String inverters
A central or string inverter serves groups of panels. It is common, efficient and relatively straightforward when array conditions suit it.

HEY SOLAR KNOWLEDGE HUBWhat does a solar inverter do?
A solar inverter converts the direct-current electricity produced by PV panels into alternating-current electricity that your home or business can use. It is also central to system monitoring, protection and grid interaction.
THE SHORT ANSWER
A solar inverter converts the direct-current electricity produced by PV panels into alternating-current electricity that your home or business can use. It is also central to system monitoring, protection and grid interaction.
Microinverters and optimisers
Panel-level electronics can offer granular monitoring or help certain complex/shaded layouts, but they add hardware and should solve a real design need.
Hybrid inverters
A hybrid inverter can integrate solar and battery functions in one architecture. Compatibility, power limits and future expansion should be checked.
Do not compare on headline efficiency alone
Warranty, support, monitoring, power limits, MPPT design, battery compatibility and installer familiarity can matter alongside conversion efficiency.
HOW WE HANDLE THE DETAIL
HEY Solar keeps technical and financial claims tied to the assumptions that make them true. Guidance is reviewed against authoritative UK sources and property-specific decisions belong in a survey and design.
