Hoymiles HMS-1000 Series 2-in-1 Microinverter

Hoymiles HMS-1000 Series 2-in-1 Solar Microinverter

What it does: Converts DC power to AC at the panel level — one unit connects up to 2 solar panels, each with independent power tracking, so shading or orientation differences on one panel don't drag down the other.

Key specs:

• Max AC output: 638W
• Module inputs: 2 | Independent MPPT channels: 2
• Max DC voltage: 60V | Max short-circuit current: 20A per input
• DC/AC ratio: up to 1.5:1
• Supports up to 9 units on an AWG10 trunk cable (fused at 30A)

Built for: Residential rooftops, commercial solar projects, agricultural and small business installations, solar retrofits

Why it matters:

• Dual independent MPPT = each panel performs at its best regardless of shading or mismatch
• 2-in-1 design = faster installation, less wiring 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
• Module-level monitoring = faster troubleshooting

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