Next Proposal
Due to the limitations of our current battery, we can only supply a maximum of 50A. ThIs will limit what we can run on our inverter. Since we don't use the inverter much at all, this is not critical at the moment.
Ideal
This design requires the battery can supply a higher current.

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.)
| Battery Type | Description |
|---|---|
| b01 | Lead Acid |
| b02 | Lithium Ion 3S (11.1V) |
| b03 | LIFePO4 (12.8v) |
We will be using the b02 setting for Lithium Ion 3S.
Solar Panel
We have a flexible 100 watt solar panel from AllPower.
Battery
We will be using a DIY 130 Ah Lithium Ion Battery.
Specification | Value |
|---|---|
| Capacity | 130 Ah |
| Nominal Voltage (3 x 3.7v) | 11.1v |
| Max Voltage (3 x 4.2v) | 12.6 |
| Min Voltage (3 x 3.0v) | 9v |
| Cell Configuration | 3S 56P |
| Max Current Output | 50A |
DC-DC Converter
The DC-DC Step down converter will be used to charge the battery while driving. The output will be set to a maximum of 12.6v.

Inverter
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.
