Skylla-i charger and control panel firmware v2.01

First a short introduction to these chargers. The Skylla-i chargers are our high power and can-bus enabled 24V chargers. There are four models:

  • 24V 80A – 1 output
  • 24V 80A – 3 outputs
  • 24V 100A – 1 output
  • 24V 100A – 3 outputs

And there is a remote control panel, the Skylla-i Control GX:

Skylla-i_Control_GX_front_REC000200000

Read the datasheet for more details about all the different features.

Firmware version v2.01 brings one big improvement, suggested to us by Alan Peng, owner of Shenzhen Royal Technology Co, Ltd, our main distributor in China. Besides seven pre-defined battery modes such as gel, agm and lithium, it has two modes where you can set the absorption voltage, float voltage and maximum charger current with three potentiometers. While adjusting one of these, the voltage will now be indicated by the LED bars on the Skylla-i, and on the numeric display (blinking) on the Skylla-i control panel.

You really have to try it yourself to see how simple and fast it is to set up. This is a huge improvement over the old way,  thank you again Alan!

 

The other changes include:

  • Lithium float voltage changed from 13.35v to 13.5v
  • Improved stability of parallel charging algorithm when disconnecting and reconnecting chargers to the network.

 

Contact your Victron representative for the necessary files. Updating both the charger and the control panel can be done with VE Power Setup, available for download on our software and downloads page. More information on VE Power Setup is available in the VE Power Setup blog post.

Have a good weekend, Matthijs Vader

Matching solar modules to MPPT charge controllers

Life used to be so simple; in a 12V battery system you took a ‘12V’ solar module, watched carefully that the maximum PV current would not exceed the charge controller maximum current and the system would work.

Unfortunately due to the fact, that with PWM controllers the PV module is not feeding the battery from its maximum power point (MPP), the system loses a lot of energy. In the following diagram you can see, the area of the MPP in blue  (Vmpp * Impp) is up to 30% larger than the PWM area (Vbatt * ~Isc) within the IV curve. IV curve So, with the advent of the newer Victron Energy Blue Solar MPPTs, things changed for the better when compared to PWM solar charge controllers.Continue reading

Pacific Powerboat magazine: Quattro packs a punch

It’s good to see Victron’s products appearing in magazines, and making a difference to boat owners. This time it is the southern hemisphere’s turn.

When SeaChange, a 15m powercat luxury catamaran from Darwin in Australia, needed an upgrade, Ynovex Pty Ltd., put together a package that gave the boat a whole new lease of life.
