  • Keep in mind that the numbers above vary a lot with weather. On a hot summer day, we use more power (because of the fridge and fans) and on a cool day we use less power than what we calculated above.
  • In winter the fridge and the fans use much less power, but the Webasto uses more. Therefore our daily power usage is quite similar!
  • From now on, we will work with the largest value only (winter in our case):
0 Ah
Daily Power Usage

Step 2: Inverter

The size of our inverter might impact our battery bank. Indeed, inverters draw a huuuge amount of current and our battery bank might not be able to handle it. So it’s a good thing to decide on our inverter size now. The goal here is to calculate what is the maximum power that we’ll ever need at any given time. To find out, we add the power of each loads we plan on using simultaneously.

Thinking of using that induction cooktop (e.g. 1800W) and microwave (e.g. 1800W peak) at the same time? That would require an inverter of about 4000W! Don’t get us wrong it can be done, but that’s an absurd amount of power for an off-the-grid system and its quite dangerous (over 350A of current) if your connections are not perfect…  By using these appliances one after the other, you can go with a 2000W inverter which is more reasonable… 🙂

Simultaneous 120V AC Loads:
LOADDESCRIPTIONMAX POWER (W)
Milk FrotherNespresso Aeroccino550W max
Laptop 1Asus90W max
Laptop 2HP45W max
TOTAL 685W max

A “685W” inverter would be our absolute minimum, but it’s a good idea to keep some buffer so we went for:

1000W Samlex Pure Sine Inverter

Step 3: Battery Bank

3.1- Sizing the battery based on Daily power usage

Sizing a battery bank is not an exact science, as it’s influenced by parameters we don’t have control on (weather) and personal parameters (driving habits and access to shore power). Notice that battery size (capacity) is expressed in Ah. That’s why we calculated our daily power usage in Ah (not in Wh); it’s more intuitive that way!

3.1.1- Recommended Battery Bank

How many days without solar are you willing to accept? 4 days overcast can happen, so our battery bank should have enough power to go through this:

Lithium
  • 4 days autonomy
  • (Daily Power Usage x 4)/0.8*=
  • 355Ah
*Most economic Depth-of-dischage (DOD) for Lithium is 80%
AGM
  • 4 days autonomy
  • (Daily Power Usage x 4)/0.5*=
  • 568Ah
*Most economic Depth-of-dischage (DOD) for AGM is 50%

Hughhh wait! That’s a MASSIVE battery bank for our needs… It’ll use quite a lot of space and the initial cost will be HUGE! If we invest in a B2B charger (alternator charging), we don’t rely on weather alone and it’s reasonable to aim for 1.75 factor. Why 1.75? Again this is not exact science, but this value is a good rule of thumb and have worked for us…

Lithium Battery
  • (Daily Power Usage x 1.75)/0.8 =
  • 155Ah
Recommended Size
AGM
  • (Daily Power Usage x 1.75)/0.5 =
  • 249Ah
Recommended Size

That makes much more sense. And by reducing our battery bank size, the B2B charger just paid for itself!

3.1.2- Sun Seeker (Or Heavy Driver) Battery Bank

Planning on using your van only in summer or along the sun belt? Like to drive a lot? Use a factor of 1.5:

Lithium
  • (Daily Power Usage x 1.5)/0.8 =
  • 133Ah
Sun Seeker Size
AGM
  • (Daily Power Usage x 1.5)/0.5 =
  • 213Ah
Sun Seeker Size

3.1.3- Snow Chaser Battery Bank

Planning on using your van to chase the snow? Ride on! Use a factor of 2:

Lithium
  • (Daily Winter Power Usage x 2)/0.8 =
  • 178Ah
Snow Chaser Size
AGM
  • (Daily Winter Power Usage x 2)/0.5 =
  • 284Ah
Snow Chaser Size

We fit in the “snow chaser” category, so we need at least:

178Ah

Lithium
Battery Bank (min)

3.2- Sizing the battery base on the inverter

Here we want to make sure that the inverter is not drawing more current (amps) than the battery is able to deliver safely. For example, let’s take a Samlex 1,000W inverter hooked up to one (1) 100Ah BattleBorn Lithium battery:

3.2.1- Worst Case Scenario
1,000W Inverter
  • Max power / Lowest voltage / Peak Efficiency (see spec sheet to find these values)
  • 1,000W/10.7V/0.85 =
  • 110A
Inverter Continuous Current
100Ah Battle Born Battery
  • Allowable discharge current (per spec sheet):
  • 100A continuously
  • 200A for 30 seconds

Worst case scenario, a 1000W inverter draw more current  (110A) than what a 100Ah Lithium battery can take (100A max). BUT, it’s quite unlikely that the inverter will be used continuously within that “worst case” range… So maybe we can be more reasonable:

