Victron enhanced off-grid system

A guest blog by Victron Energy dealer Neosolar & Asolar, who are based in the Czech Republic.

This off-grid system was designed with high reliability and innovative functionality in mind – using Victron Energy products to assist in achieving these goals.

The system has proven itself operationally, having been originally commissioned on 12th February 2016.

DIY ingenuity: Hydro Power in the Austrian Alps

You could be forgiven for thinking Markus Pauritsch is a fireman in his day job. In fact he’s been an IT professional for the last fourteen years, working in their ten employee family business. In my experience IT types like to tinker in their spare time and Markus is no different. His DIY tinkering has led to an off-grid project which has inspired him to get more involved in renewable energy themes and hopefully expand their business into that area.

If ingenuity is anything to go by he’s certainly moving toward that goal – and to my mind takes first prize when it comes to using Victron products in unusual ways.

Now, what about those fire hoses?Continue reading

Lessons learned: Thrusters, Lithium and SOC

Good day,

Calling all dealers, designers and installers.

Recently I’ve been involved in two technical support cases of which I want to share my insights and the lessons learned.

The first is about Battery State of Charge, and especially for systems that include a Color Control GX or Venus GX. The various options can be quite confusing and initially we didn’t have a manual explaining them. We do now!

See the SOC link below. Please take the time to study this carefully. Anyone involved with advising, designing or troubleshooting systems with the aforementioned devices should know this by heart:
Battery State of Charge (SOC)

The second lesson concerns a typical marine topic: bow and/or stern thrusters and their batteries. The conclusion is simple: don’t put thrusters on the house battery, especially don’t do so when using bms protected lithium for the house battery.
The main reasons for that:Continue reading

Building an unattended battery based energy system

Good day!

Lately, I have been involved in several unattended Victron systems. Some of these being large scale containerised systems, such as the one shown above. And now that I think of it; as a system designer or installer you could consider almost all systems as unattended, as there will rarely be a trained Victron technician/installer onsite all of the time.

In that case and in this post I’ll highlight several ideas that I have either seen or that have come to mind whilst helping to make such systems robust and foolproof.
