Upgrading From 6000XP to 12000XP V1 and V2

Today I'm swapping out my three EG4 6000XP inverters for two EG4 12000XP inverters, including a V1 and V2 running in parallel. This video covers the full teardown, reconfiguration, wire sizing, breaker selection, NEC code compliance, and commissioning from start to finish. If you're considering upgrading from the 6000XP to the 12000XP, this is everything I learned doing it myself. Topics covered: Safe shutdown and disconnection procedure Battery reconfiguration for the 19.75" clearance requirement Wire sizing: 3 AWG THHN for line and load (where to buy, how much, color coding) Breaker selection: 100A Eaton BR breakers (Amazon vs Lowe's pricing) EG4 12000XP V1 vs V2 parallel compatibility Conduit box modifications for the wider 12000XP AC wiring with color-coded THHN Parallel communication cable setup Commissioning and first power-up EG4 12000XP at Signature Solar (affiliate link): https://signaturesolar.com/eg4-12000x...
