SolarEdge Home Hub 5kW + P401 Optimisers — Ireland 2026
Per-panel DC optimisation — ideal for shaded or multi-orientation Irish roofs
SolarEdge Home Hub with P401 DC power optimisers is the solution for Irish roofs that are not ideal. Most Irish homes have chimneys, dormer windows, satellite dishes, or part-shading from trees — and in a conventional string inverter, the weakest panel drags down the entire string. SolarEdge places a power optimiser on the back of every panel, allowing each to operate independently at its maximum power point. The result: 99.2% efficiency (the highest of any inverter in this directory), per-panel generation monitoring, and a 25-year optimiser warranty. The 12-year inverter warranty is also above the residential standard.

✅ What we like
- 99.2% efficiency — highest of any inverter in this directory
- Per-panel monitoring — identify shading, faults and underperformers panel by panel
- DC optimisers eliminate string drag — each panel operates at its own maximum power point
- 12-year inverter warranty — above the 10-year residential standard
- 25-year power optimiser warranty — outlasts the panels themselves
- Compatible with SolarEdge Home Battery and LG Chem RESU for storage
- Backup power capability
⚠️ Worth knowing
- Most expensive optimiser-based residential system — Home Hub ~€1,800 + ~€50–70 per optimiser × panel count
- P401 optimisers add ~€500–700 to the cost of a 10-panel system vs a standard inverter
- If the central inverter fails, the whole system stops (unlike microinverters where one failure is isolated)
- Battery compatibility limited to SolarEdge Home Battery and LG Chem RESU
- Specialist installation required — not all Irish installers are SolarEdge certified
📐 System sizes — full installed cost & SEAI grant
ℹ️ Optimiser pricing: P401 power optimisers (~€50–70 each) are priced separately per panel. For a 10-panel system, add ~€500–700 to the inverter price above. The system estimates below include inverter + optimisers + panels + installation.
Full system costs include panels (avg 430W), this inverter (~€1,800), 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 | ~€4,700 | ~€7,900 | ~12 yrs |
| 4 kWp | 10 panels | ~3,600 kWh/yr | ~€5,600 | ~€8,800 | ~11 yrs |
| 5 kWp | 12 panels | ~4,500 kWh/yr | ~€6,500 | ~€9,700 | ~10 yrs |
| 6 kWp | 14 panels | ~5,400 kWh/yr | ~€7,400 | ~€10,600 | ~10 yrs |
| 8 kWp | 19 panels | ~7,200 kWh/yr | ~€9,200 | ~€12,400 | ~9 yrs |
| 10 kWp | 24 panels | ~9,000 kWh/yr | ~€11,000 | ~€14,200 | ~9 yrs |
