Hoymiles HYT-10.0HV-EUG110kW three-phase high-voltage hybrid inverter

Overview

The HYT-10.0HV-EUG1 supplies 10000W (11000VA maximum, 10000VA in Belgium) at 380/400V and charges or discharges a 170–600V battery at up to 10000W and 30A. Its second MPPT accepts two strings and 28A, so three strings in total can be connected for a recommended PV array of up to 15000W, with a 1000V input limit. The backup output delivers 10000W continuously and 16000VA for 10s. European efficiency is 97.4%, the housing stays at 26.5kg, and up to 10 units can be combined in parallel.

How it works

HYT-HV-EUG1 inverters manage a PV array, a high-voltage lithium-ion battery and a three-phase 3L/N/PE grid connection. Two MPPT trackers work between 200V and 950V with a 1000V maximum input; the 10.0kW and 12.0kW models accept two strings on the second tracker. The battery port covers 170–600V and follows the BMS over CAN, which keeps currents low: 20A for the 5.0kW and 6.0kW models, 30A for the larger ones. PV arrays up to 150% of the AC rating are permitted.

The inverter supports Self-consumption, Economy and Backup modes and can deliver fully unbalanced output, so a heavily loaded single phase is still supplied. During a grid failure the EPS output takes over in less than 10ms and can briefly supply up to 16000VA. Export to the grid can be limited, and the built-in dry contact can serve as earth-fault alarm, load control or generator start.

Installation and compatibility

The housing measures 502×486×202mm, weighs 26.5kg, is rated IP65 and is cooled by natural convection, with a noise level below 40dB. Mount it vertically or tilted back by up to 15°, leaving at least 300mm above, 500mm below and 200mm at each side. The delivery includes a smart meter with three CTs and a data transfer stick; if the grid-side current exceeds 100A, a meter with larger CTs is needed. Installation altitude is limited to 2000m.

Hoymiles' compatible high-voltage battery list includes its own HB-(10-23)S-G2 and batteries from BYD (HVS, HVM), Pylontech (Force H, Powercube), Dyness, Pytes, Soluna, Sunwoda and others, each with a minimum firmware. The inverters also work without a battery. Listed grid standards are EN 50549, VDE-AR-N 4105, VFR 2019, TOR Erzeuger Type A, RD 647, NTS and CEI 0-21 2019:04, with IEC 62109-1/-2 for safety.

Monitoring and parallel systems

Up to 10 inverters, including units of different power, can be linked in parallel through the PARA ports with communication cables no longer than 10m; termination switches are set on the first and last unit. Each inverter needs its own battery, and the data transfer stick must be connected to the master. Monitoring runs on S-Miles Cloud, while working modes, export management, three-phase unbalance compensation and generator control are set in the S-Miles app.
