Most solar installations ship with no meaningful fault protection at all. PV protectors guard against arc faults, voltage surges, and isolation failures — the events that cause equipment damage, downtime, and, in the worst cases, fire. They retrofit to any system in a single visit.
It's an uncomfortable statistic: roughly 73% of UK solar systems have no arc-fault protection fitted. DC arc faults are a known cause of solar fires, surges from lightning or grid switching can take out an inverter in an instant, and isolation faults quietly escalate until something gives.
PV protectors address all three. Arc-fault detection spots and interrupts dangerous arcing in DC circuits. Surge protection absorbs spikes before they reach your inverter. Isolation monitoring catches ground faults early, while they're still cheap to fix.
The maths is straightforward: protection costs a fraction of a replacement inverter, let alone the disruption of a fault. It's compatible with every inverter brand and fits without taking your system offline.
Identifies and interrupts dangerous DC arcing — a leading cause of solar-related fires.
Absorbs voltage spikes from lightning and grid switching before they reach the inverter.
Catches ground and isolation faults early, before they escalate into damage.
Works with any inverter make and model — no need to change existing equipment.
Fitted in a single visit without taking your system offline.
A small, one-off cost against the real risk of damage, downtime, and worse.
A short, single-visit job that closes the most serious gap in most installations.
Most owners assume their installer fitted protection. Often they didn't. A quick check settles it — and it's a small cost to put right.
