charger can provide up to 480 watts of charging power to our batteries (40amps x 12 volts = 480watts). Polycrystalline panels are cheaper, but they are also less efficient. These six charging voltages meet the requirements of lithium batteries and lead-acid batteries in order to provide more charging options. Please note the D+ Ignition Cable is not included. The all-in-one NEG- terminal with partition design integrates the terminals for solar panels, the array starter battery, and the house battery, avoiding misconnection and making the simple installation. Following that install, weadded another 200 watts in april 2018. If you have any questions regarding this product, please submit a case. Required fields are marked *. In the picture below, was the existing setup done by Eddie back in the Summer of 2017, showing all the DC loads and Trailer Frame Ground coming in to the left side of the shunt. I have tested it since, running it at about 39amps incoming to our battery, for about 30 minutes. The new ground wire was working as expected, and the red dc wire was turning on the DC unit. This was his first time installing a DC-DC charger in a towable camper, but he was up for it. 4.1 Mount the Battery Charger 4.2 Location Considerations 4.3 Connecting Temperature Sensor 4.4 Connecting IGN Signal Wire 4.5 Connecting Battery Voltage Sensor 4.6 Selecting the Battery Type 4.7 Connect the Battery Charger 4.8 Typical Setup 4.9 Cable and Fuse Sizing 5 Operation 5.1 LED Indicators 5.2 Charging Logic 5.3 Solar Charge Algorithm How do I set the battery since there is no display screen?

It also isolates the input and output to prevent voltage transmission errors and interfere with house battery charging. See owners manual for more details. Brian, this is exactly what I am trying to do. Disconnect the main battery - This wasn't so easy, there is a small (5\" x 5\") plastic cover to the right of the accelerator pedal, pull it from the top and then pull up hard, its not easy bu t it comes off. step 11 : slippery silliness ! High-quality DC-DC chargers are three-stage chargers. While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first! It accepts and regulates a charge from either (or both) your starting battery (alternator) and solar panels, acting as both battery isolator/charger and charge controller. Its only when we are socked in for a few days in a row with absolutely no sun in sight that things start to run a bit thin.
