[QUOTE="condor22, post: 301252, member: 1932"] Great,- Once you use it in anger when out and about, you start to realise what a difference there is in the charging rates of each of the stages, depending on SOC of the battery as well as what is going out. One thing I've done occasionally when on solar is to temporarily turn off your fridge and all loads (when the battery is at least 20% down) at various times of the day and weather conditions. That will give you a real world idea of just what is happening re solar charging. One thing I have had said to me by others is that "my solar panel is only inputting 0.5 amps, it should be putting in 6+". The point is that when a battery is near full, it's being charged in absorption stage at an ever reducing amperage. So although the panel may be outputting 6+ amps, the controller is only allowing a small portion of that to the battery. Conversely, your battery may need to be charged in boost as it's SOC might be 20+% down, and on a dull overcast day, your panel may only be producing 1-2 amps or less. So that is all the controller will charge at, they don't increase the panel output and although it may be a 25 amp charger, that is its maximum and they invariably operate at far less. [/QUOTE]