3.2.2- "Real-Life" Worst Case Scenario
1,000W Inverter
  • Power / Voltage / Efficiency (based on "common sense" values)
  • 950W/11.5V/0.85 =
  • 97A
Inverter Continuous Current
100Ah Battle Born Battery
  • Allowable discharge current (per spec sheet):
  • 100A continuously
  • 200A for 30 seconds

We conclude that a 1000W inverter can be used with a single 100Ah Lithium battery. We reach out to Battle Born Batteries and they concur with that conclusion. Here’s a quick and dirty formula that’s easy to remember:

3.2.3- Rule of Thumb
Minimum Battery Size for Inverter:
  • = Inverter Power / 10
(AGM can actually deliver more current without hurting them, but you would go down to 50% SOC way too fast)

We’re going for Lithium batteries and we fit in the “snow chaser” profile, so we need at least 178Ah. We’d rather have excess power than not enough, so we went for:

2 x 100 Ah Battle Born Batteries

Step 4: Solar Power

4.1 Solar Panel Wattage

Solar input varies with weather, seasons, location and where you park (full sun VS shade). So again, it’s not a precise recipe…

Rule of Thumb:

EACH 4W OF SOLAR PANEL IS ABLE TO HARVEST 1Ah PER DAY.
SOLAR PANELSDAILY HARVEST
100W25Ah
175W44Ah
200W50Ah
300W75Ah 

It means that if we want to harvest 71Ah per day, we need (71Ah x 4W/Ah)= 284W of solar panels. Now keep in mind this is a broad rule, so we will harvest more in summer and less in spring/fall.

Sun Seeker Solar Power
  • Daily Power Usage x 4W/Ah x 0.8 =
  • 227W
Recommended Solar Power
  • Daily Power Usage x 4W/Ah x 1 =
  • 284W
Snow Chaser Solar Power
  • Daily Winter Power Usage x 4W/Ah x 1.2 =
  • 340W

About winter: In December and January, solar is pretty much inexistant (because of the sun angle, short solar day and snow on the panels) so more solar panels won’t really help. But more solar panels does help a lot in late October/November and in February/March. That’s why we recommend more solar for snow chasers…

4.2- Solar Charge Controller

Victron makes excellent solar charge controller at an honest price, so we don't see reason to go see somewhere else... So here are Victron recommendations:
Nominal Power (W)Victron Solar Charge Controller (click to see on Amazon)
0-145W75|10
146-220W75|15
221-290W100|20
291-440W100|30
441-700W100|50
701-860W150|60
861-1000W150|70

We fit within the “Snow Chaser” profile, so we need at least 340W solar power.  In 2016, 2 x 160W panels is what we could find, but today we would go with:

- 2 x 175W Newpowa Solar Panels
- Victron 100|30 SmartSolar Solar Charge Controller

Step 5: Alternator Charger

We don’t like driving for no reasons, but having the ability to charge from the alternator can drastically reduce our battery bank size and we don’t depend on weather anymore.

There are two requirements to fulfill:

1- Battery Recommended Charge Current
(per spec sheet)
Rule of thumb:
  • LiFePO4: Up to 0.5C (50% of capacity)
  • AGM: Up to 0.2C (20% of capacity)
2- Don't exceed the Alternator Available Power (or "Unused Power")
Depends on vehicle & alternator option

In our case:

2 x BattleBorn Batteries wired in parallel
  • 50A recommended charge current for each battery wired in parallel.
  • 50A x 2 =
  • Up to 100A
Ford Transit with heavy-duty alternator (230A)
  • Alternator power - Ford Transit own power needs.
  • 230A - 80A* =
  • 150A
Alternator Available Power
*80A value obtained from fordtransitusaforum.com (unofficial source)

We could go up to 100A, but we went with:

Step 6: Shore Charger

Together, we’re designing an electrical system of an off-the-grid vehicle. So honestly, you probably don’t need shore power, except…

Consider adding shore power if:
  • You're a snow chaser with an AGM battery (finishing the absorption phase takes a long time and it's important for the battery's life cycle).
  • If spending extended time at friend's house, relative's house or at full-service campground (it's nice to just plug in and forget about the battery)

It’s the same requirement as for the alternator charger, except this time we’re not limited by the vehicle alternator available unused power:

1- Battery Recommended Charge Current
(per spec sheet)
Rule of thumb:
  • LiFePO4: Up to 0.5C (50% of capacity)
  • AGM: 0.2C (20% of capacity)

We could go up to 100A (0.5 x 200Ah), but we went with:

about us

Nice To Meet You.

Hello! We’re Isabelle and Antoine 🙂 In 2017 we sold our house (and everything in it), quit our engineering careers and moved into our self built campervan. We’ve been on the road since then and every day is an opportunity for a new adventure; we’re chasing our dreams and hopefully it inspires others to do the same!
