Warrior LDG6500SV 5.5kW Silent Diesel Generator

When the lines go down, turn a key and get 5kW of diesel power back. The Warrior LDG6500SV keeps an oil boiler, borehole pump and the rest of your essentials running from a soundproofed canopy, with up to 12.4 hours from a half-loaded tank. It also has a port ready for automatic start, which the remote-control version doesn't.

Why buyers choose the LDG6500SV

• 5kW continuous, 5.5kW maximum. A 474cc direct-injection diesel engine, EU Stage V compliant.
• Ready for automatic start. The built-in ATS input links to the optional Warrior ATS panel, which starts the generator when the mains fails and stops it when power returns.
• A long run on one tank. Up to 12.4 hours at 50% load from 16 litres, with a fuel gauge so you can plan ahead.
• Protected as standard. Low-oil shutdown guards the engine, overload protection guards the output, and AVR holds the voltage steady.
• Quieter by design. A soundproof canopy and anti-vibration mountings bring it to 68 dB(A) at 7m.
• Simple to run. Electric key start, an electric fuel pump, and a 3-in-1 display for voltage, frequency and run time.
• Two voltages. One 240V 32A outlet and one 110V 32A outlet, plus a 12V terminal for charging car-type batteries.

Is it right for you?

Ideal for: power cut backup at rural homes, off-grid and island properties, oil boilers and borehole pumps, small premises, and occasional construction or catering jobs.

Look elsewhere if:

• You'd rather start it from a key fob. The remote start LDG6500SVWRC does that, but has no ATS input for automatic start.
• You want longer between refuels. The Hyundai DHY8000SELR Long Run is built for it.
• You mainly run laptops and other sensitive electronics. AVR helps, but an inverter generator gives cleaner power.
• You need three-phase. See our three-phase generators.
• You need power every day. This is a 3000rpm generator for backup and infrequent use, so ask us about a 1500rpm set.

What will it run?

Plan around the 5kW continuous output. The 5.5kW maximum is only for short bursts, and the manual says never to run at maximum for longer than 10 minutes. Motors can draw three times their running watts or more when starting, so check the rating plates on your own equipment.

Rural home example: oil boiler 250W + 1,000W borehole pump + fridge freezer 150W + lights 100W + TV and router 200W comes to about 1,700W, which leaves around 3,300W in hand. If the pump pulls three times its running watts as it starts, the brief peak is about 3,700W, still inside the 5kW rating. Start the pump first, then bring on other loads.

On the 110V outlet: expect only around 50 to 60% of the rated output, so about 2.5 to 3kW.

How long will the fuel last?

At half load, a 24-hour power cut will take about two full tanks, or 32 litres. Lighter loads last longer and heavier loads less. Keeping fuel on site makes sense if you're rural, and a 20-litre steel jerry can is a good start.

Use clean light diesel only. Never use petrol, kerosene or biodiesel. Warrior doesn't recommend dyed diesel, such as red diesel, and if you do use it, the manual strongly recommends monthly maintenance.

Connecting it to your property

To power your property's circuits, the generator must connect through a transfer switch fitted by a qualified electrician, so that it and the mains can never be connected together. Never feed it through a socket. Neither switch is included.

• Manual switch: you start the generator and turn the switch yourself.
• Warrior ATS panel (part 190102000010): starts the generator for you and stops it when the mains returns, which suits properties often left empty.

Important for your warranty: Warrior's terms say that any manual or automatic transfer system not supplied under the Warrior or Champion name will invalidate all warranties. Please speak to us before you buy or install one.

Where to put it

• Choose a flat, level, solid base outdoors, at least 1.5m from buildings, structures, windows and doors.
• It isn't waterproof, so it must never be exposed to rain, snow or water spray. Plan this before it arrives.
• Never run it in a shed, garage, outbuilding or vehicle. As well as being dangerous, Warrior's terms exclude this from the warranty.
• 68 dB(A) at 7m is quieter than an open-frame diesel, but you'll still clearly hear it, so keep it away from bedrooms and neighbours.

Getting it running

• Delivery: at 168kg it arrives on a pallet, so have a pallet truck or mechanical lifting ready. The wheels are for firm, level ground only.
• Add engine oil. It's shipped dry and takes 1.1L. Warrior recommends 10W-30 part or full synthetic. Check the dipstick on level ground.
• Add clean diesel, and check the fuel line for air, as the manual describes.
• Check the battery is connected before first start.
• Earth it. The manual recommends heavy wire from the earth terminal to a rod or stake at least 200mm deep. The rod isn't listed as included.
• Start with no load attached, then let it settle.
• Run it in gently. Keep below 75% load for the first 10 to 20 hours.
• Use the right plugs. The outlets are 32A industrial-style sockets, so use matching plugs, a transfer switch, or a suitable splitter box for 13A appliances.

Delivery note: Warrior generators can take 2 to 5 working days to arrive. If you need one by a certain date, please contact us before ordering and we'll confirm availability.

Keeping it ready

Start it regularly between power cuts so that it's ready when you need it. Some items need a service engineer, and the manual marks which ones.

FAQs

Is it really silent? "Silent" is the name for this canopied design. It's much quieter than an open-frame diesel, but it's still a diesel engine. Some owners call it fairly quiet, and others find it louder than they expected.

Can I extend the exhaust to reduce the noise? Please don't. Warrior's warranty excludes exhaust extensions, and exhaust gas is dangerous. Choosing a position further away is the safe way to reduce noise.

Can it start automatically? Yes, with the optional Warrior ATS panel, which connects to the port already fitted.

Will it run a borehole pump? Usually yes, but pumps draw a large current at start-up. Send us your pump's rating and we'll check it.

Can I plug in normal appliances? Not directly. The outlets are industrial-style 32A, so you need a matching plug, a suitable splitter box or a transfer switch.

Will it start in freezing weather? The manual describes a preheat button for temperatures below 0°C. With the key on, hold it for at least 5 seconds until the red light is solid, then start as normal.

Can I charge a battery from it? Yes, but only 12V car-type batteries using the DC terminals, and never use the DC and AC outputs at the same time.

Why might it say Bimson Power? Warrior's UK distributor also sells this model under the Bimson Power name, so your generator or its paperwork may carry that branding.

Is it for everyday use? No. It's designed for backup and infrequent use. For daily running, ask us about a 1500rpm generator.

How does the warranty work? For domestic use, you get parts and labour in year 1 and parts only in year 2, up to 1,000 hours. Commercial use is 1 year or 500 hours. Hire use isn't covered, batteries are limited to 1 year, and carriage for repairs is at your cost. You don't need to register, but keep your proof of purchase and service records.

Not sure it's the right size? Send us your appliance list at sales@generator-uk.co.uk or call 01744 520110, Monday to Friday, 8:30am to 5pm, and we'll help you size it.

Safety: run outdoors only, at least 1.5m from buildings and well away from doors, windows and vents. Generator exhaust contains carbon monoxide. Let the engine cool before refuelling.
