Hoymiles HMS-2000 Series 208V Solar Microinverter

What it does: Converts DC power to AC at the panel level — one unit connects up to 4 solar panels, each with independent power tracking, so shading or mismatch on one panel doesn't drag down the others.

Key specs:

• Max AC output: 1,440W | Output voltage: 208V AC
• Module inputs: 4 | Independent MPPT channels: 4
• Max DC voltage: 65V | Max input short-circuit current: 25A per input
• DC/AC ratio: up to 1.5:1

Built for: Residential rooftops, commercial solar projects, carports, multi-orientation arrays, shade-prone installations

Why it matters:

• Independent MPPT per panel = each panel performs at its best regardless of shading or orientation differences
• 4-in-1 design = fewer units needed, lower installation/balance-of-system costs vs. one-microinverter-per-panel setups
• Built-in rapid shutdown = compliant with NEC 2017/2020 and Canadian CEC 2021 code requirements
• Sub-1G wireless = longer range, more stable than older 2.4GHz Zigbee systems — good for large or commercial roofs
• Module-level monitoring = easier troubleshooting (Hoymiles DTU Pro S gateway required for monitoring)

Compliance: UL 1741, UL 1741 SB, IEEE 1547/1547-2018, NEC and CEC rapid shutdown standards

Compatible panels: High-power 78-cell and 156-cell modules
