Renogy 12V 30A DC-DC On-board Battery Charger with MPPT for Gel, AGM, and Lithium Batteries Using Multi-Stage Charging, in RVs, Cars, Boats, Yachts, Recommended to Match with 40A ANL Fuse

Product Information

This system is ideal for caravans, campervans, motorhomes or boats, where the alternator charging can be shared between the starter and leisure batteries while the engine is running, then the leisure battery can be kept topped up from solar power while the vehicle is parked. Please note: If used with a lithium battery and the BMS shuts down the inputs/outputs to the battery (e.g. in an under-voltage condition), this CTEK unit will not 'wake up' the BMS and so will not be able to charge the battery (this is because the CTEK unit needs to see a minimum battery voltage to commence charging). An external charging source (e.g. mains battery charger, solar charger) will need to be used that can supply a 'wake up' voltage to activate the BMS and allow re-charging. Automatic recognition of generator type is available for intelligent and conventional generators through ignition signals.

If imagine a side effect of lifepo4 on a dc-dc on an IGN feed may be reduced stop/start situations on shorter journeys as the Van's ECU monitors the power drain and compensates by keeping the alternator and engine running longer to keep the starter battery at 80%.d) GST: If and when applicable, GST payable on our products will be set out in our invoices. By accepting these Business Terms you agree to pay us an amount equivalent to the GST imposed on these charges. These chargers are mainly used when you want to use your car alternator as a power source in addition to your solar panels. They are also called alternator solar battery chargers. What is a DC to DC battery charger?

ii. you commit a remediable breach of these Business Terms and do not remedy the breach within 14 days after receiving notice of the breach. The charger will have all battery types flashing and the BULK and PULSE LED lights will remain on for 30 seconds before entering Recovery Mode

The unit isolates the vehicle battery from the aux battery by discontinuing charging after the engine is turned off. In essence, the unit takes power from the alternator and leaves the vehicle battery charged. This is done by not loading the vehicle battery below 12.8V for more than 5 minutes. After 5 minutes if the vehicle battery is below 12.7V the unit will enter sleep mode with all LEDs off. This allows the unit to remain permanently connected without draining the vehicle battery. The unit resumes charging once power is supplied from the alternator. So thinking about it, if running lifepo4 the BCM may be the preferred method, but the SC IGN will also work. Enteligent says its charger’s DC to DC conversion results in 13% energy savings, and direct charging DC bypasses the EV’s internal conversion electronics, shortening charge time.

In countries like the U where the sun is low or never out at all, you need to add a solar power cut off switch, this will fool the charger in thinking its nigh so will go from 50% 25 amps per 50 mode to 100% mode. 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. A 30W to 300W solar panel (PV) may be connected to the unit when camping or as part of a permanent installation. With the panel exposed to direct sunlight, the unit will charge the aux battery using the MPPT function. Note that the open-circuit voltage (Voc) of the panel may not exceed 40V. If the solar input exceeds 45V the unit might be permanently damaged. At night the unit will power down and only power up once the solar input exceeds 13.6V. For faster charging, this unit is best used with batteries up to around 110Ah capacity. For larger batteries please look at our other battery-to-battery chargers. f) Force Majeure: We will not be liable for any delay or failure to perform our obligations under these Business Terms if such delay is due to any circumstance beyond our reasonable control. j) Severability: If any of these Business Terms are determined by any competent authority to be invalid, unlawful or unenforceable to any extent, such term, condition or provision will to that extent be severed from the remaining terms, conditions and provisions which will continue to be valid to the fullest extent permitted by law.I had factory Leisure setup so I have the OEM BCM feed...which works great and dissables the dc-dc during stop/start events. What they found is that charging a lithium battery with a car alternator is not always the best solution. At lower RPM’s the alternator was overheating. This is due to the following facts: One neat thing about the physical design is the screw terminals. They require only a simple standard screwdriver, so they’re easy to connect and disconnect. You don’t have to use any special tools that aren’t already in your toolbox. The terminals are all clearly marked, so they’re easy to read. There are also indicator LEDs to let you know when the charger is active, as well as when Bluetooth is active.

To prolong the life of your alternator and ensure efficient charging, we recommend choosing a DC-DC battery charger that does not exceed 50% of your alternator’s rated amps. Maximum Solar Voc –The open circuit voltage (Voc) is the maximum voltage that the solar panel can produce with no load on it. I am planning to use the Orion 12-112 30A DC-DC charger, but I am not sure if it can take solar panels or not, however as I am installing a regulator in front of the Orion I don’t see why it would differentiate between alternator current and that from my regulator. On the other hand if it also is a regulator it might be a problem. your thoughts and suggestions would be greatly appreciaated. DC to DC battery chargers has custom charging profiles (Bulk, Absorption, and float) for different types of batteries. Bulk, Absorption, and Float stages of battery charging

What would stop us from putting the output from the solar panels (unregulated) into the Orion as well as the alternator and then charging both 12V batteries in parallel from the Orion's output. Allows you to charge your 12V second/auxiliary deep cycle battery on the go, simultaneously from solar and alternator (9-32V) inputs. Provides an advanced 3 stage charging process to produce a safe and comprehensive charge, a must for deep cycle batteries.
