^ what do you mean the float was set to 14.4V? That is not a float voltage for lead acid, float should be around 13.5V. 14.4V is absorption voltage.
But what are you measuring there? Is that the voltage straight off the controller without a...
I have used a slow geared down (like 50 rpms) motor and attach the can to the shaft with a clamp. Just let it rotate for a while.
I wonder if one could use a DA sander strapped upside down without paper, and just have the can touch /rest on...
AFAIU (did some experiments but not 100% sure I recall this correctly):
a PWM controller switch will at first be on full time when the battery has low voltage, say 12V, for max averaged current. Picture that as the controller being a solid wire...
if a lead acid battery especially, you may want to make sure that your controller can go into actual float mode. Remember that PWM controllers are basically just on/off switches and do not have a full DC to DC converter like the MPPT ones.
yes, the second one is probably going to last longer in that it has exterior wiring between the 2 sides, so, easy to fix if the cables were to break (also much less likely than with interior ones). And also probably physically stronger...
quick impression is that the above is inexpensive and inexpensive stuff is probably what you will get. There is not much info there, though. Given that it's 150W nominal, it would probably be big enough for a fridge even if not particularly...
Yes, a generator is easier (at first) if you don't mind the noise, the fuel, and the size/weight, and already have one.
But it's actually pretty simple to set up a solar system if you have a basic understanding of DC wiring and are willing to...
^ 0.4A average looks low to me.
A typical camping fridge uses about 50W to run and is on maybe 1/3 or 50% of the time. Depends on conditions but roughly speaking. So around 20 - 25W average. That makes it look like a 25W panel should do the...
