Hydroponics Energy & Backup — NFT, DWC & Drip-to-Slab Loads, Generators, Battery & RFQ
In hydroponics an outage is not an inconvenience — DWC roots suffocate in minutes if the aerators stop. Battery-bridged UPS on aerators, dosing and lights is not optional; it is the specification.
How are these load assumptions derived?
Figures are reference values from typical commercial projects — real numbers depend on climate, crop, motor selection (DOL vs VFD), controls topology and outage-risk tolerance. Use them to frame the RFQ; final sizing is confirmed by the winning EPC and OEM as part of the engineered proposal.
Reference figures. Real specs and pricing come from the qualified suppliers that respond to your private RFQ. SeedMatchGroup does not resell equipment.
Core loads: recirculation and aeration pumps, chillers, fertigation dosing (A + B + acid), grow-room HVAC, dehumidification, LED lighting (large share), CO₂ enrichment and controls.
Critical loads dominate: aeration, dosing and root-zone temperature. Lighting can be shed on outage; oxygen cannot.
Typical load assumptions
Continuous vs peak vs critical (must-survive-an-outage) loads by project scale. Motor starting inrush is 4–7× nameplate for direct-on-line and ~1.5–2× on VFDs — genset kVA must cover the worst-case inrush without voltage collapse.
| Project scale | Continuous | Peak / inrush | Critical load | Runtime target |
|---|---|---|---|---|
| 500 m² indoor (NFT / DWC) | 15–30 kW | 35–60 kW | 5–8 kW | 12–24 h |
| 2000 m² CEA farm | 70–140 kW | 180–280 kW | 20–35 kW | 12–24 h |
| 5000 m² CEA + LEDs | 220–380 kW | 500–800 kW | 50–80 kW | 24 h+ |
| 1 ha greenhouse hydro | 80–160 kW | 200–350 kW | 25–45 kW | 12–24 h |
Recommended generator & storage setups
Vendor-neutral reference stacks — diesel or gas generator, LFP battery storage, optional solar PV, ATS and controls. Hybrid stacks let solar and battery serve daytime load while the genset only starts on demand.
| Scale | Generator | Battery (LFP) | Solar PV | ATS / controls | Notes |
|---|---|---|---|---|---|
| 500 m² | 40–60 kVA diesel | 20–40 kWh LFP | Optional 10–30 kWp | ATS + UPS 3–5 kVA on aerators & controls | UPS on aeration is non-negotiable. |
| 2000 m² | 200–275 kVA prime | 80–150 kWh LFP | 60–120 kWp | ATS + UPS 10 kVA + EMS | Battery covers dosing + aeration through genset start. |
| 5000 m² | 500–650 kVA prime | 250–450 kWh LFP | 200–400 kWp | Paralleling gear + EMS + SCADA | LED dimming under EMS caps peak demand. |
| 1 ha greenhouse hydro | 250–350 kVA prime | 120–200 kWh LFP | 100–200 kWp | ATS + UPS 10 kVA + EMS | Solar-first with fertigation shifted to solar noon. |
- UPS on aerators, dosing pumps and controls — batteries carry the 8–15 s ATS transfer.
- Redundant aeration (N+1) on DWC systems — cheapest crop-insurance you can buy.
- LFP battery sized on critical runtime, then cross-checked against LED demand shaving.
- EMS to shift fertigation and LED dimming to solar noon.
- Environmental alarms tied into UPS-backed controls and SMS/WhatsApp escalation.
