Thirty kilowatts of continuous On-Grid capacity materially shifts monthly demand charges for warehouses and production halls—especially when load aligns with solar peak. The G04 platform stays in the On-Grid domain: no SOC management, no DC arc-flash protocols beyond PV open-circuit voltage.

Designers should coordinate AC breaker frames, surge protection, and labeling with the facility's main LV panel. Multiple MPPT trackers accommodate long combiner runs from distant roof sections. If export is capped below instantaneous production, configure gradient export limits to avoid utility disconnects.

Crossing into storage territory (>40 kWh or backup mandates) typically pivots to HV hybrid (SG01HP3) rather than bolting LV racks onto an On-Grid-only site. Treat this inverter as the generation engine; add storage as a deliberate second CAPEX line.

Ideal for

  • ✓ Medium warehouses and agro-processing with 30 kW connection tiers
  • ✓ EPC firms standardizing on Deye commercial On-Grid SKUs
  • ✓ Owners separating generation ROI from future storage phases

Technical FAQ

When does 30K On-Grid hit diminishing returns vs hybrid?
When outage cost exceeds storage CAPEX—hospitality, medical, cold chain—or when peak demand charges exceed 0.35 ₾/kWh energy savings alone.
Can I add batteries to this model?
Not natively. Plan a hybrid feeder or AC-coupled storage inverter for critical circuits.
Typical payback drivers?
Self-consumption rate, module $/W, installation quality, and tariff escalation—not nameplate kW alone.
EV fleet charging?
Daytime PV can feed 22 kW wallboxes; coordinate breaker sizing and dynamic load management with our charger lineup.
