PV550 in Village Central Water Supply: Designing Solar Pump + Constant-Pressure Systems
日期：2026-10-02 浏览次数：10
The following is a typical PV550 system-design scenario for 'village water supply'. Parameters are common-config examples, not a named customer delivery contract.
1. Background
A village with a weak grid and occasional night outages relied on costly diesel water extraction with unstable pressure. Multiple draw points (public taps, storage tank, school) peaked at the same hours, needing a 'PV-primary, grid-backup' central constant-pressure supply.
2. System composition
| Stage | Typical config |
|---|---|
| Source | Deep well / river → three-phase pump (sized to head and total flow) |
| Inverter | HBDTECH PV550 solar pump inverter: MPPT + automatic PV/grid switching + dry-run protection |
| Pressure | CPC-6 constant-pressure controller (or built-in PID), multi-pump control holds network pressure |
| Storage | Elevated tank + pressure vessel for peak shaving and continuous supply |
| Power | PV array + grid complement; auto-switch supplements when grid is available |
3. Operation
In daylight, PV550 uses MPPT at max power to fill the elevated tank; at peak demand the constant-pressure controller holds network pressure so all draw points stay stable. When grid is available or light is low at night, automatic PV/grid switching backs up supply, and dry-run protection prevents empty-well running.
4. Value
Versus diesel extraction, solar + constant-pressure removes ongoing fuel cost and pressure swings — lower long-term cost and higher reliability, ideal for sunny, grid-weak villages.
