Why GivEnergy is #1 for most UK homes:

• Built-in smart tariff modes — Octopus Flux, Go, and Agile automation is firmware-level, not app-based. Set your tariff once and the inverter handles all charge/discharge scheduling.
• Native battery integration — designed from the ground up for GivEnergy batteries. No compatibility issues.
• UK company — Newcastle HQ, UK-focused development, responsive UK support.
• Competitive pricing — £1,000–£1,800 for a 3.6–8kW hybrid inverter.
• Excellent cloud portal and app — real-time monitoring, remote control, historical data.
• Wide installer availability — most UK MCS installers stock GivEnergy.

Models: - GivEnergy 3.6kW Hybrid — suits 3–4kW systems - GivEnergy 5kW Hybrid — suits 4–5kW systems - GivEnergy 6kW Hybrid — suits 5–6kW systems - GivEnergy 8kW Hybrid — suits 6–8kW systems

Choose GivEnergy if: You want battery compatibility, smart tariff automation, and the best value hybrid inverter.

Why SolarEdge for shaded roofs:

• Panel-level optimisers included with every SolarEdge system — each panel has its own MPPT
• Shading recovery — if one panel is shaded, only that panel's output drops. Others maintain full output.
• 12-year warranty as standard (extendable to 25 years) — longest standard inverter warranty
• SafeDC — reduces panel voltage to safe levels when system shuts down (firefighter safety)
• Panel-level monitoring — see exact output from each panel in the app

Choose SolarEdge if: Your roof has partial shading from chimneys, trees, or neighbouring buildings, and you want panel-level insight.

Why Enphase for complex roofs:

• True panel independence — each panel has its own complete DC-to-AC inverter
• 25-year warranty — matches the panel lifespan (no inverter replacement at year 12)
• No high-voltage DC on roof — each panel converts at low voltage (safest system)
• Best for mixed orientations — panels facing different directions operate independently
• Easy expansion — add one panel at a time, no string matching required

Choose Enphase if: You have significant shading, panels on multiple roof slopes, or want the longest inverter warranty and maximum safety.

Downside: Most expensive option. Battery integration is AC-coupled (slightly less efficient than DC-coupled GivEnergy).

Why Solis for budget-conscious:

• Lowest cost — £400–£800 for a 3.6–6kW inverter
• Reliable — Solis is the world's 4th largest inverter manufacturer (scale = proven)
• Good for simple installations — unshaded, single-direction roofs
• Hybrid models available — Solis hybrid inverters support batteries
• 5-year warranty (extendable to 10)

Choose Solis if: Budget is your primary concern, your roof is unshaded, and you want a proven, affordable inverter.

Downside: Smart tariff integration is basic. App is functional but less polished than GivEnergy. UK support infrastructure is smaller.
