Compact connected diesel DC generator for 48V battery backup charging.
D100 AutoGen is a compact connected DC generator package built around the single-cylinder Kohler KD15-440 diesel engine, variable-RPM generator, permanent magnet alternator, adjustable charging current up to 100 A, and adjustable charging voltage up to 57.6 V. AutoGen control adds automatic starting, app and dashboard access, local access, API support, and dealer fleet tools.
Compact diesel charging with connected AutoGen control.
D100 combines adjustable 48V charging with automatic generator control, connected monitoring, and a compact single-cylinder diesel package.
Adjustable DC charging
D100 provides charging output up to 5.6 kW, with current adjustable up to 100 A and voltage adjustable up to 57.6 V.
Automatic charging control
AutoGen manages configured start conditions, engine starting, run confirmation, charging state, stopping, runtime history, and supported alerts.
Remote and local visibility
Use the app and web dashboard through WiFi or LTE, with BLE setup and WiFi Local AP access available nearby.
Compact diesel package
The single-cylinder Kohler KD15-440 keeps D100 among the smallest diesel generator packages in the AutoGen range.

Is D100 the right size for the installation?
Choose D100 when the site needs diesel fuel, charging output up to 5.6 kW and 100 A, and a smaller package than D180.
Best fit
Off-grid battery banks, hybrid backup systems, technical sites, remote infrastructure, and installations that prefer compact diesel charging.
Use V100 instead
Choose V100 when petrol is preferred or the lighter 51 kg Honda GX390 generator package is better suited to the installation.
Use D180 instead
Choose D180 when the installation needs charging current above 100 A or output up to 10 kW.
Measured performance, manual, and API documentation
At the 100 A test point, D100 delivered 5.50 kW at 55.00 V, with measured fuel consumption of 1.50 L/h and 36.9% fuel-to-electric efficiency.
D100 product questions.
Key points about charging output, connectivity, direct DC charging, and choosing D100 within the AutoGen range.
Does D100 charge a 48V battery bank directly?
Yes. The permanent magnet alternator provides adjustable DC charging output up to 100 A and 57.6 V, without using a conventional AC-first generator and external battery-charger path.
Does D100 include connected monitoring?
Yes. Depending on configuration, D100 can use WiFi or LTE for cloud access, with app and dashboard visibility, BLE setup, WiFi Local AP, API support, and dealer tools. GPS is available with the LTE version.
When should I choose D100 instead of V100?
Choose D100 when diesel fuel is preferred. Both models provide charging up to 5.6 kW and 100 A, while V100 uses the Honda GX390 petrol engine in a lighter package.
Who is D100 for?
D100 suits off-grid battery banks, hybrid backup systems, technical sites, remote infrastructure, and installations that need compact connected diesel charging.
