I found a supplier for a 500 W, 12 VDC to DC converter, where you can select the output voltages: 24, 30, 36, 40 and 48 by setting DIP switches. I have ordered one for myself to test it. Since I am seeing this as new, I can only suggest this to anyone who wishes to change their Bluetti battery from the 12 VDC auto supply through the PV port at a higher voltage. It is just a board and need a case and cabling, so it is a DIY device, not for those who just want a ready to plug in device. Its regular price is $55.99 but the special price is $23.96 plus shipping (you select it at checkout). Payment can be done through PayPal.
Please post if you placed an order so I know who ordered it. Then we should return and post here the result so others can decide if they wish to buy it.
As I wrote above, this is a suggestion and I am not responsible if it does not work for your need. It was developed for car audio specialists who need higher voltages for special high power amplifiers, which are also sold here. This web site has other items for DIYers in audio and other devices. Just look around.
Is it safe to use? How much amps does it pull? arent those solar input have Voc and Isc requirements?.. I see it is a lot cheaper than buying a Pecron 500w charger but Pecron already a known brand and has been tested to work with some bluetti products
The base math is 500W / 12.8V (12.8 being the average input voltage from a vehicle) This = 39A.
There will likely be efficiency losses similar to inverter losses, give or take around 10%. So, it’s basically a 40A power supply, that will need cabling and fusing similarly sized to 40A DC-DC charger.
The one thing not mentioned in the device specs is current regulation in amps, or how clean the output power will be. It does mention an oscillation frequency in its specs.
However, for the price worth a test. I would test its output with a power meter on a load other than your power station, just in case and preferably with an oscilloscope.
Well, its designed to get connected to a alternator for voltage input 12V - 14V. But there are two things that could make this difficult. First is, how you want connect two high power DC sources to your AC200Max? You cant just put them together when they deliever different voltages and current. Second, might be even more important, i dont think that any alternator in a car can handle like 1000W+ output, supply the car with energy and also charge the 12V Battery.
Mine. It is a 2014 Ford Fusion Hybrid (HEV). The main
electric motor is also a high voltage generator which uses regeneration to charge when braking (the pads are hardly used, and it still has the original factory installed brake pad set after ten years). The 12V battery is charged with a DC to DC converter, so it has no alternator. A second motor/ generator starts the gasoline engine with a static clutch when needed. The Energi model is a PHEV, and has a larger battery.
It is a marvelous vehicle, but Ford make a grave mistake cancelling it in 2021. Consumer Reports classified the Fusion Hybrid as one of the best used cars.
