David Lawson's Fahrzeug (#1275)

The coronavirus has affected my income. Its time for austerity. Things will progress very slowly for a the foreseeable future. I'm still working on smaller pieces as finances allow.

I am experimenting with converting a small AC toploading freezer to an inverter powered refrigerator. So far, the power usage is extremely low. If this works, it will be 1/10th the cost of a dc refrigerator half its size and it can be replaced most anywhere in the USA. The external thermostat is a Johnson Controls A19AAT. I'll clad the top with linoleum or wood and use it for a table top so the space is not wasted. A hard start capacitor and a soft start circuit was added to lower the inrush current on startup. This allows the use of a smaller inverter. It now uses an average of six watt hours continuous and 425 watts on start up. The soft starter controls the startup with an initial 20% voltage which ramps up to 100% over five seconds. The hard start capacitor helps with the reduced voltage.

I think this experiment has been a success. It is low cost, easily replaceable with off the shelf items, has a high capacity, and has a low power drain. I'll tidy everything up and add a trim plate to the open hole left from removing the original thermostat. My intention is to power this with its own small, modified sine wave inverter. These are available almost everywhere in North America.


Stromspannung im Chassis 12 volt and 19 volt
Stromspannung im Aufbau 12 volt
Ladewandler 24-12V 12v
110V / 230V im Aufbau? Ja
Wechselrichter I'm looking for an inverter that is not screaming with rf.
The circuit breaker is installed on the bumper because there is just no room under the hood of a 2019 F-550. Two 2/0 cables are attached to the starter battery bank through a 1/8" x 1" copper bus bar. Power is taken from the circuit breaker to the SB350 connector through a 4/0 cable.

A 12 volt outlet was removed from the dash. This circuit now powers a relayed 12 to 19 volt converter for laptop use. An XT-60 plug was used to keep the 19 volt connection unique.


Volumen der Frischwassertanks 100 gallons
Volumen der Abwassertanks 40 gallons
The highlighted pieces of the rear fuel tank have been ordered separately. It will be converted into skid plate equipped gray water tank.


Hersteller und Art der Toilette Thetford cassette
