Plasmatronics DINGO 4040P 40A PWM Solar Controller for 12-48v Systems - Lithium Compatible (user programmed)

Max. Solar Currant: 40A

The Dingo4040P is the next generation charge controller from Plasmatronics. It inherits many of the best features of the PL series of controllers. But, thanks to Plasmatronics extensive industry experience and a wealth of customer feedback, the Dingo2020N is in a class of its own.

The Dingo Series controllers were designed to be used in Caravan / Camping / Marine applications as well as Stand Alone Commercial and Industrial ones. However, the main applications its designed for is vehicle systems, such as Campervan, Motor-home, Caravan, Cars, Trucks and boats. As Its easier to understand for people used to working on vehicle systems, due to the Negative grounding

The Dingo series of solar controllers is exceptionally versatile. They give the user unparalleled capability to adjust the function of the controller and to monitor the performance of the energy system.
To cater for non technical users, the Dingo has four preset programs which can be used without needing to understand the details of its operation. For those with a good understanding of solar regulation, there is another program, which allows all the settings to be adjusted if required.
Once the program has been selected, it is possible to disable any further adjustment. This prevents unauthorised adjustment of settings.
Although the Dingo is primarily a device to control the charging of batteries from solar electric (photovoltaic) panels, it can also be used with other energy sources such as wind, micro hydro and fuel driven generators.
The Dingo supports a variety of regulation methods. It supports slow speed switching and fixed frequency pulse width modulation (PWM) control in series and shunt modes.
Low battery voltage load disconnection is provided, as are an alarm, facility to control the charging of a second battery bank and control for a back up generator. The event controller can be used to control lights, pumping, waste energy use and other timer functions.
A temperature sensor can be added to correct the regulation voltages for battery temperature.
There is an input for measuring external voltages.
A serial interface is provided for accessories including extra switch blocks, remote current sensors and communication with a computer/ modem.
Using an external current shunt attached to a remote current sensor (DSA) allows the controller to see other current flows in the system.
The Dingo can control larger systems by adding external switch blocks attached to the serial bus.
The DUSB, D232 or DNET interfaces allows remote monitoring and adjustment. Custom settings can be stored on a computer and uploaded into the controller. Data from the controller can be downloaded into the computer and displayed easily.


What’s the same:

  • Reliable, easy to understand, one button interface and proven, easy to learn menu structure.
  • Symmetrical charge and load currents, both 20A.
  • Industry standard four stage charging regime.
  • 12,24,32,36 and 48V selectable. Only one controller to stock.
  • Unbeatable high temperature performance. Full charge and full load current, without interruption to operation, in a 50oC ambient. All day, every day.
  • Fast, reliable, affordable, Plasmatronics Service, long after the long warranty has expired.

What’s new? Nearly everything else! Without any exaggeration, much too much to list here. Highlights include:

  • Negative Ground: This makes it much easier to use in vehicles and easier to understand for people used to working with vehicle systems. The Dingo works well everywhere, but shines in campervan's, motor homes, caravans, cars, trucks and boats.
  • New Communications Bus: This rugged new bus uses the MODBUS protocol (industrial automation standard proven in noisy environments). Aside from accessories you would expect for a PL descendant like shunt adaptors and data interface units, it is also compatible with Modular System Components. This gives unprecedented flexibility in system design.
  • More Data Storage: 512 days worth of data can be stored. That’s 16 Months worth of Charge and Load Ah, Battery voltage range, and daily State of Charge. Data for 99 days is accessible via the display so if you don’t have a computer, you’re not locked out.
  • Enhanced one button interface: Now includes Reverse gear for when you want to go backwards and Fast Forward for when you need to set a very large number (e.g. a large battery Ah capacity.)
  • LED backlighting: Makes the display readable in any light conditions.
  • Hidden Wiring: All the wires are covered. Wiring to the unit can be kept out of sight inside the wall or behind the mounting panel. This makes for a clean installation. The user gets the access they want without making their living space into a distribution board. Especially valuable in mobile applications.
  • More terminals: A terminal for every wire. Wiring is simpler and quicker. External electrical commoning points or bus bars are not needed and it is easy to understand where the wires should go.
  • Generator Terminals: Voltage free contacts, as required by many generator start systems, are now included in the basic controller.
  • Accessories: The Accessories available so far include shunt adaptors (DSA) and two different data adaptors (DUSB and D232).
  • The DSA reads external charge or load currents: You can use up to 4 per system.
  • The DUSB provides a USB interface to a computer: This allows the user to download all the data from the controller and change settings if required.
  • The D232 provides an RS232 interface (DTE): Designed for remote computer access via a modem.
