Chargeverter maximum amps

[Dralkyr]

I have the chargeverter hooked to a Honda EB 5000. The chargeverter itself allows amp settings up to 100, but the supplied plug is a 30amp plug. Can I use a higher setting on the CV, or keep it to 30?

Also, do I need to charge with 240v or can I charge in 120v mode from my generator?

Input current is at AC volts. Output current is DC volts.

56V * 100A = 5600W

5600W / 240V = 23A

120V will not deliver the full 100A output.

EB5000 is rated for 4500W, so I wouldn't run it above that.

4500W/240 = 18.75A
4500W/120 = 37.5A

You need to limit the chargeverter to 4500W/56.8V * 85% efficiency = 67A

Suggest you RTFM as these are addressed in the manual, and you need to rewire the plug accordingly for 120V or 240V.

Sorry, apparently I'm stupid.

With a 5000 generator at 240v, what's the highest charging amps I can use? 80-85 or something?

It's a common mistake.

Answered above. Repeated below.

You edited your answer after I started replying, so your first answer didn't show up.

The manual, as far as I can tell, does not cover this concept. All it says is that the maximum DC output current with 240v/26a is 100, not how to calculate what one should actually use.

It covers the need to rewire the cable for 120V use.

Yes, it does. The generator phase the correct plug and output for 240. Thank you for the calculations

if the above was confusing let me suggest a very simple way to find out how much you can pull form your chargeverter.

if you are powering it with 208-240 and your genset can put out 30 amps do not worry let it rip. if it does not and you want to find out what your max is lower it to say 60 percent turn it on and then at 5 minute intervals bump it up by 5%. when the genset starts stumbling back it off by 10% and you are done.

if you are powering it with 120 it has an upper limit of 50% of its 240 output so its max limit would be 50 amps start it at about 25 amps out put and start ramping it up the same as above. keep going until it stumbles, or you hit the aforementioned 50 amps of output. in this mode just because it can put out more than 50 amps does nto mean you should, its there for overheating protection.

you are limited by either the output of the genset in volt amps, or by the output voltage. you are looking for what the genset can sustain, not the chargeverter.
