How should I timer a pool pump for solar self-use in South Africa?

Run filtration through the PV peak where water quality allows, and keep the pump off the essential board unless you truly need Stage filtration — timers plus monitoring beat running 24/7 on a small hybrid.

Answer first: Put the pool pump on a timer aligned to your PV curve and off the essential board unless chemistry truly needs Stage runtime — pool pump · pool heat pump · chlorinator · export vs self-use.

Timer patterns

Season	Typical approach
Highveld summer	Longer midday window; watch storms
Cape winter	Shorter window; may need grid top-up
Stage clusters	Accept skipped hours; do not sink the battery

Measure first — then size — then buy

Clamp the evening essentials, log a week of bill data, and only then accept a bill of materials. Quotes written from a sales average miss your house. Bring the measurement sheet to every installer meeting.

When the quote ignores your numbers, discard it.

Pool timer aligned to PV surplus

Shift filtration into the high-PV window and you convert export/clipping into clean water. Smart relays driven by the inverter beat fixed mechanical timers when clouds move. Re-check water quality if you cut winter hours aggressively.

Quick questions

On essentials?

Usually no — filtration can wait out Stage if chemistry allows.

Best hours?

Late morning to mid-afternoon on sunny days; adjust seasonally.

Heat pump too?

Sequence heat pump after filtration; watch inverter headroom.

Variable-speed pumps?

Lower kW helps hybrids — still timer the window.
