OFF-GRID CARAVAN: Running Aircon + More With 600Ah Lithium & Solar! (Includes Cerbo GX 70 Tutorial)

Isaac walks us through our customer's brand new @leadercaravans RV, where we recently installed an epic energy system featuring 600Ah lithium battery storage, 600W rooftop mounted solar, and a touchscreen monitoring system with the crowd favourite @VictronEnergyBV Cerbo GX Touch 70.

Our customer wished to travel off-grid without compromising on comfortable living, so we designed and installed a solar and battery system that could power all their necessary appliances (including air conditioning, lights, kitchen appliances, and more) from anywhere in Australia.

The system features:

- x2 300Ah 12V @enerdrive-dometic B-TEC Lithium Batteries

- @VictronEnergyBV Multiplus-II 12/3000/120-32

- Victron Cerbo GX Touch 70

- Enerdrive 12V 40A DC-DC Charger

- Victron SmartSolar MPPT 100/50

- Victron SmartShunt 500A

- x2 @ALVOLTA 12V 200W Mono Solar Panel

Thank you' great video' and information!🖖

How safe are these Lithium batteries though? Do many of these big batteries fail and start fires like some of these other lithium battery accidents? Also, how much did that system cost?

The biggest question Aussie caravaners want to know is what off-grid system will run the aircon (cooling mode set at say 22-23deg in hot weather) when camped up in a non powered camp site.
Aware of different draw loads from aircons but lets assume the aircon is not the latest technology type like the newer Dometic Harrier Lite or plus units. And the caravan is 19ft or less in size and not a modern composite made van buit instead alloy clad to keep it simple. Our caravan is a Coromal 18ft 2005 model with its original installed wall mount internal aircon control unit and the compressor mounted seperate inside a lower kitchen side cupboard in its own compartment vented to the external wall.
Most people are referring to use at night when they want to sleep at confortable temp on still balmy warm nights

What was the aprox cost to this 600ah system complete (not including your instal fee) and any idea of total weight it added to the van? Thanks

What are the two different type of solar panels on the roof, and how do they differ in performance?

[aaronpitts]

Why are the panels only produce 30amps at 600w?
That seems very low to me. Also you should aim for a minimum of 80amps from the panel's to be sufficient with this set up.
And the solar charger should provide maximum amps when the AC load is on, not when the battery level falls too low. I can help with this stuff.

Is there a difference between RV Solar panels and home domestic panels? These days a single home domestic panel can be spec’d up to 440watts. The RV panels don’t seem rated the same.

[MrJdwalton]

How does this set up comply with standards of not having lithium battery’s not sealed and vented from habitable areas ? Confused

[bobcatman]

In my caravan I can run my air conditioning with a 600ah lithium battery it draws around 100 amps I also have 2x inverters 150/70 amps each and 1600w solar on the ground producing 120 amps enough to keep the aircon going all day I also have another 600ah just to run my 12v system with another 900w solar and another 2x solar chargers to recharge the batteries

[MarkCleeve-bkzk]

Hi price for the system installed thanx

[marnibarratt]

definitely not enough solar, you should have a ratio of atleast 2 to 1 so 600ah - 1200w of solar

[GardenEdenPermaculture]

Amazing! Do you also have data with which percentage of the battery, how much degrees you are able to cool? It's for sure an expensive setup and even with 600Ah Battery your only able to run the AC for 8 hours, without counting in the solarsystem. So I'm curious how it does play out in practice

[tonirex]

GREAT SYSTEM
but from what i heard anyway you look at it running aircon is a power sucker and not worth paying all this money to run an aircon for a few minutes here and there

[marnibarratt]

maybe he has a 600w solar blanket to add on??

[Aphony]

Fail! 2 to 1 ratio people. For every 1 amp of batyery power you nerd 2W of solar input.

[cheesygamerz]

Sleeping on top of all that lithium power? No thank you lol

[leob]

looks cool but very expensive setup. Just buy a generator....you go off-grid anyways ...no neigbours scream at ya😁
