The price of the Deye SUN-S130/160/180/200/220/225G4-EU-Q0 micro-inverter series in India typically ranges from ₹15,000 to ₹42,000 per unit, depending on the power rating (1.3kW to 2.25kW) and the vendor/distributor.
How the SUN-S Series Differs from the SUN-M Series
- SUN-S Series (2 MPPTs): Designed with 2 MPPT trackers serving 4 panel inputs (inputs are paired 2:1 internally).
- SUN-M Series (4 MPPTs): Designed with 4 independent MPPT trackers (each input gets its own dedicated tracker).
- Price Impact: Because the
SUN-Sseries uses 2 MPPTs instead of 4, it is roughly 15% to 20% less expensive to manufacture than theSUN-Mquad-MPPT series.

Key Considerations for Your Purchase
- When to Choose
SUN-S(2 MPPTs):- Ideal if all 4 panels attached to the micro-inverter are installed on the same flat roof or face the exact same direction without partial shading from chimneys or trees.
- When to Choose
SUN-M(4 MPPTs):- Better if your panels face different angles or experience selective shading, as each panel will optimize power independently without affecting its paired neighbor.
- 3-Phase Connection Cost (6kW System):
- Buying 3 units of the
SUN-S200G4(2000W) to balance across 3 phases (Phase A, B, C to Neutral) will cost approximately ₹54,000 to ₹60,000 total at distributor rates.
- Buying 3 units of the

Key Takeaway
The SUN-M200G4 (2000W) and SUN-M220G4 (2200W) models offer the best value per watt for 4-panel arrays.
Choose the SUN-M220G4 if you plan to use modern high-wattage panels (600W–790W); choose the SUN-M200G4 if your solar panels are under 700W.
To make the right decision between a Single 3-Phase String Inverter (like the Waaree 4kW) and 3 Single-Phase Micro-inverters (like 3 ×\times× Deye SUN-M200G4 2kW Quad-MPPT) to form a 3-phase system, we need to compare them across cost, performance, installation complexity, and grid compliance.
Here is the comprehensive head-to-head evaluation:
1. System Architecture & Comparison
| Feature / Criteria | 1 × Waaree 4kW 3-Phase String Inverter | 3 × Deye SUN-M200G4 Micro-inverters (1 per Phase) |
|---|---|---|
| Total System MPPTs | 2 MPPTs | 12 MPPTs (4 independent MPPTs per unit × 3 units) |
| Panel Level Tracking / Monitoring | ❌ No (String-level monitoring only) | YES (Module-level monitoring & rapid shutdown) |
| Shading / Partial Obstruction Tolerance | ⚠️ Moderate (Shade on 1 panel drops whole string performance) | EXCELLENT (Shade on 1 panel has zero effect on the remaining 11 panels) |
| DC Cable Wiring on Roof | ⚠️ High Voltage DC run (~250V–400V DC) from roof to inverter | 100% Safe Low Voltage DC (under 60V DC right under each panel) |
| Equipment Cost (Inverter Only) | ~₹40,000 – ₹45,000 | ~₹58,500 – ₹66,000 (3 units × ~₹19,500–₹22,000) |
| Single-Phase Grid Unbalance Handling | ⚠️ Inverter relies on balanced 3-phase grid voltage to stay connected | EXCELLENT (Each phase operates as an independent 230V grid-tied inverter) |
| Warranty & Lifespan | 5 to 8 Years Standard | 10 to 12+ Years Standard |
2. When to Choose 3 Single-Phase Micro-Inverters (Deye SUN-M Series)
Choose 3 ×\times× Micro-inverters if:
- Complex Roof Layout or Partial Shading:
- If your roof has water tanks, stairwell mumbty shadows, trees, or panels facing different angles (e.g., East, South, and West), micro-inverters will generate 15% to 25% more energy annually than a string inverter.
- Phase Balancing Control:
- With 3 single-phase micro-inverters, you connect Unit 1 →\rightarrow→ Phase A + Neutral, Unit 2 →\rightarrow→ Phase B + Neutral, and Unit 3 →\rightarrow→ Phase C + Neutral. This creates a perfectly balanced 3-phase injection while allowing each phase to operate independently. If one phase grid voltage fluctuates, only that micro-inverter throttles while the other two run at 100%.
- Safety & Zero High-Voltage DC:
- High-voltage DC (300V+) from string inverters carries risk of DC arc faults. Micro-inverters keep high DC voltage off your roof; only standard 230V AC runs down the conduits.
- Modularity / Step-by-Step Expansion:
- You can start with 1 unit (4 panels on Phase A) today, and add Phase B and Phase C micro-inverters later as budget permits.
3. When to Choose a Single 3-Phase String Inverter (Waaree 4kW)
Choose the Waaree 3-Phase String Inverter if:
- Clean, Unshaded Roof Space:
- If all your solar panels sit on an open flat rooftop with zero shadows and face the exact same direction (South), a string inverter will match micro-inverter production efficiency (~98%).
- Lower Upfront Budget:
- The Waaree 4kW string inverter costs roughly ₹15,000 to ₹20,000 less in equipment costs compared to buying 3 quad-MPPT micro-inverters.
- Simpler Physical Installation:
- Mounting 1 string inverter box on a wall near your main distribution board is physically faster than mounting 3 micro-inverter units underneath the panel mounting structures on the roof.
4. Summary Recommendation for Your Project
- Go with 3 ×\times× Deye SUN-M Quad-MPPT Micro-inverters if:
- You prioritize maximum energy yield, 10–12 year warranty, panel-level monitoring, and complete protection against shading from nearby rooftop structures.
- Go with the Waaree 4kW 3-Phase String Inverter if:
- Your roof has zero shading, all panels face one direction, and your priority is keeping initial hardware costs as low as possible.
