Solis S6-EH3P20K-H-EU — a 20 kW three-phase hybrid inverter with 4 MPPTs, high-voltage battery support (120–800 V) and <10 ms backup switchover. Delivers 97.7% max efficiency, IP66 protection, intelligent fan cooling and full SolisCloud monitoring for scalable residential and light-commercial storage.

The **Solis S6-EH3P20K-H-EU** is the top model in the S6 three-phase hybrid line, built for larger homes and small businesses that need high power, fast backup and smart energy control. It combines PV, battery and grid in one system, supports **160% PV oversizing** (up to **40 kW array / 32 kW usable**), and works with **high-voltage Li-ion batteries (120–800 V)**. With **4 independent MPPTs**, installers get flexible string design and strong performance across roof orientations.

Backup mode delivers **1.6× rated power for 10 s** with **<10 ms** transfer — effectively UPS-like continuity during outages. Efficiency reaches **97.7% (EU 97.5%)**, and the unit is engineered for demanding sites: **IP66**, **intelligent fan cooling**, **–25…+60 °C** operation and **parallel expansion up to 6 inverters**. Connectivity includes **CAN/RS485/Ethernet** (Wi-Fi/LAN/4G optional) with **SolisCloud** app for monitoring, TOU charge/discharge scheduling, and VPP/EMS integrations.
