15kVA Silent Diesel Generator — Weichai Powered (AG-15S)

Extremely capable and properly quiet, the AG-14S is the unit we recommend most for home backup. It powers a 4-bed home — heating, pumps, fridge-freezers, lights, Wi-Fi — without you having to think about what's switched on. Runs for about £1.10 per hour at 75% load (roughly £26 for a full day).

If you're running three-phase equipment — workshops, milking machines, big compressors — this isn't your unit. Look at the AG-45T instead.
