It supplies 230V through two 13A UK sockets and has a separate 12V output for charging batteries. Use it to run lighting, chargers and small 230V tools wherever there is no mains supply.
A basic generator lets its voltage rise and fall each time a tool or light switches on or off. Those swings shorten the life of chargers and electronic controls, and can trip sensitive equipment mid-job. The automatic voltage regulator here adjusts the alternator continuously, so the output stays steady as the load changes.
Automatic voltage regulator: holds a steady 230V as loads switch on and off, which protects chargers and electronic controls.
Two IP54 13A UK sockets: standard 3-pin plugs fit straight in, and hinged covers keep dust and splashes out when a socket is not in use.
12V DC charging output: charges 12V batteries up to 40Ah at 8.3A, with its own DC breaker.
2000W continuous output: runs a mix of lights, chargers and small tools at the same time, with 2200W available for short start-up peaks.
15L fuel tank: gives about 10 hours of running between refills.
Low oil pressure shutdown: warns of low oil and stops the engine automatically before damage is done.
Tubular steel frame: protects the engine and control panel from knocks in the van and on site, while anti-vibration mounts reduce shaking.

Maintenance, grounds and mobile service teams use this generator on jobs away from a mains supply, such as estates, car parks, farms and outdoor events. It suits 230V equipment that plugs into a standard 13A socket. Operators need no specialist training beyond the manual, but should understand load limits and safe refuelling.
Charging cordless tool batteries, radios and phones at remote jobs with no power.
Running 230V lighting, a payment terminal and a PA system at outdoor events and market stalls.
Powering small 230V hand tools for grounds and estate maintenance away from buildings.
Running diagnostic equipment and laptops for mobile technicians at the roadside.
Charging 12V lead-acid batteries on vehicles and plant through the DC output.
Keeping essential 230V equipment such as a fridge or freezer running during a power cut, plugged directly into the generator.
Step 1: Place the generator outdoors on firm, level ground, well away from doors, windows and air vents.
Step 2: The generator is supplied without oil, so fill the engine with about 0.6L of SAE 10W-30 or 10W-40 before first use, then fill the tank with unleaded petrol.
Step 3: Connect the earth terminal to an approved earth using wire over 0.75mm2 before connecting any equipment.
Step 4: With nothing plugged in, set the engine switch to ON, turn the fuel tap on and close the choke. Pull the recoil cord sharply until the engine starts, then move the choke to run once the engine is warm.
Step 5: Check the voltmeter reads correctly and the AC breaker is on.
Step 6: Plug in the largest load first, then add smaller loads, keeping the total within 2000W.
Step 7: Unplug all equipment, switch the engine off, then turn the fuel tap off.
“Refuelling while the engine is running” is replaced by “Leaving a battery on charge unattended, when the unregulated DC output does not cut out once the battery is full.” Refuelling is still covered in Safety.
Exhaust gases contain carbon monoxide, so run the generator outdoors only and keep it away from openings into buildings. Switch off and let the engine cool before refuelling, and store petrol in approved fuel cans. Use an RCD between the generator and any 230V tool used outdoors. On construction sites, HSE guidance favours 110V tools, so check site rules before using 230V equipment. The sound power level is 95dB(A), so wear hearing protection when working close to the generator for long periods.
Check the oil level before every use. Change the oil after the first 8 hours, then every 50 hours, and keep loads under 75% for the first 25 hours. Clean the air filter element in a mild solvent, then lightly oil it before refitting, more often in dusty conditions.
Q: What can a 2200W petrol generator run?
A: It can run any 230V equipment whose combined running load stays within 2000W, the continuous output. Add up the wattage on each item’s rating plate before plugging in. Motors in compressors, fridges and saws can draw far more than their running wattage as they start. Start the largest load first and leave some headroom.
Q: What do 2200W and 2000W mean on a generator?
A: 2200W is the maximum output, which the generator can only hold for short periods, such as while a motor starts. 2000W is the continuous output it can supply for hours at a time. Size your loads against the 2000W figure. The “T2500W” in the model name is a model reference, not an output figure.
Q: How long will it run on a full tank?
A: The supplier gives a runtime of about 10 hours from the 15L tank. Actual runtime depends on the load, and lighter loads use less fuel. Check the fuel level before a long shift and keep a filled fuel can nearby.
Q: What is this generator not suitable for?
A: It is not suitable for indoor or enclosed use, for 110V site tools, or for loads above 2000W continuous. It should not be connected into building wiring unless a qualified electrician fits a changeover switch. The 12V output is for charging batteries, not for running 12V equipment.
Q: Why choose a generator with AVR over a basic frame generator?
A: An automatic voltage regulator holds the output voltage steady as loads switch on and off. Without one, the voltage can dip and surge, which is hard on chargers and electronic controls. The supplier rates this AVR output as suitable for more sensitive equipment, including electronics. For the cleanest possible output, an inverter generator is the step up.
Q: Can I run 110V site tools from this generator?
A: Not directly, because it has two 230V 13A sockets and no 110V outlet. HSE guidance favours 110V portable tools on construction sites. For site tool power, choose a generator with a 110V outlet.
Q: How do I charge a 12V battery from the generator?
A: Connect the battery to the red and black 12V DC terminals, observing polarity. The DC output charges 12V batteries up to 40Ah at up to 8.3A. It is unregulated and does not cut out when the battery is full. Do not leave a battery charging unattended for long periods.
Q: Can we manage generator and fuel orders across several sites?
A: The free EDGE procurement portal sets budgets, delivery addresses and users for each project. Teams can order generators, fuel cans and site consumables in one place, with live pricing, stock and tracking in the EDGE App. Punchout, EDI and API links connect it to your own purchasing system. EDGE is free to use with CMT Group.
Q: Can it be delivered to a job with no postcode?
A: Deliveries can be sent to a What3Words location, accurate to a 3m square, so the driver reaches the right gate or compound. Our own delivery fleet covers over 95% of the UK mainland, with no third-party courier. Live tracking shows the ETA and a photo proof of delivery.
