Ultimate Victron & Shervey Off-Grid Power System in a Willow Caravan

Ben from Solar N Sat runs through the massive 24 volt Victron and Shervey Power Products Off-Grid system that the team installed in this brand new Willow Waratah Caravan.

For almost 20years we have been designing and installing RV power systems, would you risk your pride and joy to anyone else?www.sherveypowerproducts.com for products or www.solarnsat.com.au for installations

Hey Ben, thanks again for mine Adam and Jessica willow boab 629, fit out we absolutely love your workmanship, faultless 👍

Great run through of the system. Would be great to have the overall cost shared in the videos.

One hell of a setup

Why no smart shunt for measuring thr DC load side of the system? Also why no gui mods or any wireless temp sensors for things like the fridge, electrical enclosure? Makes automating the cooling fans operation far more seamless vs always on.
Why no alternator upgrade on the tow vehicle? The owner isn’t short of a dollar so being able to completely utilise the dcdc’s seems like a no brainer

Thanks for watching mate!
A Smartshunt wasn't necessary on the DC load side although there can be benefits to accuracy by fitting one. The system already displays the combined in and out on the Touch 70 using the battery side Smartshunt. Especially in such an AC heavy system the DC loads are very minor in comparison.
No GUI Mods because although it's pretty cool, we as a business and Victron Distributor only work with officially supported software for our own installations. The information provided by the official OS is more than sufficient and once the new Venus OS releases everyone will want to upgrade to that anyway.
Temp Sensors are fitted, we also often trigger the fans by temperature (Check out some of our other videos). Since we use silent PC fans though you can't hear them anyway. With the 300000 hour design life too you shouldn't have to worry about wear on them either.
An alternator upgrade is often a great choice, especially when in setups with much larger DCDC charging systems we highly recommend them. (Check out the 24v System we did for our TV Show Exploring Off The Grid, we installed 2x 100A DCDC Chargers that required it) We also have a 79 Series lined up in future that will have multiple Orion 12/12-50XS's installed to it, it will have an alternator upgrade as well to facilitate that larger load. On this particular job however, to upgrade the alternator for an additional 7-8a of charge didn't feel worthwhile.
The battery bank is currently only running at 65% of its maximum charge rate even with every charger running so more charging can definitely be added later if wanted!
