    Hybrid installation of Renogy DCDC with Mppt

    The isolator is used for a seperate Anderson plug installing on the trunk that runs off the “starter” battery. I use it to run a fridge.

    Hybrid installation of Renogy DCDC with Mppt

    An update to my installation. I could not work out why the charger was working when the vehicle was stationary but stopped within minutes of moving. I later realised that the Redarc isolator was also cutting out at the same time so that explained why the Dcdc charger was not working. I fixed it...

    Hybrid installation of Renogy DCDC with Mppt

    Thanks Randy for sending those videos. It answered a few questions for me. I have asked the local Toyota agent to confirm the charging capacity of the battery charger but I am pretty sure I have plenty of margin. The test will be when I connect the 50A charger in my camper trailer.

    Hybrid installation of Renogy DCDC with Mppt

    Correction to my last.. my aux battery is LiPo. I am getting up to the full 30 Amps from the Renogy charger so far so good.

    Hybrid installation of Renogy DCDC with Mppt

    Thanks for the update on the starting tech.. that makes sense. The battery is NiMh. I was surprised about this and it nearly put me off the vehicle (not being LiPo). After doing some research I understand the decision. The vehicle is manufactured in the USA and therefore cold weather performance...

    Hybrid installation of Renogy DCDC with Mppt

    I haven’t confirmed but I believe the fuse to the battery is 160A. There is no alternator but there must be a starter motor otherwise how would you start the gasoline engine that charges the battery?

    Hybrid installation of Renogy DCDC with Mppt

    Yes. Both batteries. This is connected to the start battery as you would do with a non-hybrid setup

    Hybrid installation of Renogy DCDC with Mppt

    I have recently purchased a Toyota Hybrid Hylander (Kruger in Australia). THanks to the 2 metric ton towing capacity this is an adequate tow vehicle to small to medium size trainers. This vehicle has no alternator and chargers the starting battery through a DCDC charger from the main NiMh...

    Recreational batteries and Hybrid vehicles

    Thanks. Good point. I observed on my last setup on. Ford Ranger…that the dc-dc charger (that was connected directly to the battery via a fused link) stopped charging the rec battery (without an isolator) a few minutes after ignition off. I assume host battery protection is a standard feature...

    Recreational batteries and Hybrid vehicles

    I am taking delivery this week if a Toyota Hybrid Kluger (Hylander). I would like charge my 100AH lithium (recreational) battery from the starter battery which itself is charger by a DC-DC charger (no alternator). Do I need to connect through another DC-DC charger? Solar input would be an...

    Renogy 50A DC-DC charger tripping 50A CB

    I would agree. I will look at the xt90 or just jump to the next Anderson plug. Thx

    Renogy 50A DC-DC charger tripping 50A CB

    My Renogy 50A DC-DC charger is doing as it should and outputting just under 50amps when connected to the smart alternator on my Ford Ranger. Because of the voltage difference going in and coming out of the charger, more that 50A from the alternator (closer to 60A). This causes the charging...

    Solar panel over voltage

    Perfect Thankyou!

    Solar panel over voltage

    I inherited an unbranded solar panel when I purchased a camper trailer. Connected to a Renogy 50A DC-DC charger I measured 36volts at the panel which exceeds to solar input upper limit of 25.5volts. The over voltage protection cut in. My question is, could I use a buck converter to step down the...
