i think there is a little confusion

PT or one of the other magnum ownwers can correct me

but i think IF you set the shore power at 15a or any given amount

the magnum monitors the loads on the pass thru
if you turn something on, it will reduce the amount of charging power used
to keep total power within the the limit you set

but it is NOT an automatic 5amps of 120v use, that would only be a 600w aka 45amp charger

and that is NOT how it works

That's how mine works. The charger will use as many AC amps that are available, staying under the limit.

Hybrids might be a little different?

this is how I understand the hybrid to function. if it's detects a load while on 15amp shore setting and charging, like for AC for example, the "shore max" setting will cause a reduction of charge function and instead allocate to the load. if the load exceeds 15amps, then it will kill the charge and combine the 15amps from shore with whatever needs to be inverted from the batteries to service the AC load (called Load Support ACC on my panel, which will not allow more draw from the AC source than its set to). when the AC load terminates or drops, it will resume charging, allocating the 15amps, less any residual loads. it works in parallel to incoming loads. it does monitor the AC flowing through it, to the extent that flow is fed by the inverter (sub panel)

I can plug into a 30amp pedestal, then turn on the AC unit, and it will pull 30 on the pedestal and invert the balance to run the AC. when I turn off the AC, the charger becomes active and fills the batteries, with whatever is left over after servicing a load, if any.

lots of variability with the hybrid

I read the manual yesterday and will look again, but I think this is correct.

Hi outwestbound,

Yes, your interpretation of the manual is correct. I don't have a sub panel--I power the entire rv via the Magnum. I can wire around it if need be. The Magnum doesn't like most GFCI outlets, hence the need to "bypass" it.

Gordon Three,

The only difference with the hybrid units is the ability to draw energy from the battery bank to make up for power over loads. The feature is called load support (but it is NOT voltage support).

It will take longer to get from what you started at to what stopped at for SOC. Nobody goes over 90% SOC on generator (as was mentioned several times).

You need to figure out your scenario that gets you shore power long enough, often enough, between sessions off-grid, to get to 100% and so to keep going some more off-grid. Or park in never-ending sunshine.

Oops this may be in the wrong thread.

Thanks to all for your help!! I did not know how to use my generator properly in conjunction with my solar and now I do.

Just a note - When a single battery droops down to 8 amperes charge acceptance...

Four batteries will be accepting 32 amps

Yes it is a compromise

But no denying a stored ampere hour is a stored ampere hour

I don't understand what you mean?
