Battery, Solar and Electrical Set Up

Running power from our Batteries to our DC loud is fairly simple. 

12 Volt current flows from our Battle Born Game Changer 3.0 Batteries to our Lynx Distributor 1000DC which acts as a fused bus bar. Positive runs out of the Lynx Distributor on 10 AWG Red Stranded Tinned Wire to a Battery Guardian AutoSelect (BGA225). The BGA225 acts as a safeguard to ensure our DC power load never depletes our batteries below a safe level.

From the BGA225 the positive 10 AWG Red Wire runs directly into the positive in of our DC Fuse Box.  

The negative line runs directly from our  Lynx Distributor on 10 AWG Black Stranded Wire  to the negative terminal of our DC Fuse Box.

We also have a  Orion-Tr Smart Charger connected to our bus alternator. This allows us to charge our Battle Born Game Changer 3.0 Batteries  anytime our bus is running.

We currently have SIX 12V 235W PV Solar Panels installed on the roof of our bus. This gives us a total of 1410W. We plan to double our solar setup in the future and will mirror our functioning solar array and components for the second set. 

Our panels are wired with 3 sets of 2 panels wired in series, then linking those 3 sets together in parallel. Connecting our solar panels this way gives us 48V and keeps our amperage down so we can utilize 10 AWG Solar Cables & 10 AWG Copper Wire continuing on for the system.

Each of the sets of panels connects to our Y Branch Connector Parallel Adapter Wire Plug with Solar/PV 10A Fuse and then head down into the bus through a Weatherproof PV Solar Cable Entry.

From the cable entry we run 10 AWG Copper Wire down to our electrical wall and connect into a 50A DC Isolator Switch, then on to a Fuse Block  with a 100A MIDI Fuse and then on to our SmartSolar MPPT 150/70 TR Charge Controller.

The current from our solar panels is converted in the MPPT Charge Controller and sent across 6 AWG Flexible Stranded Wire with 4 AWG Lugs connecting to our Victron Energy Lynx Distributor 1000DC, which passes the power on to charge our batteries.

Our alternating current comes from the Battle Born Batteries, through the   Lynx Distributor . Inside the  Lynx Distributor,  we have a  400 AMP MEGA Fuse  to the positive output. From there we have our 4/0 AWG Lugs  crimped to 4/0 AWG Red Copper Wire and connected to a 350A  ON/Off  Switch before entering into one of our Victron Multiplus Inverter Charger.

We used 4/0 AWG Black Cable  on the negative side to directly connect into the Multiplus Inverter Charger

From the AC1 out of our Multiplus Inverter Charger we used Standard 6/2 Indoor Electric Cable with Ground to connect to one leg of our QO612L100 Square D Breaker Box.

We have a second Multiplus Inverter Charger which we connect on a separate  400 AMP MEGA Fuse in the Lynx Distributor we a 350A  ON/Off  Switch before entering the second Victron Multiplus Inverter Charger. The second Inverter Charger will then connect to the second leg of our QO612L100 Square D Breaker Box via Standard 6/2 Indoor Electric Cable.

All the components of our system connect to the Cerbo GX via RJ45 Cat6a Cables. The Cerbo will eventually connect to our ethernet network which will make our system information and some controls available via the internet.

The  Cerbo GX  has an optional LED touch screen that allows us to see a system overview (see right) which we have hooked up inside the bus and are mounting in an upper kitchen cabinet door.

We can also monitor the system through the VictronConnect 4 app
via bluetooth connections to each component separately.  The Multiplus Inverter Chargers connect to VE. Bus Smart Dongles which allows for bluetooth monitoring and the SmartSolar MPPT 150/70 TR Charge Controllers and  BMV-712 Battery Monitor have bluetooth built-in.
