A project to add solar power to the VW T3 Joker
|
||||||
|
|
||||||
|
|
||||||
|
**WikiToDo**
|
||||||
|
|
||||||
|

# Conditions
|
||||||
|
**Energy sources**
|
||||||
|
- Starter battery
|
||||||
|
- Leasure battery
|
||||||
|
- Engine
|
||||||
|
- 220 input
|
||||||
|
|
||||||
|
**Energy consumtion**
|
||||||
|
- Pentry fuse 16A
|
||||||
|
- Fridge 85W
|
||||||
|
- Indicator display (oklart men extremt lite. Letar efter källa)
|
||||||
|
- Waterpump (pentry)(12V 2A => 12*2=24W)
|
||||||
|
- Fridge fan (0,6W)
|
||||||
|
|
||||||
|
**Other stuff**
|
||||||
|
- Unsure about the fuse directly at the battery but should use one 8A
|
||||||
|
- Battery charger type LG 20

# The panel
|
||||||
|
**Specs**
|
||||||
|
- 110 W
|
||||||
|
- 18V rated voltage
|
||||||
|
|
||||||
|
# The MPPT
|
||||||
|
**Specs**
|
||||||
|
- ESP32
|
||||||
|
- Diod preventing the protective diods in the box at the back of the panel breaks if the panel is connected with the wrong polarityand preventing old/bad panels to discharge the battery when it is dark. Stuges test shows that this diod will be what limits the effect/power the chager can handle. With a load at 6A he measured 113 °C on the outside of the diod. The it is close to the max temperature (150 °C) on the inside. At a load at 6A he measured 100W in, the used panel in this project is 110W. This is working since the panel never produces 100%. But it is close to the limit if the chager is loaded at 6A.
