01 / Why we're here
Supported in the UK
UK roofs are complicated. Our job is to make them simple, safe and fully productive — without asking installers to change the kit they trust.
Why we're here
UK roofs are rarely simple. Shade, mixed pitches and complex layouts cost generation, and high DC voltage on the roof is a real risk. Installers want panel-level control and visibility without changing the inverters they trust — and they want someone in the UK to pick up the phone.
What we do about it
Archai pairs panel-level optimisers, a wired data gateway and the SolarSync platform into one system. It's certified with the UK's leading inverter brands, and sold and supported by our team here in the UK.

02 / What makes us different
Six reasons installers choose Archai.
Practical engineering for real UK jobs — and a team that answers the phone.
01
Built for UK roofs
Chimneys, dormers, split pitches and shade. Panel-level MPPT keeps every module working at its own best.
02
Keep your inverter
Certified with Solis and Fox ESS — the UK's leading inverter brands. No need to switch kit to add optimisation.
03
Wired, not wireless
PLC sends data down the DC cable. No router placement, no Wi-Fi dropouts, fewer callbacks.
04
Safety at every panel
Rapid shutdown takes each optimiser to a 1 V safe output. Genuine Stäubli MC4 removes cross-mating risk.
05
UK support, start to finish
Design help, commissioning support and warranty claims — all handled by our team here in the UK.
06
Funding-ready
Approved under Ofgem's ECO4 Innovation Measure (IM045). Backed by a 25-year replacement warranty.
03 / The system
Three parts. One install.
Optimiser on each panel. Gateway in series between the string and the inverter. Everything visible in SolarSync.
04 / Who we work with
Built for the trade.
We sell through installers and distributors, and work with inverter manufacturers on compatibility.

07 / Why optimise
With vs without.
On a standard string, one shaded panel drags down the rest. Optimisers stop that. Try it.
Demo / 002 · Shade a panelClick panels
Click a panel to cycle shade: 0% → 50% → 80%. Simplified concept model: 8 × 450 W on one MPPT, bypass diodes approximated. Not a yield estimate.
| With Archai | String only | |
|---|---|---|
| Safety | Panel-level shutdown to 0 W | High DC voltage across the array |
| Shading | Each panel runs at its own MPP | One shaded panel lowers the string |
| Visibility | Per-panel data and alerts | No panel-level view |
| Maintenance | Find the faulty panel remotely | Manual testing on site |
| Over time | Balances panel ageing | Losses build up |
