Hi, again,

One more bad experience I have now - during building TX box I used MPPT controller for only 5A like this:
MPPT Solar Panel Charge Controller
I don't know where I bought it, but it was functional only 30 minutes (very sunny day). After this the battery has more than 17 V and "cooked". I think the current was more than 5 A, but didn't meassure it. Now the controller is broken

So - be careful. In very hot and sunny days the energy from solars can be too high!

Regards
