Best Single-Phase Solar Inverter for Home Solar: 5 Compared

The Deye SUN5/6/7.6/8KSG01LP1US line covers four power tiers — 5000, 6000, 7600 and 8000W — from a single hybrid platform, so the same enclosure fits a modest roof or a heavy-consumption household with low-voltage battery support already built in. Two MPPT channels track a 150-425V range, wide enough for panel strings that aren't perfectly matched. Efficiency runs at 97.6% (96.5% Euro-weighted), and a TYPE3R enclosure combined with a -40°C to +60°C operating range means it tolerates an uninsulated garage or an exposed exterior wall without extra protection. At 30kg it's the heaviest inverter here, the trade-off for packing charge controller and hybrid electronics into one box.

The GEN24 5.0 Plus outputs a flat 5000W and pairs a 230-530V MPPT window across two channels with the widest operating range in this group, -40°C to +60°C, inside an IP66 enclosure rated for direct outdoor mounting. The "Plus" designation is Fronius's battery-ready platform, so a system installed as string-only today can add storage later without swapping the inverter. Efficiency sits at 97.6% (96.3% Euro-weighted), essentially matching the Deye above it despite the transformerless topology. At 15.38kg it's roughly half the weight, which matters for wall-mount installs where structural loading is tight.

At 12.0kg, the SUN2000-3.6KTL-L1 is the lightest inverter in this comparison, and its 98.4% peak efficiency (97.8% Euro-weighted) is the highest measured here — a real difference on a residential system where every conversion point costs output. Two MPPT channels cover a 90-560V range, the widest span in this group, giving more flexibility in string sizing and a lower start-up threshold for shaded or partial-sun conditions. Rated output is 6000W with an IP65 enclosure. It's a pure string inverter with no integrated battery support, so it suits a straightforward grid-tied residential install rather than one planned around storage from day one.

The SE6000H is rated for 6000W of continuous output, matching the Huawei above but built around SolarEdge's HD-Wave topology, listed at a 99.2% peak efficiency (97.5% Euro-weighted) — the highest peak figure in this comparison. It ships in a NEMA 4X enclosure, a higher outdoor/washdown rating than the IP65/IP66 figures elsewhere on this list, useful for exposed coastal or high-moisture mounting locations. At 11.9kg it's close to the Huawei's weight class. HD-Wave architecture pairs with module-level power optimizers rather than relying purely on inverter-side MPPT, a different approach to partial shading than the string designs above.

The DNS G4 is the lightest and most compact inverter in this group at 9.2kg, with a max output of 6600W across two MPPT channels drawing up to 26A of input current — a higher input current ceiling than the Deye or Fronius units above. Efficiency is rated at 98.1%, competitive with the Huawei despite a shorter published spec sheet. An IP66 enclosure covers outdoor mounting. GoodWe publishes fewer figures for this model than the other picks here, so treat it as the compact option for a straightforward single-phase residential install rather than the one to compare on architecture or thermal range.
