Hello I am using a 300 watt inverter, I am sure it would be considered small to most of the people here that are running >5000 watt systems. However even with such a low rating, I am getting sparks when I connect it to the battery. I did some searching and it looks like Will says you should...

I read somewhere here that inverter/chargers are the way to go and cheaper than buying them separately, but I've found it to be the opposite. The cheapest ones I can find are like $400, while you can get a charger for $50 and inverter for $100. Am I just not searching correctly, or is it only...
