Thanks for the feedback. I have fuses in between (300A between inverter and battery, fused between battery and converter, etc).
If I run 2/0 between the inverter, the post and the battery bank, wouldn't I also need to run 2/0 on the battery inter-connects?
I checked the inverter manual, it recommends maximum run 6' of 1/0.
Typical use of the inverter is run TV, coffee maker and very occasional use of MW. Inverter is already ok with coffee maker on 6' of 1/0 (cables I ordered with the inverter), but the MW cuts off almost immediately. I suspected this was due to the lighter gauge battery inter-connects I have now (2 gauge). Inverter is a pure sine 2000 capable of boosting to 4000, so I thought this would be sufficient for the MV.
