I'm looking to build out a cargo trailer that can provide power primarily for mobile sound/PA systems at festivals and rallies- and looking for any advice on the general concept, design, or equipment options.
I'd like to be able to supply around ~6kw at 120v AC. But I'd also like to have modularity and some redundancy (even if not full). I am thinking of both fixed rooftop solar on the trailer, as well as having the option for a couple more portable panels that could be hauled out of the trailer and setup when practical.
Basically - I'm thinking of 2 entirely discrete systems in a rolling wooden road case - each having ~7200wh (300ah of LifeP04 at 24v), a Victron Multiplus 24/3000, and an MPPT. This lets me have (2) smaller systems when needed (modularity), and if one goes down for some reason - I could limp along with half power (some redundancy).
For the output side - I am thinking each unit could run a pair of 15a/20a Edison circuits (with appropriate breakers). On the input (charging side) - I'm thinking the solar (both rooftop and portable panels) could be on Anderson plugs for quick reconfiguration. I don't see a need for 30a or 50a shore power - but having 20a Edison input would be nice.
When running units in parallel like this -what grounding considerations do I need to think about? They would be powering different devices on different circuits - but those devices would often be grounded/connected via audio lines. Should I bond the inverters together? Or bond the various AC outlet grounds?
And lastly - any advice on the grand plan? Should I just do a single larger inverter and keep it simple? Connect batteries into a single bank and both inverters share that?
Thanks in advance!
