Solis (Ginlong) RHI-3P5K-48ES 5kW — Ireland 2026
Best-value hybrid in Ireland — multi-battery compatible at a lower price
The Solis RHI-3P5K-48ES is the go-to budget hybrid inverter for Irish solar installers. At ~€950 it saves €300 vs the Huawei SUN2000-5KTL-L1 while still delivering hybrid capability, battery backup, SolisCloud monitoring and a 10-year warranty. The key differentiator: Solis is compatible with Pylontech, BYD, Alpha ESS and Solax Triple Power batteries — giving homeowners freedom to choose the battery that best suits their budget and needs, rather than being locked into a single ecosystem.

✅ What we like
- Multi-battery compatible — Pylontech, BYD, Alpha ESS, Solax (choose your battery independently)
- ~€300 less than Huawei SUN2000-5KTL-L1 for the same output
- 10-year warranty at a lower price point
- Backup power capability — keeps essential circuits live during grid outages
- Irish distributor in Co. Carlow — strong domestic parts and support network
- SolisCloud monitoring with live generation and battery data
⚠️ Worth knowing
- SolisCloud app is functional but less polished than Huawei FusionSolar or Fronius Solar.web
- Solis brand recognition is lower than Huawei or Fronius — may be harder to explain to future home buyers
- Efficiency (97.5%) marginally below Huawei (97.8%) — negligible in practice
