EG4 12000XP vs Solis Hybrid — Which DIY Inverter Fits?
Two different jobs: the EG4 12000XP is the off-grid / big DIY shop workhorse I recommend for split-phase power and huge PV headroom. The Solis S6 11.4 is the high-voltage hybrid I point to for cleaner grid-tied storage. All items listed include affiliate links.
