GoodWe ET Plus 5kW Hybrid — Ireland 2026
Maximum battery flexibility — LG Chem RESU and most major brands
The GoodWe ET Plus 5kW has the widest battery compatibility of any hybrid inverter in this directory — supporting BYD, Pylontech, Alpha ESS, and LG Chem RESU alongside its own batteries. This makes it the right choice for homeowners who want to compare battery prices independently and avoid being locked into a manufacturer ecosystem. At ~€1,000, it sits in the mid-market with a 10-year warranty and backup power capability. The SEMS Portal monitoring platform is well-regarded by Irish installers.
