The configuration is calculated according to load profile, runtime, charging window and operating environment.
In industrial applications, inrush current, overload duration, protection concept, temperature range, charging power and service concept determine real-world usability.
Engineering
Developed by a PhD engineer with many years of experience in power electronics (including a technical lead role at Delta). With a breakthrough in inverter technology, the system is lighter and more powerful than conventional solutions – purpose-built for harsh environments and protected by patents. The GM 3600 reliably withstands heat, cold, dust, moisture and vibration, and can be used effortlessly on construction sites, in service vehicles and on mobile jobs.

Field & lab test
Not just a datasheet: here the GM 3600 works visibly under real load – in the lab on the 20 kW RLC test bench at twice rated power, and in the field with a professional cut-off saw.
Oscilloscope measurement of the load peak: 229 A at 228 V (RMS) = 18,462 W – held for ~1 s (5 × 200 ms within the measurement window). That corresponds to about 500 % of rated power – so the GM 3600 safely starts high-inrush motors, compressors and cut-off saws. Measured with a Keysight DSO-X 3054T.
Tested performance
Traceable measured values: capacity, charge/discharge power, overload up to 500 % and a field test with professional tools.
Why GM 3600 instead of a generator?
Forget pulling the starter cord and maintaining petrol/diesel generators. The GM 3600 delivers a genuine 3,600 W of continuous power – clean, quiet and at the push of a button. Whether a heavy diamond cut-off grinder, a welder or sensitive measuring equipment: you bring the socket straight to the point of use.
100 % safe for use in enclosed spaces, cellars and tunnels – no trip hazard cable.
No fuel costs, no oil changes – return on investment in record time.
Compact, rugged, ready to use instantly. Fast charging over lunch – keep working in the afternoon.
Reliably powers: diamond cut-off grinders, rotary hammers, table & mitre saws up to ~2,500 W, industrial compressors, welders, work lights as well as sensitive measuring & test equipment. 18 kW peak power absorbs inrush currents without a voltage dip.
*Assumption: average load 1,500 W. A 2 kW generator consumes about 1.2 L/h. Maintenance costs (oil, filters) are not included – so the real savings are even higher.

–Comparison & alternatives
Anyone who needs off-grid 230 volts on the construction site, in landscaping or in a service vehicle often compares the GM 3600 with portable professional power stations (e.g. Instagrid) as well as with the battery platforms from Hilti and Stihl. The difference: our mobile energy storage delivers a genuine 230 V / 3.6 kW of continuous power (18 kW peak) – emission-free, quiet and IP54 – and thereby charges or runs tools, chargers, pumps and compressors of any brand where there is no socket.
Like a portable professional power supply, but with 2,134 Wh of energy and 16 A continuous load – emission-free, quiet and ready to use instantly.
Charge Hilti chargers (e.g. Nuron) and devices off-grid via the 230-V Schuko outputs – no generator, no exhaust fumes.
Supplies Stihl battery chargers and garden tools with clean 230-V power – ideal for landscaping teams without a fixed mains connection.
Four devices in the same 3,600-W class. The GM 3600 is the affordable alternative to the premium units – the same 3,600 W continuous power, 18 kW peak and IP54, yet significantly cheaper.
