Sargent EC800 Series Systems

Whether you can depends on which type of Sargent PSU system you have - manual-charging or CAN-bus based.

On systems that only charge manually - PSU2007 with EC200, EC328, EC325, EC225 with EC100, EC176 with EC361/2/3, and EC155 with EC50/51 - the leisure battery is charged by default: with the control panel switched off, the mains charger starts charging the leisure battery the moment it's plugged in, and with the panel on, it keeps the leisure battery topped up while also powering the leisure loads. To charge the vehicle battery instead, switch the control panel on and pick the vehicle battery - the charger then charges that battery along with any leisure loads left switched on. Note that EC100, EC200, EC325 and EC50/51 panels won't allow the vehicle battery to be selected below 10.9V, while EC328 panels (software V2.21) will allow it above 2V provided the mains charger is on. If mains power is lost while charging the vehicle battery, leisure loads will start drawing from it instead - switching back to the leisure battery once the vehicle battery either falls below the 10.9V cut-off or, if it started above that, once it recovers back up to 10.9V. The leisure battery itself has its own 9V cut-off that disconnects leisure loads to stop it discharging further.

CAN-bus systems (the EC800, EC700, EC600, EC500, EC450 and EC400) include a smart-charge feature instead, on by default but switchable off. With the mains charger on, it defaults to charging the leisure battery while keeping an eye on the vehicle battery - if that drops below 12.4V, charging switches to it for 4 hours, then returns to the leisure battery for another 4 hours, repeating the cycle for as long as the vehicle battery stays low. This runs regardless of whether the control panel is on, as long as the system's own shutdown button is switched in (unless you've disabled the feature) - and if the panel is on, you can manually pick whichever battery you want charged at any point in the cycle.

Start by switching the EC700 PSU off, then switch the shutdown button on again while continuously tapping the control panel screen. Once the system powers up you'll see a blue screen prompting you to touch 3 dots - do that, and the panel will show 'calibrated' on the blue screen, then go back to its usual display, completing the process.

Start by switching the EC800 PSU on and powering up the control panel via its power button. Then press and hold that power button - after 5 seconds the screen goes off, but keep holding for another 15 seconds until a blue screen comes up asking you to tap 3 dots. Do that, and the panel will show 'calibrated' on the blue screen, then go back to its usual display, completing the process.

Most Sargent systems use a PX300 or PF200 battery charger. If yours has a different charger fitted, check with that charger's own manufacturer for Lithium compatibility. The PX300's charging profile suits many leisure-industry Lithium batteries that have their own internal Battery Management System (BMS) - its charging profile and voltages are available as a downloadable attachment on the PX300's own product page, though you'll still need to confirm suitability directly with your chosen battery's manufacturer.

Systems that use a PX300 include the EC800, EC700, EC600, EC500, EC400 series, EC400+ and EC328. If your system doesn't have a PX300, its charger will run a fixed 13.8V, which generally isn't suitable for fully charging a Lithium battery - and switching to Lithium may also mean you need a DC-DC charger to keep the charging current within limits.

We don't endorse any particular make or model, but the PX300 charger (fitted across the EC400/EC400+, EC500, EC600, EC700, EC800 and EC328 systems) suits the great majority of good-quality AGM batteries sold in the UK. Its charge profile is included in the instruction manual attached to its product page - if you're at all unsure whether a battery is compatible, check with that battery's own distributor or manufacturer first.

Your device needs to support Bluetooth 4 / Bluetooth Low Energy (BLE). If you're not sure, a Bluetooth-checking app such as LightBlue® (available for both Android and iOS) will confirm it - a compatible device should show a Bluetooth source named SWIFT_BLE; if that never appears, your device most likely isn't compatible.

1. Make sure there's a leisure battery fitted and, where needed, that the mains charger is on.
2. Check the EC600 or EC800 PSU's shutdown button is pushed in (system powered up).
3. Turn on the control panel (EC600 or EC800).
4. On an EC600, go to the EC620 screen and use select (right arrow) to step through the system info, confirming it reads 90C90 (caravan) or 91C91 (motorhome) or higher, SW13, and a valid Mxxxxxxxxxxxxxxx IMEI number.
5. On an EC800 panel, tap the settings cog on the Home Screen and check EC630 No. reads 34 or higher, with a valid Mxxxxxxxxxxxxxxx IMEI number.

