Compact connected diesel DC generator for 48V battery backup charging.
D100 AutoGen is a compact connected DC generator package built around a single-cylinder Kohler KD15-440 diesel engine, variable rpm generator, permanent magnet alternator, adjustable charging current up to 100 A, adjustable charging voltage up to 57.6V, AutoGen control, app access, cloud monitoring, local access, API support, and dealer fleet tools.
Choose D100 for compact diesel 48V DC backup charging.
D100 is the smaller diesel AutoGen package for 48V battery banks, off-grid sites, hybrid backup systems, and remote infrastructure that need reliable DC charging with connected monitoring and support.
Direct 48V DC charging
D100 is built around a direct 48V DC charging path with AutoGen control, rather than a generic AC-first generator workflow.
Selectable 100A DC charging
D100 supports selectable charging current up to 100A and selectable charging voltage up to 57.6V for 48V battery banks.
Connected support path
Cloud dashboards, mobile app access, BLE terminal workflows, WiFi Local AP access, API paths, and dealer fleet tools remain part of the generator package.
One of the smallest diesel packages in the range
The single-cylinder Kohler KD15-440 helps keep D100 compact while still giving the product range a connected diesel 48V DC charging option.

The AutoGen platform, applied to a compact diesel DC generator.
D100 uses the same connected AutoGen direction as the wider generator range: live telemetry, schedules, settings, device management, firmware workflows, API access, and dealer support.
Telemetry dashboard
Live state, voltage, runtime, and operating data help owners and dealers monitor charging behavior clearly.
App device access
Owners, installers, and support teams can identify and access the correct AutoGen device quickly.
Schedules and settings
Supported settings can cover charging profiles, scheduled runtimes, start and stop behavior, and installed hardware options.
Dealer fleet support
D100 fits managed deployments where dealer visibility and fleet workflows are part of normal support.
Diagnostic events
Event history helps confirm starts, stops, run confirmation, faults, resets, communication state, firmware actions, and controller behavior during field support.
Choose D100 when the site needs the compact AutoGen diesel package.
Use D100 when the site needs diesel 48V DC charging in a smaller connected package than D180.
Best fit
Off-grid systems, hybrid backup solutions, technical installations, remote infrastructure, and backup sites that need a compact connected diesel DC generator package.
Use V100 instead
Choose V100 when the installation is smaller, lighter, or better suited to the petrol generator path with the same charging requirement.
Use D180 instead
Choose D180 when the battery bank, site load, or runtime expectation calls for the larger 10 kW AutoGen diesel DC generator package.

D100 questions that help with product selection.
These answers focus on where D100 fits in the AutoGen DC generator range, how it compares with V100 and D180, and why the compact diesel package is the right fit for certain deployments.
Is D100 still a direct 48V DC charging path?
Yes. D100 is a direct 48V DC battery-charging generator package with a variable rpm generator, adjustable voltage and current output, permanent magnet alternator, and AutoGen control, rather than a generic AC-first generator workflow.
Can D100 use WiFi or LTE for remote support?
Yes. D100 follows the connected AutoGen path with WiFi or LTE cloud access, BLE terminal workflows, and local access options for setup and support.
When should I choose D100 over V100?
Choose D100 when the site needs a compact diesel charging package with up to 5.6 kW output, 100A selectable charging, and connected support.
Does D100 still fit dealer fleet workflows?
Yes. Dealer visibility, runtime tracking, platform telemetry, API paths, and remote support workflows remain part of the D100 direction.
