## What matters in a battery-ready hybrid inverter

A hybrid inverter does two jobs a standard grid-tie unit doesn't: it manages a connected battery's charge and discharge alongside converting PV output, so stored solar power can cover self-consumption or backup instead of always exporting to the grid. That combination changes which specs are worth comparing.

Rated and peak power need to match both the PV array and the household load the battery is meant to cover — undersized, the inverter clips on sunny days; oversized, the extra headroom goes unused. MPPT channel count and each tracker's maximum input current decide how the array can be wired: more trackers handle roofs with multiple orientations or partial shading better than one large string, and a higher current ceiling per tracker allows a bigger string before the inverter caps it. Efficiency matters more here than on a grid-tie-only unit, since a hybrid inverter is converting power continuously in both directions rather than only when the sun is out. Enclosure rating and operating temperature range decide whether outdoor wall mounting is realistic, and weight is a practical constraint for anyone doing the install without a second pair of hands.

Only models whose recorded inverter type is explicitly hybrid, with low-voltage battery support, were considered for this list — see below for how the four picks were narrowed down from there.

| # | Model | Pick | Key specs |
|---|---|---|---|
| 1 | [Deye SUN7 6 8KSG01LP1EU 7 68KW Single Phase 2 MPPT Hybrid Inverter LV Battery Supported](https://inverterdata.com/en/deye/deye-sun7-6-8ksg01lp1eu-7-68kw-single-phase-2-mppt-hybrid-inverter-lv-battery-supported/) | Most powerful | 7600 W, 97.6 %, 150-425 V, 230 V, 30 kg, Hybrid |
| 2 | [Deye SUN3 3 6 5 6KSG04LP1EU 36KW Single Phase 2 MPPT Hybrid Inverter LV Battery Supported 2346](https://inverterdata.com/en/deye/deye-sun3-3-6-5-6ksg04lp1eu-36kw-single-phase-2-mppt-hybrid-inverter-lv-battery-supported-2346/) | Best for larger PV strings in this power class | 6000 W, 97.6 %, 150-425 V, 230 V, 19 kg, Hybrid |
| 3 | [Deye SUN3 3 6 5 6KSG04LP1 3 6KW Single Phase](https://inverterdata.com/en/deye/deye-sun3-3-6-5-6ksg04lp1-3-6kw-single-phase/) | Lightest option | 6000 W, 97.6 %, 150-425 V, 230 V, 17 kg, Hybrid |
| 4 | [SMA Sunny Boy Smart Energy](https://inverterdata.com/en/sma/sma-sunny-boy-smart-energy/) | Most MPPT inputs | 230 V, Hybrid |

## 1. Most powerful — Deye SUN7 6 8KSG01LP1EU 7 68KW Single Phase 2 MPPT Hybrid Inverter LV Battery Supported

The Deye SUN-7.6K SG01LP1-EU tops this list on raw capacity: a rated power of 7,600 W and a peak output of 8,360 W, well ahead of the other single-phase hybrids here. It keeps the same 2-MPPT layout as Deye's smaller SG04LP1 units but handles up to 26 A of input current per tracker, so it tolerates a larger PV array before clipping. Efficiency is rated at 97.6% (96.5% European weighted), and the IP65 enclosure with a -40°C to +60°C operating range makes outdoor wall mounting viable in most climates. At 30 kg it's also the heaviest unit in this group — a reasonable trade-off when the goal is running a larger battery bank off a bigger array.

## 2. Best for larger PV strings in this power class — Deye SUN3 3 6 5 6KSG04LP1EU 36KW Single Phase 2 MPPT Hybrid Inverter LV Battery Supported 2346

Deye's SUN-3.6/5.6K SG04LP1-EU sits a tier below the SG01LP1 on power but is built for the same job at a smaller scale: rated at 6,000 W with a 6,600 W peak, still across 2 MPPT trackers. What sets it apart from the other SG04LP1 variant on this list is input headroom — it accepts up to 18 A per tracker versus 13 A on the non-EU version, so it can carry a larger or higher-current PV string in the same power class before hitting a ceiling. It shares the family's 97.6% efficiency, IP65 rating and -40°C to +60°C operating range, at a weight of 19 kg.

## 3. Lightest option — Deye SUN3 3 6 5 6KSG04LP1 3 6KW Single Phase

The SUN-3.6/5.6K SG04LP1 is the non-EU sibling of the model above, with identical rated (6,000 W) and peak (6,600 W) output across 2 MPPT channels, the same 97.6% efficiency and IP65 rating. Where it differs is at the input: it's capped at 13 A of maximum current per MPPT tracker rather than 18 A, which suits a smaller or lower-current PV string rather than a large one. That narrower input spec comes with a lighter unit too — 17 kg against 19 kg for the EU variant — a relevant number for anyone doing a solo wall mount rather than working with a second installer.

## 4. Most MPPT inputs — SMA Sunny Boy Smart Energy

The Sunny Boy Smart Energy is the only inverter on this list with 3 independent MPPT channels rather than 2, worth considering if the roof has three distinct sections — different orientations, tilts or partial shading — that benefit from separate tracking rather than being wired onto a shared string. It matches the group's 500 V maximum input voltage and runs 230 V single-phase output like the Deye units here. Recorded catalog data on this SMA hybrid is sparser than on the Deye models above, so treat the MPPT count and input voltage ceiling as the confirmed figures to compare until more of its spec sheet is documented.
