20kVA Isuzu Diesel Generator | For House Power Backup
Product Description
This Isuzu generator is housed inside a high-quality, powder-coated soundproof enclosure operating at quiet residential noise levels (65–68 dBA @ 7m). This silent Isuzu diesel generator integrates an automatic voltage-regulated alternator, Deepsea digital controller, and Delixi circuit breaker—delivering seamless emergency restoration for modern residential and light commercial loads.
1. High-Efficiency Engine Architecture (Isuzu Tech)
-
The precision-tuned Isuzu generator engine maximizes fuel atomization, offering remarkably low hourly fuel consumption during extended utility blackouts.
-
Set-mounted water-cooling system with fan guards engineered to maintain optimal engine temperatures up to 40°C ambient heat.
-
Integrated engine protection sensors immediately trigger auto-shutdown during low oil pressure, high water temperature, or over-speed conditions.
2. Power Precision & Voltage Regulation
-
3-phase 4-wire (230/400V) or single-phase configurations delivering stable, low-harmonic output for home electronics.
-
Automatic Voltage Regulation (AVR) stabilizes output voltage within ±1%, safeguarding sensitive household HVAC units and appliances.
-
Features Class H thermal winding insulation and IP23 water-spray resistant housing for continuous duty.
