The Solis S6-EH3P50K-H is a 50kW three-phase hybrid inverter built for commercial and industrial solar PV and battery storage. It runs on 400VAC at 50Hz and works with a high voltage battery range of 150V to 800V DC, combining large-scale generation, storage and backup power in one unit.

Solis three phase hybrid inverter features

• Output, 50kW rated, 400VAC three phase, 50Hz
• MPPT trackers, 4 trackers with up to 8 string inputs, 20A max per string
• PV array support, recommended array size up to 100kW, max usable PV input power 96kW
• Battery ports, 2 independent ports, each handling up to 70A charge/discharge
• Coupling, DC and AC coupling supported for new builds and retrofits
• Backup switching, less than 10ms, with 160% off-grid overload for 2 seconds

Applications

This is not a residential unit. It suits warehouses, agricultural sites and industrial buildings where a single three-phase inverter needs to manage significant solar input alongside large battery banks and backup loads. The high voltage battery architecture, 150V to 800V DC, keeps operating current lower than a 48V system for the same power, which reduces cable sizing and heat losses across the installation. It is not compatible with standard 48V battery systems.

Flexibility and expansion

Dual independent battery ports let two separate battery strings be sized and expanded separately, giving room for phased installs or redundancy. Multiple units can be paralleled for larger sites, and a generator input is supported for extended backup. The 160% overload rating for 2 seconds covers the starting surge of motor-driven loads such as pumps and compressors without tripping the inverter.

Monitoring and build

A 7-inch industrial touchscreen with Bluetooth and app control sits alongside SolisCloud remote monitoring and diagnostics. The enclosure carries an IP66 rating with intelligent fan cooling.
