Split Charge - CTEK Battery-to-Battery for Vehicles with Smart Alternators


Price:
£272

Description

This is a modern split charge system built around a DC-to-DC charger with a built-in solar & wind controller. It is more efficient than traditional split charge relays, meaning your leisure battery will charge faster while you drive.

Smart Alternators

It is suitable for all vans, including those with a smart alternator (usually 2013 or newer vehicles, although that varies). If you have a Euro cat 5 or 6 engine you will definitely have a smart alternator.

The D250SE will still operate even if the smart alternator is shut off and maintain a stable output of up to 20A to fully

charge your battery in the shortest time.

Why This Charger?

The D250SE automatically delivers the optimum charge so your batteries are fully charged in the shortest possible time. You

can select normal or 14.7V AGM charge voltages. It also has a temperature sensor to compensate for hot or cold conditions and avoid the risk of your battery overheating or overcharging.

Built-in Solar Charging Controller

The D250SE has an input for connecting solar panels without the need for a regulator. It also features a Maximum Power

Point Tracker (MPPT) to get the maximum power out of your solar panels.

Additional Solar Panel MPPT Information for Ctek D250SE

The maximum open-circuit voltage from the panel is only 23v. We recommend using only 100-watt panels or 150-watt panels.

This can be up to 3 x 100-watt or 2 x 150-watt panels if required.

Always check the panel specification as a higher voltage

will damage the charger and will invalidate the warranty.

Choosing a Kit Length

The kits are sold based on the length of red cable required. This is the cable that is run from the main battery to the location of your leisure battery. It is made to the length you pick with 2 x 250mm cables and the rest of the length as 1 long cable. This allows you to put a fuse between the main battery and the relay, and another between the relay and the leisure battery.

It's always worth slightly overestimating the length required as the kit comes with pre-made cable ends. Run a length of string along the path you intend to run your cables then add a metre (or two if your run is complicated with lots of turns).
