Start over

Solar Inverter

Start with the practical fit, then read the table.

Best fit when a 0.24 kW inverter class, battery-ready planning, and backup requirements like supports Sunlight Backup with IQ System Controller 2; battery-backed backup also requires compatible Enphase IQ Battery and system-control components..

Hoymiles HMS-2000-4T

Best fit when a 1.92 kW inverter class, backup requirements like no model-specific backup-power capability verified in reviewed Hoymiles HMS-2000-4T official sources., and Home Assistant or local monitoring goals.

Solis S6-GR1P(0.7-3.6)K-M

Best fit when a 3.6 kW inverter class, backup requirements like no battery or backup output verified; grid-tied string inverter., and Home Assistant or local monitoring goals.

GoodWe DNS G3

Best fit when a 6 kW inverter class and backup requirements like no battery backup output or backup/EPS function documented in the reviewed GoodWe DNS G3 product page or current datasheet; treat as grid-tied PV inverter..

Use this comparison when the choice is no longer just brand, but whether a microinverter layout or a more conventional compact string inverter fits the roof, budget, and monitoring goals better.

Before You Decide

Checks that matter before price.

Match rated power and MPPT layout to the roof, not just the headline inverter size.
Check whether battery-ready really means compatible with the battery path you want.
Look at backup behavior early, because it can change wiring and quote complexity.
Decide whether the vendor app is enough or whether local data access matters later.

Verdict

Choose Enphase or Hoymiles when module-level electronics make sense, and choose Solis or GoodWe when a smaller string-inverter path is the more practical fit for the install.

FAQ

Common decision questions.

Which solar inverter should I choose?

Choose the option that matches your installation constraints and data path first. For 4 solar inverter options, the full table is most useful after you know whether local data access, cloud convenience, backup behavior, solar visibility, or expansion matters most.

What should I check before comparing prices?

Check installation fit, required accessories, official documentation, monitoring platform support, and any unknown fields in the source-checked table. Price is only useful once those constraints are clear.

Can these devices work with local dashboards or Home Assistant?

Enphase IQ8 Microinverter, Hoymiles HMS-2000-4T, Solis S6-GR1P(0.7-3.6)K-M list Home Assistant support in the catalog. Enphase IQ8 Microinverter, Solis S6-GR1P(0.7-3.6)K-M are marked with local API support. Confirm firmware, region, and integration maturity before treating this as a final compatibility guarantee.

Are unknown fields a reason to avoid a device?

Not always. Unknown means the field was not confirmed from the reviewed source data. Treat it as a question for the installer, reseller, or manufacturer before making a purchase decision.

Does the verdict replace the specification table?

No. The verdict is a practical shortcut. Use the table to confirm the exact constraints that matter for your home, especially installation, monitoring, and support details.