That's completely normal - the app can disconnect right after first pairing, and you just reconnect to carry on using it. The Bluetooth link also drops whenever your device sleeps, its screen locks, you change to a different app, or a different paired device takes over the connection - simply reconnect when you want to use Swift Command again.

You can extend your device's auto-lock/sleep timer (iOS: Settings > General > Auto-Lock; Android: Settings > Display > Screen timeout) if this happens too often. Also worth knowing: using the app's remote features while connected via Bluetooth inside the vehicle disconnects that Bluetooth link for 5 minutes afterwards, to avoid the two signals clashing.

You've got 1 minute to complete pairing. In your device's Bluetooth settings, SWIFT_BLE should appear as an available device - tap it to pair, and it should then show up in your paired devices list. Back out of settings, open Swift Command, tap the Bluetooth icon then Search for Control Panel to list nearby systems, and tap the one you want to connect to your EC600 or EC800. Press back to go to the home screen, and you can start using the app.

You've got 1 minute to complete pairing. Inside Swift Command, tap the Bluetooth icon then Search for Control Panel to list nearby systems, tap the one for your EC600 or EC800, and confirm Pair when the pop-up appears. Once paired and connected, press back to go to the home screen.

A Swift Command account is what unlocks features like remote alerts, remote level readings and remote control - and you'll need one regardless if you want to add a tracking subscription.

Account details - name, address, email, phone number and the vehicle's serial number - are held on a secure Microsoft server and shared with Sargent Electrical Services, The Swift Group and registered Swift Group dealers/engineers. Vehicle system data (battery voltage, water levels, temperature, humidity and GPS location) is stored the same way and shared with the same parties, purely for diagnostics, analysis, and providing support.

None of this is passed to any other third party, except where legally required by a court, government agency or the police.

Any Swift Command caravan or motorhome with either an EC600 Power System paired with an EC620 Control Panel, or an EC800 Power System with its own EC800 Control Panel, is compatible. Some 2016-built caravans have the remote features but not the tracking option, though.

Subscribe through the current Swift Command website - register an account first at www.swiftcommand.co.uk if you don't already have one. From the homepage, open the Vehicles section to see what's linked to your account, click through to the vehicle you want tracking on, and scroll down to pick a subscription length. If no vehicles show up under Vehicles, that means yours hasn't been linked yet - only Swift Group registered dealerships can do that, so you'll need to contact your dealer.

Selling privately? Email support@swiftcommand.co.uk to transfer the vehicle to the buyer's account; selling through a Swift dealership, they'll handle the transfer for you.

A 3-year data subscription is included with every vehicle, covering communication and remote control, and you can add tracking whenever you like, lasting 1, 2 or 3 years. On top of an existing data subscription (which has to cover the whole tracking period), tracking alone costs £100/£200/£300 for 1/2/3 years; combined tracking and data costs £135/£250/£365 for the same periods.

Beyond year 4, without tracking, a data-only subscription costs £45/£70/£90 for 1/2/3 years. You've got 14 days after buying tracking to change your mind and get a refund - none are given after that. These are Sargent's prices as listed on its help site in 2026 - check the current price before buying.

If the vehicle moves while the tracker's armed, geo-fencing flags a possible theft and the monitoring station gets in touch to confirm it's genuine (or a false alarm) by checking your identity. On a caravan, arming happens automatically when you arm the Stinger 310/350 alarm, or via the tracking keypad if there's no alarm fitted; it disarms the same way.

On a motorhome, it arms as soon as the ignition's switched off. Swift Command Tracking itself is a proactive system approved to Thatcham category S7.

Thatcham Research is the UK body that assesses and certifies safety and security products on behalf of insurers - and Swift Command Tracker carries their Quality Assured Category 7 approval.

You'll get an emailed certificate once your tracking subscription is activated, listing your vehicle and the period covered, which you can print again whenever you like from your Swift Command account via the vehicle's Document heading. The Vehicles section of your account also shows the subscription status directly.

How much solar you can add through the PSU comes down to the fuse protecting that circuit, which varies by system - the maximum recommended wattage through the PSU is 120W for EC325/EC328/EC500/EC600, 80W for EC400, and 150W for EC700/EC800/EC400+. You can go beyond that by wiring extra panels straight onto the leisure battery via their own regulator and a correctly-sized fuse, though you'll lose the ability to see that extra solar's output on the control panel.

Any system without a PSU solar input at all needs its solar wired directly onto the leisure battery this way regardless - and there's no upper wattage limit when connecting straight to the battery like this.
