One diode will always turn on before the other - which can result in burning one diode then the second parallel diode when the load is greater than what a single diode can carry.You actually need a single diode that can carry the entire load.Also - keep in mind - that an average diode will have a .7 (point 7) volt drop. I assume that this is a PWM type but I don't really know.
Previously I experimented with putting the diode on the battery side but I was concerned that it might overcharge the battery so now the diode is on the solar panel side.
However, some solar panels include an internal diode, and some controllers include an internal diode, so adding another one might or might not be needed for that purpose (I don't have the unit and cannot check).
There are many different kinds of controllers and they all work differently. I bought a 100w fan that should take care of this. I have the same kits. I have the same problem...i suspect the inverter portion of the box is always on and may be constantly draining about 10 watts offof the battery. 4 years ago I was foolish enough thinking that the light was all powered by solar for the very first night, and forgot the fact that the battery was fully charged already before I connected it to the solar panel. What's going on?One experiment I did was to simply add a blocking diode on the back of the charge controller. on I have a question that hopefully somebody here can answer. Question: has anyone done this yet.? 2 years ago Op states to place the stripe towards the charge controller. I have the block that u put 8 panels on also but im only getting 15.4 volts outta all this and i have to unhook the box at night because i dont have the diodes on mine yet.

: Like many of us who are interested in solar power, I bought a Harbor Freight 45 Watt Solar Panel kit for about $150 which came with three solar panels, and a charge controller.

The ultimate solution would be to look at the components inside the box and see what it's doing. I initially placed the diode on the battery side but based on recommendations from "evilmunkey", the diode should now be put on the solar panel side. How we sell great tools at the lowest prices We have invested millions of dollars in our own test labs and factories. Thus 24.0 volts through a diode will actually give you a working voltage of 23.3 volts. And we can sell them for a fraction of the price because we cut out the middleman and pass the savings on to you. Just like many found out, the charge controller doesn't appear to be working as we expected. I will be getting two batteries for it. on oh yeah, I also have a little inverter that I would be plugging the fan into.
What about current limiting? For now, I need to move on to the next project with desulfator. However, the excitement was short lived. A 45watt and a 100wat kit.
Since I don't know the charging circuit inside the box, the effect of this added blocking diode on the solar panel and battery charging is not clear. Is there something else I am missing? Quality tools & low prices. This is very much an experiment so be careful not to overcharge. Reply 4 years ago So far it works fine and the battery is actually revived to a certain extent.
