Anyone have any experience / suggestions about this?
It's a perfectly reasonable approach if the inverter has capacity adequate to cover the startup surge (most of them will support a much larger load for a short period of time, than their rated power), and if your batteries have enough power to cover the shortfall (doesn't take much for just a couple of seconds of load).
An even better approach is to use a charger/inverter which has a power boost feature -- which will pass through AC power but supplement this with inverter power when needed to make up short-term deficits. Mastervolt and Victron make these. I have a Victron Multiplus in my boat and it works a treat for this purpose. I don't have air conditioning
, but I can easily pop breakers on 16 amp shore power
circuits if I don't use this feature. I set the current
limit on the Victron and it will not allow the electrical system
to take more than that from shore power
(or generator). It will invert power if someone, for example, switches on an electric
kettle which on top of other loads exceeds shore power capacity. Works great. Would be perfect for air conditioning
startup loads like in your case.
