Enphase IQ8H Microinverter — Ireland 2026
25-year warranty per panel — solar backup without a battery, IP67 rated
The Enphase IQ8H is a per-panel microinverter — instead of one central inverter, every solar panel gets its own dedicated converter mounted on its rear. The result is maximum resilience: if one unit fails, only that panel is affected. The IQ8H's Sunlight Backup feature provides emergency power from solar panels alone during grid outages — no battery required. At 25 years, the warranty is the longest of any inverter product in this directory. IP67 fully waterproof rating. The Enphase Enlighten app provides per-panel generation monitoring that no central inverter can match.

✅ What we like
- 25-year warranty — the longest of any inverter product in this directory
- IP67 fully waterproof — highest weather protection rating available
- Sunlight Backup — emergency solar power during grid outages without a battery
- Per-panel independence — one failure only affects one panel, not the whole system
- Enphase Enlighten — best-in-class per-panel monitoring app
- No high-voltage DC on the roof — safer installation and maintenance
⚠️ Worth knowing
- Highest cost per kWp — 10 microinverters (~€1,800) + IQ Gateway (~€200) vs ~€1,100–1,250 for a central hybrid
- More components on the roof — more points of potential failure (mitigated by 25-yr warranty)
- Battery compatibility limited to Enphase IQ Battery only
- Specialist Enphase-certified installer required
📐 System sizes — full installed cost & SEAI grant
⚠️ Microinverter pricing: one IQ8H (~€180) is needed per panel. A 10-panel (4kWp) system requires 10 microinverters (~€1,800) plus the Enphase IQ Gateway (~€200). The system cost above includes all microinverters.
Full system costs include panels (avg 430W), this inverter (~€180), mounting and labour. SEAI Solar PV Home Grant of up to €1,800 applies to all components. Battery column adds a ~10kWh LFP battery (~€3,200 avg) — the grant does not cover batteries.
| System | Panels | Est. generation | Solar only (after grant) | + Battery 🔋 | Est. payback |
|---|---|---|---|---|---|
| 3 kWp | 7 panels | ~2,700 kWh/yr | ~€3,080 | ~€6,280 | ~8 yrs |
| 4 kWp | 10 panels | ~3,600 kWh/yr | ~€3,980 | ~€7,180 | ~8 yrs |
| 5 kWp | 12 panels | ~4,500 kWh/yr | ~€4,880 | ~€8,080 | ~8 yrs |
| 6 kWp | 14 panels | ~5,400 kWh/yr | ~€5,780 | ~€8,980 | ~8 yrs |
| 8 kWp | 19 panels | ~7,200 kWh/yr | ~€7,580 | ~€10,780 | ~8 yrs |
