Hi, I'm looking to upgrade my system and looking at either two EG4 18kpv or two Victron Quattro 48/10000 with the Smart Solar MPPT RS 450/200. Going with Victron system seems like the more robust option in terms of powering loads and surged capacity, although it will cost slightly more and has less PV input power. Signature Solar's videos show the EG4 18kpv shuts down a little over 60 amps AC output per phase. The Victron 48/10000 is rated to surge at 20000 watts, which would be 166 amps single phase. Two units (you need two for split phase) would surge at 40,000 watts. The Victron manual recommends a 400 amp DC breaker for the 48 volt battering input. Part of me really just wants to spend the extra couple thousand on the Victron units and have peace of mind.
