Samlex Inverter Power Draw Question

BTW upon re-read, 6000 watts is ample surge wattage, but 8ms is equivalent to about only 1/2 of a half of a full sinewave cycle (i.e. 1/4 of a full cycle), meaning that the surge rating is relatively meager, which is a reflection of the inverters inner-workings…Per my previous (bargain inverters…) recall that ‘advertised wattage ratings’ is only part of the story, and when it comes to ‘heavily reactive’ loads (e.g. compressors and microwaves), surge ratings and duration matters most because these loads tend to ‘push back’ against the power source (your Samlex)…I would also consider running a second set of cables (in parallel) to your existing 02’s to help minimize voltage sag (say, under heavy loading), and for possible future use - FWIW, to my ProSine 2.0 I’m running 0004 AWG cabling, 6’ roundtrip… JMO…

For example the ProSine 2.0 (2000w) has a surge rating of 4500w and a duration for 5 seconds (does run my 11kbtu air cond without a hitch…), while even 20 seconds in not uncommon on say a heavy, old school copper-transformer based ‘Low frequency’ inverter…

Just a heads up: Considering your desired usage, for your next inverter you might keep in mind a true load sharing type, combination inverter-charger…Personally (in this regard…), my next ‘someday’ inverter will likely be a Victron multiplus hybrid (true load sharing type) inverter-charger…
