Which charger+inverter?

math says the Victron ip22 12/30 pulls about 3 amps AC when charging at 30A 12v DC

My 1012LV-MK has a 60A charger.
The monitoring meter on the ‘incoming’ 120VAC from champion generator is typically 7.6-7.8A or a bit over a quart of gasoline for one hour (60Ah) of charging

Hope that helps.
 
For anyone looking at using the most powerful charger they can using a generator that might not be sized to put out enough power, the Victron multiplus has a current limiter feature that will keep the generator from stalling.

Even though I haven't used it, on paper it sounds like exactly what I need. A generator will lose power when going up in elevation and in my case a Yamaha is2200 is the largest I want to carry around. At lower elevations it should be able to supply enough current for the 120amp charger, yet when I go up to 10k', the current draw can be lowered in the multiplus settings to keep the generator from stalling. See 2.2 Input AC Current Limit https://www.victronenergy.com/live/multiplus_faq

To configure the current limiter, the MK3-USB is needed and a laptop. As an aside, when charging the inverter draws from the AC input so whatever juice is used for the inverter needs to be subtracted from the AC load to determine how much AC is actually used for charging.
 
Fyi, I've been using a Magnum 3000w hybrid inverter/ charger since April 2016 everyday and hasn't been turned off without issue.

It can be set for the ac incoming. If using my EU2000I or eu2200i generator I'll set the incoming to 15a and it will charge the batteries at 100a. Even at elevation of 7,000'.

Depending on the loadsharing it can be adjusted from 5a-50a depending in incoming source. All adjustments are made from the me-arc (remote controller).

Looks nice for lead acid batteries.
 
Using the me-arc it's programmable.

I ordered the Progressive Dynamics 60 AMP charger to cut costs vs the Victron Multiplus and to do separate components.

With the 60 amp converter charging the the pack off the generator, it pulls about 12 AMPS (plus computer gear). Its running at 4k feet now so when running at 10'k feet the generator should put out enough power.

Its temporarily connected with solid copper nomex cables that you'd find in a house for AC. I'm trying to figure out cable lengths and if it would make sense to pay for an Anderson connection setup so that I can charge both the LIFEPO4 pack or my SUV battery.

What SUV would you be charging?

Is the ‘computer gear’ why its using 12A120VAC? Because that seems high for charging 12V at 60A.

The gear probably uses 2A. I'll need to test it out. How much should it use? I really wanted their 80A charger, but it requires a 20A circuit. All I have is 15A and at 10k' more like 12A.

Well my 1012LV-MK does about 8A at 120VAC using its 60A charger.image.jpg

I measured just the draw of the 60A charger and it started pulling 9A, then after a minute or less it leveled off to 7.5A.

The cooling fan stays on for an impressive time after power is pulled from it and I'm wondering if that extra draw surge is to refill the capacitors.
