The only functionality it’s missing is an LCD screen or Bluetooth to display charging levels. This is a good design because the device switches its 50A capacity between whatever charging source is working for you at the moment. Vice versa if you aren’t driving and there is lots of sun, 50A can come in from the solar. This is not mutually exclusive – for example, if there is no solar coming in, then it can pass up to 50A from the alternator. There has been some confusion on the specs, so we confirmed with Renogy. It can function with up to 660W of solar panels (that’s a lot!), and any vehicle alternator. The solar and alternator capabilities of the DCC50S have standard specs that match those from any stand-alone equipment. It will even trickle charge your vehicle battery once it senses your house (solar) battery is full. If designing our system today, we’d definitely buy the Renogy DCC50S. Traditionally the charge controller and B2B charger were two separate pieces of equipment. What’s cool is it’s a combo Solar Charge Controller and DC to DC Vehicle Alternator Charger. This thing wasn’t out yet when we designed our electrical system in 2018. We’re excited by the new DCC50S Charge Controller MPPT from Renogy. But you do need to be near an outlet (no boondocking). Shore Power: Plug in to an outlet to charge your batteries! No sun or driving necessary.

Depending where you are for the winter, they might happen a lot. Solar panels are trying to generate energy all day, while the alternator only works when the engine is on. Compared to solar panels, it’s pretty limited.

A 15-minute drive isn’t going to be much energy. Alternator:The vehicle needs to be running for quite a while to get a meaningful charge from the alternator.You will also need to consider all the potential issues with the three main charging options: A budget setup for off-grid electricity could be just a battery to battery charger and a 12V battery. If you drive a lot and don’t consume a lot of electricity. Depending on your usage, you might actually be able to skip solar panels altogether.If you solar panels can’t keep up with your demand, the alternator can make up the slack. Simply, for battery health you want to charge your battery to 100%. Alternator charging can increase the lifespan of your battery.You’re going to have a charge controller anyways, and the combo devices are only a bit more expensive. If you’re designing a new electrical system, we definitely recommend charging from the alternator. Combination charge controller & alternator chargers (like the Renogy one we recommend here) are now available. There’s some newer products that make this whole thing a lot easier.For 400 to 600 amp devices, click here.How do you live your life on the road? The benefit of alternator charging is directly proportional to the time spent driving. Click here for single rectifiersand click here for dual rectifiers up to 300 amps. Each is designed for use with multiple batteries and how you plan on using your DC resources will dictate which device is the appropriate choice for your application. We manufacture battery isolators in two configurations: single rectifiers and dual rectifiers. With heat being the primary killer of electronics, engineering heat OUT of the product yields unparalleled reliability. Unlike conventional silicon and Schottky isolators, POWER-GATE’s achieve sub-100 micro-ohm performance, even as the currents climb through 600 amps that’s over 1,000% more efficient than traditional silicon and Schottky technology. Recommended by EnerSys (manufacturer of Odyssey, Hawker, Loadhog, Powersafe, General, NP, Ironclad, Genesis, Heritage, and Varta batteries), and utilized in both military and civilian applications, POWER-GATE battery isolators ensure that power gets to where it’s needed without the excessive heat and voltage drop typified by more common, lesser performing silicon and Schottky devices. POWER-GATE devices enjoy ultra-low on-resistance and require no heat sinking and no airflow at currents up to 600 amps. Never confuse conventional battery isolators with POWER-GATE battery isolators. They are commonly deployed in multi-battery applications where independent discharge or battery separation is required.

POWER-GATE Battery Isolators are industry leading, high performance, one-way electrical valves. Implementing a robotic assembly technique, an “ideal diode” is created. In 2005, Perfect Switch developed and internationally patented a concept we call “high ratio geometry” where we array large numbers of semiconductors called MOSFETS.
