    Figure out what you need before you buy damn it.

    Folks have different ways of learning and trying new things. Some like to be "hands on" from the beginning - learn by doing - try it and ask questions later. Sure, they will make mistakes, trial and error costs more money, they may get frustrated. But not everyone implements new stuff...

    Best sequence to connect 12 to 48 volt DC to DC converter from car battery to Ecoflow Delta

    As I replied above, it will not be charging without the engine running and being monitored. The Delta automatically reduces the rate of charge to zero as it approaches 100%. I'm not sure of the value of fusing each side of the converter. The converter has a variety of built in protections as...

    Best sequence to connect 12 to 48 volt DC to DC converter from car battery to Ecoflow Delta

    No remote turn on. It will not be running when I am not monitoring the system. Since it is feeding the solar input of the Delta, the Dekta reduces its input as it approaches 109% charge.

    connecting inverter with the renogy 50 amp dc to dc HELP!!!!!

    In my case, I'm using a DC to DC "converter" to bring 12 volts from my alternator in my car up to 48 volts, and 40 amps from the alternator down to 10 amps to charge, in my case, an Echoflow Delta, to charge it up quicker. I'm wundering if the OP might be concerned that he blew out his...

    Best sequence to connect 12 to 48 volt DC to DC converter from car battery to Ecoflow Delta

    What is the best (safest) cable connection sequence to connect a car battery to the Ecoflow Delta through a 12 to 48 volt DC to DC converter? I understand the car should be running either prior or soon after connections are made. See photo of device to be connected:

    How much solar power should I expect from 500W panels

    About 75% of their rated value. ~4000 watts. Sort of like the quest for perfection: Most of us hope to approach it knowing the impossibility of achieving it.

    Bypass diode sources and how to spec them...

    Yes, two. I just want to be versed in how to test and have spares if I need them.

    Bypass diode sources and how to spec them...

    Can diodes be tested in line or do the have to be removed from the circuit?

    Bypass diode sources and how to spec them...

    So NMNeils suggestion of 100 volt diodes is inappropriate? I also thought that I would need at least 65 volts. I looked at a bunch of sources for 65 volt or greater Schottky diodes. I couldn't find anything more than 45 volts at 10 amps. I wonder if anyone even makes them.

    Bypass diode sources and how to spec them...

    Thanks. I went to that link. None of the photos, no matter which of the 1,000 combinations of Schottky variables I select, look like my diodes. This was my result from doing a search on the Mouser site...

    Bypass diode sources and how to spec them...

    What is a good source for bypass diodes? And what is the best way to spec them for a specific panel? For example, if a panel is ~21 volts, 3 in series, each 11 amps, rated at 200 watts? I've searched several electronics suppliers and I don't notice anything that seems appropriate. Can anyone...

    Diode spec for 200 watt panel

    Does anyone know, for a 2-diode panel, what the diode specification should be for a 200 watt, 21.5 volt, 11 amp panel?

    Wire gauge from vehicle battery to DC to DC converter

    Thanks. I'm going with 8 gauge.
