Newbie upgrading inverter--Sparks flew
ok i have 2 85 watt panels 2 12v batteries a 400 watt cobra inverter which runs good just way to small. I have ordered a 1500 watt inverter roadpro when i hooked up the road pro i hooked the ground up then when i touched the + sparks flew and burned a spot on my battery post. I sent it back and amazon is sending me another one. Im wondering if i did something wrong i never even turned the power on to the inverter and made sure i had the + and - wires right. The inverter says for 12v its frustrating me cause i payed for next day shipping and now i have to wait 4 days to get a replacement.
