- 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.
