Step 9: Adding Another Battery
I know I had mentioned this in my previous post, but now I actually made a move on it. The problem with my system right now is that the battery is too small for the amount of panels I have pumping juice into. By 9:00 AM the next morning, that battery is fully charged. I'd like to run more stuff at night to pull down the battery down more, but I'm limited because of the lack of capacity. Running cell phones and lights at night was enough to drain the battery, but not enough that the panels couldn't recharge it easily the next day.
Note: Even though I could continue to use the system like this, I would be wasting valuable sunlight hours where the battery is full and I have no need for the power. Really counts when I need the power and don't have any, plus I'm kicking myself at night when I have to shut down loads while I sat and watched the power go to waste all day.
The new battery is at 86 a.h. compared to the previous 104 a.h. battery I got earlier. That's a total of 190 amp hours for those of you who can't do math in their heads. BECAUSE a battery should never be discharged below 50%, I basically have 95 amp hours to play with. Still, this is significantly more than the 52 I had before. I still would like to purchase more batteries, so I will still continue searching for good deals.
