I would guess that this is when your Inverter/CHARGER cuts in to keep your batteries charged. The charger portion of your inverter can draw a lot of power and cause a momentary surge in amps needed. ON my inverter the charging rate is adjustible, or can even be turned off entirely.
You need to rethink how you think your INV/CHR operates. It does NOT operate like you posted. Yes, it goes to hi amp BULK charge when 120 volts is applied to it. BUT, it tests the battery state and depending on the charge of the batteries will go from bulk to mid charge to float charge, usually pretty quick. Now, when Camping, the Inv/Chr will NOT go to a bulk rate again. It will constantly supply a charge to the batteries (Float) and IF you have a hi draw appliance activated(M/W), then it may ramp up the charge rate a little but not to bulk. The Charge rate you can set is basically for that initial 120 volt connection to limit the 120 amps on BULK charge. There are other parameters, but you need to research the operation manual for your size and Brand Inv. Doug
