How does power flow in my trailer?
Please take a moment to watch the video below for step-by-step guidance, or follow the step-by-step written directions.

1. Sunlight hits the solar panels
-
Solar panels capture sunlight.
-
They convert sunlight into DC (direct current) electricity.
-
The voltage they produce changes depending on conditions:
-
Bright sun: about 18–20 volts
-
Cloudy conditions: about 12–15 volts
-
2. Power goes to the MPPT charge controller
-
Electricity from the solar panels flows into the MPPT charge controller.
-
The controller:
-
Finds the most efficient way to use the solar power
-
Adjusts (“converts”) the voltage to safely charge your batteries
-
Example: 18V from panels → reduced to ~14V for batteries
-
3. Power is stored in the batteries
-
The batteries store the converted electricity.
-
They act like a reservoir of energy for later use.
-
A shunt tracks:
-
How much power goes in
-
How much power comes out
-
Overall battery charge level (state of charge)
-
4. Power is sent to the inverter (when AC power is needed)
-
When you need household-style power (AC):
-
The inverter pulls 12V DC from the batteries
-
It converts it into 120V AC power
-
-
This is what runs normal outlets and appliances
-
Note:
-
The process is about 85–95% efficient
-
Some energy is lost as heat
-
5. Power is distributed throughout the trailer
-
DC power (direct from batteries)
-
Runs:
-
Lights
-
Water pump
-
Fans
-
-
Uses lower voltage directly without conversion
-
-
AC power (from inverter or shore power)
-
Runs:
-
Wall outlets
-
Household appliances
-
-
Goes through:
-
Breaker panel
-
Fuse box
-
-
-
These protect and manage the electrical system
