Choosing the Correct Cable Size for a DC Circuit
This is part 1 of a 2 part series.Choosing the right cable size for your DC electrical project is important, since a wire that is too small can overheat and possibly start a fire. The American Boat and Yacht Council (ABYC) publishes charts with valuable detail to help experienced electrical installers determine what wire size

What Size Battery Charger Should i Install?
Battery charger size is based on the overall battery capacity that you have as well as allowing for what loads you would normally run when the battery charger is operating. The key to any battery charger is the basic operation. When a charging source is operating, it will supply all of the DC loads first

How Much Solar Do I Really Need?
This is a question we get asked every day. With most caravaners these days spending more time off the grid compared to being plugged in at a caravan park, solar becomes their primary charging source. Caravan manufactures today are generally installing a single 150w panel on their on-road caravans and 2 x 150w panels with

Can I charge my lithium battery with a lead acid charger?
Can I charge my lithium battery with a lead acid charger? This is a question we get asked every day by the general public. Lithium batteries are not like lead acid and not all battery chargers are the same. A 12v lithium LiFePO4 battery fully charged to 100% will hold voltage around 13.3-13.4v. Its lead

I have a DC charger in my caravan, but it doesn’t seem to charge properly
I have a DC charger in my caravan, but it doesn’t seem to charge properly? With pretty much all new vehicles these days running smart alternators, the requirement for DC chargers has increased exponentially. The biggest problem we see with DC chargers not operating correctly in caravans is installations with under-cabling, incorrect circuit breakers and

What’s the largest battery charger I can run on my 1kVA generator?
What’s the largest battery charger I can run on my 1kVA generator? This is another question we get asked regularly. Taking the most popular 1kVA generator on the market today (Honda EU10i), this unit can produce a maximum output (for a short period) of 1000Watts. Continuous running, the EU10i can operate at approx 800Watts maximum.

What size Inverter can I use on my lithium battery?
This is a question we get asked all the time. The size of the inverter is really dictated by the loads that you want to run. Let’s say your largest load is a microwave. A typical microwave will draw between 900-1200w. With this load you would install a minimum of 1500w inverter. This size inverter

Are Your Batteries Constantly Going Flat?
Are Your Batteries Constantly Going Flat? A large portion of DC power systems these days don’t come with any protection to stop the battery from being completely drained away when loads are running. Over discharging a battery can and will shorten its overall lifespan and performance. By simply installing a “Low Battery Cut-Out” device in

Does battery voltage alone tell me how full my batteries really are?
In short yes. It’s not an exact science but battery voltage will give you a very rough indication of battery capacity. Lithium on the other hand is extremely difficult to determine capacity due to the very flat voltage curve that lithium batteries have. Let’s look at this a little differently. You’re out in an isolated
