Does this inverter support batteries?

No. This is a pure On-Grid model. Storage requires a hybrid inverter (Deye SG03LP1 / SG04LP3 / SG01HP3 series) or an AC-coupled retrofit architecture.

Deye SUN-3/4K-G04P1-EU On-Grid Inverter

The Deye SUN-4K-G04P1-EU is a single-phase On-Grid inverter sized for Georgian residential rooftops where the goal is maximum kWh export and the shortest payback—not backup storage.

On-Grid architecture deliberately excludes energy storage chemistry from the bill of materials. PV modules feed the inverter; surplus energy flows to the utility under net-metering rules while daytime load is covered locally. At 3–4 kW AC, this model matches typical home consumption profiles (B2C tariff ~0.24 ₾/kWh) and avoids the CAPEX multiplier of hybrid hardware when blackouts are acceptable or rare.

Two MPPT trackers allow split-array layouts—east/west roof faces or partial shading—without sacrificing harvest. Export limiting, reactive power control, and Wi-Fi/App monitoring are standard commissioning steps. Grid measurement is typically local to the inverter; extended meter runs (>30 m to the utility point) may require external RS485 or PLC metering—same discipline as hybrid systems, minus the DC energy storage plant.

For installers, the G04P1-EU series is the lightest integration path: AC coupling only, no BMS CAN, no SOC balancing. Pair with monocrystalline or bifacial modules sized to stay within inverter AC nameplate and grid connection limits issued by the distribution operator.

Ideal for

✓ Homeowners optimizing ROI under residential net metering
✓ Installers needing a proven single-phase Deye SKU with minimal commissioning complexity
✓ Properties with moderate daytime load and no requirement for island backup

Technical FAQ

Does this inverter support energy storage units?

No. This is a pure On-Grid model. Storage requires a hybrid inverter (Deye SG03LP1 / SG05LP3 / SG01HP3 series) or an AC-coupled retrofit architecture.

What payback should a homeowner expect in Georgia?

Depends on self-consumption ratio, module cost, and tariff. On-Grid avoids energy storage CAPEX, often yielding the fastest simple payback when most generation is self-consumed or credited under net metering.

Can I upgrade to hybrid later?

Yes via AC Coupling: a hybrid inverter on the GEN port can govern an existing On-Grid string. Plan export limits and meter placement during the initial design.

Single-phase limits for larger homes?

Above ~4 kW AC or heavy three-phase loads, step up to three-phase On-Grid models (SUN-5-15K-G06 or higher) to balance phases and avoid neutral overload.
