Electric fence energizer backup (rural NZ overnight Wh)
Keep a mains energizer ticking through a line fault or storm night — labelled Wh math, surge notes, and when a mid-size station is thin for big multi-joule units. Not farm advice: follow the energizer maker and local fencing rules.
When a station is thin
- Many small/medium energizers sip watts. Compact mains units often average well under 50 W — overnight is easy on ~300 Wh if the label agrees.
- Large joule / long-fence units can draw more continuous power and hate dirty earths (higher effective load). Measure wall watts under your fence condition.
- Surge is usually mild vs well pumps — but cheap modified-sine bricks and some switch-mode PSUs still prefer pure sine.
- 12 V / battery energizers may already have a farm battery — don’t double-convert through AC unless that’s the designed path.
- Solar energizers are often the better permanent rural answer; a portable station is a storm bridge, not a paddock architecture.

Overnight Wh estimates
Hours ≈ (rated Wh × 0.85) ÷ energizer average watts.
Compact energizer ~15 W
Mid unit ~40 W
Hungry / long fence ~100 W+
Comparison: energizer backup stations
Filter by fence load. Prefer pure sine; keep the station dry and elevated.
| Model | Wh · AC | Est. @ 15–40 W | Fence honesty | Approx. USD |
|---|---|---|---|---|
| EcoFlow RIVER 3 Plus Shed shelf | 286 Wh · 600 W | ~6–16 h (est.) | Strip / lifestyle block overnight if draw is low; thin for big mains energizers. | ~$180–300 |
| Anker SOLIX C300 | 288 Wh · 300 W | ~6–16 h class (est.) | Check continuous W vs energizer brick. | ~$200–280 |
| Jackery Explorer 1000 v2 Quiet night | 1,070 Wh · 1,500 W | ~21–58 h class (est.) | Comfortable mid-energizer overnight for many NZ lifestyle farms. | ~$499–589 |
| BLUETTI Elite 100 V2 | 1,024 Wh · 1,800 W | ~21–58 h class (est.) | Pure sine class; UPS helps if the brick hates flickers. | ~$380–500 |
| Anker SOLIX C1000 Expand | 1,056 Wh → 2,112 Wh | ~21–58 h · ~2× expanded | Add pack when storms stack with stock water loads. | ~$400–600 |
| EcoFlow DELTA 3 Plus | 1,024 Wh · 1,800 W · solar path | Overnight mid; expand / solar for multi-day | Still thin vs huge commercial energizers without extras — measure first. | ~$600–900+ |
| BLUETTI AC200L Buffer | 2,048 Wh · 2,400 W | ~43–115 h @ 15–40 W (est.) | Best Wh in this set for hungry units; dedicated 12 V farm battery may still be cleaner. | ~$800–1,100 |
