This design requires the battery can supply a higher current. For this design we will be using 2 100Ah LiFePO4 batteries.

Solar Charge Controller
Model: ALLPOWERS 20A Solar Charge Controller Solar Panel Battery Intelligent Regulator-Blue
The solar charge controller is responsible for charging the battery from the solar cells.
Q: What battery type is this controller supported?
A: (1)B-01=LEAD-ACID, 12V; B-02=LITHIUM ION 3s, 3*3.7V=11.1V; B03=LIFePO4 4s, 4*3.2V=12.8V. (B01 is the default type, If you would like to to switch to another 2 types, please select it manually.)
|b02||Lithium Ion 3S (11.1V)|
We will be using the b03 setting for LiFePO4 4S.
We have a flexible 100 watt solar panel from AllPower.
We will be using 2 DIY 100 Ah LiFePO4 Batteries.
|Nominal Voltage (4 x 3.2v)||12.8v|
|Max Voltage (4 x 3.6v)||14.4v|
|Min Voltage (4 x 2.5v)||10v|
|Max Current Output||100A|
The DC-DC Step down converter will be used to charge the battery while driving. The output will be set to a maximum of 14.4v.
Our inverter is a 3000W Motomaster modified sine wave inverter. We don't use a lot of AC and we had this laying around. This inverter in not suitable for sensitive equipment since it is not a pure sine wave inverter. At some point, I may upgrade to a pure sine wave inverter.
