Oh No ! I bought a Mppt Solar Controller
I don't believe it ! I bought it and I don't really even want it ! I was sure this would go for more than 12 bucks. Fooled me, oh well. Whats w/ links not working ?

A quick simple test would be to measure the array voltage and the battery voltage while in operation. I assume your 130watt panel has about 17Voc and maybe 15Vmp depending on the light/heat conditions. If you measure the array voltage it should be close to 15 volt mark while the battery should be charging at a lower voltage. If there is no difference then ...... after all it was only $20.00
