HESP 16-20kW
Three Phase Low Voltage Hybrid Inverter
EU | Three Phase | 3 MPPTs
150% Unbalanced-Load Tolerance for Mixed Three-Phase Loads
HESP 16–20kW EU is designed to handle uneven phase demand without requiring all branch loads to remain perfectly balanced. The HESP 16–20kW EU is specified as capable of 150% unbalanced load output for single-phase loads within a three-phase system.
2x Peak Output for Motors up to 12HP
The combination of 2x peak power and a 12HP motor reference gives the 20kW model clear startup reserve for pumps, compressors and other heavy three-phase loads. The HESP48200SH3 20kW model reaches 40kVA maximum peak power and lists motor load capacity up to 12HP.
Dual Battery Inputs for 350A High-Current Operation
Two battery inputs share the connection burden of a high-current 48V system, while the 350A ceiling provides the throughput needed for the 20kW power class. Two dedicated battery input ports give the HESP 16–20kW EU a clearer physical path for connecting a high-current 48V storage system.
Three MPPTs and 1000V PV for Large Solar Arrays
A large PV array can be divided across three independent trackers and longer strings, giving the 16–20kW three-phase system more solar design freedom without concentrating the whole array on one input. HESP48200SH3 accepts up to 30kW of PV input, approximately 1.5 times its 20kW rated AC power.
Scale Three-Phase Storage to Nine Inverters
Parallel operation lets larger three-phase storage systems grow in stages as load demand increases. The HESP 16–20kW EU supports 1–9 units in parallel, so capacity can be expanded while keeping the same three-phase inverter architecture and control platform.
RSD and AFCI Protection for High-Power PV Systems
HESP 16–20kW EU includes dedicated electrical protection functions for the PV, grid, leakage, arc-fault or multi-inverter conditions specified for the model. On a three-phase platform supporting up to 1000V PV and 30kW PV input, these functions add dedicated PV-side shutdown and arc-fault protection.
