Will these 48v solar components work with my panels and 12v distribution box

[ToddVolt]

Hi There,

I'm trying to build out a solar charging system for our 2002 25' Bluebird bus and I have a couple questions:

Here's what I currently own:
4 of the following solar panels:
CSUN 310W solar panels. 60 cell all black monocrystalline
Specifications:

• Rated Power: 310W
• Open circuit voltage (VOC): 40.0 V
• Max power voltage (VMP): 32.6 V
• Short circuit current (ISC): 9.83 A
• Max power current: 9.52 A
• Maximum system voltage: 1000VDC
• Fuse Rating: 20 A
• IP67 Junction Box with bypass diodes and standard solar connectors
• Weight: 40.34
• Dimensions: 64.57" x 39.00" x 1.38"

They are wired to the following roof combiner box: https://amsolar.com/rv-combiner-box/20-roof
after I purchase a 48V inverter and battery I want to run my 12v DC appliances off of the following distribution box:

DC Distribution Kit for AGM or Drop-In Lithium Batteries

This kit includes everything you need to connect DC loads to a battery bank. A Victron Battery Protect prevents the batteries from be overly discharged.

I want to purchase an MPP Solar all-in-one inverter because Will Prowse (

) said they're good quality so from his website I picked this one: https://watts247.com/product/pip-3048lv-mk/ and the following 48V battery because DavidPoz (

) said it was a good one:

Questions:
1. Will the solar panels charge the MPP Solar all-in-one inverter?
2. What device should I buy to step the MPP Solar all-in-one 48 volts down to 12 volts before connect my distribution box: https://amsolar.com/rv-battery-accessories/98-dcdagm?

Thanks,
Todd
