MPPT SmartSolar 150/45 Charge Controller.Mike’s Victron Energy installation includes the following principal devices: The higher voltage will result in lower cable losses to, and installation cable runs between battery and inverter can be longer, if necessary. This lower amperage greatly reduces energy lost along hot cables. Efficiency, he explains, is greatly enhanced when inverting power from 48VDC to 120VAC because big loads, such as air conditioning, will draw just a quarter of the Amperage compared to a 12V battery system. The main ‘House’ battery now has a paralleled storage capacity of over 30 kWh, and in his excellent video with explainers ( see below) Mike talks us through the advantages of employing a 48V (51V in practise) battery system. His modifications are the result of many hours of planning and forethought. One of the remarkable features of his installation – when you open the RV compartments – is how professional and factory-installed all his enhancements appear to be. He uses a state-of-the-art Canyon Star Toy Haulerfor work and play, on board which he has integrated an enhanced electrical system tailored to his mainly off-grid RV use. We've got another trip coming up in a month or so and am considering pulling the trigger on an Odyssey or Optima battery, mostly out of paranoia.Mike Mas – famous for pioneering drone videography decades before most of us had ever heard of it – has fitted out his RV with a triple-battery system which is turning heads in the industry. I've had two previous vehicles with factory AGM batteries end up with a "dead cell", according to the dealer, and replace the battery sooner than expected. So now I'm wondering if I don't just have a bad battery. Over the last several months since then, (during which time I was considering trading in for an F-250 with dual batteries and alternators and then subsequently almost vomiting at the sticker price) I have been hyper-sensitive to paying attention to how the truck cranks up, with it having a slightly slower crank up a few times since then. So of course after that I thought "To hell with the stuff in the fridge" and turned the fridge off and shut off the disconnect switch for the remainder of the trip, assuming the alternator was just not strong enough to get the job done. What I did not expect was to stop for gas about 100 miles in and have the truck almost not start back up. The result I expected was somewhere between worked flawlessly and the battery on the camper died. Before the trip, I did all the Internet research about if this was possible and read all the comments about "Run a dedicated wire from the truck battery back to the trailer for full voltage/amperage", which I of course didn't do, and "It should work fine but worst case scenario, the trailer batter dies and the fridge quits.". During that trip, I had the battery disconnect switch turned on to power the 12v fridge, mostly as an experiment to see if the truck would keep the fridge going while cruising down the road. The truck had about 20k miles on it at the time. We haven't had it long and I've only towed it long-ish distance (250 miles) once. I have a 2020 F-150 Lariat 5.0 and tow a 26 travel trailer with a standard lead acid deep cycle on it powering a 12v fridge. I have scoured the Internet as much as I can and have not found this topic covered anywhere, including in this forum, so if I missed a previous discussion on this, forgive me.
