my dump controller

[XOKE]

HI guys

About the charge voltage for my batteries I have tested for 3 days in a very good wind, (sometimes more than 12 m/s) and when they are at rest the voltage don't go up than 12,56 volts,(about 90%)  so for charge this batteries I need more voltage.

I try another source of information, I found the web page of then, send a mail explain this situation and their answer is that I should charge the batteries at 14, 4 volts, because there's a cycle of charging and discharging.

Well next few days when I get home again I`ll set the controller to 14, 4 volts and check it one more time.

HI, I made some new improvements in my dump box; I add a few more resistors, now there are 15 of them.
Now I can dump at 14,4 volts around 1300 watts,
This works fine, last night there's a lot of wind and the battery bank its full charged, and it was dump most of the time, and the resistors get a little warm.

VERY nice! any possibility of adding a small DC fan to move the air around them to help with heat dissipation? Even one on the outside of the gridded door ?
Still VERY nice!!
Thanks for the update.

Hi,
Thanks Bruce S.
I believe theres no need any addicional fan, the box its big enough 50cm x 40cm x 15cm.
thanks
