General

For generators used under normal conditions in our temperate climate zone, a mineral oil (e.g., 15W40) is sufficient. The semi-synthetic all-rounder oil 10W40 works just as well and is priced similarly to 15W40. If temperatures rise above 35°C, using 10W50 is recommended to ensure the oil film doesn’t break.

To ensure your generator has a long life, we recommend our high-performance oil, Super Blue with Special Additive. This ensures the best lubrication and running properties.

Inverters are electronic components that take the power generated by a converter generator, filter it, and convert it into a pure sine wave. Unfiltered power from a converter, like many models from Kipor’s red line or other OEM generators, contains voltage spikes and fluctuations. These peaks can quickly damage sensitive devices.

Many manufacturers now state in their warranty terms that operating devices on a generator without inverter technology voids the warranty. We offer the best inverter generators from renowned manufacturers such as FME, Voltherr, and Champion.

Traditional converter generators without inverter technology can have voltage deviations of up to 23%. At an output voltage of 230 volts, your device may experience short voltage spikes exceeding 280 volts. This is a slow but certain death for most electrical devices.

The following devices are just a few examples that rely on an inverter to avoid damage:

  • Televisions, computers, monitors, radios, stereo systems, music amplifiers, measurement devices, satellite receivers
  • Some refrigerator models
  • Battery chargers for motorhomes that use the grid frequency for control
  • Compressors for air conditioners and refrigerators in motorhomes
  • Grid-frequency controlled chargers for expensive video cameras, smartphones, cameras, etc.
  • Microwave ovens
  • Induction cooktops

The list goes on. There are few electronic devices that do not require a pure sine wave, such as older power tools without speed regulators or simple angle grinders. A generator with inverter technology is the best choice to cover a wide range of applications as technology continues to advance.

We frequently receive inquiries from customers whose generator batteries have failed. The common complaint is, “I haven’t used the generator for six months, and now that I need it, it won’t start.” It’s easy to assume this is a technical issue and that the battery is still under warranty, but this is rarely the case.

Lead-acid batteries are perishable goods. Contrary to popular belief, simply disconnecting the battery isn’t enough. It must be regularly charged and maintained to prevent deep discharge. We recommend the following steps to properly maintain your battery and extend its lifespan:

  • Unused batteries should be charged every three months at the latest (avoid discharging the battery below 80% of its capacity, as this can significantly reduce its lifespan).
  • Store the battery (or the generator containing the battery) in a cool (below 25°C), frost-free, and dry location.
  • Use only special AGM chargers for lead-acid batteries.

Improper use and failure to follow our maintenance recommendations voids all warranty and guarantee claims.

We often get asked what starting or inrush current is.

Starting or inrush current is the current a device requires at the moment it is switched on.

This inrush current varies depending on the type of device. For example, inductive loads, like devices with electric motors, can have a starting current multiplier of x4 or more.

For instance, a 2kW circular saw has an inrush current of around 8kW at startup because it is an inductive load.

In addition to inductive loads, there are resistive and capacitive loads. Resistive loads, like a heat gun, typically have an inrush current multiplier of 1.5-3x. Capacitive loads, like phone or laptop chargers, have a multiplier of 1-1.5x.

An ATS (Automatic Transfer Switch) box is an automated version of a mains isolation switch.

Both ATS boxes and isolation switches are used to ensure your home network is disconnected from the grid when power is supplied by a generator.

While a manual isolation switch requires you to disconnect the house from the grid manually, the ATS box does this automatically. It detects when the grid power fails and signals the generator to start.

The ATS box then isolates your home network from the grid and connects the generator to restore power to your selected devices. This process usually takes between 7 and 20 seconds.

If a generator with an internal combustion engine fails to start, the issue is either a faulty ignition system or inadequate fuel supply.

Check for a spark by inspecting the ignition system and replacing the spark plug. Often, a faulty spark plug is the issue.

If there is a spark during startup attempts, the problem likely lies with the fuel supply. Ensure the tank is full and the fuel valve is open. Multiple start attempts usually push fuel into the carburetor, enabling the engine to start. Using starting fluid for gasoline engines can help facilitate this process.

However, the carburetor could also be clogged.
