3600W Welling & Crossley Portable Power Station WC-BG3600

The WC-BG3600 is a battery power station from Welling & Crossley, rated at 3600W continuous with 7200W maximum (surge) output from a 3,840Wh LiFePO4 battery. It has no engine, fuel or exhaust: 240 V AC comes from a built-in inverter, alongside USB, 12 V DC and wireless charging outputs, and the battery recharges from a wall socket or from solar panels through the built-in MPPT controller.

Key features

• 3,840Wh LiFePO4 battery: lithium iron phosphate cells with generator-class capacity, enough for a camp fridge for about three days.
• 3600W rated, 7200W surge: runs higher draw appliances and tools, with headroom for motor start-up.
• 2200W AC charging: recharges to 80% from a wall socket in approximately 100 minutes.
• 2400W solar input: 10 to 150 V DC through the MPPT controller, for substantial off-grid charging.
• Four 240 V AC outlets: 15 A pattern sockets within the 3600W rating.
• 12 V 30 A output: a high current 12 V DC outlet (360W max) for 12 V fridges, pumps and accessories.
• Pure battery operation: no engine, fuel or exhaust, so it can be used indoors and on noise-restricted sites.

From a wall socket it recharges to 80% in approximately 100 minutes (2200W AC input). Run time is load dependent: as listed for this model, a 45W camp fridge runs for about three days, a 100W load for over 30 hours. Outputs: 4 x AC 240V/50Hz/15A (3600W, surge 7200W); 4 x USB-A 25W; 2 x USB-C 100W; 1 x Car Charger 12V/10A; 2 x DC5521 12V/10A; 1 x DC 12V/30A 360W max; 1 x Wireless charging up to 15W. Inputs: AC Input 230V 50Hz 2200W max; Solar Input 10-150V DC 2400W max (MPPT).

What it will run

With 3600W continuous it typically handles a fridge and freezer together with lighting and electronics, or higher draw items such as a kettle, microwave, induction cooktop element, drop saw or compressor within the rating. Run time falls as load rises, so divide the battery capacity by the total watts you plan to draw for a rough estimate, and allow for inverter losses. Check the rating plate on each appliance, and remember that motor loads such as fridges, pumps and compressors draw a start-up surge well above their running watts.

The WC-BG3600 suits home backup, noise-restricted worksites and indoor fit-outs, events, film sets and catering, and off-grid cabins with a solar array, recharged overnight or from solar between uses. The WC-BG5500 is the flagship at 5500W.
