Deye B2B

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-S series uses 2 MPPTs instead of 4, it is roughly 15% to 20% less expensive to manufacture than the SUN-M quad-MPPT series.

Key Considerations for Your Purchase

  1. 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.
  2. 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. 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.

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

❌

2. When to Choose 3 Single-Phase Micro-Inverters (Deye SUN-M Series)

Choose 3 ×\times× Micro-inverters if:

  1. 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.
  2. 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%.
  3. 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.
  4. 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:

  1. 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%).
  2. 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.
  3. 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.
