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.
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.

FAQ
- 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.
- Do these setups include ATS, UPS and controls?
- Yes. Every recommendation assumes an Automatic Transfer Switch on the incoming feed, a UPS on the climate computer / control cabinet, and a supervisory controller (EMS) if a hybrid stack is specified. This is a single, integrated procurement package — not three separate purchases.
- Does SeedMatchGroup sell generators or batteries?
- No. SeedMatchGroup is a human-led global sourcing platform supported by proprietary technology. The full energy stack — generator, battery, inverter, ATS, UPS, EMS — is specified inside your RFQ and opened privately to qualified global suppliers and integrators.
