I'm also wondering if its surge capacity, 3900 watts for five seconds, 3800 watts for 30 seconds would be enough to handle the inrush current for a 15K BTU A/C.
I believe that surge capacity represents the amt of power generated from the batteries, so in a CG with low voltage, it **may** help with the AC since it will be additive to the shore power being provided.
As I understand it, these will not *fix* low voltage though. They will syc with the shore power (or generator) signal and add current, so if the shore power voltage is low it will allow you to have more power, but will not "fix" the low voltage.
If you have a small generator, I think it would "fix" the voltage, by allowing the gen unit to recover(from compressor startup) since the load that is bogging down the gen is reduced because of the current supplied by the inverter.
In the cg low voltage case, the source isn't likely to "recover" from just your inverter helping.
Magnum tech support is very good. I would send them an email explaining exactly what problem you're hoping to solve and they should be able to give you some insight as to what to expect.
