Business & Commercial Applications

This 40kVA unit is the perfect commercial generator for mid-sized businesses, office parks, agriculture, and retail outlets. It provides dependable backup power to keep your critical systems, point-of-sale terminals, and security running smoothly during load shedding.

Solar & Inverter Backup Compatible

This generator model is equipped to produce stable, clean AC power (featuring an Automatic Voltage Regulator), making it highly suitable for integration with hybrid solar inverters (such as Sunsynk, Deye, or Victron) to charge batteries during extended outages.

Compatibility & Sizing Note: You must verify compatibility with your specific inverter's AC-input requirements. Furthermore, generator sizing cannot be 1:1 with your inverter. The generator must be sized to handle your property's maximum base load plus the inverter's maximum battery charge rate to prevent overloading.

IMPORTANT: This product must be installed by a qualified electrician. A Certificate of Compliance (COC) must be issued on completion.
NOTE: The generator cannot take full load instantaneously. Load should be added gradually (50% initially) once the engine is up to temperature. E&OE — all figures are approximate.

Frequently Asked Questions

No. Installations vary significantly and require different lengths of cable and travel. Installations must be done by a qualified electrician to issue a valid Certificate of Compliance (COC) for your insurance. We can recommend a qualified local installer.

All prices exclude delivery. Due to the size and weight, delivery requires a specialised truck and rigging crew. Therefore, delivery is charged separately based on distance and complexity.

Yes. You need either an Automatic Transfer Switch (ATS) or a Manual Changeover Switch to link the generator safely into your property's distribution board and isolate it from the municipal supply. If you're connecting it directly to your inverter to charge batteries, you do not need an ATS or manual switch, but you do require a 2-Wire start if the generator is to start and stop automatically (if your inverter is capable of this).

Prime power (PRP) is the continuous rating for unlimited hours with a variable load — this BPD40S3-C is rated 40 kVA prime. Standby power (LTP) is the higher short-duration emergency rating — 44 kVA standby on this model. For load-shedding backup, size to the standby rating; for continuous/off-grid use, size to the prime rating.

The BPD40S3-C is a silent (sound-attenuated) diesel generator rated at approximately 72 dBA at 7 metres. The canopy is designed to reduce noise while maintaining airflow; enclosing it further can cause overheating.

The BPD40S3-C has a 100 litre tank and consumes about 6.6 l/h at 75% load, giving roughly 15 hours runtime at 75% load. Actual runtime varies with load, ambient temperature, and fuel quality. E&OE — figures are approximate.

Yes. The BPD40S3-C produces stable AVR-regulated AC power suitable for hybrid solar inverters (such as Sunsynk, Deye, or Victron) to charge batteries during extended outages. Size the generator for your base load plus the inverter's maximum battery charge rate — not 1:1 with inverter kW.

No. The generator is mounted on anti-vibration mountings, so anchoring is not required for operation. You may still secure it for theft prevention.

Silent generators are designed to minimise sound while optimising airflow. Any restriction of airflow will cause overheating and engine damage. We strictly advise against after-market silencing solutions.

The warranty is 12 Months or 1000 Hours, whichever occurs first. This is a limited carry-in warranty (travel to site is not included). The unit must be returned to the branch of purchase for assessment.
