PV Inverter Advantages
Multiple MPPT Trackers
Single-phase models from 4.4kW upward and all three-phase models ship with dual or triple MPPT trackers. This means strings facing different orientations, shaded by chimneys or trees, or installed on different roof planes can be tracked independently — maximizing energy harvest where a single-MPPT inverter would lose production to the weakest string.
Wide MPPT Voltage Range
Three-phase inverters support up to 1100V DC input with an MPPT window of 140–1000V, allowing longer string designs and fewer combiner boxes. Single-phase units cover 50–550V, making them compatible with both new high-voltage modules and legacy 60-cell/72-cell arrays.
Integrated Surge Protection
Every inverter includes Type II/III surge protective devices on both the DC (PV) side and AC (grid) side, reducing additional balance-of-system cost and installation time. Built-in anti-islanding protection and reactive power support comply with major grid codes.
Pairing with Storage
Our PV inverters can be combined with HLY-DLS residential storage or HLY-ELS C&I storage to form hybrid self-consumption systems. For residential projects, the all-in-one HLY-DLS hybrid inverter (7kW PV input, 10ms backup transfer) integrates PV MPPT and battery conversion in a single enclosure.
