I'm building a combination backup power / audio amp.
I have a 12V / 35Ah battery, a 400W inverter, numerous DC outlets, a cooling fan, and a 2 Channel, 600W amp is on the way. My housing is a 40MM ammo box. I'm going to run 6X9 speakers in two 50cal ammo boxes.
I think that the battery will run out before the party does, so I want to be able to plug it into AC. I'm integrating a charger for that purpose.
I understand that it's a bad idea to run a charger, the battery, and the load on the same circuit. I'm looking for an alternative. Can I use a cheap solar charge controller for this? Or should I use a manual 4PST switch to disconnect the battery and run on the DC power supply?
Any ideas on how to do this safely?
I'd love any other feedback or suggestions on the design / approach.
Thanks very much for any response.
P.S. How much should I worry about grounding the amp or any of the other components? Should I ground it on the box and have a spike protruding out?
