Yeah, I would say get an MPPT charger. It will get the most out of your panels.
But, one thing you might want to have is a Battery Tender. To trickle charge the bank.
I have a car that gets little use, so I have to keep it connected to a battery tender.
Instead of buying a sinewave inverter to make 120vac,
you might want to get a car-charger for your phone or Ipad..
Not that you'll have wifi during a blackout.. (Unless you use a Pirate Box).
For lighting, just use 12VDC LED lighting. With car type 12vdc plugs..
Less power wasted in conversion.
You want your PV to have enough power output to be able to fully charge a few phones,
at the same time you are charging the main bank..
Which could be used to power lights and low drain devices at night.
Some people like a small 12vdc fan.. (Women mostly).
