The EVO22KSEm 27kVA / 22kW (Standby) | 25 kVA / 20 kW (Prime) Diesel Generator. 230v Single Phase.

Designed by Evopower. Powered by HY4102 Diesel Engine. Controlled by ComAp MRS10 Control Panel.

The single phase 230 volt 20kW / 25kVA (Prime) and 22kW / 27kVA (Standby) rated EVO22KSEm diesel generator, is powered by an Evopower diesel engine which runs at 1500rpm. As with all Evopower generators, this is ATS/AMF/MTS compatible. The 22kW EVO22KSEm has a ComAp MRS10 control panel.

The EVO range of generators have powder coated, weatherproof canopies. The canopy reduces the sound level on this unit to only 66dB at 7m while on 75% load and provides a certain amount of protection from the elements, along with lockable doors for security and safety.

With all of our diesel generators, this UK specification, UK designed backup, slow running generator uses high quality components such as the 4 cylinder, inline 3.8L HY4102 engine coupled with a Genpower 184F AVR brushless alternator and a ComAp MRS10 control panel.

Our 22 kW / 27 kVA EVO22KSEm holds 93 litres of diesel within the base tank in the skid of the unit. The 93 litre diesel tank provides a run time of 10.3 hours on 100% load. With all of our Evopower generators, you can use red diesel to save on running costs, without any fear of voiding your warranty.

The base mounted diesel tank is integrated within the heavy duty skid, complete with fork holes for easy unloading/moving and hook eyes to help keep the machine stable while transporting or lifting into position. More detailed specifications on individual components we have used in our generator can be found within the pdf downloads available.

Powered by a HY4102 4 cylinder 3.8L engine
The Evopower EVO22KSEm slow running diesel genset is powered by a HY4102 water cooled diesel engine and is mechanically governed to run at 1500RPM to maintain a stable 50Hz output from the alternator. The AVR protection ensures the output is safe for us with any sensitive electronic equipment.

The engine oil capacity is 7.5L and we recommend using SAE 15W40 oil, and using a 50/50 mix for the coolant/radiator fluid of 50% water and 50% ethylene glycol (anti-freeze).

Controlled by a ComAp MRS10 control panel.
Our entire EVO range of single and three phase diesel generators use an advanced ComAp MRS10 control panel. The control panel is packed with safety features to protect your slow running diesel genset, and is compatible with ATS / auto-start / MTS / manual changeover switches. ATS panels automatically transfer your load or house from mains supply to generator without any interaction needed in the event of a power cut.

Optional extras for the ComAp panel include GSM remote control connection and Ethernet connectivity, so you can monitor the location, safety alerts, warnings and start/stop your generator using your mobile, PC or laptop. Contact us if you would like more information on these options.

The control panel has many built in features to prevent damage to the generator, and will notify you with alerts such as;

  • Low oil pressure -  which can lead to a lack of lubrication and engine damage,
  • High water temperature - which could be a sign that the radiator air flow is blocked or water level is low.
  • High or low voltage detected - which could signify a problem with the alternator, AVR, or degrading electrical connections and lead to your equipment being damaged.
  • High or low frequency or engine over/underspeed - which could signify an issue with the fuel regulation/governor and leads to unstable frequency output.
  • There are also built in features such as start/stop issues and more.
  • Ask us about expanding the features of your control panel with our GSM (mobile SIM card) or Ethernet connection options.

Please note that there are certain regulations in certain areas and countries related to noise, fuel storage and emissions. Please make sure you order the correct generator for your region/location.

The kVA ratings stated are based on the assumption that your load/appliances will have a power factor of 0.8. When you receive the generator, you will notice the spec place on the set lists it as 8.8kW / 8.8kVA with a power factor of 1 (unity). Without being too technical, this is due to the fact the generator itself is in unity and produces a power factor of 1 between the engine power and alternator output. kVA is a rating of 'apparent' power and takes into account expected losses within a circuit - like energy being wasted as heat when you run a light bulb. Most loads have losses and it is generally accepted to base the assumption on a power factor of 0.8 when you do not know. We would recommend basing your decision for which generator you need on the amperage draw you require, taken and assessed by a suitable, qualified expert. Feel free to contact us is you require a little more detail on apparent power vs. actual or real power.

The full service schedule can be found within the manual sent with your genset. The general guide is to change the lubricant/engine oil every 250 hours or 6 months.

This unit holds 7.5 Litres of lubricant / engine oil. We recommend using SAE 15W40 engine oil.

The replacement filter numbers for easy ordering are:

Air Filter(s): K1317
Oil Filter(s): JX0814-T (Blue)

We also offer replacement sensors, belts, starter motors and more for our Evopower EVO range of single phase and smaller output 3 phase gensets. Get in touch if you need any advice or guidance over spare parts for your generator.


The limited warranty terms are 1 Year or 1,000 hours (whichever comes soonest), however, if used for standby and you have run below 500 hours in year 1, please send us your service record and proof of hours in month 13 and we can extend your warranty for another 12 months and 500 hours (so 24 months and 1,000 hours in total, but less than 500 hours per year and services accordingly).

All warranties are subject to terms and general wear and tear or serviceable parts, and any failure due to lack of maintenance in line with guidelines are not covered. We will send out replacement parts free of charge for any warranty claims.

Please contact us if you require any more detailed information.


Evopower Cummins Powered Generator Warranty Emblem


The limited warranty terms differ depending upon the model and manufacturer of engine we use - whether it is our own, Cummins, Hyundai, Perkins...etc, and the location of the generator.

For UK based installations, our Cummins powered ECO range of three phase diesel generators have a warranty up to 24 months / 1,000 hours for standby applications or up to 12 months / 2,000 hours for prime applications.

In order to activate your extended warranty terms on the Cummins ECO range you must complete a few steps. For standby applications, if you have used your genset less than 500 hours in year 1, send us the service records and proof of hours in month 13 from purchase and we will extend your warranty for 12 months / 500 hours (max of 24 months, 1,000 hours).

For Prime applications, servicing and maintenance is key to prevent downtime. To extend the warranty from 1,000 hours to 2,000 hours simply send us a picture of the hours clock, and proof of servicing works within 14 days of each service to receive a warranty that lasts 2,000 hours. Please read the full warranty document to ensure you make the most of your free warranty.

All warranties are subject to terms and general wear and tear or serviceable parts, and any failure due to lack of maintenance in line with guidelines are not covered.  Please contact us if you require any more detailed information on any of the warranty terms.
